Casement Windows

Energy Efficiency, Security & Value – All Standard

Our high-performance PVC casement windows are designed with your home’s comfort and safety in mind. Every window comes with: A multi-chamber profile for superior insulation, FULL thermal reinforcement, energy-coated glass for maximum efficiency

Many local manufacturers offer double glazing with U-values of 1.4 or 1.3, we go further: 1.2 U-value for double glazing and 0.8 U-value for triple glazing. This means lower heat loss and a warmer, more energy-efficient home. 👉 Curious about the differences? Read about Double vs. Triple Glazing

Our windows are available in a wide variety of colours — including realistic woodgrain finishes — so you can find the perfect match for your home’s style.
