Regs for floor and roof insulation?

[d000hg]

yes it is but I thought a possible future dwelling was now being discussed.As somebody has said SBEM for commercial,SAP for dwelling. That should put the cat among the pigeons

Are the two fundamentally different out of curiosity? Like, trying to measure different things?

this will give a U value for floor, wall, roof. If each is in line with regs, then that should be OK, I guess.

guess being correct

what is the proposed floor and roof construction , does anybody know don't think it will be a 'timber raft' unless it is floating on water

It's a typical suspended wooden floor i.e. not a solid concrete base. This is mounted on pilings so the whole 'raft' is 'floating' above the ground on 28 metal rods. I believe the 'raft' is 6x2" treated timber so I suppose there is up to 6" insulation space. Then flooring would be standard 22mm Weyroc or equivalent.

Roof: some sort of shingles on battens, factory spec has this panelled underneath but it's common to find space for insulation, with a slight re-jig to the design. I think up to 150mm is easy to get in, beyond that probably more modifications to get everything to fit together.

To answer the question you meant to ask: No you can't just insulate the roof and floor to a very high level to make up for sub par walls.

In a bit of a jump, what exactly is the point of regulations, to go to basics? The guy we talked to today from the council pretty much said (maybe he shouldn't) that they are really only relevant when it comes to selling a property,

You are right he shouldn't have said that. The point of building regulations is to ensure buildings are built to something like a decent standard which seems a good idea to me.

It's within our curtilage, a structure we will build in our garden, but may then allow a company to operate out of. Does that make it a commercial or residential property (there are no bedrooms)? Or both? It could later be used for something else.

what exactly have you got planning permission for ,what does it say on the consent notice

The BC guy mentioned this but said he has no preference how we classify it.

strange thing for a BCO to say

 

[Leofric]

And even then getting a definitive idea what the regs says on each line isn't something anyone here knows

Nobody on here knows anything , and if they did you would only query their answer

Cant you just take 50mm insulation off the wall and stick it on the floor?

I mean its the same amount of insulation, right?
