  • Insulates against cold
  • Good thermal performance
  • Breathable – allowing moisture to pass through
  • Prevents condensation build-up
  • Lightweight and easy to handle
  • Made from re-cycled materials

PRODUCTS With an impressive thermal conductivity value (k) of 0.05 W/mK, Bitroc delivers insulation performance up to SIX TIMES better than conventional sheathing boards. The use of Bitroc as sheathing allows for reduction of wall insulation depth and reduces the requirement for high density and more costly insulation materials. 

PERFORMANCE Bitroc´s performance is further enhanced by its ability to resist racking, water ingress and its ability to breathe. Also Bitroc´s properties prevents cold bridging through the timber or metal stud-work. Bitroc is lightweight, easy to handle and cut. Hunton Bitroc does not require a breather membrane, except in extreme situations.

INSTALLATION AND FIXING

Hunton Bitroc is included in the list of materials suitable for timber frame sheathing, as described in BS5268.For racking, timber studs should be 38mm or greater, stud centres should not exceed 600mm and the boards fixed using 50x2.9mm nails as a minimum. To satisfy NHBC approval, joints between Bitroc boards should be made over a frame stud to prevent direct passage of moisture into the structure. Panel to panel joints should also be protected by use of a strip of breather membrane fixed to one edge of the panel and lapped over the face of the adjacent panel. Alternatively, a gun applied mastic sealant is acceptable to seal the panel joint. Vertical battens which form part of a cladding system can also be fixed tightly over the panel joints

Hunton Bitroc can also be used as a sheathing for lightweight steel framing and be fixed using dry wall or self tapping screws. Fixing centres should be specified by the structural engineer; however, 150mm on the perimeter and 300mm internally is recommended.
