Roof Lantern Skylights
What is a Self-Cleaning roof light?
Self-cleaning glass contains a special coating that prevents water adhesion to the glass surface, allowing rainwater to sheet across the skylight and remove accumulated dirt particles, significantly reducing maintenance needs, particularly for hard-to-reach roof installations.

Do I really need Triple Glazing?
Triple Glazed skylights offer impressive thermal performance with U-values as low as 0.6 W/m²K, but the practical benefits may not justify the higher costs for most homes, as quality double glazing often provides sufficient insulation with better overall value.

Will a Lantern Roof Light be difficult to handle and get up onto my roof?
For ease of handling, all of our Lantern Roof Lights are delivered in kit form and leave the factory with all components checked and quality controlled. Your builder or installer will have a comprehensive installation guide with all dedicated parts required for a speedy installation.
What is Light Transmission?
Light Transmission is the percentage of visible light that passes through a skylight's glazing, with higher percentages allowing more natural daylight into your living space, potentially reducing the need for artificial lighting and creating a brighter interior environment.

What is Solar Heat Reflection?
Solar Heat Reflection measures a skylight's ability to return solar energy to the atmosphere rather than allowing it to enter your home, with higher percentage values indicating greater effectiveness at keeping interior spaces cooler during warm weather.

What is a U-value?
U-value, or thermal transmittance, is a crucial measurement that quantifies how effectively a building element prevents heat from escaping or entering a structure. Measured in Watts per square meter Kelvin (W/m²K), this standardised value is particularly important when evaluating the thermal performance of skylights and roof windows.
The U-value specifically indicates the rate of heat transfer through a building component – in this case, a Rubber4Roofs skylight. The lower the U-value, the better the thermal insulation properties and the more energy-efficient the skylight will be. This translates directly to improved temperature regulation in your home and potential savings on heating and cooling costs.
Current UK Building Regulations establish specific U-value requirements for various building elements to ensure energy efficiency standards are met. For skylights and roof windows, existing dwellings must achieve a maximum U-value of 2.2 W/m²K, while new construction projects typically require more stringent values between 1.2 and 1.7 W/m²K, depending on the specific application.
Our premium skylight range exceeds these regulatory requirements, with models featuring advanced glazing technologies that deliver exceptional U-values as low as 0.9 W/m²K in some configurations. This superior thermal performance contributes to reduced energy consumption, a smaller carbon footprint, and enhanced comfort through consistent interior temperatures regardless of external weather conditions.
What is a Thermal Break?
A thermal break is a low-conductivity material layer integrated into a skylight's aluminium frame that prevents the internal frame surface from becoming cold, effectively eliminating condensation problems while improving overall energy efficiency.

What is Low-e Solar Glass?
Low-e solar glass features a special metallic coating that reflects heat back to its source, keeping rooms warmer in winter by retaining interior heat and cooler in summer by reflecting solar heat away, while still allowing natural light to enter.
