Wooden windows

High Performance flush

Our HP flush window system is at the very cutting edge of window technology, being able to conform to all new build and refurbishment regulations using its two incorporated weather seals, sturdy 5 point espagnolette locking system and friction hinges. it can also achieve very low U-values by using a high performance 4-16-4 double glazed unit in the makeup of the sash.

High Performance conservation

The high performance conservation window takes many of the elements of our high performance flush window with its 2 weather seals, 4 point locking system and high performance double glazed unit, but it allows the customer to opt for more traditional butt hinges giving it the appearance of a window you may find in a listed property from the inside and out. 

Thin light conservation

The thin light conservation window gives the customer the best of both worlds in the terms of allowing them to install double glazing where it may not be possible with thicker double glazed units as at only 12 millimetres thick it can be installed into a 44 millimetre thick casement which is the thickness of the vast majority of old single glazed sashes, it lends itself very nicely as it can be manufactured with a full thickness 26 millimetre glazing bar which again is what you would find on many single glazed casements. it is very sympathetic to the aesthetics of older buildings while providing modern day insulated double glazing.

Bespoke ultra conservation

We are able to manufacture windows to any specification such as curved frames, single glazing or lesser used mouldings, we will match anything at a customers request.
