| 671872 | 2008-05-23 10:40:00 | Hi all, Has anyone installed Expol? I'm considering putting it in, and was wondering how well it works, how easy it is to install etc? Info on all other forms of underfloor insulation welcome too!! :thumbs: |

Only something like 5% of heat is lost through the floor, so you are better to insulate the walls and floor, and even use double glazing. They can pump insulation into the walls now, if you have an old timber house. |

| 671875 | 2008-05-23 20:07:00 | I've installed expol before, and found it ok to do. It can be a tiring and frustrating process if your house is relatively old, and the floor joists aren't necessarily evenly spaced. My house has more headroom under it than most houses do (between 600-1500mm of height), which made it a lot easier to crawl around and put it up. Expol comes with strips of brown paper with adhesive, which you use to protect power cables. |

| 671877 | 2008-05-23 23:59:00 | for only 5% loss is it worth the $$$. bit pointless saving 5% and losing 20% elsewhere. IMHO better off to just make sure under the house stays DRY. ie good drainage and some ventilation. with well sealed floorboards and especially with carpet you won't need extra insulation. |

Yes it is a waste of time . You are better to staple up perforatedl foil under the house, and install batts in the ceiling . It isn't actually that expensive to pump in insulation into the walls . Expol underfloor insulation however is a waste of money IMHO, especially as heat rises . |

And I have nothing under my floorboards. Most rooms have carpet but not all. I have old wooden window frames with a bit of a gap in one or two. I do have batts in the ceiling and some walls. And its warm, thanks. But I did live in a plastic wrapped house prior, aluminium windows etc etc, it was full of condensation all the time. |

It has made a HUGE difference with heating. Well worth it. |
