In order to keep pricing as competitive as possible, and reduce any chance of damage during shipment, Earthwool® glasswool cannot be ordered in individual packs, and the area calculator will automatically round this up to the nearest MasterBag. MasterBags typically contain 4, 5, 6 or 8 packs depending on the product. If you have excess ceiling product left, we recommend that you add a double layer firstly over the bedrooms and then living areas to maximise the comfort of the home. Wall products can also be installed in Ceilings, however Ceiling products should not be installed in walls.
