The Esterno white fixed window is a fixed PVC window.

At Solid, we focus on maximum insulation and energy efficiency. That is why we use high-performance glass with a Ug value of 1.1 W/(m²·K), based on a 4/16/4 glass configuration. To qualify for renovation grants, the Ug value of the glass may not exceed 1.1 W/(m²·K).

Our window profiles feature five thermally insulating chambers, resulting in an excellent Uw value of 1.3 W/(m²·K) for the complete window. The galvanized steel reinforcement in the core ensures additional stability and long-lasting durability, even under intensive use.

• Profile: 71 mm

• 1 mm frame reinforcement

• Glazing: 4/16/4 mm (glass thickness / cavity / glass thickness)

• Ug (glass insulation value) = 1.1 W/m²K

• Uw (window insulation value) = 1.3 W/m²K
