Rockwool Fire Barrier Installation in 1800 Terraced House

In this video we install a rockwool fire barrier in a 1800’s terraced house. Unusually in my experience there was actually a cavity in the party wall. To that end we inserted one layer of the 50mm fire wall into the cavity and the other was secure in the usual fashion. This project took about 9 hours to compete all told.

The project took about 9 hours altogether.
