Introduction

Lighting is an important part of industrial and commercial building design.

Factories, warehouses, logistics centres, manufacturing plants and Pre-Engineered Buildings need adequate illumination for safe and efficient operations.

A building that depends entirely on artificial lighting can have significant daytime lighting requirements. Roof Light Systems provide another approach by introducing natural daylight through selected translucent sections of the roof.

Roof Light Systems in Pune are therefore suitable for industrial buildings where natural daylight, roof integration and practical building performance are important considerations.

A Roof Light System uses translucent roofing components or skylight assemblies to allow daylight to enter the building. The system can be integrated with industrial roofing sheets, PEB structures, warehouses, factories and manufacturing facilities. The supplied Buildtech article describes these systems as daylighting components installed within roofing structures to bring natural sunlight into buildings.

Buildtech Roofing Solutions positions Roof Light Systems as part of its broader Daylighting Systems portfolio, alongside polycarbonate and FRP daylighting products.

What Are Roof Light Systems?

Roof Light Systems are specially designed daylighting components installed within a roofing structure.

Their primary purpose is to allow natural daylight to enter an enclosed building through selected roof areas.

They can be integrated with:

Industrial Roofing Sheets
PEB Structures
Warehouses
Factories
Logistics Centres
Commercial Buildings
Manufacturing Facilities

The basic concept is simple:

Opaque Roofing + Translucent Roof Light + Supporting Structure = Industrial Daylighting System

The translucent section allows daylight to enter while the surrounding roofing continues to provide the primary roof enclosure.

Why Roof Light Systems Are Important

Large industrial buildings frequently have limited opportunities for daylight through conventional windows.

This can create:

Dark internal areas
High dependence on artificial lighting
Poor daylight distribution
Higher daytime lighting requirements
Less visually comfortable work areas

Roof Light Systems address the daylighting component by introducing natural light from above.

Main benefits include:

Natural daylight
Improved visibility
Reduced reliance on artificial lighting during suitable daylight conditions
Better workplace illumination
Support for sustainable building design
Potential reduction in daytime lighting energy demand

The supplied Buildtech content specifically identifies reduced electricity bills, improved visibility, workplace environment, sustainable design and productivity as key benefits.

How Roof Light Systems Work

Roof lights are strategically positioned within the roofing system.

Sunlight passes through translucent panels and enters the building.

The internal roof and floor areas then receive natural illumination.

A simplified arrangement is:

Sunlight → Translucent Roof Light → Industrial Building Interior → Natural Illumination

The effectiveness of the system depends on factors such as:

Roof orientation
Roof-light area
Light transmission
Building height
Internal layout
Weather conditions
Roof geometry
Interior reflectivity

Therefore, Roof Light Systems should be planned rather than installed randomly.

Types of Roof Light Systems

Different daylighting configurations can be used depending on the building and roofing design.

1. Polycarbonate Roof Light Systems

Polycarbonate is one of the daylighting materials used for roof-light applications.

The supplied Buildtech source identifies the following characteristics:

High impact resistance
UV protection
Excellent light transmission
Long service life

Typical applications include:

Warehouses
Factories
Commercial buildings

Polycarbonate roof lights are particularly useful where the project requires a lightweight translucent material with good impact performance.

2. The FRP Roof Light Systems

FRP means Fibreglass Reinforced Plastic.

FRP roof lights can be used as translucent roofing sections in suitable industrial applications.

The supplied Buildtechroof material identifies:

Corrosion resistance
Lightweight construction
Cost effectiveness
Good daylight transmission

Typical applications include:

Industrial sheds
Manufacturing units

This makes FRP a useful option when industrial daylighting and profile-compatible roofing are required.

3. Continuous Ridge Skylights

Continuous ridge skylights are installed along the roof ridge.

They can provide daylight from the highest portion of a large industrial roof.

