I am getting priced up for 200mm EPS and looking at the difference in U-values. It seems that the computer says 200mm on 500mm stone/rubble walls with fixings gets me 0.17 for ordinary and 0.14 for platinum. The platinum will be significantly more expensive. I think the wall u-value underestimates the performance of the rubble walls but won't be able to work out by how much. What should I be aiming for (I know 0.0 would be good!). I think 200mm is as thick as is practical.
Also there is a density issue. Some of you will have seen my 'floating eaves' detail where the eaves are supported by the counterbatens. I was thinking of using higher density EPS in this area (100 rather than standard 70). Do you guys have any views?

Thanks
Paddy

Sounds like not a massive difference in your prices and would get me down to U= 0.14. Is this an aceptable U-value? It would be nice to not require the radiators (i have four large ones in my living room!). As discussed in previous threads I will be making air tight, reducing thermal bridges to rediculous levels, putting in wing insulation at foundations a nd adjusting my windows in a DIY bodge.

A few years ago I ordered lots of block paving from jewsons and almost jokingly asked if they could beat their trade discount for the larger volume - the girl on the counter showed me to the managers office and they knocked a further 50% off!]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=7159&Focus=105947#Comment_105947 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=7159&Focus=105947#Comment_105947 Tue, 22 Mar 2011 12:03:22 +0000 DamonHD

I don't know where you are in the world, but...
If you are ordering 'big' quantities of insulation, get the BMs to contact the Sales Rep/Area Manager of the manufacturer and get their 'best' price. I have managed to get 25% off with one phone call.

Good luck....]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=7159&Focus=106294#Comment_106294 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=7159&Focus=106294#Comment_106294 Fri, 25 Mar 2011 21:43:25 +0000 fostertom Posted By: jamesingramAlso ex VATBut only 5% - incl all consequent work - realy v liberal.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=7159&Focus=107769#Comment_107769 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=7159&Focus=107769#Comment_107769 Fri, 15 Apr 2011 11:09:24 +0100 pmagowan http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=7159&Focus=107788#Comment_107788 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=7159&Focus=107788#Comment_107788 Fri, 15 Apr 2011 17:25:10 +0100 Saint Posted By: pmagowanMy prices are through at £94.50m3 for EPS70 plat and £62.5m3 EPS70 white.
