Frequently asked questions
Does R2.5 Hi-Performance fit a standard 90 mm wall cavity?
Yes. The 90 mm thickness fits precisely within a standard 90 mm timber-stud cavity, achieving the full R2.5 rating without compressing the batt or reducing thermal performance.
How does R2.5 compare with R2.0 for energy efficiency?
R-value represents thermal resistance. A higher R-value means greater resistance to heat flow. R2.5 provides 25% more thermal resistance than R2.0, making it better suited to cooler Australian climate zones or homes targeting higher energy ratings.
Is any ongoing maintenance required?
No. Bradford Gold Hi-Performance wall batts require no maintenance or replacement once installed within the wall cavity, and are backed by a 70-year performance warranty.
