Double Glazing

One of the greatest advancements in window energy efficiency is the introduction of Double Glazing.
The major benefits are that our windows can be manufactured to match the original style and mouldings but they will incorporate the latest in energy-efficient technology and create a more comfortable, warmer and quieter environment.
Double Glazing incorporates 4mm Toughened Low E Glass and a 4mm Soft Coat (energy efficient) Inner Pane which is not only a subtle transformation but is aesthetically pleasing and in keeping with the traditional style of timber windows.
Despite being such simple improvements, the real-life benefits of effective draught-proofing windows and double glazing all translate into enormous savings on energy bills – some researchers stating as much as a 25% decrease, just by draught-proofing alone. With a new traditional manufactured timber windows being a relatively small expense to replace, the ongoing savings are reached sooner whilst enjoying a more comfortable home.