Potential advantages

Uniform daylight distribution
Enhanced natural lighting
Distinctive roof appearance
Suitable for large industrial buildings

They can be particularly relevant to:

Large factories
PEB buildings
Industrial sheds
Large warehouses

The supplied source specifically identifies continuous ridge skylights for large industrial buildings and PEB structures.

Dome roof lights use a raised skylight structure.

Their geometry can provide a larger daylight-capture surface than a flat translucent panel.

Potential benefits

Increased daylight entry
Brighter interiors
Architectural appearance
Suitable for selected commercial or industrial applications

The final design should consider the roof structure, weatherproofing and installation requirements.

5. Ventilated Roof Lights

Ventilated roof lights combine two functions:

Daylighting + Ventilation

The supplied Buildtech content identifies:

Daylighting
Heat extraction
Improved airflow

as their principal benefits.

This can be useful for industrial buildings where natural daylight and high-level air movement are both required.

Key Benefits of Roof Light Systems

1. Natural Daylight

The primary benefit is obvious but important: Roof Light Systems introduce natural light into enclosed spaces.

This can improve visibility in suitable:

Production areas
Storage areas
Circulation zones
Workshops
Warehouse areas

2. Reduced Dependence on Artificial Lighting

When sufficient daylight is available, a building may require less artificial illumination during daytime hours.

The actual reduction depends on:

Roof-light area
Light transmission
Building orientation
Operating hours
Interior layout
Artificial-lighting controls
Weather

Therefore, Roof Light Systems should be described as a solution that can reduce reliance on artificial lighting, rather than guaranteeing a fixed percentage of energy savings.

3. Potential Energy Savings

Reduced daytime artificial lighting can reduce electricity consumption.

However, the actual financial benefit depends on the building’s:

Electricity tariff
Operating schedule
Existing lighting system
Daylight availability
Lighting controls
Roof-light design

The supplied source identifies energy savings and reduced electricity bills as major benefits.

4. Improved Workplace Visibility

Good daylight can support visibility for workers.

This is particularly useful for:

Manufacturing
Material handling
Inspection
Packing
Storage
Assembly

Better visibility can contribute to a more comfortable and functional work environment.

5. Better Workplace Environment

A brighter interior can create a more pleasant working environment.

Natural daylight can be especially valuable in large industrial buildings where occupants spend long periods indoors.

6. Sustainable Building Design

Roof daylighting makes use of naturally available sunlight.

This can support building strategies aimed at reducing unnecessary daytime artificial-lighting demand.

The supplied Buildtech source associates roof-light systems with sustainable building design and reduced energy demand.

7. Uniform Daylight Distribution

A properly planned roof-light arrangement can distribute daylight more effectively than relying on a small number of side windows.

This is particularly useful in wide industrial buildings.

The exact distribution depends on:

Roof height
Roof-light spacing
Translucency
Interior geometry
Building orientation

8. Long Service Life

The service life of a Roof Light System depends on its material, specification, installation and environmental exposure.

Quality products combined with appropriate installation and maintenance can provide long-term service.

The supplied Buildtech source identifies long service life as a benefit of premium roof-light systems.

Applications of Roof Light Systems

Industrial Sheds

Industrial sheds can benefit from overhead daylight because large roof areas often provide significant opportunities for controlled daylighting.

Roof lights can be positioned above production and working areas.

Warehouses

Warehouses frequently have large roof spans and limited windows.

Roof Light Systems can improve visibility for:

Storage
Picking
Packing
Inspection
Loading
Internal movement

The supplied source specifically identifies warehouses as a major application.

Manufacturing Plants

Manufacturing facilities can use daylighting to improve general workplace illumination.

The lighting strategy should still account for process-specific lighting requirements.

PEB Buildings

Pre-Engineered Buildings are well suited to planned roof daylighting because the roofing system and structural framework can be coordinated during design.

The supplied Buildtech content identifies PEB Buildings as a popular Roof Light application.

Logistics Parks

Large logistics facilities can benefit from daylighting across extensive roof areas.

