Rooflights

Inbuild UK Ltd offers an extensive range of rooflights engineered to optimise natural daylight, enhance ventilation, and improve the overall energy performance of buildings. Suitable for residential, commercial, education, healthcare, retail, and industrial environments, our products are designed and tested to meet all relevant UK Building Regulations and European standards, ensuring compliance, safety, and long-term durability. 

Daylighting & Energy Performance 

Rooflights play a critical role in reducing reliance on artificial lighting by maximising the use of natural daylight. Products from Coxdome, Brett Martin, Fakro, and Dakea are designed to deliver exceptional visible light transmission, improving indoor environments and supporting occupant wellbeing.  

Many of our rooflights incorporate low-emissivity (low-E) coatings, argon-filled glazing units, and thermal breaks to minimise heat loss and solar gain, ensuring compliance with Approved Document L (Conservation of Fuel & Power). These features help achieve lower U-values, contributing to reduced energy consumption and improved EPC performance. 

Ventilation & Indoor Comfort 

In addition to daylighting, Inbuild offers opening and ventilated rooflight systems — available in manual, chain-actuated, or electrically operated models. These units support natural and passive ventilation strategies, improving air quality and thermal comfort while reducing dependency on mechanical systems.  

Opening rooflights can be integrated with Building Management Systems (BMS) or environmental controls, allowing for automated ventilation based on temperature, humidity, or occupancy levels, helping meet the performance standards of Approved Document F (Ventilation). 

Design, Specification & Aesthetics 

Our rooflight portfolio includes fixed, opening, and modular systems, available in a wide variety of sizes, glazing options, frame finishes, and kerb details. Coxdome provides modular flat rooflight solutions ideal for commercialand industrial spaces. Brett Martin offers sleek, flat roof glazing options with superior light transmission and robust sealing performance. Fakro and Dakea rooflight systems combine performance with aesthetic appeal, suitable for both traditional and contemporary designs. 

Standards & Compliance 

All Inbuild rooflights are manufactured and certified to meet or exceed current UK and EU standards, including: 

•  Approved Document L – Energy Efficiency & Thermal Performance 
• Approved Document F – Ventilation 
• BS EN 1873 / BS EN 14351-1 – Performance and Safety of Rooflight Units 
• CE and UKCA Marking for product conformity 

By selecting Inbuild rooflights, specifiers and contractors can be confident in compliance and long-term reliability. 

Summary 

From modular flat roof systems to custom glazing configurations, Inbuild UK Ltd delivers certified, high-performance rooflight solutions that enhance building design, improve occupant wellbeing, and support full compliance with UK Building Regulations. Our focus on quality, certification, and specification support ensures each project benefits from optimal performance, aesthetics, and long-term value. 

Rooflights are glazed units installed on flat or pitched roofs to provide natural daylight and ventilation. They help improve indoor lighting quality, reduce reliance on artificial lighting, and contribute to better energy performance.

Yes. All Inbuild rooflights are fully compliant with UK Building Regulations, including:

·       Approved Document L for energy efficiency

·       Approved Document F for ventilation

·       Relevant BS EN standards for performance and safety

Absolutely. By allowing natural light into a building, rooflights reduce the need for electric lighting. High-performance glazing with thermal breaks and low-E coatings also reduces heat loss, helping meet energy targetsunder Part L.

Yes. Inbuild supplies both fixed and opening rooflights. Opening models can be manually, chain, or electrically actuated to provide controlled natural ventilation and improved indoor air quality.

We offer rooflight products from leading manufacturers such as Coxdome, Brett Martin, Fakro, and Dakea — each known for their quality, durability, and compliance with UK and EU standards.

Yes. Our actuator-driven rooflights can be integrated with modern Building Management Systems (BMS) for automated ventilation and energy control.

Yes. Many of our rooflights are ideal for replacing outdated units, improving insulation, daylight, and overall building efficiency without major structural alterations.

Our rooflights feature double or triple glazing options that can achieve U-values as low as 1.0 W/m²K, depending on configuration. These values comply with Approved Document L of the Building Regulations for energy efficiency.

Yes. Rooflights can help achieve recommended daylight factors as set out in Approved Document O and BS 8206-2, supporting visual comfort and wellbeing in habitable rooms.

Yes. We supply models designed for both flat roofs (such as Coxdome and Brett Martin) and pitched roofs (such as Fakro and Dakea). Each product is manufactured and tested for its intended roof pitch range.

Minimal maintenance is required. Regular cleaning of glazing and inspection of seals or flashing ensures optimal performance and prevents water ingress. Opening models should have actuator systems checked annually.

Yes, subject to planning approval. Our manufacturers offer discreet, slim-profile rooflights and custom finishessuitable for conservation and heritage projects, while maintaining thermal and ventilation performance.

Yes. Many of our glazing options include laminated or acoustic glass to reduce external noise — ideal for urban or high-traffic environments.

Standard and custom sizes are available. Modular systems (e.g., Coxdome or Brett Martin) can cover large spans, while Fakro and Dakea units suit smaller or pitched applications.

Yes. Rooflights from Inbuild’s partner brands typically come with manufacturer warranties ranging from 10 to 20 years, depending on the model and configuration.

Yes. With the right glazing (e.g., solar-control or tinted glass) and ventilation strategy, rooflights can reduce overheating risk — helping meet Approved Document O (Overheating) requirements.

Yes. All Inbuild rooflights carry CE and UKCA markings, certifying conformity with relevant UK and European performance, safety, and manufacturing standards.
