How to reduce heat loss through the WINDOWS even more?
You are recommended to use the SUPERthermo pane (U=0.5 W/m 2K PN-EN 674:1999) with your windows. Further decrease in the window thermal conductivity coefficient (U-value) amounting to 5-15% will be brought by installing external roller shutters. Another important issue is proper mounting of the window into the wall to ensure the reduction of heat leakage bridges and large heat loss where the wall and frame meet.