Roof Light Systems can support daytime visibility in storage and movement areas.

Commercial Buildings

Roof daylighting can also support suitable commercial structures where architectural and functional requirements permit translucent roof sections.

Agricultural Buildings

Roof lights can be considered for suitable agricultural structures, storage facilities and livestock buildings.

Ventilation, temperature control and the building’s specific operational requirements should be evaluated together.

Infrastructure Projects

Large public or infrastructure buildings may also use daylighting systems.

The supplied source identifies airports, terminals and public facilities as potential applications.

Roof Light Systems for PEB Buildings

PEB buildings frequently use large metal roof surfaces.

This makes daylighting an important design consideration.

A coordinated system can include:

PEB Structure

→

Purlins

→

Metal Roofing

→

Roof Light Sections

→

Ventilation

→

Rainwater Drainage

The roof-light profile and supporting details should be coordinated with the PEB roofing system.

Buildtech’s broader product hierarchy includes PEB Structures, Z Purlins, C Purlins, Industrial Roofing Sheets, Ventilation Systems and Daylighting Systems, creating natural internal-linking opportunities between these topics.

Polycarbonate vs FRP Roof Lights

Both materials can serve industrial daylighting requirements.

Feature	Polycarbonate	FRP
Impact Resistance	Excellent	Good
UV Resistance	Excellent	Moderate
Lifespan	Longer	Moderate
Light Transmission	Excellent	Good
Cost	Higher	Lower

This comparison is reproduced from the supplied Buildtech Roof Light Systems source.

Polycarbonate may be preferred when:

Higher impact resistance is important
UV performance is a priority
Long service life is required
Higher light transmission is desired

FRP may be preferred when:

Cost is a stronger consideration
Industrial daylighting is required
Lightweight construction is important
The selected profile is compatible with the roof

The actual product selection should always follow the project’s technical requirements.

The Roof Light Systems vs Artificial Lighting

Roof daylighting and artificial lighting serve different functions.

Feature	Roof Lights	Artificial Lighting
Daytime natural illumination	Yes	No
Electricity for light generation	Not required for daylight	Required
Sustainability potential	High	Depends on system
Daytime operating cost	Potentially lower	Ongoing
Night-time use	Not applicable	Required
Maintenance	Roof system maintenance	Electrical/lighting maintenance

The roof lights do not eliminate the need for artificial lighting in most industrial buildings. Instead, they can complement the artificial lighting system by providing natural illumination during suitable daylight hours.

Roof Light Design Considerations

Effective daylighting requires planning.

Important factors include:

Building Orientation

The roof’s orientation affects solar exposure.

Roof Layout

The location and geometry of roof-light sections influence daylight distribution.

Daylight Requirement

Production areas may require different daylight levels from storage areas.

Climate Conditions

Local weather and solar exposure should be considered.

Roof Height

Higher buildings may require different daylighting arrangements.

Internal Operations

Roof lights should be coordinated with:

Machines
Storage racks
Cranes
Workstations
Electrical equipment
Process areas

The supplied Buildtech source identifies building orientation, roof layout, daylight requirements, climate, roof height and internal operations as key design considerations.

1. Roof Light System Construction

A Roof Light System is not simply a translucent sheet placed on a roof. It is part of a complete roof assembly.

A typical installation may include:

Roofing Sheet → Translucent Roof Light → Supporting Purlins → Fasteners & Washers → Flashing / Closure Details → Sealants → Internal Building Space

Each component has a role in maintaining roof performance.

The roof-light material must be compatible with the surrounding roofing profile. The installation should also provide appropriate sealing so that the daylight opening does not become a source of water leakage.

2. Polycarbonate Roof Light Construction

Polycarbonate is one of the major materials used for roof daylighting.

The supplied Buildtech content identifies polycarbonate roof lights with:

High impact resistance
UV protection
Excellent light transmission
Long service life

Depending on the product design, polycarbonate may be used as a profiled translucent sheet or as a more advanced multiwall daylighting panel.

