Stopping condensation in garage

I've got a garage roofed with asbestos.

On cold, damp mornings the roof drips. Any suggestions on how to get
around this?

I've thought about lining the roof with insulation and foil-backed
plasterboard. Any options that are cheaper than this? Some sort of
spray on foam insulation that costs very little would be ideal...

Move.

 

Remove the roof or move to a warm country where it never rains.

 

I'd have thought you'd still have the problem of trapped moisture, as
insulation would only slow the process down.

How about improving the ventilation, so that a limited amount of air can
pass through the garage thus removing the condensation?

 

There's open space at the front, back and sides. It's something
asbestos seems to do, based on my observations of open farm buildings.

I thought that sealing the 'roof' bit would keep the warmer air below
the roof. In any case since it only happens occasionally it would
(probably) dry out eventually... Chicken wire over the insulation may
be wise though.

 

Polyurethane foam spray insulation is the thing for agribuildings, but
helluva pricey for small areas.

Cheapest way would be fit rockwool or aeroboard batts to the underside,
but you'd need to hold them up, which is where your chickenwire would
come in.

On UKRM you're just a **** with opinions.

 

I was worried that would be the answer.

I think it's rockwoll, chickenwire and (foil lined) plasterboard then,
at least that way if I paint it white I'll have decent lighting, maybe.

Then again I bought two 500W halogen units on a stand, 19 quid...
absolutely brilliant, turns night into day. Well, within a small area
anyway.

 

I lined the shed roof and walls by glueing (with a building adhesive
like Gripfix) foil backed Celotex. Much more efficient than Rockwool and
the extra cost can be offset by the fact that you don't need to buy
plasterboard. You can by second grade stuff on the interweb but I don't
have the address to hand. 1" thick should do it.

Can't you use insulating boards that fit between the rafters with simple
battens holding them in place.

Or simply sheet the rockwool in place with plasterboard or hardboard.

 

Belts and braces. If the rockwool were to get wet I'd like something to
restrain it in case the plaster gets soaked and collapses...

It's 'safe' asbestos.

As a kid I put up a large sheds using the stuff. At the end of the days
I'd be white with it due to the dust from the sawing...

It's all paranoia about it and in any case I've got to die of something.

 

It'll take them a week to cremate you.

 

They cremated George Best in Hemel Hempstead on Sunday.

Look what happened to him.
