Have worked for a guy who installs it. we did 65 houses, quite good product, as long as its installed correctly. You need a snug fit, a bit fiddly around plumbing, wires, used to take us 2-3 days to do a 90sq m house. We cut the product with a hotwire, so little mess, if you use a knife, saw it can get quite messy.

at the moment i'm reading that there is quite a debate over floor insulation. it seams there has been problems with condensation because the insulation is keeping the heat above the floor and the bottom of the joists are now cold. condensation is forming on the now cold joists causing mold and rot.
however most of it seams to be in usa, i don't know if its a problem in our climate. probably be fine for those down south where it tends to be drier. northland however might be a different ball game.

I put Expol under my house and am very happy with it.

I have just checked ours. It was installed 5 years ago. It's all as dry as a bone underneath. We have excellent ventilation as w are on a slow and he baseboards are 2.5m at one end.

what sort of wall is around the crawlspace?
a lot of the ones in the overseas examples all seam to be be concrete brick wall. underneath may not being warmed up during the day to drive off moisture. there seams to be very little nz info on it.

We have pine baseboards so lots of gaps.

We put Expol under our house (second place now) and have been really happy with it. If you have good space underneath you could do it yourself easily, we did. Comes in different widths so do your prep work before you buy and work out how much you need of each width ( often there are different gaps between the bearers especially in older homes) get the widths to fit your gaps. The shops are really good and sell them by the bag, but also individually in widths. they are like concertinas so can push/wiggle them in. You can also use tapes to staple to beams to ensure they do not come out. Make a huge difference to wooden floorboards and where there is a large cavity space under the house. Good luck
it really quick.

I am sure that it will insulate your house very well, however if your house ever caught fire, it is extremely combustable and the toxic fumes would kill anyone in seconds.I would much prefer Batts; or its eqivelant.

Expol is not a flamespread material,it will simply melt away,by the time the fire got to the subfloor you should be long gone,one way or another!

unless the fire starts under the house!
worse thing to use is batts. you don't want to use anything that can hold moisture.

really? Polystyren is not a flammable material. ok. I still would not have it in my home.

You may be confusing packaging with insulation,they are two different products.

ebygum has it right - to meet building code requirements, Expol is made with a flame retardant additive, meaning if you try lighting it on fire it will simply melt & not add to the fire at all.
