Thermally Efficient Sliding Sash Windows
One significant benefit of our uPVC sliding sash windows is their energy efficiency. You can enjoy the period aesthetics of vertical sliding windows, with all the heat retention of a casement or tilt and turn frame. Our sliding sash profiles are multi chambered, and we use double glazed units as standard, providing a low U-value of just 1.49 W/m2K.
Approved Sash Window Installers
Renovating an older property can be daunting. For that reason, we only allow the very best local installers to fit our sliding sash windows. This allows you to place your complete trust in our services, having peace of mind that your home will be treated with the utmost care.
Secure, Durable Sliding Sash Windows
Another drawback of sticking with old, timber sash windows is their lack of security. Feeling comfortable in your home is a must nowadays, so we incorporate a number of safety features into our sash windows. This includes an anti jemmy bar.
By upgrading to uPVC, you’ll significantly lower the upkeep requirement of your double glazing. Our modern sliding sash windows are manufactured to be weatherproof and long lasting, while only needing occasional maintenance to perform their best. That means less time cleaning, more time doing what you’d prefer.
