Insulation nails are used together with insulation boards such as rock wool, glass wool and XPS boards. Correct installation ensures the board is firmly fixed and does not fall off during wind load. Drill holes on the wall or roof first with an electric hammer. The hole depth should be slightly deeper than the nail length, and the diameter should match the nail body. Clean the dust in the hole...
