Ceiling Insulation and Types of Ceilings

Insulation

The ceiling is one of the primary areas that require heat insulation as this is the area that heat will rise to and in the case of a ceiling under a roof rather than a floor also where heat gain from the sun and therefore into the roof space, an area that will allow heat to enter the habitable space.

Quite undesirable in the middle of summer or if an air conditioning system is at work. There are a number of methods to use when insulating, the most common of which is fiberglass wool blanket or bales spread out over the ceiling to create an insulating barrier.

It does this by creating an air barrier in the insulation stopping or reducing heat transference.

Heat will naturally rise or "gravitate" and disperse to the cold area. There are other systems that use granulated and treated paper and items such as expanded vermiculite.

However the main point is that the majority of systems reduce heat transference by creating an air barrier.
