ABSTRACT OF THE DISCLOSURE For applying a covering to mineral or glass fibre insulation batts, the batts are deposited in succession into a vertically elongate batt stacking space to form a stack of the batts, and upper and lower compression plates each having a concave compression surface the shape of which compression surfaces correspond at least substantially to the shapes of convex upper and lower surfaces of the package, are displaced vertically by an amount sufficient to compress the stack between the upper and lower compression surfaces with a compression ratio of 6:1 to 11:1. A covering of flexible sheet material is then provided around the compressed stack to maintain the stack in a compressed state. The concave compression surfaces make possible a higher compression of the batts than was possible with the flat compression plates used in the prior art, without damaging the batts and therefore while allowing satisfactory recovery of the batts when released from their compressed state.