Important Selection Factors

Before specifying a polycarbonate Roof Light System, consider:

Profile
Thickness
Light transmission
UV protection
Roof compatibility
Required span
Support spacing
Environmental exposure
Installation method

The product should be selected according to the actual roofing assembly rather than simply choosing the highest light-transmission option.

3. FRP Roof Light Construction

FRP, or Fibreglass Reinforced Plastic, is another important daylighting material.

The supplied Buildtech material describes FRP roof lights as:

Corrosion resistant
Lightweight
Cost effective
Capable of good daylight transmission

FRP can be particularly useful for industrial sheds and manufacturing units where a translucent roofing section is required.

FRP Selection Considerations

Consider:

Profile compatibility
Thickness
Translucency
Resin specification
UV/weathering characteristics
Support spacing
Fastener arrangement
Industrial exposure

FRP should be evaluated according to the environmental conditions of the project.

4. Continuous Ridge Skylights

A continuous ridge skylight places a daylighting element along the roof ridge.

This arrangement can be useful for large industrial buildings because the ridge is positioned at the highest part of the roof.

The supplied Buildtech material identifies continuous ridge skylights as suitable for:

Large industrial buildings
PEB structures

and notes their potential for uniform daylight distribution.

Advantages

High-level daylight entry
Long continuous daylighting zone
Suitable for large roof spans
Potentially balanced daylight distribution
Integration with certain ridge arrangements

A ridge skylight should be coordinated with roof ventilation and rainwater-management requirements.

5. Roof Light Profile Matching

One of the most important installation considerations is profile compatibility.

Industrial roofing sheets can have different profiles and geometries.

A Roof Light System should therefore be selected to match the surrounding roof.

Profile matching affects:

Sheet overlap
Fastener position
Water drainage
Sealing
Flashing
Overall roof appearance

A mismatch can make installation difficult and may increase the risk of leakage.

Therefore, before ordering Roof Light Systems, confirm:

Roof Profile + Sheet Dimensions + Support Spacing + Fastener Arrangement

6. Roof Light Thickness

Thickness is an important specification, but it should not be selected independently.

The appropriate thickness depends on:

Structural arrangement
Support spacing
Wind exposure
Roof profile
Material
Installation method
Project requirements

A thicker sheet is not automatically the correct solution for every roof.

Similarly, choosing a very thin sheet solely to reduce cost can affect long-term performance.

The final specification should be based on the complete roof design.

7. Light Transmission

Light transmission is one of the defining characteristics of a Roof Light System.

Higher transmission can provide more daylight, but daylighting design should also consider:

Glare
Heat gain
Internal work requirements
Building orientation
Roof-light area

A well-designed system balances daylight availability with thermal comfort.

8. Daylighting Area

The percentage of translucent roof area should be planned according to the building’s requirements.

Too little daylighting may not provide the intended illumination.

Too much translucent area can increase solar exposure and may affect thermal performance.

Therefore:

More Skylight ≠ Automatically Better Daylighting

The correct quantity depends on the building.

Factors include:

Building size
Roof height
Roof orientation
Internal layout
Operating schedule
Required illumination
Material light transmission
Climate

9. Daylighting and Heat Management

Natural daylight and solar heat can enter through the same roof opening.

This creates an important design consideration.

A successful system should balance:

Light Transmission with Solar Heat Control

The supplied Buildtech daylighting material specifically recommends considering:

Appropriate sheet colour
Diffused products
Controlled daylight area
Roof insulation
Ventilation
Thermal roofing systems
Building orientation

Therefore, Roof Light Systems should be planned together with the building’s thermal strategy.

10. Combining Roof Lights with Roof Insulation

Daylighting and insulation perform different functions.

