The openings

Even the non-professionals are certainly clear about the need to live in domestic environments well lit by natural light and with a good air exchange.

The openings that make external contact with the inside of the building are a very important point.

The exchange of air and light and in part heat is in fact regulated according to the quality, size and correct installation of doors and windows.

Light influences mood and metabolism and illuminates environments.

There must be a regular but not annoying exchange of air that makes the interiors more livable.

If the frames have not been laid carefully, they can create thermal bridges and annoying drafts which, besides annoying, will increase the building management costs and generate pollution.
