R1.5 Bradford Polymax at 90 mm is the polyester wall batt for a standard 90 mm stud where R1.5 is the target. Non-irritant, low allergen, up to 50% recycled content.
90 mm at R1.5
This is the same R-value as the 75 mm Polymax batt in a deeper cavity, which means it is the one to use when your frame is 90 mm and you do not want a batt that under-fills the bay. A batt narrower or thinner than the cavity leaves an air path, and an air path is worth more lost performance than the difference between two adjacent R-values.
Sizes
Sixteen batts per pack at 1160 mm long: 430 mm wide covering 7.98 m² and 580 mm wide covering 10.77 m².
Polyester or glasswool
Polymax is the no-itch option and the easier one to install without protective kit. Where the job specifically calls for non-combustible material, use a glasswool batt from the Gold range.
On site
Friction fit between the studs, touching the frame on all four sides, no gaps, no compression.
Thermal rating declared to AS/NZS 4859.1 by the manufacturer. Sizes and CSR product codes are in the table below.
