When installed correctly, Pink Batts are the most cost effective method of reducing household energy bills.
What you need
- A sharp knife and cutting board
- Kneeling board (to span at least two ceiling joists)
- Lighting (if required)
- Gloves are recommended
- A dusk mask (recommended in enclosed spaces)
- Goggles (recommended if working overhead)
The first step
Check the distance between the studs before purchasing your batts. Measure from the centre of one timber stud.ceiling joist to the next. For 450mm spacing use 430mm wide batts, for 600mm spacing use 580mm batts.
Ceilings
Standard
- Batt packs are designed to fit in 99% of average size manholes.
- Work out how many packs you need and pass them unopened through the manhole.
- Spread the packs around inside the ceiling before opening them.
- Never walk on plaster ceilings. Stand on ceiling joists only.
- Place kneeling board across at least two ceiling joists before kneeling.
- Lay batts between ceiling joists starting at the furthest point from the manhole.
- Butt the batts closely together to ensure there are no gaps left at joints.
- Cut the batts to the required size to fit around vents, exhaust fans and flue pipes, allowing a space of at least 25mm.
- Continue until the entire ceiling area is covered, and extending a minimum of 50mm onto the external wall top plate.
- Offcuts may be used to fill small spaces to ensure a complete coverage.
- Be extremely careful of electrical wiring in the ceiling. Where possible, place the batts underneath electrical wires or use a spacer to create an air gap between electrical wiring and insulation.
Cathedral / Raked Ceilings
- In the case of cathedral ceilings, the batts should be installed prior to fixing the plasterboard.
- Batts should be supported by string or twine, running at right angles to the ceiling joists so they remain in place until the plasterboard is installed.
Walls
Brick veneer
- It is important that the batts are secured so they cannot fall into the cavity or come in contact with the outer brickwork, allowing moisture to pass from the exterior wall to the internal lining.
- Foil insulation or long lasting string/twine should be fixed across the exterior face of the frame before installing the batts from the inside.
- Where string/twine is used, 2 lengths of twine should be fixed between each set of studs from the top to the bottom, running parallel with the studs and evenly spaced.
- Butt the batts closely together between studs to ensure there are no gaps left at joints.
Fibre cement or weatherboard cladding
- A breathable foil or building paper must be used so as not to cause moisture build up.
- Butt the batts closely together between studs to ensure there are no gaps left at joints.
Cavity brick walls (double brick)
- Batts are not recommended for use in cavity brick construction.
