Triple Glazing

Offering maximum energy savings…

First developed in Norway and Demark, Triple Glazing was created to provide homes with effective insulation in even the most freezing of temperatures. Once considered expensive and something of a luxury, Triple Glazed Windows are becoming increasingly popular with homeowners thanks to their incredible energy efficiency and the continued drop in triple glazing prices.

Easily fitted to any style of window, Triple Glazing looks very similar to traditional double glazing; the one simple difference being there are three panes of glass instead of two. As with double glazing, the individual panes of Triple Glazed glass are separated by a vacuum. This vacuum, created using a special gas, serves to prevent heat from passing from the home. This third pane of glass makes a huge difference in terms of both outside noise reduction and heat insulation; with Triple Glazing Windows approximately 60% more heat efficient than standard ‘C’ rated double glazed windows.

Take your pick of a textured woodgrain or smooth surface effect…

We believe that you can never have too much choice. TradeMark can supply your new sash windows in just about colour you want, including several time-old favourites such as White, Cream and Black. If they’re a bit too old-school for your liking, you might like the charm of Chartwell Green or our modern Grey Blue woodgrain.
