Energysaver composite panel rooflights provide quality natural daylight in buildings constructed with composite roofing panels. The triple skin rooflight, with a patented thermal membrane, has a U-value of 1.9W/m2K with options as low as 0.9W/m2K, well exceeding the thermal requirements of Part L of the Building Regulations. With full BBA certification these innovative rooflights offer unique features as standard and have been Tried, Tested and Trusted to deliver quick and easy installation, optimum performance and long-life reliability and reassurance.

Compatible with all composite panel roofing systems Energysaver is a factory assembled insulating rooflight (FAIR) and each unit is designed to meet the project specific needs. They are manufactured from Trilite GRP and offer a naturally diffused daylight which is more evenly dispersed than other plastic glazing materials. Distracting shadows, solar glare and hot spots can be eliminated making them ideal for a multitude of industrial, commercial and leisure applications. Delivered to site ready to fit in Ecopac ‘green’ weather protective packaging, Energysavers are light in weight and robust against site handling providing every convenience and potential to save time and labour on site.

Each rooflight is manufactured to tight tolerances to meet the project specification. Standard Energysavers exceed regulatory requirements but where additional performance is required a range of options is available – see table overleaf.
