The 2 part epoxy kind.
I think spookyb829 used it on his van. Anyone else used it for owt?
My dad suggested it for my concrete sectional garage as a much easier /quicker/cheaper way to insulate my concrete sectional garage -non asbestos fibre board roof.
Needs insulated as I'm planning to use it for turbo and working out . It's getting a set of solid doors on the front so it won't be like insulating a fridge but currently hard efforts in winter results in it raining from the roof when my sweat condenses on the cold roof.
Likewise after sunny days and cold nights it's often already condensed on the roof.
I'd not considered spray foam -i was gonna use seconds and co kingspan but then I lose both width and height and I can't really afford either + even using seconds and co it still works out pricy
Plan would be to leave roof as sprayed and. Ian/paint the walls after foam.
Thoughts or suggestions ?
Hi, yes I used it on my first van, but didn't bother on my second. It really excels where you have curved walls as although its expensive, it saves lots of time as long as you prep really well.
Obviously in a garage there is a lot less prep involved. The standard small kit only just managed to do my van (3.6m load length) so check carefully, if you need a second kit that makes it a lot more pricey.
You could also check non-DIY prices, the guys that do warehouses will have a large tank setup in a van and will be able to put as much depth in as you want, with much less chance of clogging nozzles (very easy to get an uneven mix, and then the foam either stays soggy, or does not expand properly.
If you have natural daylight in your garage, you may find the foam discolours to a dark orange, so would need overboarding or perhaps painting would protect it from UV.
Inside my garage has lots of profiles that will mean lots of voids using kingspan which was where the idea of using the foam came from.
My only experiance is of removing it from sarking after some cowboys talked a relitive into having their wooden roof interior sprayed and then rot set in as it doesn't breath.
Concrete and fibre board obviously not going to have that issue- or at least not to the same extent.
Where did you get it from - I was seeing costs of about ,400 quid per 60sqm.
Good shout on getting prices from a man.
Times getting short on supply and winters coming.
This an ex workmate doing this now.
I can't remember the brand but yes, it was one of the £400 kits...two small keg sized cylinders. Can't comment too much on coverage as I don't think it expanded as much as it should, and I had still had some liquid sloshing in one cylinder when the other ran dry!
