Product Criteria
Design requirements
GreenStuf BIB is designed to be friction fitted between ceiling or roof framing members. GreenStuf BIB can also be laid directly over ceiling lining, over ceiling battens or joist/truss chords.
Minimum separation of 25mm between GreenStuf BIB and any rigid substrate or flexible roof underlay must be ensured to prevent moisture transfer and provide roof ventilation.
If it is not possible to achieve a 25mm gap between the underlay and insulation, counterbattens can be used to provide a vent
Installation requirements
GreenStuf Thermal Underfloor Blanket must be installed according to the Install Instructions included in each GreenStuf pack and NZS 4246.
GreenStuf Thermal Underfloor Blanket must be released from packaging and allowed to re-loft prior to installation.
GreenStuf Thermal Underfloor Blanket must be wider than the space between the joists for stapling. Refer to install instructions.
A clear 100mm gap must be left around waste pipes that penetrate through the floor to allow for future service.
Refer to NZS 4246 for required minimum clearances to heating appliances, light fittings and downlights.
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.
