Overview

One of the most important things you can do to improve the energy efficiency of your home is to ensure that your walls are insulated. Many older homes have no insulation in the wall cavities and this can lead to significantly higher energy bills as you struggle to maintain a comfortable temperature inside your home.

Here are three great reasons to look at insulating your walls

  1. Efficient heating/cooling – Good insulation stops the flow of heatinto and out of the home. This makes your home more energy efficient all year round.
  2. Better Acoustics – Insulating walls can reduce annoying sounds from outdoors and it reduces sound carrying from one room to another
  3. Improved Moisture Control – Moisture trapped within your home’s walls can cause all sorts of problems. If this water condenses within the walls, it can cause rot, mildew or even frozen patches of moisture that cause staining when they melt.

While most homes built today have both ceiling and external wall insulation, insulating internal walls is still not as common. And in older homes, can be quite rare. There are good reasons to insulate your internal walls though.  Insulating your internal walls reduces sound transfer between rooms and can save on energy costs, especially if your house has room that are not in use all year round. Seasonal used rooms, guest rooms and even storage rooms are expensive to heat and cool. Interior wall insulation will reduce heat transfer.

Interior walls that separate living spaces in apartments/duplexes in particular frequently require insulation – not only for thermal and acoustic reasons, but also to prevent the spread of fire between buildings.

In existing homes it is possible to insulate internal walls without removing the gyprock and Cosywrap Insulation prides itself on our expertise in this area.  Our team will pump either cellulose or rockwool blow in insulation by drilling holes into the top of each stud and pumping the insulation in with our specialised equipment. We then patch any holes ready for painting!

Cavity brick walls have high thermal mass, but without insulation are usually too cold in winter and often too hot in summer if exposed to prolonged heat wave conditions. If the cavity is insulated, the internal thermal mass (i.e. the internal brick skin) is protected from external temperature changes, and becomes highly effective at regulating temperatures within the home.

You can insulate existing cavities by sealing the bottom of the cavity if it is open to the subfloor, and pumping in loose bulk material to a measured density.

Cosywrap introduced the concept of existing wall insulation into Australia in 1985, after investigating it’s use in the UK and Europe. We have continued to develop our expertise over the last 30 years, and we understand how to ensure you receive full insulation, done correctly, and using the CSIRO approved Rockwool insulation.

Cavity Wall Rockwool is the only product approved by the CSIRO and the Building Code of Australia for installation in existing walls. Rockwool is manufactured in a water repellent form that can be easily blown into the cavity of Brick Veneer or double brick walls, and is a thermal and acoustic product.
