Isover Spacesaver Roll is a high quality glass mineral wool insulation in roll form for thermal application in cold roof and loft floors. Rolls are pre-perforated at 3 x 386mm and 2 x 580mm to allow easy installation between joist centres of 400mm or 600mm.
On rare occasions we may need to substitute 12 rolls of Isover Loft Insulation for 9 rolls of Knauf Insulation. Knauf rolls are larger so you would receive 2.67m² less and for this I would refund £5.00 (125.01m² instead of 127.68m²) I would confirm with you that this is acceptable beforehand. Both are the same insulation value.
Isover Spacesaver provides thermal insulation for cold roof constructions in both new-build and renovation projects. Rolls are installed in two layers, the first layer between the joists and the second layer cross laid over the joists.
