Just cement based boards left then as default cladding?

In a country where we have 20 plus million vehicles on the road , all carrying gallons of flammable liquid , where we accept the circa 4 deaths a day on our roads, the story is more about a public body not wanting to accept any potential risk for legal action against them rather than any risk to the occupiers of the properties. Quite why the taxpayer is on the hook for 3.6 million is beyond me, it’s surely the responsibility of the council and it’s Housing Revenue Account.
The logical extension of such attitiudes is that insurers jump onnthe bandwagon and millions of private dwellings across the country become unisurable in the absence of electrical and gas checks, risk assessments etc etc etc, to avoid the minimal risk of injury to visitors to our homes. There’s a risk of making areas of Building Regulations retrospective , which with inevitable mission creep going forward is something that needs avoiding.

+1 for that.

No cavity = no chimney effect !

That should help net zero

Notably the actual timber frame itself all seems to be intact, albeit not in a very happy state.

Posted By: djhA quick search says cladding within 1 m of a boundary needs to be Class B

It's within 1m from the 'Relevant Boundary', which can be a notional line down the middle of a road, railway, canal or river, in the absence of (or even despite) a fence or hedge.

The whole reason for it (AIUI) is to prevent the spread of fire to other buildings. So you might have a garden wall within 1m, but the relevant boundary is the distance to the next nearest building.

If you have a private dwelling more than 1m from the relevant boundary and below 11m in height, I think there are 'currently 'no provisions' for the fire performance on the outside of the wall.

Worth noting that the rules are different for other types of residential building such as care homes, sheltered housing etc. and that there is nuance around unprotected areas (e.g. windows) and cladding over 1mm thickness.

Posted By: djhIn any event the rules are so complicated that it's simpler to just comply and make the surface flame retardant.

Agreed, I was just pointing out that you don't always *have* to make the cladding flame retardant under the regs. It isn't always as simple as

Posted By: djhso timber needs to be painted with a flame retardant

though I agree that some Class B timber might have slowed the spread in the case FosterTom linked to!
