I'm wanting some boards to make corner chunk traps. Made some low density ones from isotherm but they were pretty unscientific and don't do a lot.
Thinking of three corner chunk traps 3m high... so with 50mm panels that would be 45 boards.
I was planning a group buy a year or so back but Jay at Egoli was just so ludicrously unresponsive that I gave up and went on to other things.
I think his unresponsiveness is based on 1) we buy little compared to what someone doing their roof would, 2)they don't often have stock of the not so common for roof use, high density boards.
I know when I got mine last year, no one mentioned in this thread had stock of what I was looking for - had to wait 3 weeks for the next run from isover since they do batches of different product every so often (usually long after national stock is sold out).
