- Determine the most suitable product for your project. Walls can be insulated using rolls or batts. Insulation is available in varying widths and thicknesses to suit most framing spaces.
- To calculate the number of packs needed, determine the area (m2 ) to be insulated by multiplying the length by the width or wall height. The number of m2 of insulation material is clearly marked on each pack. Divide the total area to be insulated by the m2 in a pack to determine the number of packs required (don’t forget to round up to the nearest whole pack). Allowances should be made for areas that are unable to be insulated. You can also use the Ecolife Solutions online insulation calculator.
- Don’t take the insulation out of the packaging until you’re in position and ready to install.
- Before installation check that the product selected matches the specification.
- Ensure that the insulation has lofted to the nominal thickness, if required, gently agitate the insulation by gently shaking or bouncing it on its side until it recovers to thickness stated on the label.
- Where installing around wall lights or heat sources consult the appliance manufacturer’s instructions for appropriate clearances. Additional guidance is provided in AS 3999 and NZS 4246.
- When installing insulation between framing members, ensure that you achieve a snug fit avoiding any gaps, tucks and folds.
- It is recommended that you select products that have the same thickness as the cavity. In circumstances where the cavity is deeper than the product selected, adequate support must be provided.
- Make sure insulation fits snugly against top and bottom wall plates. The front face of the batt should be flush with the inside face of the framing.
- For metal frame walls, install insulation according to the relevant building code. Friction fit one side of the batt into the metal C-channel and butt the other edge against the metal stud. Install insulation to cover the full height of the wall.
- Use off cuts to insulate small and hard to fit areas.
- Attention to detail is very important. Make sure all areas are insulated, behind electrical outlets, plumbing and services.
- Seal all penetrations in exterior walls with insulation or foam sealants.
- Complete a final check of the installation ensuring all areas have been insulated and that you have an even and consistent layer of insulation.
- Finish your project by removing all packaging and disposing of all rubbish and excess insulation responsibly.
- We recommend that once completed another person checks the work to ensure it has been installed according to required standards.
