A-Rated Windows Northampton, Corby & Kettering

Legislation is in place that states that from October 2010, windows installed into existing dwellings need to comply with Approved Document Part L of the Building Regulations. In order to comply the installed products need to achieve a Window Energy Rating Band of C or above and/or achieve an overall U value of 1.6 W/m2k. The Window Installation Company must be able to demonstrate compliance by having its own Window Energy Rating Certification. T&K’s BSI certification (KM 594781) was reawarded in April 2013.

You will find a copy of our recently awarded BSI Certification, which details our full range of energy rated windows, a copy of our BSI window energy rating labels for both our double glazed windows and our triple glazed windows and our Pilkington EnergiKare certification at the following links to our download section.

Our standard double glazed casement window achieves a whole window U Value (Uw) of 1.4 W/m2.K, with a centre pane value of 1.2 W/m2.

Our triple glazed casement window achieves a whole window U Value (Uw) of 1.1 W/m2.K, with a centre pane value of 0.76 W/m2.

T&K work in partnership with Pilkington UK, and as so only use the market leader in sealed unit supply (glazing).

Toughened, anti-sharding glass is fitted where required (such as Bathrooms and Doors), in accordance with BSEN12150.
