Why is roofing insulation necessary?In: Home and Garden [Recategorize] |
[Edit] |
Because you are losing 25% of your heat through there! (un-doubleglaxed windows lose 10%, un-insulated cavity walls lose 35%) The current regulation is 10inches (250mm) although new builds are having 12inches put in.
Basically, it's to save you money and to save the environment. An uninsulated roof is such a waste of energy and resources. If you have it insulated, your home will heat up quicker and when the heating switches off the heat takes longer to dissipate too. It also makes the upstairs cooler in the summer as the heat from the sun on the rooftiles stays in the loft and doesnt pass through the insulation thus you can sleep better. It works both ways. Clever stuff.
