Customer Questions
For the RW3 100mm, how many packs do I need for 10m2?
The 100mm Rockwool RW3 is supplied in packs of 4 slabs which cover 2.88m2 in total, therefore to cover 10m2 you would need 4 packs.
I need to order a lot of packs, how should these be stored until the builder is able to use them?
The packs are delivered in a polythene wrapper which provides temporary protection from the elements. For longer term storage, Rockwool should be kept inside if possible, otherwise stored undercover and off the ground.
Should I be using Rockwool in my walls or a product such as Celotex?
The best product to use will depend on where it is to be used and what the situation is. Both Rockwool products and Celotex provide good thermal insulation, however if it is solely thermal which is required then Celotex may be the better option, as it has a better thermal performance. However Rockwool products have much better sound-absorbing and fire-resistant properties.
