SWMBO did the cutting and I did the fitting measuring etc, took us a morning and cost $180. It has made a difference already just need to get under the rest of the house not much room but needs doing no carpets. You could do under concrete I suppose if you had the Hulk to lift the slab for you	gary67 (56)
1109822	2010-06-13 20:29:00	Can they put insulation under a concrete floor ? :) Not after the fact, but you can get polystyrene blocks set into your concrete floor when it's being poured. expol.co.nz	somebody (208)
1109823	2010-06-13 20:50:00	And the point being what ?? Our own floor, is only wooden T&G, you can feel the cold coming up through it, and the persons place I was at was the same. After the Expol was put in (or under as the case being) the rooms were warmer, less heating was required as the place wasn't so cold. When I was doing the walls last year in our kitchen, and the skirting was off the the walls/floor, there was a noticeable draft - the Expol works well. :) :banana Just proves that you believe in the Frigoric theory, that cold is a fluid substance. There is all this frigoric under your house trying to come up through the floor, so it has to be stopped with Expol................. :clap	Terry Porritt (14)
1109824	2010-06-13 20:58:00	dunno, well we have some of what was accessible. EECA has the insulation discount - all people are eligible, if you have a csc card you get more %. we didn't remove carpets etc. our one was like under floor attic whatever that is called. limited area cos under the garage was not accessible, plus the prev owner converted most of the underfloor section into a split floor (master bedroom).

1109825	2010-06-13 20:58:00	We had insulation installed in a 1920's bungalow with T & G floors. We couldn't get the polystyrene strips through the access space, so had to use the foil type insulation - it has a Batts type of layer glued on top of the foil. We noticed a significant difference. Apart from the house being warmer, we no longer got that black layer that used to develop on the carpet where it met the walls. I would strongly recommend underfloor insulation for a wooden house on piles. I investigated our style of insulation for our daughter's house in WA, and it seems like it is no longer available in Oz - it isn't regarded as satisfactory from an insulation rating point of view. Not sure what the situation is here in NZ. Either get your insulation installed by an expert or be very careful you don't electrocute yourself!	John H (8)

In case you didn't understand what Terry was alluding to... heat transfer is a transfer of energy from a higher temperature to a lower temperature. It is incorrect to talk about cold being transferred since it is in reality, a loss of heat to a colder area, rather than a transfer of cold to a hotter area. His comments were tongue in cheek...	user (1404)
1109827	2010-06-13 22:52:00	Thanks for the replies to my question - especially the ones that are :thumbs: relevant. :rolleyes: I have now decided to go ahead with the underfloor insulation. We have a quote using Novafloor polyester R = 1.4, with a wool product R = 1.9 as an option. Expol does not have a licensed installer in our region and I have been told that Expol is not fireproof or environmentally safe. Our own floor, is only wooden T&G, you can feel the cold coming up through it OK guys, we can trash this comment but I know what wainuitech means by his comment. "Frigoric" is not scientific but it does feel like cold comes up through the floor.	Strommer (42)

I know they were tongue in cheek -- geeeeeees. The whole point being that when I had the skirting off there was one hell of a draft (cold air) blowing up from under the floor, between the joint of the floor and wall. SO saying that, the Expol will stop it, or at least cut it down. As gary mentioned -- cheaper to do it yourself than contractors if you are able. Trying to get the Mrs helping :lol: Great Tuis ad -- more like directing traffic from above.	wainuitech (129)
1109829	2010-06-13 23:06:00	Well, cold certainly comes up through the floor in my daughter's house in WA, whatever you call the scientific process! The floorboards are not tongue and groove - they are jarrah planks that were just butted up to each other . My son in law (who is a forester) reckons the floor was laid with green timber - as it has dried out over the past 100 or so years, gaps have opened up and you can see through the gaps to the ground . They are on a slope, and the front of the house is about a metre or more above the ground - open to the prevailing winds, which in the winter can be pretty fierce where they are . Fortunately, he is able to source an unending supply of free dry jarrah firewood and their firebox is designed to burn that wood . However, they are going to put in insulation to cut down on the draughts .	John H (8)
