Loft insulation Loft insulation is needed to save heat energy and contain it within the building. It reduces heat because hot air is lighter than cool air therefore hot air rises. Therefore the hot air that rises will stay at the top. Meanwhile the air below begins to gain heat and in turn rises while the hot air above loses heat and falls. This cycle is called convection. Loft insulation acts like a blanket‚ helping prevent heat escaping through the roof. Insulating your home isn’t a one

Loft insulation is needed because in uninsulated homes the hot air particles rise through the roof causing heat loss ‚ on average 25 percent of the heat is lost through the roof due to uninsulated lofts. Insulating lofts is very effective as it reduces heating bills and helps towards energy costs.. In a house where there is no loft insulation installed it would cost £250 and would save £145 per year ‚ also save 730kg of co2 per year. Although if the loft is insulated but needs to be topped up to

from homes by conduction through the walls‚ floor‚ roof and windows. It is also transferred from homes by convection. For example‚ cold air can enter the house through gaps in doors and windows‚ and convection currents can transfer heat energy in the loft to the roof tiles. Heat energy also leaves the house by radiation through the walls‚ roof and windows. http://www.bbc.co.uk/schools/gcsebitesize/science/ocr_gateway_pre_2011/energy_home/1_keeping_homes_warm2.shtml Visited 28/01/13 All objects give

Loft Insulation Research Loft insulation is an effective way to save energy and money in a home. A well insulated house keeps warmth indoors and not letting heat escape. By insulating a loft it will help to heat the home more efficiently. Using less energy reduces carbon dioxide emissions (CO2): which is one of the biggest causes of climate change. Another advantage is that people will also save money on their bills too. [1] Glass fibre or other loft insulation materials are laid across the loft
