The Heritage

For those with a keen eye for detail, our Heritage sliding sash uPVC window is, arguably, the most authentic-looking uPVC sliding sash window available on the market.

Unlike most other uPVC windows, the Heritage is hand-built using mechanical joints to replicate the traditional mortise and tenon method of timber windows.

The Heritage comes, as standard, with an authentic-looking white woodgrain foil, but is available in any RAL colour.

Design and Installation Services


We are passionate about what we do. We will take the time to go through the ideal design specification to best suit your property and budget. We're not interested in sitting in your house for hours on end offering silly 'deals'.


All of our installers are directly employed by us and are paid a fixed salary. Unlike most other companies who use sub-contractors, our teams are given the time to ensure that your project is completed to the most exacting standards

Peace of Mind

All IBGs are NOT the same. As members of The Consumer Protection Association, our insurance backed guarantee covers 100% of the contract value. Many of our competitors offer IBGs covering as little as 25%. We are a Certass registered company.

Interested in Heritage sliding sash windows?

We design and install with lasting peace of mind. We’ll give you an honest quote without sitting in your house for hours on end. We don’t start off with one price, then dramatically halve it after a bogus call to a fictitious boss. We don’t believe in working that way. We never have and we never will.
