When it comes to glass there are multiple options to give you the choices you need, including double and triple glazing, solar control and obscure glass.
Glass offers the highest insulation element on a window so the many options available can really help keep the warm in and keep the cold out plus options to prevent overheating.
Although we supply both and will work with either, we are firm believers in the benefits of triple glazing. It does provide superior performance and greater comfort in the home. It is true that it does marginally reduce light levels, however this can also help to reduce overheating. For more information on this see
