Chaps where are you guys getting your blue foam from for wing cores ?

the last lot of wings I made I used the white foam from wickes  

any suggestions even if it’s pink or orange

Msybe consider black EPO (expanded polyolefine or something like that)? Soar-Ahead-Sailplanes' combat wings use it. Cut well and durable from the kits I've built

Do you care about the weight? I bought some of the black stuff, and it was twice as heavy as the Wickes insulation boards.

Yeah weight is paramount. 
The wings are going to be four meters

I don’t know much about this, but I’m guessing that manufacturers colour code different densities. Certainly the black stuff I’ve still got quite a lot of is heavy at 49g/m3. Genuine Styrofoam comes in a variety of weights, and can be 2/3 lighter than my black stuff.

That link certainly looks like the correct stuff but in the description it specifically says "not suitable for crafting/model making."  So I assume (dangerous I know) that it might give off nasty fumes when hot wiring.  Also there is a minimum order of 5 sheets which means the cost is £77, but at least its free postage.
