Thanks Superman,
I will be building in north so dont think Homebond will affect me. I must check with NHBC etc. Also, Engineer looking at this at minute.
Sydthebeat,
i have also looked at the external insulation systems and am not overly keen on them. I just dont like idea of having 300mm of insulation outside the building, durability issues mainly i.e. impact from football etc. Another issue with these is the cost - i have approx 340 m2 external wall.
Why would you not consider beads for new build?
Regards,
