Manufactured in reflection of modern standards, our sliding sash windows offer impressive standards of thermal efficiency. Their high performance profile works to increase the heat retention of your home, achieving an ‘A’ energy rating with 24mm sealed units. This ensures your home remains warm and comfortable throughout the year.

Increased heat retention not only allows your home to get warmer and stay warmer for a longer period of time, it also allows you to see a reduction in your heating costs. As the performance of your central heating will be improved, you will rely on it much less heavily throughout the year. This will also allow you to reduce your carbon footprint simultaneously.

To prevent draughts, we install pile seals to both the sash and outerframes. Draughts can be extremely detrimental to home comfort, and are well associated with outdated or inferior window designs. Our Approved Installers are well versed in professionally installing our sliding sash windows, meaning performance is guaranteed.
