Choosing Energy Efficient Windows

There are very many homes still in the UK that have older less energy efficient windows fitted. Therefore it will be a lot more sensible to fit new, more efficient units and bring your home into the 21st century. The new, energy-efficient type of windows will, in time pay for themselves through low heating and cooling costs, and maybe even the cost of lighting your home. Provided these are sensibly selected and fitted, energy-efficient windows will help to reduce those heating, cooling, and lighting costs. London Glazing can advise on this. Improving window performance in your home involves design, selection, and installation. Before choosing the new windows for your house, work out what types of windows will work the best and how to maximise your home’s energy saving. You should understand the energy performance ratings of windows so you will know what energy performance ratings you need for your windows based on your climate and the design of the house. For the energy-efficient windows, ENERGY STAR® has created minimum energy performance ratings by climate. London Glaziers are experts in glass. These criteria, however don’t account for a home’s design, such as the window positions. These passive type of solar design plans use the glass to maximize solar heat gain in winter and minimize it in summer. In climates that are dominated by heat, major glazing areas should generally face south to collect solar heat during the winter when the sun is low in the sky. In the summer, when the sun is high overhead, overhangs or other shading devices prevent excessive heat gain. Windows on east, west, and north-facing walls should be few while still allowing for adequate daylight. It is difficult to control heat and light through east and west facing windows when the sun is low in the sky, and these windows should have a low SHGC. (solar heat gain coefficient).
