We also offer secondary glazing to improve the thermal efficiency of existing windows and internal window shutters!

All our windows are designed to improve the energy efficiency of your home, and our window styles feature advanced profiles and high-performance glazing. We offer double glazing and triple glazing options, with many of our windows achieving impressive U-values. This helps to keep your home comfortable all year round, reduce energy bills and helps make your home kinder to the environment!
Do you offer a guarantee for replacement windows?
Yes - all our windows come with a comprehensive 10-year insurance-backed guarantee, demonstrating our confidence in their quality and performance.
Where do you install windows?
We install throughout Essex and Suffolk, including Colchester, Chelmsford, Ipswich, Braintree, Sudbury, and surrounding areas. Our range includes a range of styles that are suitable for both traditional homes and modern homes.
What type of window is most energy-efficient?
The most energy-efficient windows use multiple glazing layers, low-emissivity glass, and inert gas fills such as argon between the panes. uPVC and aluminium frames with thermal breaks further reduce heat loss. Casement and tilt-and-turn styles often achieve top energy ratings due to their tight seals and insulated frames.
Do energy-efficient windows really work?
Yes. Energy-efficient windows reduce heat loss and help maintain a consistent indoor temperature, cutting the energy needed for heating or cooling. They also reduce draughts, prevent condensation, and make homes quieter and more comfortable year-round.
