The alternative to PVCu double glazing
Secondary Double Glazing from Kent Blaxill provides an economic alternative suitable for period and listed properties where plastic replacement windows would destroy the character of the building. Living in a period property does not mean you have to put up with cold draughts and sky high fuel bills!
The units fit to the inside of existing windows and do not change the exterior look of the building.
Why choose Secondary Double Glazing?
_ Reduced heat loss
_ Reduced noise pollution
_ Reduced condensation
_ Elimination of cold draughts
_ Can be fitted to existing casement windows easily
_ Fitting & Surveying service available using our trained craftsmen
