I have a lot of clean, insulating, lightweight foam which lined frozen food boxes. It could be used to make DIY cool boxes for the summer, for insulating against the cold, or for ebay packaging. It's quite a firm foam (not soft like a sponge, more of a plastic foam) and can easily be cut with scissors. It's flexible and easy to clean.
It's 1.2 cm thick and the largest pieces are 47 cm x 62 cm.
I have three large bags full. Happy to split if you don't need it all.