Roof Light

Provides: Natural Daylight

Insulation

Helps manage: Heat Transfer

Buildtech’s supplied Insulation Solutions structure includes:

PUF Panels
XLPE Insulation
Rockwool Insulation
Glass Wool Insulation
Bubble Insulation
Thermal Roofing Systems
Sandwich Panels

For industrial buildings, the preferred approach is to coordinate:

Roofing + Daylighting + Insulation + Ventilation

rather than treating each component as an independent system.

11. Roof Lights and Ventilation

Industrial buildings can experience heat accumulation near the roof.

A daylighting system can therefore be coordinated with ventilation products.

A possible integrated arrangement is:

Roof Light System

Natural daylight

Ridge Ventilator

High-level air movement

Turbo Ventilator

Air extraction

Roof Louvers

Controlled ventilation

The supplied Buildtech category structure places Turbo Ventilators, Ridge Ventilators and Roof Louvers under Ventilation Systems.

This creates an effective internal-linking opportunity between the Daylighting Systems and Ventilation Systems categories.

12. Roof Lights and Rainwater Management

Roof Light Systems must not interfere with roof drainage.

Water should continue to flow correctly toward:

Eave Gutters
Valley Gutters
Down Take Pipes

The Buildtech hierarchy identifies these products under Rainwater Systems.

During design and installation, check:

Roof slope
Sheet laps
Skylight location
Valley arrangement
Flashing
Drainage paths
Gutter connections

A daylighting opening should never create an unintended obstruction to water flow.

13. Waterproofing and Sealing

Waterproofing is one of the most important aspects of Roof Light installation.

The opening created for a roof-light section must be properly sealed.

Important components may include:

Appropriate fasteners
Sealing washers
Flashings
Closures
Compatible sealants
Correct overlaps

The supplied Buildtech content states that professional installation is intended to provide weatherproofing and leak protection.

However, waterproof performance ultimately depends on the actual product, roof configuration and workmanship.

14. Roof Light Installation Process

A professional installation can generally be organised into the following stages.

Step-1 – Site Assessment

Inspect the building and identify:

Existing roof profile
Roof condition
Roof slope
Support spacing
Daylight requirements
Access conditions

The supplied Buildtech installation sequence begins with evaluating daylight requirements.

Step-2 – System Selection

Select the appropriate:

Polycarbonate roof light
FRP roof light
Ridge skylight
Other compatible daylighting configuration

Selection should consider the complete roof system.

Step-3 – Structural Preparation

Confirm that the roof structure can accommodate the proposed installation.

Check:

Purlins
Supports
Fastener positions
Existing roof condition

For retrofit projects, structural assessment becomes particularly important.

Step-4 – Roof Light Installation

Install the translucent sections according to the selected roofing profile.

Correct alignment is important. The roof light should integrate neatly with surrounding roofing sheets.

Step-5 – Waterproof Sealing

Complete:

Fastening
Overlapping
Flashing
Sealing
Closure installation

The objective is to maintain weather protection around the daylighting section.

Step-6 – Final Inspection

Inspect:

Alignment
Fasteners
Seals
Flashings
Sheet condition
Drainage
Daylight opening

The supplied Buildtech source includes final inspection to verify lighting and waterproofing quality.

15. New Roof vs Existing Roof Installation

New Roof Installation

Installing Roof Light Systems during new construction provides more design flexibility.

The daylighting system can be coordinated with:

PEB design
Purlin arrangement
Roofing sheets
Ventilation
Insulation
Drainage
Electrical lighting

This usually makes system coordination easier.

Existing Roof Retrofit

Roof lights can also be considered for existing industrial buildings.

However, retrofit projects require careful assessment.

Check:

Roof age
Corrosion
Existing leaks
Sheet condition
Structural condition
Purlin spacing
Existing fasteners
Waterproofing
Access requirements

If the existing roof is already deteriorated, it may be more practical to consider the daylighting system as part of a larger roof replacement or restoration project.

16. Roof Light Maintenance

Roof lights should be inspected periodically.

