Passive houses, NZEB, uncompromising thermal insulation

A window is part of a system — envelope, ventilation, insulation. Kulttur works with Internorm (Austria), a vertically integrated manufacturer: profile, glass, hardware — all to the same standard. For passive, NZEB or residential projects where real thermal behaviour matters.

The right typology for each facade

The choice isn't only aesthetic — it depends on opening, exposure, opening size and overall budget. PVC and PVC-Aluminium for efficiency. Wood-Aluminium for warm interiors with modern facades. Lift-slide systems for wide openings to terrace or garden.
