The Earthwool® glasswool insulation: Ceiling segment range is a new generation of softer, safer and more environmentally friendly glasswool insulation.
Advanced compression packaging reduces handling time and the risk of damage in transit and on-site.
Segments are the traditional insulation product for ceilings, supplied in pre-cut rectangles at 430mm widths to suit the most common ceiling joist centres.
Earthwool glasswool insulation: Ceiling segments are recommended for installation from either below ceiling joists (i.e. within the room) or from above ceiling joists (i.e. within the ceiling space).
Scope of use
Supply and install the selected Earthwool glasswool insulation to walls, floors, ceilings, roofs and other areas as identified on the drawings, complete with accessories.
All aspects of this work shall be in complete accordance with Knauf Insulation product manuals and installation guides, (check www.knaufinsulation.co.nz, or call 0800 562 834 for the latest editions), Earthwool glasswool insulation BRANZ Appraisal, other relevant product manufacturers' recommendations, and as shown on the drawings.
No substitutions are permitted for Earthwool glasswool insulation.

Earthwool glasswool insulation is an Acceptable Solution in terms of New Zealand Building Code Compliance.
Earthwool glasswool insulation thermal resistance (R-value) has been determined by testing to AS/NZS 4859.1 which is an acceptable method.
The product has and can make available the following additional evidence to support the above statements:
Earthwool glasswool insulation: Ceiling segments provide a cost effective thermal and acoustical barrier for energy efficient construction. The insulation’s consistent quality, low dust, and clean cutting resilient wool makes installation fast.
Earthwool glasswool insulation: Ceiling segments can be used in timber and metal frame applications in residential and commercial structures.
Knauf Insulation offers Earthwool glasswool insulation: Ceiling segments in a wide range of sizes and R-values.Earthwool glasswool insulation can be used for cavity walls, floors, ceilings, attics, basements and crawlspaces.
It is highly resilient, recovering quickly to full thickness. It also greatly reduces the transmission of noise in the home.
Installation of Earthwool glasswool insulation must be completed by an installer with an understanding of insulation installation, in accordance with the instructions given within the Technical Literature, Installation Instructions and BRANZ Appraisal.
Installation of Earthwool glasswool insulation must be in accordance with the Knauf Insulation’s Technical Literature, Installation Instructions and BRANZ Appraisal.
NZS 4246 should be used as a guide for installing insulation in residential buildings in New Zealand.
The product must be installed only when the building is enclosed and when the construction materials have achieved the required maximum moisture content or less, to ensure the insulation does not become wet.
The building must be maintained weatherproof at all times.
If, during normal routine maintenance it is discovered that moisture has entered the building envelope, or that dampness has occurred because of leaking plumbing or some other source, then that source must be repaired immediately.
Wet or damp insulation must be removed and then replaced with new insulation of an equivalent thermal rating.
Cavities must be clean, dry and free of all contaminants and mould before fitting new insulation.
NZS 4246 Paragraph 3.3 gives guidance on thermal insulation maintenance due to water damage.
Earthwool glasswool insulation: Ceiling segments are free from CFCs, HCFCs and any other material with ozone depletion potential in its manufacture and content and represents no known threat to the environment.
Earthwool glasswool insulation: Ceiling segments’ manufacture has a low impact on the environment and is classified as Zero ODP and Zero GWP.
Knauf Insulation mineral wool products with ECOSE Technology benefit from a revolutionary, bio-based, formaldehyde-free binder technology, based on rapidly renewable materials, instead of petro-based chemicals. It reduces embodied energy and delivers superior environmental sustainability.
The technology has been developed for Knauf Insulation's glass and rock mineral wool products, enhancing their environmental credentials without affecting the thermal, acoustic or fire performance. Insulation products made with ECOSE Technology contain no dye or artificial colours - the colour is completely natural.
