How does insulation work

 Insulation is used to keep the heat inside of your home for as long as possible,as well as keeping your bills down.

Insulation is available in a few different material types.
 .fibreglass
.foam
.cellulose

Insulation can be used in lots of places through out a home but is most commonly used for walls and lofts as these are the most common areas of heat lose.

Insulation is designed to stop heat from passing through it by creating a resistance so that hot air cant pass through it easily trapping the hot air inside your home for longer.

Insulation resistance is normally measured in 'R'.The higher the R value the more resistance the insulation has.You can pick up insulation in rolls or in a Bat.Insulation that comes in these forms is best suited for use between the joists and ceilings well as walls.


Blown in insulation is a type of insulation that is applied using a spray.This type of insulation is best suited for homes that have been completed but are missing insulation.This type of insulation can be difficult to use as it needs to be blown through a gap.If a gap cant be found then a hole has to be cut to apply the spray.This type of insulation is also very good for use between walls that are a unusual shape or for hard to reach places.

 Rigid insulation comes in a few variations of extruded and expanded polystyrene foam, polyurethane foam and polyisocyanurate foam boards.Most of these types of insulation come with a protective foil to keep water from being absorbed by the insulationt,this type of insulation is very efficient considering how thin it is. Rigid insulation's although excellent does require certain fire safety measures though.
