Wall Insulation Batts
To meet the Building Code of Australia, it is obligatory to install wall insulation for all Australian homes. Installing insulation to external walls generally makes a massive difference to the thermal performance of your home. Wall insulation acts as a barrier to 25% of heat flow in and out through wall. When installed correctly, it will help to keep your home cool in summer and warm in winter while reducing the greenhouse gas emission and energy bills by 40% to 45%.
Buy wall insulation according to the wall type
There is range of wall insulation types, which might be suitable according to the wall type. In Victoria, there are three diverse wall types and to get the maximum benefits from installing insulation you should choose the correct wall insulation type.
Cavity Brick walls – these homes have comparatively higher R value and will lose less heat in winter and enter less heat during summer. Adding wall insulation to the timber frame will enforce holding heat inside the home during winter and blocking heat come in to the home during summer.
Brick veneer and reverse brick veneer walls- bricks heat up in summer and radiate heat in the evening while they stay cold and absorb heat from the house in winter. So wall insulation is required to stay comfortable.
Weather board and timber framed walls – these walls have lower R value and it is completely rely on insulation to stay thermally comfortable.
how to install wall insulation
The process of installing wall insulation is depending on the type of the walls.
For walls with cavity brick, brick veneer and reverse brick veneer, insulation can be installed by pumping loose bulk material through the cavity. This can be done using two methods.
- Small polystyrene balls made using carbon dioxide and coated with non-toxic bonding agent are pumped through the cavity in walls around the house and they locks into the place with the help of bonding agent.
- Using mineral fibres, which are also referred as mineral wool, are blown into the wall cavity either in the top of the cavity or through small holes on the wall. Then these holes are sealed after the process. To makes sure that the wall cavity remains dry, these mineral fibres are treated with moisture repellent.
When installing wall insulation in to timber frame walls, the loose bulk method can be used. These wall insulation batts can be installed directly in to the spaces between noggins and stud frames. If you are doing this to an already built house, the external cladding or internal plasterboard lining need to be removed. This method is easier method if you are installing wall insulation batts during the construction stage of the house.
