Underfloor insulation. A question for builders, diy'ers or insulation freaks.

hi guys just a quick update.

have finished this, used the rockwool, (£8 for the big rolls from b and q. 200mm thick - bargain). Netting was a bit tricky at first but theres definitely a knack to it. All in all a straight forward job. Hardest part was getting the floorboards up, ended up replacing them with t&g chipboard which was a doddle to lay and provides a nice snug fit. Not sure if its made any difference yet but it was a rare chance to get it done as i was taking the kitchen out. If anyone wants advice feel free to pm me.

Here endeth my dullest post ever on cc. (and i dont make that claim lightly!)

T&G chipboard? Oh dear. Hope you don't regret that next time you have a bit of water around and it turns to wet shredded wheat. Our dishwasher broke on Saturday and flooded the kitchen, water got between the chipboard and the vapour barrier above the insulation, now the board has swollen underneath and pushed some corners up so we keep treading on them through the nasty carpet that we inherited with the house. Not worried though because it's all going as soon as we can find the cash to do the kitchen.

Isn't this K glass? It has a slight mirror to it, which makes it more reflective.

I specified Pilkington K glass with Argon fill on some replacement double glazing for units which had failed. I have no numbers, but I can say that none of the replacement glass gets condensation in this cold weather, whereas the standard, original double glazing does.

IMVHO, I think that that is probably down to the standard of workmanship. Sealed units with low-emissivity coatings and gas fill tend to be made in specialised factories with good quality control whereas a standand unit can be knocked up by the local glass merchant.

I could be wrong.
