For Walls
- Check the label to make sure the R-Rating matches what is required.
- Cut the plastic wrapper and allow the segments to expand.
- For stud spacings of 600mm use 580mm segments and for stud spacings of 450mm use 430mm segments. For other stud spacings cut segments 5-10mm oversize to gain a tight friction fit.
- Where there is no building paper like internal garage walls hold the insulation in by using the polypropylene tape. Run the tape horizontally two rows per cavity approx 300mm apart on both sides of the insulation. Ensure roof void walls are strapped.
- Use the small off cuts to fill the small cavities in corners or above windows.
For Ceilings when the lining has not been installed (New Housing)
- Check the label to make sure the R-Rating matches what is required.
- Cut the plastic wrapper and allow the segments to expand.
- For 450mm and 900mm joist or truss spacings use 430mm segments and for 600mm joist or truss spacings use 580mm segments.
- Using the two sticks place the pieces on top of the ceiling battens running from the top plate on one side to the top plate on the other side placing the pieces end on end. The insulation must be under the electrical cables where possible.
- Make sure all cavities are filled, the insulation is not folded and there should be no gaps.
For Ceilings when the lining has been installed (Existing Housing)
- Check the label to make sure the R-Rating matches what is required.
- Place the bales into the roof space. Cut the plastic wrapper and allow the segments to expand.
- Move to the furtherest point from the man hole using the kneeling board and standing on joists only. Place the segments between the joists or trusses and place them from the outer wall plate inwards using the sticks where required. Ensure there are no folds or gaps. Cut where necessary to gain a good fit.
- Ensure the segments are at least 50mm over the top plate but must be at least 25mm away from the roof or underlay to prevent wicking of water into the insulation.
- The insulation must be under the electrical cables where possible.
- Make sure there is a 50mm minimum clearance around vents and chimneys and 200mm around down lights and unducted fan units. In New Zealand refer to NZS 4246:2006 Incorporating Amendment No. 1 for more details.
When the job is complete ensure there is a complete insulation envelope, that there are no folds or gaps.
Moisture
Taita Segment Glass wool Insulation will not absorb water but retain water. Care must be taken to ensure that the insulation does not wet pre and post installation. The following measure will help prevent the insulation from damping:
- Do not install the insulation against an exterior masonry product. (i.e exterior concrete block wall.)
- Timber framing should be sufficiently dry before the insulation is installed.
- The building paper must be installed before the insulation and in extreme cases the exterior cladding should be installed before the insulation.
- Wherever possible vents from bathrooms should be ducted to the soffit rather than directly in to the ceiling cavity.
- Ensure the bales of insulation are stored in dry conditions.
Safety & Health
Please note the following notes:
- Ensure the dust masks are used.
- Wear overalls and a shirt with long sleeves.
- Ensure that there is sufficient light in the working areas.
- Take care around electrical wires when cutting and stapling.
- If working in the ceiling is alert for exposed nails, pipes and timber that will be unable to take your weight.
- Electric cables and equipment partially or completely covered with glass wool may overheat and fail. This applies to wiring installed prior to 1989. Read the instructions accompanying this pack.
- Wash work clothes separately from other clothes.
- In case of contact with eyes, rinse immediately with plenty of water.
- In case of skin itching, wash skin with soap and water.
