Since 1995, we’ve been supplying a range of specialist products and services including triple glazed windows and doors, MVHR heat recovery ventilation and airtightness products.
21° is committed to low energy building to help reduce carbon emissions and cut heating bills. The most effective way of doing this is to focus on the building fabric, using high levels of continuous insulation, together with stringent airtightness and advanced ventilation strategies. This approach leads us to be strong proponents of the Passivhaus approach to low energy building, which can cut a building’s heating need by up to 90%, compared with typical uninsulated UK housing stock.
As well as reducing energy bills and CO2 emissions, low energy and Passivhaus homes and buildings can improve the quality of life for occupants. Constant warm and even temperatures, eradication of mould and condensation issues, and elimination of cold spots or draughts can really make our homes and buildings more comfortable and enjoyable places to be.
By developing expertise in Passivhaus products, 21° hopes to facilitate the construction of Passivhaus buildings in the UK and to promote current ‘best practice’ in low carbon construction.
We offer a wide range of products, including triple-glazed timber & alu-clad windows and doors advanced MVHR heat recovery ventilation, specialist airtightness & insulation products.
All of our products are thoroughly tested and quality assured.
