Underfloor insulation
Pink Batts vs the polystyrene stuff.
Noticed that there is a layer of cold air at floor level, so looking at insulating underneath the house.
Wondered of anyone had an opinion on the types of insulation available?
However there is not much room underneath the house and going to have to do the whole job on my back.
How easy is it to install? Is it something that can be done quickly and is there much difference in the two different types, in terms of efficiency?
BTW it get around -4 on the coldest nights.
Cheers

This is what consumer.org reckon.
Our advice
For cost-effective insulation with reliable R values, you can't go past blanket fibreglass products. Fibreglass can be installed by DIYers, is readily available throughout the country and is relatively cheap. Pink Batts is the best-known brand, but others like Bradford Gold are worth checking.
Mineral wool is our pick of the loose fill insulation products. It has reliable R values, but it is not cheap.
If you want to install blanket-type insulation yourself, but don't like fibreglass, go for wool or polyester. They are more pleasant to handle and less prone to damage, but you will pay more.
Shop around. Prices vary widely and some great specials are available, especially at the end of winter.
Polystyrene can be fitted under existing floors as a DIY project.

It's a beauty today! Grab a beer at the Jolly Roger and have a gander at the boats for us!
Thanks for info, probably going to get the Expol polystyrene stuff.

Our exploits ended up as a separate blog entry - (snowing in Hamilton) not sure if that helps or not!!

Re: Underfloor insulation
The stuff we have is in big sheets and looks like bubble wrap between two layers of foil. It forms a moisture barrier as well as insulating and has made a huge difference to our house near floor level.

Re: Underfloor insulation
Beware if using polystyrene near electric cables, as our electrician says the two plastics interact and can cause problems as bad as fires if they react enough
