PIRBOARD ULTRA is the product with the higher surface performance in the PIRBOARD range. The core is the same as in the other three products: PIR, 0.022 W/mK thermal conductivity, B-s1-d0 fire class.
The board size is 1200 x 2400 mm, with ten thickness options between 20 and 200 mm. What separates the products in the range is not the core but the surface facing, and the facing determines where the board can be used.
It is used in floors where section thickness is limited, in duct and services voids, and in insulation added to an existing building. To choose according to surface type, compare the four products on the thermal insulation page.
