Height and thickness are all approx. 92cm x 5cm. Purchased in 2016. Used in a self-made soundproof room, but being sold due to current dismantling. It's hard and sturdy, so it's also suitable for floor construction (of course, it can be used for other purposes as well). It will be wrapped in a plastic bag for waterproofing and shipped in a reused cardboard box. It's already packed, so it can be shipped immediately ☺︎ Shipping costs 2200 yen, so please refrain from requesting a price reduction. *I also sell other rockwool products.
