Thermeco's aluminium casement windows are windows which are side hung on hinges to allow the maximum circulation of fresh air.
The openings can be restricted for safety.
Casements are available in single and two-wing configurations. The use of an openable mullion for two-wing configurations gives 100% unobstructed views.
Thermeco aluminium casements feature European technology multi-point locks for added security and excellent weather sealing.
We have a large range, with different frame types, widths and energy efficiencies available.  Available inward or outward
