    Home Insulation

    Wanting to insulate the underfloor of the house, has anyone had anything to do with this product http://www.knaufinsulation.co.nz/sit...e%20LR22_0.pdf and can shed some unbiased light on it. I was interested in the 75mm stuff with the black backing on it! Alternately, if someone can recommend a good underfloor insulation for wooden floor boards? Thanks.

    we have "dacron" works ok but i would look at other stuff too. biggest difference was made by the black plastic sheet over the soil. the amount of moisture that the dehumidifier pulled out of the air dropped by 50%.
    and turn off the f..ing DVS !! biggest con in the land

    http://www.eliteinsulation.co.nz/sho...-PpRoCm1fw_wcB
    Has made a fair difference to my place with wooden floor boards.
    Not sure on the retail cost as I had it done by a friend of a friend as a perk.

    Following, have 20+ year old shines tar paper stapled to the underside of the joists. Was thinking expol or similar.

    When there is often a foot of snow on the ground for a month or more you sure chew through the wood so waning as much insulation in as I can

    We used to live in a 2 bed flat at work, we always had cold feet until we had polystyrene under floor insulation put in. The first night we noticed we didn't have cold feet, it made a real difference. It was about 80 mm thick and jammed between the floor joists. Well worth it.

    Thanks for the info guys, good testimonials. I know nothing of insulation really, and I was just wanting to do an install in the rental, however, at the right price, and if I DIM (do it myself) I'm hoping I may almost be able to do two houses for nearly the price of one (mine and the rental). I was warned off EXPOL (my favorite choice) as I was told that your floor joists may not be parallel, and therefore can get gaps along the side??? Also it was a lot more expensive than the one I was looking at. Nice website clickbang, that insulation looks good also.

    Yep My house was probably 1/4 done with expol. I ripped it all out and used the green stuff in the link in my previous post

    I've not used the underfloor stuff but have used there product in my loft space.
    It's works a treat.
    Might have to look at putting this under the house as well thanks.

    I do have a question to this though?
    So my home is raised. Can I attach the insulation to the concert slab?

    http://blog.kingspaninsulation.ie/wp...ete-Floors.png I'd be attachingit to the very under side of this image.
    Thanks for any replys.

    Dad got his 70 year old house done. The under floor dried out so much the floor started creaking when you walked on it. Couldn't punch it because of the carpet so I pulled up the polythene it's quiet now but it's taken about 5 years to settle.

    What did your father originally get done, lay a damp course of polythene on the ground, did he?

    It's reasonably cheap, and I do like the black wind wash backing on it. Might go that in the rental, and the green in my own home?

    Yes one gang cleaned the ground the next did the damp course and the next fitted the batts between the joists. He asked about it but couldn't get any sense out of anyone.
