GARANT
THERMAL INSULATION
Reduce heating costs
Save energy through thermal protection
Do you have excessive heating costs? Most often, it is not your heating that is at issue, but your windows.
“They will last a few more years” is what every householder thinks when looking at their old windows. If the window still looks good from the outside, it still does not mean that it has good enough thermal insulation. How much money is literally thrown through poorly insulated windows is not entirely clear to most people. If we postpone window replacement for a long time, we are certainly saving on the wrong side.
With GARANT windows, you save money and at the same time contribute to environmental protection!
On average, about 8% of the surface of the building envelope is made up of windows, but they cause almost 40% of heat losses.
The thermal camera shows without a doubt: Before rehabilitation with GARANT windows, high temperatures on the surface and thus significant energy losses in the area of the frame and glass – clearly recognizable surfaces in red and yellow. After replacing the windows, the energy loss was completely minimized.
