Benefits of our Framed Roof lights

Our framed skylights provide numerous benefits for both residential and commercial buildings.

Energy Efficiency

Our skylights offer exceptional thermal performance, ensuring that your building retains heat during winter and stays cool during summer. The double glazed skylights have a U-value of 1.1 W/m²K, and the triple glazed skylights have a U-value of 0.9 W/m²K. This high thermal performance reduces your energy costs, providing long-term savings for your building.


Safe and Secure

Our skylights are designed with safety and security in mind. The non-opening framed skylights and the framed fixed skylights offer high levels of security, ensuring that they are safe from break-ins. Our skylights also have excellent resistance to pendulum body impact, with the double glazed skylight having a rating of 1C2 and the triple glazed skylight having a rating of 1C2/1C2/1B1.


Natural Light

Our skylights allow an abundance of natural light into the building, which can improve the overall atmosphere and provide a sense of openness. This is especially beneficial for darker spaces that require additional lighting, such as corridors, stairwells, and inner rooms.

Easy Maintenance

The self-cleaning feature of our skylights reduces the maintenance required for the building. With our skylights, you can avoid the inconvenience and risk of cleaning the exterior of the windows, as the self-cleaning technology takes care of this for you.

High Light Transmittance

The skylights have high light transmittance with the double glazed skylight having a light transmittance of 81%, and the triple glazed skylight having a light transmittance of 72%. This means that more natural light can enter the building, creating a brighter and more inviting space.

Versatile Design

Our skylights have a versatile design that can fit any building style. We offer framed roof lights, which can add an attractive design feature to any building. The non-opening framed skylights can be installed in areas where ventilation is not necessary. All of these skylights can be customized to suit your specific requirements, allowing for a seamless integration into your building design.
