About thermal windows

Ever felt the chill in winter despite the heater, or noticed your home heat up quickly in summer once the AC is off? Thermally broken windows are the answer. With a polyamide strip inside the aluminium frame, they block heat and cold from passing through, keeping your space perfectly comfortable, no matter the season.

Absolutely. Thermally broken windows reduce heat transfer, keeping your home cool even in intense summer heat. Untreated frames allow over 85% of external heat inside, while thermally broken aluminium keeps interiors cooler, cutting down on air conditioning. Standard frames can reach up to 70°C in the sun, but treated aluminium offers insulation, UV protection, and salt resistance for lasting performance.
