Ventilation Sashes KMD VS

Ventilation Sashes

KMD.VS is a thermally insulated aluminum system of ventilation sashes designed to provide natural air exchange in buildings with increased requirements for airtightness and energy efficiency.

The system features narrow pivot sashes with widths of 180 or 240 mm, enabling controlled ventilation without opening primary window or façade elements.

KMD.VS can be used as a standalone solution or integrated into KMD.78 and KMD.88 window and door systems, as well as into the KMD.F50M curtain wall system. This allows for unified ventilation solutions across different types of building envelopes.

The system is based on aluminum profiles with polyamide thermal breaks, ensuring dimensional stability and required thermal performance. EPDM gaskets provide airtightness and resistance to environmental impact.
