STANDARD WINDOWS.
From the outside, an aluminium window; from the inside, a thermal insulation window; in profile, a revolution.
The complex structure shows how there is no possibility of heat loss in the AL3: this is because we have done everything to prevent unwanted air circulation and thermal bridges. Sophisticated seals, optimised insulation webs, and the highest degree of precision fitting minimise temperature exchange. Our innovative aluminium window thus keeps the cold out in winter and blocks the heat in summer.