The supplied Buildtech maintenance guidance recommends:

Cleaning roof lights regularly
Inspecting seals
Checking fasteners
Monitoring UV protection layers

Large logistics facilities operate for long hours and often contain extensive storage and movement areas. Strategically placed roof lights can provide natural illumination during daylight hours. This can potentially reduce the amount of artificial lighting required during suitable daytime conditions. The supplied content identifies logistics parks as a Roof Light System application.

1.4 Food Processing Facilities

Food-processing buildings require careful consideration of hygiene, cleaning, temperature and operational conditions. Roof Light Systems may be considered where the roof construction and environmental requirements permit. The selected material and installation details should be compatible with the building’s operating environment.

1.5 Pharmaceutical Facilities

Pharmaceutical facilities have specialised environmental requirements.

Daylighting can be useful in suitable non-controlled areas, but the building’s process, cleanliness, temperature and lighting requirements must determine whether and where roof lights are appropriate.

The supplied Buildtech industries list includes pharmaceutical facilities.

1.6 Textile Units

Textile manufacturing buildings often contain large production areas.

Roof Light Systems can provide natural daylight for general working areas.

The daylighting design should consider:

Instead of replacing an old roof with the same configuration, the project team can evaluate:

Existing daylight levels
Roof condition
Artificial-lighting dependence
Ventilation
Insulation
Drainage
Building use

The new roof can then incorporate suitable Roof Light Systems.

5. Daylighting Strategy for Large Buildings

Large buildings require systematic planning.

A practical approach is to divide the building into zones.

Zone 1 – Production

Determine whether natural daylight can support general work areas.

Zone 2 – Storage

Consider daylight requirements for aisles and material handling.

Zone 3 – Packing

Evaluate visibility and task requirements.

Zone 4 – Circulation

Consider daylight for general movement.

Zone 5 – Specialised Processes

Determine whether controlled artificial lighting is necessary.

This avoids installing roof lights without a clear purpose.

6. Roof Light Placement

Roof Light Systems should be positioned based on the roof and internal building layout.

Important considerations include:

Roof orientation
Roof pitch
Roof height
Building width
Internal obstructions
Machine arrangement

Daylight requirement

The supplied Buildtech source identifies building orientation, roof layout, daylight requirements, climate conditions, roof height and internal operations as key design considerations.

7. Uniform Daylight Distribution

A properly designed roof-light arrangement can help distribute daylight across a large interior.

However, distribution depends on:

Roof-light position
Material transmission
Building geometry
Internal surfaces
Roof height
Sunlight conditions

A continuous ridge skylight may be useful for certain large industrial roofs, while distributed roof-light sections may suit other layouts.

8. Roof Lights and Artificial Lighting

Roof Light Systems should normally complement the building’s artificial lighting system.

During daylight hours: Natural Light → Roof Lights

During low-light conditions: Artificial Light → Electrical Lighting

This provides flexibility.

The supplied Buildtech source describes Roof Light Systems as a means of reducing daytime dependence on artificial lighting.

Therefore, the goal is not necessarily to eliminate artificial lighting.

The goal is to reduce unnecessary daytime dependence where adequate natural daylight is available.

9. Energy-Efficiency Considerations

Frequently Asked Questions

1. What are Roof Light Systems?

Roof Light Systems are daylighting components integrated into roofing structures to allow natural sunlight to enter enclosed buildings. They are suitable for applications such as factories, warehouses, industrial sheds and PEB buildings.

2. Are Roof Light Systems suitable for industrial buildings?

Yes. Roof Light Systems can be used in factories, warehouses, manufacturing facilities, logistics buildings and suitable PEB structures. The supplied Buildtech content specifically identifies factories, warehouses and PEB buildings as applications.

