One of the essential factors that makes a home truly a home is the convenience and comfort it provides us. As a result, we usually have a long to do list comprising things that come together to make sure our home is comfortable with ambient temperature at the very top of the scale of preference. After all, no matter how greatly designed your furniture and home decor is, it probably would amount for nothing if the temperature is either too hot or too cold. Some of the most common ways we incorporate to make the temperature a lot more conducive and warm during the winter months is by installing air conditioning system or through top notch insulation materials, but the fact still remains that a lot of heat would escape through the doors and windows. And that’s exactly the use of double glazing. So how exactly does double glazing work?
Double glazing basically works by preventing the escape of air and trapping it between two panes of glass. It’s the trapped air which serves as an insulation barrier which delivers 3 major functions. First and foremost, it stops the escape of heat through the window as the barrier created insulates the room from varying air temperatures at both sides of the glazing unit. The second major function is the double glazing works to keep down noise pollution coming from outside. While the third major function of double glazing I the fact that it helps minimize condensation which usually occurs on the single glazed windows’ inside as the cold outside air works to cool the warm air inside the house. When you install a double glazing window, the insulation barrier generated will work to stop the air temperature transmission which ultimately helps prevent the occurrence of condensation.
Most installers will not need you to be at home while they are fitting your windows. It is a good idea to be present though, just in case they have any questions for you and perhaps for your own peace of mind. If you cannot be there, you will need to arrange access to the property and/or agree securing the property at the end of the day.
Using a Fensa registered installer isn’t compulsory but it helps to protect you from cowboys and rogue traders. It will also make life a whole lot easier in regards to Building Regulations. Replacement windows must meet a certain energy efficiency rating and once fitted you need a certificate to show your installation complies. By using a Fensa registered company they’ll issue this certificate, otherwise you’ll need the council to look at the new windows.
On the grand scale of things there isn’t a huge difference between B-rated windows and A-rated windows. Consumer watchdog Which? have calculated an extra 6.5% would be saved on energy bills with A rather than B rated panes. Be aware that A rated windows are slightly more expensive, however.
