Perfektion Wood

Thermal break aluminium wood system for casement openings

EKU Perfektion Wood high-performance windows have slim and basic lines for a contemporary aesthetic that focuses on maximum brightness by minimizing the visible surface of the profile. The project behind this refined and minimal design does not overlook functionality but combines a refined quality in the insulating materials with the perfect functioning of the concealed accessories, integrated within the profile itself.

The result is a larger glazed area combined with high thermal and acoustic insulation that ensures unparalleled everyday comfort. Thanks to the internal cladding in precious solid wood, the fixture creates a warm and welcoming living environment whilst the aluminium on the outside ensures an almost total absence of maintenance despite the excellent resistance to atmospheric agents.
