Casement windows (also called side-hung) are the most common window type and offer the best insulation performance. They open by rotating on side hinges, allowing 100% ventilation of the opening. They are the default choice when space is not restricted.
The casement window is the opening system with the best insulation-to-price ratio. When closed, the sash presses against the frame with perimeter weatherseals, creating an airtight closure superior to any other opening type.
5 or 6-chamber PVC profiles, combined with double or triple glazing, achieve thermal transmittance values (Uf) as low as 0.8 W/m²K — enough to meet the most demanding PassivHaus standards.
