Permastop® Building Blanket

Permastop is a high quality insulation blanket that features excellent thermal and acoustic performance. Made of glasswool and faced on one side with sisalation reflective foil laminate that is non-permeable to moisture. It has a 150mm foil lap on one side to allow the moisture barrier to be sealed. Permastop is able to be supplied with a wide range of Sisalation facings. Permastop blankets provide condensation control under metal deck roofs, behind wall cladding, and under concrete roof structures to reduce heat loads entering a building. Permastop also provides and excellent solution for acoustic treatments of metal clad buildings by reducing internal reverberation and unwanted noise created by rain, hail and the expansion and contraction of metal roofing and cladding.  It is manufactured by Fletcher Insulation and comes in the following R-Ratings and thicknesses:

  • R1.3 55mm Permastop® 
  • R1.8 75mm Permastop® 
  • R2.5 100mm Permastop® 
  • R3.0 130mm Permastop® 
  • R3.5 130mm Permastop®

DOW Tuff-R™

Polyisocyanurate PIR Rigid Thermal Insulation

Featuring the highest thermal insulation value of any foam sheathing current-ly available, Dow Tuff-R™ distributed by DCTech is a closed cell polyisocy-anurate (PIR) foam core sandwiched between two durable, aluminium foil exterior facers. The first is a continuous sheet of aluminium foil, the other is aluminium foil-Kraft paper-aluminium foil. Air cannot penetrate the facers, which also minimises water and water vapour intrusion into the polyisocy-anurate foam insulation core, and allows the foam R-value to stabilise at a higher value. Dow Tuff-R™ thermal insulation can be easily applied to a variety of substrates.

  • High R-Value enhances thermal efficiency
  • Facers help reduce are penetration and water vapour intrusion
  • Compatible with most exterior siding treatments
  • Easy to handle, cut and install
  • 15 Year limited thermal warranty
  • Green Star Compliant
  • CFC and HCFC Free
  • Zero ODP
  • LEED
