Product description

Slim Line 38 is a highly insulated aluminium window that is suitable for inward and outward opening, which combines elegance and comfort, with a unique design. This special slender steel look is the perfect window for modern architecture and renovation of steel-frames, respecting the original design but offering a thermally improved solution.

The SL 38 window is available in 3 different minimalistic design variants, Classic, Ferro and Cubic, to perfectly match the architectural aspect of the building. The windows and doors can be provided with double and triple glazing without losing the ultra-slim look.

In combination with its superior insulation capabilities, the system provides the perfect harmony between durable material, clean design and demanding architectural challenges.
