Browse Forums Heating, Cooling & Insulation 1 May 18, 2011 10:14 am We are currently renovating our laundry which is an add-on done in the 1970s. It gets very cold in the laundry and so we are thinking of buying some sheets of polystyrene to nail to the underside of our flooboards (our house is on stumps and has timber floor boards) and possibly put some polystyrene in the walls as well. Has anyone ever done this? And was it worthwhile putting it in? You can view the polystyrene sheets that I am talking about here: http://buybuildingsupplies.com.au/polystyrene-sheets-foam-sheets-c-22_2580_2581.html Also, the pipes that lead from our hot water system into our kitchen are on the outside of the wall and the previous owners wrapped rags around it to keep them from becoming frozen in winter. The rags are gross and it looks ghetto and I was wondering if we could remove the rags and replace them with this polystyrene foam tubing? http://www.foamsales.com.au/shop/p-pipe-insulation.html Again, has anyone used this stuff before on exposed pipes? Many thanks in advance.

I ain't sure if it would be suitable for you but it is probably worth having a look. Below is just one of the company making it for example: http://www.alucobond.com.au/files/9NY0F ... lowres.pdf Re: Polystyrene insulation 4May 18, 2011 6:02 pm Hi I have used this product. The aluminium improves the performance and protects the polystyrene. The printed grid pattern also makes it easier to cut correctly. The Harder You Try - the Luckier You Get !

Re: Polystyrene insulation 5May 19, 2011 10:19 am I saw that alubond fascia product on TV recently (perhaps Grand Designs or something like that). That particular product that you provided the link for, its main purpose is for external application on new buildings, I think. It looks too schmick and too expensive to nail to the underside of floorboards. What I am thinking of is something relatively cheap and chearful and somewhat effective for blocking out some draft that comes up from the floor and through the floor boards. Something like expol underfloor insulation or a type of polystyrene insulation.

Here it is http://www.foilboard.com.au/ A little more expensive than plain polystyrene but IMHO worth it. The Harder You Try - the Luckier You Get !

Quick, fairly easy, and effective. However not sure if it will pass a true fire rating, may need to be covered with some sarky. Still not too difficult. The lagging on the hot water pipes was the norm. yes you can use foams to cover the pipes not sure about the one you mentioned, need to check temp rating and whether UV stablised; it almost always will need replacing if facing the sun, in time. Maybe box it in some how, cover it in some way for the aesthetics with insulation on the inside. Good luck Pulpo Re: Polystyrene insulation 9May 21, 2011 1:08 pm Hey Sarah, I just spent the better part of last week under the house fitting the expol polystyrene sheets to the underside of our floor. We couldn't be happier with the results. They are really easy to fit, we have no more cold drafts coming up through the gaps between boards, and the flooring (old cypress) stays a comfortable temperature due to the air pocket the insulation provides. Where we used to have the heater on all night till bed, now we have it on for maybe an hour at most and the whole house stays warm, and this is in a 60's fibro dump with no insulation in the walls or ceiling! Highly recommended! Hey guys building a new place through a volume builder and just wondering if i should complain to the site supervisor as we just had plasterboard installed. Looks like… 0 11315 1000000% definitely add insulation. I have in my home and it makes a big difference minimising sound transfer. Insulation is pretty cheap and definitely worth it 2 6256 |
