Hi All!
I'm hoping for some advice. We are looking at building a 2-3 story steel frame home in Victoria.
We are conscious of thermal conductivity in the steel frame and would like the house to be energy efficient.
The two main choices are hebel and matrix. I've been given mixed information and would love any feedback or alternatives for a steel frame.
CSR Hebel panels -
Good thermal rating - when used with foil wrap and thermal cavity insulation methods
Substantial additional cost of acrylic render
Can be difficult to install if builder is unfamiliar
Have heard mixed reviews on long term durability
More conventional and aesthetically attractive look for future resale value
James Hardie Scyon Matrix -
Good thermal rating - When used with a full suite of James Hardie insulation products
Easier to install (?)
No need to render and can paint light or dark colours
Unsure of long term durability
I've also been advised that Kingspan Kooltherm k12 is the Gold standard for steelframe insulation. But CSR and James Hardie tend to design their products so that you have to use the full system (smart).
No options seem to be good for noise insulation on a steel frame either.
Any feedback or comments would be greatly appreciated 👍 🙂
