Thermatape™ by Fletcher Insulation - the solution to thermal bridging
Building Code of Australia (BCA) Requirements
Thermal bridging is the term given to heat leakage via a conductive path. Metal framed
structures are particularly susceptible to thermal bridging due to their high conductive
properties. The thermal performance of wall and roofing systems is compromised due to
thermal bridging when a metal frame member connects the outer cladding or roofing with
the inner lining.
Under the BCA (2007) Section 3.12.1.4 a thermal break is needed when a metal framing
member directly connects the external cladding to the internal lining or the internal
environment. The purpose of the thermal break is to ensure that the thermal performance
of the metal framed wall is comparable to that of a similarly clad timber framed wall.
The Quick, Easy Solution to Thermal Bridging
Fletcher Insulation™ Thermatape™ is a simple, easy to use and cost effective solution to
resolving issues regarding thermal bridging on metal frame construction.
The Building Code of Australia (BCA) now contains a requirement for a thermal break to
be installed where materials such as weatherboard, fibre cement sheeting or metal cladding
are fixed directly to the steel frame to reduce the effects of thermal bridging. Manufactured
from premium quality high density polyethylene foam with a self adhesive backing, Thermatape™
is easily adhered to steel frames prior to the installation of cladding.Having been specially
developed for this application, Thermatape™ meets the BCA thermal break requirement of R0.2
Thermatape™ allows you to install tried and proven glasswool batts in the same way as with
timber framing meaning the acoustic performance of the wall system can be improved. Thermatape
also allows you to only treat thermal bridging where it is a problem, on the framing members
rather than treating the entire wall system. The distinctive Fletcher Insulation™ green
colouring of Thermatape™ makes it easy to identify from inferior competitor products.
Stop Heat Leakage
Thermatape™ works by creating a thermal break between the steel frame and the outer
cladding material. The high density polyethylene foam prevents direct contact between the
steel frame and the cladding at the fixing point, thereby, ensuring that the overall thermal
performance of the insulation system is not adversely affected by thermal bridging.
Fletcher Insulation™ Thermatape™ is also very quick and easy to install. Simply
peel off the backing paper and apply to the steel frame before fixing the cladding.
