Product Criteria

Design requirements

GreenStuf Masonry Wall Blanket is designed to be friction-fitted between strapping or battens on masonry walls. 

GreenStuf Masonry Wall Blanket must be installed only when the building is enclosed and when construction materials have achieved the required maximum moisture content or less.

GreenStuf Masonry Wall Blanket might not be suitable for some external wall applications as stipulated in NZBC C1-C6 Protection from fire. Please consult a fire engineer before specifying GreenStuf insulation in external walls.

Installation requirements

GreenStuf Masonry Wall Blanket must be installed according to the Install Instructions included in each GreenStuf pack and NZS 4246.

GreenStuf Masonry Wall Blanket must be released from packaging and allowed to re-loft prior to installation. The time to re-loft depends upon the length of time the product has been packaged and stored, as well as the environmental conditions it is left in after being taken out from its packaging.

GreenStuf Masonry Wall Blanket must be neatly friction-fitted between strapping or battens to ensure no gaps.

GreenStuf Masonry Wall Blanket must be stapled to the strapping or battens on both sides and at the top of each blanket to hold the insulation until wall linings are in place.

Refer to NZS 4246 for required minimum clearances to heating appliances and light fittings.

Where possible, insulation should be placed beneath electrical wiring or plumbing.

Maintenance requirements

GreenStuf Masonry Wall Blanket must not be compressed over its serviceable life. Compressing GreenStuf Masonry Wall Blanket can lead to reduced thermal performance.

If GreenStuf Masonry Wall Blanket becomes damp or wet while in service, it must be removed and the cause of dampness must be resolved. Cavities must be clean and dry before new insulation is placed.
