Insulation made easy
To reduce heat gain in summer and prevent heat loss in winter, install insulation.
Insulation also helps appliances to run more efficiently, reducing electricity usage and taking pressure off the budget.
It makes sense to invest in good-quality insulation, and if you’re building a new home or carrying out major renovations, installing insulation is mandatory to meet energy-efficiency standards.
The placement of batts in internal and external walls usually happens during a build or renovation, as once the internal lining is fixed in position there is no access to the wall cavities.
Begin by measuring the surface area in square metres to calculate the number of packs required for the job, then purchase batts with the required R-value and width.
Batts come in 430 and 580mm widths to match 450 and 600mm stud spacings.
Check the stud depth to ensure the specified R-value batts fit snugly in the cavity. Before commencing installation, check whether any electrical wiring is connected to the meter box.
Also, make sure the power is turned off and any safety hazards are identified.
At external stud walls, the batts must be kept within the frame and not touch the brickwork or mortar.
To keep the batts contained, staple one vertical strap or stringline in position or two horizontal straps or stringlines for each noggin opening.
When all the batts are in position inside the stud framework, the wall linings can be secured.
