  • Easy to Operate

    Casement windows are designed for straightforward everyday operation, with accessible handles and opening mechanisms.

    Modern casement windows can be combined with high-performance double glazing to help reduce heat loss and improve comfort throughout your home.

  • Secure by Design

    Strong frames, quality hardware and modern glazing options can provide improved home security when specified as part of a complete window system.

  • Low Maintenance

    uPVC and aluminium casement windows are designed to stay looking great with minimal upkeep, helping you enjoy attractive, long-lasting windows without the regular painting or staining required by traditional timber frames.

High-Performance Glazing for Casement Windows

The right glazing can make a significant difference to the comfort and performance of your windows. Our casement windows come with high-performance double glazing as standard, with additional options available depending on your needs.

Choose specialist glazing designed to improve energy efficiency, reduce outside noise, protect interiors from harmful UV rays or provide enhanced security. Our ClimaPane, ArmourPane and UltraPane systems are designed around different performance requirements.

Thermal Performance

Warm-edge spacer bars, gas-filled cavities and soft-coated glass help improve thermal efficiency.

UV Protection

Specialist glass can help reduce UV exposure and protect furnishings from fading.

Sound Reduction

ArmourPane glass can provide enhanced acoustic performance for homes affected by outside noise.

From start to finish everything was perfect. Simon Mumberson was our salesman and he fantastic a really great guy. We got 6 windows and 3 doors and a roller garage door fitted and everything went perfectly and looks great.

We are so pleased with our new roof fitted by Keswick Superglaze. With practical and experienced advice from Craig and Simon we decided on a solid warm roof with two large glass panels. All in all, money well spent!
