Advances in glass technology has now allowed us to achieve an insulating effect to windows to challenge double glazing. A standard double glazed unit with 4mm glass on either side and a 12mm airspace (That’s 20mm Thick) will achieve a similar insulating result as a single panel of Smartglass that is 4mm thick! This means that your existing home can be insulated against the heat and cold without having to change your window frames! This is ideal for homes built in the early 1900’s through to late 80’s. You will be amazed at how simply changing the type of glass in your windows can enhance your lifestyle and improve your power bills.
