ecowise VS polypearl comparison enquiry

[daithi]

Hi folks-I have been quoted 2 differing figures by 2 glaway based insulation companies for cavity wall insulation-ecowise (who use certainfil27 graphite thermal bead)quoted me ca E1450 while polypearl (who use the ordinary stuff) quoted me over E2000 for the same job.I'm wondering has anybody out there had experiences with either or both companies?? Thanks in advance,

I used polypearl and had no issues but that is not necessarily a recommendation for them over Ecowise as I didn't get any other quotes.

The important issue (other than cost) is the difference in the thermal insulation that one might provide over the other one. Both companies should be able to tell you the final U-value of your wall construction after they have filled your cavity with their product.

I would say go with the best (lowest) U-value even if it is a bit dearer. If the values are very close to each other then I gues € 600 is a fairly big difference.
