Rooflights That Meet Part L Standards
Bring natural light into your designs without compromising on thermal efficiency. Discover how LAMILUX rooflights and glass roof products balance compliance and comfort.
Natural daylight is one of the most desirable elements in building design – improving occupant wellbeing, productivity, and energy savings. Yet, rooflights are often the first design feature to be cut, risking both comfort and performance.
With the latest Part L Building Regulations setting stricter standards for energy efficiency, rooflight specification has never been more important. The wrong system can cause heat loss, excessive solar gain, and higher carbon emissions. The right one can transform both spaces and energy performance.
At LAMILUX UK, our rooflights are engineered to optimise daylight while meeting, and exceeding, energy requirements. Key benefits include:
- Superior insulation (low U-values): Keep warmth inside during colder months.
- Balanced solar control (g-values): Prevent overheating while maximising light.
- Outstanding airtightness: Eliminate draughts, reduce energy waste, and protect interiors.
- Thermally broken frames and insulated kerbs: Prevent cold bridging and heat loss, ensuring the glazing’s performance isn’t undermined – a standard often missing from many rooflight systems on the market.
- Smart design options: From advanced glazing and shading to ventilated systems, our solutions adapt to any project need.
We also offer a RIBA-accredited CPD that explores how Part L impacts rooflight specification and building performance in greater detail. This session provides architects and contractors with practical guidance on meeting compliance without compromising on design.
