US: Johns Manville (JM), a Berkshire Hathaway company, has launched JM Spider® Plus blow-in insulation, a re-engineered blow-in system. JM Spider Plus replaces JM Spider spray-in fibreglass insulation and JM said that it is ideal for residential, commercial and manufactured buildings.
JM Spider Plus is designed for installation by professionals using a blowing wool machine and features 'Interlocking Fibre Technology,' a new innovation from JM. Interlocking Fibre Technology allows the insulation fibres to spring and lock into cavities with no adhesive or netting. JM Spider Plus achieves an R-value of 15 in a 2x4 cavity and an R-23 in 2x6 walls.
JM Spider Plus is available to customers in North America immediately.
