For a start, a house loses a lot of heat through the windows. Most people think covering the windows with curtains is a solution to this. The truth of the matter is curtains do little to contain the heat in your house. There are better ways to conserve the heat in a room. Double glazing the windows is more efficient method of heat conservation. If you have the adequate funds you can triple glaze your windows. Research shows that a residence can cut up to 18% of its energy usage by double glazing the windows. With such an amount of energy savings, the cost of double glazing the windows is nothing but a drop in the ocean.

The following are the benefits you reap by double glazing your windows;

Heat is retained

Double glazing the windows retains heat within the building. Double glazing reduces draughts. He result of this is reduced rate of heat loss. Double glazing should not only focus on the glass panes but also the casing. Other factors such as the climatic conditions and the indoor temperature will play their role. A good window allows more heat into a room and reduces the travel of heat in the opposite direction. A single glazed window does little heat retention.

Energy conservation

A report by the energy Saving Trust revealed that double glazed windows make annual energy savings of up to £170. The life span of a double glazed window is two decades. The savings over that period of time translate to £3,400. Before purchasing windows, always check the energy rating of the window. The rating determines how good the window will conserve energy. The British Fenestration Rating Council (BFRC) determines the energy rating after rigorous experimenting. The energy rating is a letter between A and E. the rating is also a reflection of other qualities such as the ability to resist condensation as well as keep out wind and sound insulation capacity of the window. Fitting double glazed windows should be seen as a long-term investment since it is expensive.

Sound insulation

Any double glazed window manufactured after the year 2002 and is labeled energy efficient has the added advantage of sound insulation. Sound insulation means that the window will keep out the noise and prevent interior sound from going out. Sound proofing can be a great advantage if your house is located near an industrial area, a school or a busy road.