3. Can Roof Light Systems reduce electricity consumption?

Roof Light Systems can reduce dependence on artificial lighting during suitable daylight hours because they introduce natural daylight into the building. The actual energy savings depend on building size, operating hours, roof-light area, daylight availability and the existing lighting system. The supplied Buildtech material identifies reduced daytime lighting dependence as a key benefit.

4. Which is better: Polycarbonate or FRP Roof Lights?

Both materials can be suitable depending on the project. The supplied Buildtech comparison identifies polycarbonate as having excellent impact and UV resistance with a longer lifespan, while FRP is presented as a more economical option with good daylight transmission.

5. Can Roof Light Systems be installed in PEB buildings?

Yes. Roof Light Systems can be integrated into suitable PEB roofing designs. The supplied Buildtech content specifically identifies PEB structures as an application for continuous ridge skylights and Roof Light Systems.

6. Can Roof Lights be combined with roof ventilation?

Yes. Daylighting and ventilation perform different functions and can be incorporated into the same industrial roofing strategy. Buildtech’s hierarchy includes Turbo Ventilators, Ridge Ventilators, Roof Louvers and Metal Louvers under Ventilation Systems.

7. Are Roof Light Systems waterproof?

A properly designed and professionally installed roof-light assembly should maintain the weatherproofing of the roof. Correct overlaps, fasteners, flashings, closures and sealing details are important. The supplied Buildtech installation sequence specifically includes waterproof sealing and final inspection.

8. How much do Roof Light Systems cost in Pune?

The supplied Buildtech source gives an indicative range of ₹190–₹950 per sq. ft. and states that actual pricing depends on material type, roof design, area coverage and installation requirements. This should be treated as an indicative range rather than a fixed quotation.

9. What factors should be considered before selecting a Roof Light System?

Important considerations include:

Building type
Roof profile
Roof structure
Daylight requirement
Material
Roof-light area
Roof orientation
Heat management
Ventilation
Waterproofing
Drainage
Installation requirements
Maintenance

The supplied Buildtech material specifically identifies building orientation, roof layout, daylight requirements, climate, roof height and internal operations as design considerations.

10. Can Roof Light Systems be installed on an existing industrial roof?

They can be considered as part of a suitable retrofit or roof-upgrade project. However, the existing roof, purlins, roofing sheets, fasteners, corrosion, leakage and structural condition should be assessed before installation. Buildtech’s service hierarchy includes Roof Inspection, Roof Retrofitting and Roof Daylighting Installation services.

Conclusion

Roof Light Systems in Pune provide an effective way to introduce natural daylight into suitable industrial and commercial buildings.

Factories, warehouses, manufacturing plants, logistics facilities and PEB structures often have large roof areas. These roofs provide an opportunity to incorporate controlled daylighting through translucent roof-light sections, skylights or other daylighting configurations.

A well-planned Roof Light System can help:

Improve natural illumination
Reduce daytime dependence on artificial lighting
Improve visibility
Support workplace comfort
Contribute to sustainable building strategies
Complement industrial roofing systems

However, successful daylighting requires more than simply selecting a translucent sheet.

The roof-light material, profile, thickness, location, support arrangement, waterproofing, drainage and maintenance requirements should all be considered.

Polycarbonate and FRP provide different performance characteristics. Continuous ridge skylights may be appropriate for certain large industrial buildings. Ventilated roof-light arrangements can combine daylighting with airflow where the design permits.

The strongest approach is therefore to coordinate the Roof Light System with the complete roof.

Roofing + Daylighting + Ventilation + Insulation + Drainage + Waterproofing

This integrated approach can provide a more practical and durable industrial roofing solution.

Buildtech Roofing Solutions’ product hierarchy supports this approach by placing Roof Light Systems alongside roofing, structural, ventilation, insulation and rainwater-management products.

For a new industrial building, Roof Light Systems can be considered during the initial roof design. For an existing building, they can be evaluated during roof inspection, retrofit, restoration or replacement work. The objective should always be to select the appropriate daylighting solution for the actual building rather than applying the same specification to every project.
