You’d never trust anything that doesn’t age well.
So always choose the insulation that lasts a lifetime.
We’re committed to ensuring that every piece of Pink® Batts® insulation we manufacture provides the same quality, performance and durability. That’s why we offer a Lifetime Warranty on Pink® Batts® BRANZ appraised wall and ceiling products. So you can be confident they’ll meet or exceed current New Zealand Building Code requirements for the lifetime of a home.
Some advice from research
The research identi ed several key ndings:
● There is not an extensive history of re incidents involving duct-
work in New Zealand.
● AS/NZS 1530.3:1999, and therefore AS 4254-2012 Ductwork for
air-handling systems in buildings (Parts 1 and 2), does a poor job in discriminating re performance and hazard of thermoplastic ductwork insulation.
● Thegroupnumbersystemforregulatingreactionto reproperties is a suitable basis for evaluating the re hazard of rigid and exible ductwork.
● Adeemed-to-complyclassi cationforcommondesignsofpolyester- insulated exible duct would remove the need for duplicate testing of the same duct design by di erent fabricators.
● Combustibleductworkshouldnotbeinstalledwithin re-protected exits.
Note The research was jointly funded from the Building Research Levy and the Ministry of Business, Innovation and Employment.
The ndings are in BRANZ Study Report SR339 Fire behaviour of HVAC duct and pipe insulation materials available from www.branz.co.nz/shop.
