The Palliside Cellular uPVC Weatherboard System is considered a lightweight cladding in terms of NZS3604. With a nominal mass of 4.9kg/m2, Palliside is well under the standard, where the mass must not exceed 30kg/m2.
According to the revised guidance on repairing and rebuilding houses affected by the Canterbury earthquake sequence (Nov 2011, page 39),
“It is noted that light dwellings are likely to perform better than heavy dwellings”. Therefore the use of light timber or steel framing,
lightweight cladding systems and lightweight roofing materials is recommended wherever possible for the rebuilding of houses and
building new houses.
Also, Appendix C of the interim guidance for repairing and rebuilding foundations (in Technical Category, 3 April 2012, page 33) states ,“Where heavy cladding has been damaged to the extent that it requires removal then it is recommended that the cladding be replaced with lightweight (or medium-weight) materials".
As a BRANZ-certified alternative solution, Palliside offers designers, builders and home owners lightweight cladding solutions for both
new builds and reclads. Its Christchurch-based Palliside service provider, Gray Builders, are approved builders for the Canterbury recovery and have an interactive website detailing local new builds and reclads.
