NZ Foam Ceiling Insulation 85mm-R-3.60, 100mm-R-4.46, 120mm-R-5.36
Description

NZ Foam provides a ceiling insulation system that can enhance the reduction of heat/cold loss that will exceed the minimum R-value under the New Zealand Building Code (NZBC)(1). The application of the system can be installed on top of interior linings. 

A spray-in-place insulation is created to provide a durable air-tight barrier to heat and cold. The foam is a closed cell, medium density 2-part polyurethane foam with low thermal conductivity that will adhere to numerous substrates.

NZ Foam products not only provides thermal insulation but creates an air and moisture seal, giving greater control over the interior environment of the building.

Key Features

Performance benefits:

  • Stable thermal performance
  • Meets fire test standard AS1366
  • Completely inert within 24 hours and no further off-gasing
  • High R-values as required by the New Zealand Building Code (NZBC)(1)
  • 85mm — R-value 3.60
  • 100mm — R-value 4.46
  • 120mm — R-value 5.36
  • Good sound control
  • Maintains an air seal even after seasonal expansion/contraction of building assembly
  • Less than 1% water absorption
  • Supports indoor air quality by blocking air infiltration and mass transfer of moisture that may cause mould

Characteristics:

  • Closed cell semi-rigid structure
  • Medium density (2lb)
  • Expands ~30 times from liquid state
  • Application thickness is not limited
  • Will not harm electrical wiring, plumbing or other building components
  • Low global warming potential
Scope of Use

The product is usually site applied using special spray equipment, trained applicators and under strict quality control conditions.

Typically used for application into timber, concrete and/or light gauge steel framing of walls, floors, and in roofs to meet thermal performance design requirements.

Limitations on Use

Subject to the following:

  • All designs and construction shall be within the requirements and the guidelines set out in the ASCC Technical Manual ver 1.1 dated 1 July 2016, which includes ensuring the substrate to be properly assessed before application. Other uses are outside the scope of this certificate.
  • For application to light gauge steel framing, using a 400mm stud spacing and 63mm product, a 0.7 R-value thermal break is re-quired in all climate zones, and for 600mm stud spacings using 90mm thickness of product a .5 R-value thermal break is re-quired in all climate zones.
  • Substrates are to comply with those specified in the ASCC Technical Manual ver 1.1 dated 1 July 2016, and the ASCC Building Product Quality Plan ver 2.1;
  • Installation shall be performed by ASCC trained and approved installers. Maintenance where required shall be in accordance with the ASCC Building Product Quality Plan ver 2.1
