Casement windows swing open like a door to provide superior ventilation and easy operation. Suitable for numerous home styles, Casements shut tightly, providing a firm, lasting seal and one of the highest thermal performance ratings of any window style. Practical and beautiful, Casements are easy to combine with other Loewen window styles for a unique look.

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.
