Advantages

Thermally Efficient: Effective resistance to heat transfer, with RSI/R-values up to RSI 4.9 (R-28) for wood stud and RSI 7.0 (R-50) for metal stud.
Formaldehyde-free: Will not off-gas formaldehyde in the indoor environment.
Sound Control: Reduces sound transmission through exterior and interior walls, floor and ceiling assemblies.
Fire-Resistant: Flame Spread of 10 or less and Smoke Developed of 50 or less.
Resilient Inorganic Glass: No rotting, mildew or deterioration. Also noncorrosive to pipes, wiring and metal studs.
Superior Performance: Stable bonded glass fibres will not slump within the wall cavity, settle or break down during normal applications.
