About the Specialist Timber Windows product range

Here at Specialist Timber Windows we supply high quality timber fenestration products designed and manufactured by the pioneers of energy efficient housing in Europe. With our two leading ranges we hope to drive the UK out of the uPVC stone age, following the Austrians and many others in a search for supreme quality, energy efficient and environmentally friendly double glazed timber windows.

We are actively required to meet ultra low u-values for low energy houses and meet planning regulations in listed buildings while consistently improving energy efficiency. We can achieve this due to our timber frames, high spec glazing and professional installation.

The Specialist Timber Window Company has fast become recognised as a one-stop shop for the Architect, Homebuilder and Homeowner as a key supplier for all their fenestration needs. Whilst we are based in the Oxfordshire region and close to Swindon in Wiltshire, we operate on a national level and are proud to be the UK distribution partner for Katzbeck in the South of the UK.
