Bricking up garage door, brick and block vs brick and batten/celotex

[0Floz0]

Hi all,

Posted in building regs and got some good answers but have a different question which needs answering.

So, I'm having my driveway redone and whilst they're knocking out things around the garage I asked them to see what the situation is regarding the slab for the garage. Unfortunately, its only 3 inches deep on the face where the door is and not the 6 inches required by building regs to build a wall with window on. So having spoken with them I've decided I'd rather install a lintel vs digging down 1 metre and infilling with concrete.

My question is, what would everyone go for in terms of building on top of this. If I go for brick and block I need 2 lintels. If I go with brick and batten its 1 lintel but then the cost of celotex. What would be cheaper out of the two (or is there not much in it?) and is one going to be significantly better from an insulation perspective?

Looking to make a call on it tonight so as not to hold up the driveway build tomorrow.

Cheers

I have always preferred the traditional double skin.
Why do you need 2 lintels?
If you use a metal lintel, it goes across both skins.
They're not much more expensive than 2 concrete lintels and you don't have to worry about the cavity.

I just assumed it might be a pain to get a metal lintel quickly. The total length of the lintel is 2,200mm. 2,000mm for the opening and 100mm each side. to rest on the bricks.

Why do you prefer the double skin method? Isn't it more expensive? I can batten myself but would need someone to do the blockwork, imagine they'd be able to do the brick and block in the same day?

Oh and two lintels is one for each skin.

It's my personal preference having attended many failed single skin insulated constructions.
A metal lintel is easy to source and easy to install, although more expensive.
It's my personal preference to spend a bit more and have decades of trouble free usage, but that's just me.

You need at least 150mm each side, so 2400

Single skin walls don't fail unless whoever built it was crap.

Exactly.
Seen many of them with severe damp issues.
That celotex needs to be installed properly, otherwise it creates lots of problems.

When you said steel I assumed you meant an I beam. I guess that would be easier to fit than knocking the brick out. Not much differential in cost either. If anything it’s cheaper than 2 concrete lintels.

I’m sure the building control chap told me it was 100mm each side but guess it doesn’t matter too much as I won’t find a 2,300mm one anyway.

any recommendations on where to get them locally? Major stores ideally so I can just nip in. Can’t wait for an eBay delivery. I’m based in Warwickshire. But assume the major places will sell them?

My local selco has them in stock.
Sometimes wickes also.
