Casement Windows

CA5500 Casement Window System – Built for Superior Performance

RetroTeck Window Mfg. Ltd. casement windows come in a wide range of sizes, all with reinforced stiles for additional strength to anchor hinges. A triple-bulb seal for a tighter window helps keep water and air out. You can choose from the cam handle (standard) and the multi-lock roto hardware (optional). We are pleased to offer various muntin bar options in a wide range of grids and custom shapes per request.

We Eliminate Water & Air Leakage

As with our sliding window system, single hung windows and awning window system, our casement windows have a 100% fusion-welded vinyl frame with sash corners for added strength and durability. Water and air leakage is eliminated at critical corner locations. Our windows provide outstanding benefit to you as the 100% vinyl construction offers immediate savings in reduced energy bills. Our energy-efficient models not only guard against temperature extremes, but also provide an effective noise barrier.
