Our casements are designed with performance in mind. The air infiltration on our casement is often better than our competitors’ fixed windows. One of the most important features of a casement window is the operating mechanism, so we installed roto crank hardware with unbelievable leverage and power.
The Comfort Series 4300 Casement window has air infiltration ratings that are tighter than some of our competitors’ fixed windows! With twenty-one chambers of fusion-welded vinyl, this casement has uncommon strength, warmth and overall long-term performance characteristics.
Gerkin 5300 casement windows are designed with performance in mind. The air infiltration on our casement is often better than our competitors’ fixed windows.
