We're selling alot to Builders Merchants in bulk so I thought why not offer them to my loyal following at a decent price for a load. Now these are the rolls that are marked up as 100mm thick but in testing some only came up to 80mm thick hence the 80/100mm classification.Would do for internal partitions as they have some sound proofing they also split into .400 .600 and 1.200 widths.This is a bulk purchase of 24 rolls 1 pallet.Now some clever person has pointed out that if they want say 30 rolls they have to pay more for the extra 5 so if you order a bulk purchase on line and phone us for the extras we'll give them to you at the same price provided they go on the same delivery.
