We are specialists in restoration and refurbishment and best conservation practise. Using traditional methods, we subtly introduce some modern techniques to improve performance such as our Timeless draught proofing system installed in discrete locations. In some cases the introduction of slimline double glazing may be allowed. Here at Timeless we have developed a unique system that allows very fine historic glazing bars to take a slimline double glazed unit. We can double glaze a glazing bar as slim as 16mm in width.
