Depending on the number crunching, I seem to be settling on a 155mm full fill cavity with eps beads for a number of reasons, fast install, builder free installation etc to name a few.
With Thermabead's Carbon Saver for example brick outer, 155mm full fill, med dense block inner and plaster finish gives back a u-value of .18.
To cost out Thermabead have said to work on the basis of £10pm/sq for a 155mm fill.
I was just wondering if anybody had there insulation costs to hand to easily try and draw some comparisons to other methods (I realise this may difficult so cost per meter squ would be easiest)
If anybody can suggest other eps bead providers also. Finally, would like to hear people's options on the figures achieved above. I like it as it appears a respectable value for a modest cavity size.
Climabead doesn't seem to perform as well (185mm needed to achieve the same), waiting to hear back from Poly-pearl and energystore (all taken from the national bead blowers association website)
thanks in advance
