- Thermally efficient - provides effective resistance to heat transfer with R-values upto R-49 (RSI-8.6)
- Sound control - reduces transmission of sound through exterior and interior walls and floor or ceiling assemblies
- Durable inorganic glass - will not rot, mildew or deteriorate and is non-corrosive to pipes, wiring and metal studs
- Superior
performance - bonded glass fibers are dimensionally stable and will not
slump within the wall cavity, settle or break down during normal
applications
