Insulating your home? Ask the experts
Installing insulation is simple. You can either use a Pink ® Batts ® Approved Installer or do it yourself. Here are some pointers on installing insulation into your roof cavity yourself:
1. Light up the area in which you will be working. Take a good look around for potential hazards, including protruding nails, splinters, bees, wasps, loose boards, wiring and pipe work. 2. To avoid breaking through the ceiling, lay wooden planks between the joists to create a sturdy platform to work from. 3. Ensure any existing insulation is level: you can lay the new stuff on top. 4. Starting furthest away from the roof access hole, take the packed insulation up into the ceiling. Cut along the length of the pack to open. If the packs won’t fit, open them below and have someone hand up each piece. Leave plenty of room for the insulation to expand out. 5. Fit each piece between the joists, the pieces will be slightly over size to ensure a snug friction fit. In most homes this will require two pieces fitted snugly side by side. Make sure the insulation is not squashed or flattened and it has no gaps or folds. 6. If cutting pieces to fit, use the straight edge, knife and cutting board. Cut the piece about 10-20mm over size to ensure a good friction fit. Never cut on the joist. 7. Install the insulation completely over the top plate (this is the piece of timber that makes up the top of your exterior wall), use the rod to push the insulation into the tight spots you can’t get to.
Installing around wiring, plumbing and lights
You may need to cut a hole in your insulation to get a good fit around recessed downlights. Older lights will need a clearance, so it may be worth replacing them if you want the snuggest fit. Slit the insulation along the face to fit snugly around pipes and plumbing. It is best to sit wiring over the top of insulation. In homes with old wiring (pre 1989) the wiring shouldn’t be covered at all, as it can overheat and fail.
