Energy efficient

Create a greener home

The environment is something that cannot be taken for granted in the 21st Century. Chase Window Company is at the forefront of the drive for energy efficiency and provides the best available systems to keep heat inside your home. Using the very latest in glass technology our Liniar range provides “A” rating in the new government approved Energy Index, certified by BFRC (British Fenestration Rating Council). This is a new development in this industry and we are proud to be taking the lead. Chase Window Company is a keen advocate of greener living and environmental awareness. As such, we are keen to promote the most carbon neutral solutions possible for our customers.

Energy efficient – ensure your home gets an “A” Grade

Operated by the BFRC (British Fenestration Ratings Council), Window Energy Ratings (WER), are a straight forward way of assessing the thermal efficiency of window systems. The rating system is recognised and referred to in Part L of the building regulations.

WERs are calculated using a standard size and style of window and a formula taking into account solar gain and air leakage, amongst other factors. The resulting numerical value falls into lettered bands A-G. “A” being the most efficient. These lettered bands being familiar sights on white goods and new motor vehicles indicating the efficiency of the product.

All calculations are based on the exact same window, the resulting values are directly comparable between window systems. The benefits of installing the most efficient windows in both new build and refurbished properties are obvious, reducing heating bills and reducing carbon emissions.

Whilst some manufacturers of ageing systems are forced into ever increasing levels of complexity and expense to ensure their products achieve acceptable ratings, Liniar products have been designed using the latest techniques to make the most efficient use of materials.
