Double Glazing versus Triple Glazing
So if you are going to the trouble and expense of replacing your windows and doors, shouldn't you reduce your energy bills even further by getting triple glazed windows? Well not necessarily for research by the Energy Saving Trust showed no difference in terms of energy efficiency. The way double glazing works is to create an insulating barrier between two sheets of glass. High quality glazing should therefore provide a high level of energy efficiency which would make little difference if the glass were triple glazed.
