The 20mm gap between the panes of glass help keep the heat in and sound out, whilst a low-e coating on the inner pane reflects heat back into your home.
When the glazing unit is combined with our multi-chambered, draught-proofed frame, the result is a state-of-the-art window that will help to keep your home warmer, lower your bills and care for the environment.
