New showroom

Timber Windows Norfolk is able to offer Heritage Conservation Glass- Double Glazed Sealed Units, for replacing old single glazed units in Conservation Areas, and Listed Buildings.


These new glass units significantly improve the overall Thermal Performance of old windows, whilst keeping the traditional appearance and sight lines of the old singled glazed units. There are a range of Glazing Beads that compliment the existing window profile.


TWN along with their supply-chain partners, are now supplying Passive Windows. The preferred Install Sub-Contractors, Alopex, have installed to Passive Standards on a number of projects across the UK. Pictures and further information on these projects will be updated to the Projects Page.
