Because Sheerframe PVC windows and doors can be provided with exceptional weather tightness and energy performance using specialist glazing and construction methods, they can be central towards the achievement of a zero carbon home which requires a category six under the energy element in the Code for Sustainable Homes.
Sheerframe windows, for example, can achieve an 'A' rating under the DWER calculation system (Domestic Window Energy Rating), incorporating enhanced thermal features such as Thermlock reinforcement, exceptional weather tightness and several separated structural chambers within the profiles giving improved thermal efficiency.
The Sheerframe HED (Homogenous Energy Dynamics) system creates stronger, lighter and significantly more thermally efficient windows, offering housebuilders a simple and cost effective route to achieving window U-values of just 0.8W/m2K in their drive towards viable zero carbon homes. Such a low U value is equivalent to the rating required for Category 5 and 6 star rated dwellings in the Code for Sustainable Homes.
