All of our casements feature a specially designed weather stripping system that seals tight and secure to keep out heat and cold. We combine this with heavy-duty operating hardware that makes opening (a full 90º for easy cleaning) and closing a breeze. Semco's extruded aluminum exterior casements are virtually maintenance-free and never need painting. They come in seven standard colors and your choice of three decorator colors.

Semco casements are available assembled into your choice of 30°, 45°, or 90° angle bays.

Simplicity is a thing of beauty. Windsor casements and awnings provide convenience and energy conservation in one easy-to-use, even easier-to-look-at unit. The Pinnacle casements and awnings offer maximum light, excellent ventilation and simple cleaning. With an endless number of sizes and options, we can make a casement or awning for any room in your home. We use a thick, two-inch sash and our special tape and silicone glazing method to increase insulation and, more importantly, reduce your energy bills. Our sleek, single-lever, multi-point hardware makes for effortless operation and a tight, leakproof fit.
