Loft
insulation acts like a blanket, trapping any heat rising from the house
and not allowing the heat to get through your roof during the hot
summer days to keep your home cooler.
If your attic is already insulated, it pays to make sure you have enough insulation to achieve maximum savings. The UK Energy Saving Trust says that if every installed 270mm loft insulation, we could save almost £ 500 million - and 2.7 million tons of carbon dioxide per year, the equivalent of taking almost 100,000 cars off the road.
Loft insulation is at least 40 years, and it will pay off for you over and over again at this time. But if you live in the UK, you can use the insulation done for free by the government funding.
Let us now look at the materials used for the roof insulation, recommended by the Energy Saving Trust.
Matting - sometimes as a blanket or blanket insulation - sold as a flexible rolls of different thicknesses. The most common type is mineral wool, made of glass or rock wool. This is the standard material for the isolation of an empty attic, and is commonly used in stud walls and insulation under suspended wooden floors. Other materials such as sheep's wool are also available. You should wear a protective mask and gloves when working with mineral wool.
Escape - Stuffed cork granules, vermiculite, mineral wool or cellulose fiber is sold in bags. It is usually poured between the joists to insulate lofts. Because it is so flexible, it is ideal for lofts with difficult corners or obstacles, or if the bar spacing is irregular or not the same size as the mats are available.
Blown insulation of refractory cellulosic fiber made from recycled newspapers or mineral wool. It should only professionals who use special equipment to the loose material in a certain, will be installed in cut off area to blow the required depth. The material can be relaxed when used for roof insulation, but can also bind to a surface (and yourself) to isolate stud walls etc.
Rigid insulating panels can be used to insulate walls, floors and ceilings. They are usually made of foamed plastic such as polystyrene, polyurethane (PUR) or polyisocyanurate (PIR). PUR and PIR board are among the best insulating materials commonly used and so are useful where space is limited. Rigid board has to be cut to size, is often a suitable qualified activity.
You can have as much insulation you want, as long as it provided space in your attic. You lose the thicker the insulation, the less heat, and the more money you save. However, some materials are better than others, so thin layers of some materials get the same performance as thicker layers of other materials to get.
If you live in the UK, you can make your attic insulated with mineral wool insulation grants through the roof for all homeowners and private tenants....
