Ceiling insulation is known as a 'thermal material' and is the single most important insulation in your home. Without it, your home can't be energy efficient and it's most likely going to be uncomfortable and very expensive either to heat and to cool. Ceiling insulation is measured in terms of R-value. That is resistance to heat. So the higher the number, the better the ceiling insulation is.
We all know that heat rises, so when you are heating your home in the winter, the hottest part is actually against the ceiling and that actually maximises the heat escaping through that ceiling.
In fact, a standard ceiling without insulation has an r-value of just 0. That is not very much at all and so the heat will travel readily through that. In summer time the temperature in your roof space can be as hot as a sauna and that heat will readily push through the ceiling into your home greatly increasing the cost of cooling.
So insulating your ceiling properly will make your home more comfortable to live in, much cheaper to operate and it will be good for the environment too. Insulation should be installed in ceilings with unheated spaces, floors above vented crawl spaces, cathedral ceilings and floors over unheated garages or porches.
Ceiling insulation usually involving the use of :. Glass wool originally known also as fiberglass is an insulating material made from fibres of glass arranged using a binder into a texture similar to wool.
