boarding out a garage

[scotty3968]

Hi
My mate wants his garage boarded out and skimmed..which im going to do.
I havnt looked at the job yet but if i remember rightly its only single brick..he wanted it dot n dabbed but im not sure incase of damp etc..
Ive done a double skinned garage before( brick and thermolite block) but not a single brick so i need a bit of advice on what to do
cheers

[scotty3968]

haaaaaaa......the worm...awsome

 

[theclemo]

and thats how u do it

 

[scotty3968]

anyway.....about this garage

 

[theclemo]

its a nice garage

 

[bodplasterer]

Just batten and insulate then board with foil back.

I second that ...........:RpS_thumbup:

 

[nickelarse]

but not too much insulation. or you will get too hotty scotty

 

[theclemo]

scotty 2 hotty what a ballbag he was

 

[twitcher]

don't forget to leave a cavity

 

[spunky]

The cavities already there?

 

[murplastering]

gypliner made for this job

 

[scotty3968]

Batten, insulate, foil back boards,,,,,,,,sorted

Then a 4 arm smash of the ropes just for the hell of it in true scotty2hotty style

i done 12 years of judo...my body couldnt take it...haa

 

[NPS]

i take it its got a damp proof membrane? if so just dot and dab it and keep the boards off the floor as norm

 

[NPS]

if not do as the other lads have said

 

[beddy]

Scotty too hotty lol.

 

[twitcher]

leave a 1 inch cavity between the insulation and the board. Stick a vapour control on too

 

[spunky]

Why 1 inch

 

[murplastering]

still gypliner

 

[lucius]

Loads of ways to do it but a Mur says Gypliner is the modern way to do it,

 

[twitcher]

For some reason the U value goes up if you leave an air gap. That's what Kingspan told us on the phone.

 

[spunky]

It's a ******* garage ?

 

[twitcher]

think it's also to do with avoiding getting a puddle of water under the boards too

 

[twitcher]

the air gap as well as the vapour control layer stops water vapour going through the plasterboard and onto the cold brick. If this happens it can condense and you can see puddles of water on the floor.

 

[flynnyman]

I usually batton then kingspan straight over the top leaving the air gap between the kingspan and the wall then board straight over the top and ive never had any problems just use longer screws.

 

[spunky]

Twitcher are you talking about a vapour barrier direct to the wall before battens?

 

[murplastering]

is this a conversion to a habitable room or just a boarded out garage, is the garage detached or integrall

 

[twitcher]

Twitcher are you talking about a vapour barrier direct to the wall before battens?

I stick the kingspan or whatever to the wall, batten over the insulation with 2 x 1's then stick a vapour barrier on the battens, then board over that

 

[spunky]

The vapour barriers doing nothing a foil back board and cellotex does

 

[twitcher]

that's what the manufacturers specify spunk, look at their pdfs

it makes sense to have a proper vapour barrier or even a breathable one. I don't reckon the foil surface on either the insulation or the board would be enough. A lot of them are still permeable.

have you come across air tightness testing?
