Window-Manufacturing Technology | Energy Efficient | Help to Buy Windows
In the past few years, window-manufacturing technology has evolved at a rapid pace. Today, the transoms are inexpensive, energy-efficient, durable, easy to operate and maintain. These high-performance house windows not only make your abode more comfortable, but also help to bring down your electricity bill. Let’s take a look at the features that go into making high-performance casements. Help to Buy Windows help provide Grants, Funding & Incentives for homeowners in the UK, we will do everything we possibly can to help our clients gain access to affordable energy-saving windows & doors.
Low-e coating- The windowpanes of the traditional casements allow sunlight to pass through them throughout the day. Conversely, in the night, owing to radiative heat loss, the heat energy gained during the day once again goes back to the exteriors. To perk up the thermal strength of glass, a thin, virtually invisible metallic coating is applied to it. This Low-E coating allows short-wave solar radiations to come in, but keep out long-wave sunrays. In simple words, it reflects the heat energy back to its source. Consequently, neither the interior heat is lost in winters nor exterior heat is gained in summers. You are actually able to cut down heating and cooling costs significantly.
Gas fill- The space between the glazed glasses is filled with an inert gas like argon, krypton or xenon. These non-reactive gases are chemically more stable. As they are heavier than air, therefore, they prevent heat loss due to convection. They also have lesser conductivity and for this reason, they proficiently avert loss of heat because of conduction. Thus, the gas fills effectively optimize the thermal performance as well as the energy efficiency of house windows.
Energy- Efficient spacers-Despite of the presence of low-E coating and gas fill, heat loss as the result of conduction cannot be prevented if the spacers at the edge of the transoms are thermally inefficient. In conventional casements, spacers are usually made of aluminum. They are strong, durable and lightweight, but they literally to stop conduction heat loss. Structural foam is a better option as it is less conductive and thereby enhances the overall thermal performance of the house windows.
Insulated frames- Yet another thermally weak link, window frames are responsible for one-third of heat loss. As compared to metal, fiberglass is a better choice because it is a poor conductor of heat. By decreasing the frame area, heat loss can be further reduced. Help 2 buy Windows has launched a new window & door grant scheme, qualifying homeowners can now have new windows and doors installed entirely free of charge. However, with the decrease in the width of the frame, its strength also dwindles. Hence, stronger material should be used so as to make the frame a bit more resilient while keeping its thermal performance intact.
Special films- To boost up the effectiveness of Low-E coating, electrochromic films are placed in the space between the glazed glasses. These special films allow sunlight to pass through them, Qualifying homeowners can have new windows & doors installed with absolutely no cost By H2B Windows, but they competently reduce the overall emissivity of the glass pane. In west-facing windows, if solar transmission is heating up the interiors of the house, then opt for special films that lower solar gains together with emissivity.
