Energy Efficiency

Warmth and Comfort and benefits enjoyed by homeowners because Alitherm windows are thermally efficient and contribute to a reduction in the cost of heating bills. Our windows have been designed to reduce heat loss by the use of a thermally broken aluminium frame with a polyamide bridge. The polyamide material has a very high resistance to heat transfer from the inner face of a frame (i.e. inside a room) to the external face of a frame (i.e. outside). The thermally broken frames provide homeowners with windows that have distinct advantages.
