Step 1 - Place the packs onto the roof area. Start from the farthest point from the manhole and work from one pack before opening the next.
Step 2 - Stand on joists only, fit knee board over at least two joists. Fit batts snugly between the joists, using your batt poker to slide the batts to the outside edge of the wall plate. Ensure batts are fitted with no gaps.
Step 3 - Leave a 25mm minimum clearance around vents, chimneys and downlights. Do not cover light transformers
Step 1 - Clean off excessive mortar from brickwork and studwork.
Step 2 - Run 1 or 2 vertical tapes between studs. Attach tape to the top plate, noggin and bottom plate by stapling. This prevents wall batts from bridging the brick cavity.
Step 3 - Fit the batts to the frame between studs. Press the batts into place so that the insulation fits flushwith the face of the frame. This will avoid the batts touching the external brick wall.
HEALTH AND SAFETY TIPS:
Electrical wiring must be appropriately sized or it may overheat when covered by insulation. Have it inspected by a licensed electrician to ensure it can be safely covered by insulation.
Allow clearance around hot flues, exhaust fans, appliances and fittings. For light fittings, where the manufacturer’s installation instructions do not provide information on required clearances, the light fitting can be installed using a suitable Australian Standards approved enclosure for electrical and fire safety. Where barriers are not used, ensure a minimum clearance of 50mm above the incandescent lights and 100mm side clearance to any structural members and for recessed halogen lights a minimum of 200mm above and side clearance to any structural member, with a 50mm gap for lighting transformers. Refer to the Australian/New Zealand Wiring Rules (Australian/New Zealand Standard (AS/NZS) 3000:2007) for more detailed information.
Wear protective clothing, gloves and a face mask when installing glasswool, mineral wool or cellulose fibre insulation. These materials can cause short term irritation to skin, eyes and upper respiratory tract. It is good practice to always wear protective equipment when working in dusty roof spaces.
Ceiling fires have increased significantly with the more common use of downlights that penetrate the ceiling. Care must be taken to ensure minimum clearances around downlights are maintained and that transformers are not underneath the insulation. Wherever possible avoid recessed light fittings as these are a major source of heat loss.
Wear adequate eye protection when installing reflective insulation, as it can cause dangerous glare. Be aware of the increased risk of sunburn.
Insulation materials containing reflective foil must be kept clear of electrical wiring and fittings, and should not be secured using metal staples
