The Challenge
Why This Product Exists
Windows are the weakest thermal link in any building envelope. Standard aluminum windows conduct heat 1,000 times faster than insulated walls, creating cold spots, condensation, and energy waste. In hot climates, they become radiators of solar heat. The challenge is achieving the strength and slim profiles of aluminum while eliminating its thermal conductivity.

Common Questions
Frequently Asked Questions
A thermal break is an insulating polyamide strip (typically 25mm+) inserted between the interior and exterior aluminum profiles. This breaks the thermal bridge, reducing heat transfer by up to 60% and eliminating interior condensation.
Outward opening casement windows hinge on the side and open outward, maximizing interior space. Inward opening casement windows open inward, allowing easier cleaning from inside — preferred for high-rise applications. Both achieve identical performance ratings.
Casement windows accept double glazing (24-28mm) and triple glazing (36-44mm). Glass options include Low-E, laminated, tempered, acoustic, and smart privacy glass — all manufactured by Will Enterprise for a fully integrated solution.
Standard powder coating in any RAL color, wood-grain finishes (sublimation), anodized finishes (natural, bronze, black), and dual-color options (different colors inside and outside).
