Windows represent the main source of energy loss in houses and, according to the size and the material used to realize them, they can contribute up to 50% of energy waste.
Substituting old windows with new insulating PVC frames can represent the winning solution to avoid such a loss and contribute to energy saving, that is to say to money saving; as a matter of fact, the insulating properties of the new frames can shortly abate heating expenses in winter and air conditioning ones in summer, and in a few years the energy saving achieved can totally refund the expenses for the substitution of old frames.
The Cuccu frames enjoy the 55% tax credits provided for by the financial law for the requalification of the building stock (see the related regulations to the Financial law 2006 DLGS 192/05, anticrisis D.L. 29.11.2008 nr. 185)
