Permishield® thermo-reflective insulation by Air-Cell Insulation for cladded walls
When you're building with cladded walls you'll know that many
cladding materials require installation with a breathable sarking product behind
it so that vapours are allowed to permeate without damaging the cladding material.
In addition to that you'll still need to install some sort of insulation product.
AIR-CELL® Insulation, Australia's premier insulation innovators, has just made
things a lot easier with its new Permishield®, a revolutionary 3-in-1 breathable
insulation, thermal break, and vapour-permeable sarking. Designed specifically
for wall applications, Permishield® is ideal for insulation behind lightweight
cladding materials that usually require installation with a breathable membrane.
Manufactured with a patented closed-cell, cross-linked foam structure sandwiched
by highly reflective foil surfaces and pierced with tiny, evenly-spaced breather
holes, Permishield® allows building professionals to do away with the traditional
sarking-plus-batts combination in order to achieve thermal compliance as well as
satisfy vapour permeance required by many lightweight wall cladding materials.
AIR-CELL Technical Services Manager, Mr. Keith Anderson, explains: "Conventional
building methodology requires a perforated sarking product as well as bulk
insulation to be installed into the walls. And if it's a steel-framed wall then a
thermal break product is also required. Permishield® is a revolutionary product
that can achieve all this in one go - saving significant time in the construction
process."
Due to the conductive thermal bridging properties of metal and steel, the Building
Code of Australia (BCA) requires that certain buildings with steel-framed walls are
required to include a minimum thermal break of R0.2 between wall cladding and the
steel frame to reduce thermal bridging and conductivity between building elements.
Refer to BCA: Vol. 1 J1.5(e), and Vol. 2 3.12.1.4(d).
As with all AIR-CELL products, Permishield® is fibre-free, non-allergenic,
environmentally friendly and fast and easy to install. Permishield® has been
stringently fire tested and complies with Australian Standards and BCA regulations.
