Double Casement Window
Two openable sashes with a central mullion.
Airtight, soundproof uPVC casement windows — openable, fixed, top-hung, combination and tilt & turn designs.
The 60 Casement Series is a precision-engineered uPVC window system for homes and commercial buildings. Casement sashes are hinged and close firmly against continuous EPDM gaskets with multi-point locking, giving the best protection against noise, dust, wind and driving rain.
Because the sash opens fully, casement windows deliver excellent ventilation. Combine openable, fixed and top-hung sections into a single frame to create the perfect window for every room — from large living-room windows to compact bathroom ventilators.

Compression seals make casement the quietest window type.
Continuous gaskets and multi-point locks resist driving rain.
Sashes open fully for maximum fresh air.
Reduces heat gain so rooms stay cooler and AC costs drop.
Locks engage at several points along the sash.
Mix openable, fixed and vent sections in any layout.
Every unit is fabricated to your exact opening size, glass choice and finish.
