Bradford Rockwool Fireseal party wall sealer is non-combustible stone wool supplied in long 4000 mm lengths for sealing party walls in multi-residential buildings. Six options, two per pack.
Sized for the run, not the sheet
At 4000 mm long these are made to run a continuous seal rather than to be pieced together out of shorter batts. Fewer joints in a fire seal means fewer places for it to fail, which is the reason the format exists.
Options
Fireseal 50 mm in 300 mm and 360 mm widths, Rockwool 50 mm in 300 mm and 360 mm, and Rockwool 75 mm in 300 mm and 360 mm. Pick the width from the joint you are sealing and the thickness from the specification.
Before you order
Fire performance belongs to the tested system rather than to the material on its own, so work from the specification for the wall and confirm the product suits it. Ask us if you need the manufacturer documentation.
