Energy Efficient Windows

Many home and business owners are motivated to install energy efficient windows because of the environmental benefits they offer; but along with these environmental benefits, these types of windows are also cost saving. Today’s new construction projects almost always involve the installation of energy efficient windows, but even in an older building the savings afforded by these kinds of windows will often justify their installation. So what are energy efficient windows and what are their benefits?How they WorkObviously, the purpose of heating and cooling your home or business is to control internal temperatures. In the summer, you want to keep the hot air out and the cold air in, and the opposite in winter. Windows are an important barrier to heat exchange, but traditional windows that are constructed from glass and metal are actually excellent materials for heat transfer. This can lead to a lot of energy loss.Conversely, air is not a very good conductor of heat. Energy efficient windows therefore take advantage of this property; they are constructed with a layer of air between two sheets of glass. Sometimes known as double-glazed or double-paned windows, energy efficient varieties slow heat transfer simply because of the presence of air. As window technology has advanced, newer eco-windows feature a non-toxic, colourless gas that is even better at resisting heat transfer. In addition, the newest energy efficient windows are coated with a very thin film that mirrors sunlight to also prevent heat transfer. Finally, the most efficient types are no longer designed with metal frames. Instead, the frames are insulated and made from non-metal or hybrid materials to improve insulation.BenefitsThe benefits of these types of windoes are various. From lower energy and heating costs to reduced fading of carpets and upholstery, efficient windows make a great choice for any home or office.Energy and cost saving – Energy efficient windows have been shown to significantly the costs associated with heating and cooling. In fact, in just a few years, these windows will typically pay for themselves.
Reduced HVAC costs – In addition to reduced heating and cooling costs, high-performance windows also reduce peak heating and cooling loads (the maximum requirement for heating or cooling at any given time). This means there is less stress on your HVAC system, and you can often install a smaller or more efficient HVAC system.
Better comfort – High performance windows prevent windows from getting cold inside and also significantly reduce drafts. In addition, by reflecting sunlight, these windows can prevent the discomfort associated with overheating.
Eliminate condensation – Traditional windows often develop condensation when warmer indoor temperatures contact cool outdoor temperatures at your windows. Because they prevent heat transfer, energy efficient windows are warmer on interior surfaces and reduce frost and condensation.
Prevent fading – Finally, as already discussed, energy efficient windows are usually coated with a thin, clear film that reflects sunlight. This prevents sunlight from entering through windows and fading carpet, fabrics, art, and upholstery.
