Double Glazing Window Energy Ratings Regardless if you are considering replacing your windows and doors, or building a new conservatory, energy saving should be at the forefront of all your renovation plans. All new installations should, however, match existing ones; the same holds true for the conservatory walls that should blend in with the windows in the rest of the house. Depending on the type of area or building you live in, companies offering double glazing in Lanarkshire can help you with any approvals that may be required.
Energy efficiency Thermal insulation can be achieved with double glazing windows, doors or walls made of Low E, or low-emissivity glass. This type of glass is very energy efficient, which is measured by its U value and its Solar Heat Gain Coefficient (SHGC). Thus, the lower the U value, the more efficient the insulation against heat loss, whereas the higher the SHGC, the greater the window’s energy efficiency will be. The SHGC, also known as the g-value, or the solar factor, shows the ability of a thermal insulation glass to let solar heat into a room. Usually, thermal insulation glass can be combined with other double glazing window solutions to make it more decorative or to enhance its energy ratings, such as acoustic, solar control, or self-cleaning glass. Moreover, particularly in the case of conservatories, security frames and glass should be used for enhanced protection against intrusion; to the same end, any glass used should be toughened or laminated. Bear in mind that the thicker the material, the stronger the glass wall will be.
