Anywhere in the house, where there are thermal differences, expensively generated heat is released through the constructional elements. Well-done insulation not only protects your wallet, but also the environment.
There is a variety of effective measures. Starting with some free "rules" such as "correct ventilation, heating properly and correct funishing" up to expensive projects such as facade, roof / attic insulation, replace windows or optimize the heating system.
During renovation, often surfaces are released which usually are not accessible. In particular radiator niches, interior walls, ceilings, window reveals and roller shutters. Also the areas under laminate flooring or even exposed heating pipes in unheated basements. In all these places CLIMAPOR® insulation products help reducing energy loss.
