Most of the loss of heat occurs: due to uninsulated windows and doors - 63%; through window panes - 15%; through ceilings and walls -15%
At the onset of cold weather, do not forget to glue the windows and, if possible, the balcony doors. Also it is necessary to investigate the sills for the presence of cracks beneath them, which also affects the loss of heat.
The main method for reducing heat consumption and the cost of heating in homes is the insulation of external walls.
