One method that homeowners use to reduce heating and cooling bills, is to install energy efficient windows and doors. In regards to window insulation, there are many types of insulation available, and it is imperative for every homeowner to know about them, so that you can know how to make the right choice, when installing new windows or doing replacement work.
Below is a brief look into some of the window insulation types:
Tinting works by reducing the amount of heat absorbed, and the glare of the sun. Gray and bronze tinted windows will block both heat and light, while green and blue tints will block heat, and allow adequate light to pass through. Tints such as black on the other hand, will make rooms look darker, and so they are not recommended for window insulation within homes.
Double and triple glazed windows
These insulated window types are made of two or three panes of glass, with air trapped in between the panes. The panes are normally spaced a few millimeters apart, and are sealed properly to ensure that the trapped air doesn’t escape. Since air is a poor conductor of heat, these windows are very efficient in regulating the heat loss or heat gain in the house.
These refer to microscopically thin layers of metal or metal oxides, which are applied to some or all of the panes in the window. The coatings are very difficult to spot, but they may appear as green tint, when they are under the right lighting conditions, to make them visible. The low-emissivity coatings are more effective than the air or gas pockets in the glazed windows, and they can reduce the energy loss by up to 50%.
Reflective coatings are available in gold, bronze, and silver, amongst other colours, and they make the outside of the windows look like reflective mirrors. They are perfect for stopping the glare, and redirecting heat from the sun. But they also block large amounts of natural light, and this is not acceptable for many homeowners.
