Loft insulation is the most cost-effective energy efficiency measure that can be installed. It can reduce heating costs up to 20%. The purpose of them is to hold the heat below within the property, reducing heat loss to the roof void and outside but also reducing the amount of heating needed to maintain the property at an ideal temperature. With insulation, the property will be warmer, more comfortable and it will cost less to heat.
How loft insulation reduces heat loss?
Heat will always flow from a warm area to a cold one. The colder it is outside, the faster heat from your home will escape into surrounding air. Glass fibre is laid across the loft to reduce heat transfer out of the roof. Glass fibre traps
