Ametalin Non-combustible ThermalBreak Strip is a 10 mm high temperature insulation felt, made to give an R0.2 thermal break on a steel frame without introducing any combustible material. Stocked as 45 mm x 1.2 m strips in packs of 50, self-adhesive or without adhesive, and as 90 mm x 1.2 m self-adhesive strips in packs of 25.
The problem it solves
Every steel frame that touches its cladding needs a thermal break, and the NCC asks for R0.2. On a normal job a foam strip does that. In a Type A or Type B construction, or a facade that has to be non-combustible, a foam strip is the one line item that quietly breaks the claim. This strip is Not Deemed Combustible when tested to AS 1530.1, so it can go into those walls.
The numbers
Material R-value R0.2 at 23 degrees to AS/NZS 4859:2018, thermal conductivity 0.05 W/m·K, density 288 kg/m³, compression rate over 300 kPa and a maximum temperature of 1300 degrees. It complies with AS 3959-2018 for residential and commercial systems up to and including BAL-FZ.
Where it goes
Continuous facades in Type A and B construction, fire rated boundary walls, and any steel frame where R0.2 is required and the material has to be non-combustible. Ametalin also flag it for NCC 2022 vapour permeable roofs in all BALs.
On site
Cuts to length, chemically stable and compression resistant. Termite, mould and mildew resistant. It goes on the outside of the framing after the membrane, and the cladding should follow straight away. The self-adhesive strip peels and presses on. The strip without adhesive is held with flat head screws or short pieces of tape, which can come out as the cladding goes on. Other widths and lengths are made to order.

Fitting notes
Install to the exterior side of the structural framing after the pliable building membrane is on, and fit the cladding at the same time for best durability and performance. Surfaces must be clean, dry and free of dirt, grease and oil. Self-adhesive strip: peel the release liner, centre the strip on the framing member and press firmly. Strip without adhesive: hold it on the steel with flat head screws or short pieces of tape before the cladding goes on; the fixings can come out as the cladding is applied. Cuts to any length or shape. Store in a clean dry place out of direct sunlight.
Figures are taken from the Ametalin technical data sheet for Ametalin Non-combustible ThermalBreak Strip, APM-45939-0, which also gives the fixing method for the strip without adhesive. The 90 mm strip and the strip without adhesive are supplied under product codes NCTBSA-901200 and NCTBS-451200 by RM Industries, the national distributor. The manufacturer document is linked above.
Common questions
Why not just use the foam ThermalBreak strip?
Because XPE foam is combustible. In a Type A or Type B construction, or on a facade that has to be non-combustible, the foam strip breaks the claim. This one is Not Deemed Combustible to AS 1530.1.
What R-value does it give?
R0.2 at 23 degrees to AS/NZS 4859:2018, which is exactly the NCC requirement for a steel frame thermal break.
Is it rated for bushfire areas?
It complies with AS 3959-2018 for residential and commercial building systems up to and including BAL-FZ, which is the Flame Zone.
Will it crush under the cladding fixings?
Compression rate is over 300 kPa and the density is 288 kg/m³, so it holds its thickness under normal cladding loads.
How much frame does a pack cover?
A pack of 50 strips at 1.2 m is 60 m of framing member. On a 2.4 m wall that is two strips per stud, so about 25 studs per pack. The 90 mm pack of 25 strips is 30 m.
Self-adhesive or without adhesive?
The self-adhesive strip has an acrylic adhesive under a release liner: peel, centre it on the member and press. The strip without adhesive is held on the steel with flat head screws or short pieces of tape until the cladding goes on, as the Ametalin data sheet describes. Both are the same 10 mm R0.2 felt.
Can I get it in other sizes?
We stock 45 mm strips with or without adhesive and a 90 mm self-adhesive strip, all 1.2 m long. Ametalin make other widths and lengths to order. Ask us and we will quote.
