cavity wall

[imago]

Did I say unsafe? Not as resistant to fire, and unsafe are two different things. In the same way as describing all properties with rewireables as unsafe would be untrue, but to say they are not as safe as those with MCB and/or RCD protection would.

As for the cinder block walls with two coat plaster providing better fire protection than a boarded stud wall, you're wrong.

Really, ....I bet i'm not!! Give me solid clinker block inner walls and partition walls (many were dot and dabbed plasterboard) any day of the week against a stud wall using the thinnest wood frame allowable with plastic sheet vapour locking. It's one of the main reasons for so many total losses with American wooden frame houses... That and the hundreds of screwit type wire connectors used in every house/apartment...loll!!
