For the thermal and acoustic insulation of external and separating walls in timber frame and ‘warm roof’ construction.

Description

Crown FrameTherm Slab consists of a resilient, unfaced, non-combustible glass mineral wool slab.

  • Crown FrameTherm Slab 43 has a thermal conductivity of 0.043 W/mK
  • Crown FrameTherm Slab 38 has a thermal conductivity of 0.038 W/mK
  • Crown FrameTherm Slab 35 has a thermal conductivity of 0.035 W/mK.

Application

Crown FrameTherm Slab is for the thermal insulation of external walls and warm roofs in timber frame construction. Crown FrameTherm Slab is friction fitted between studs and rafters and are 570mm wide to suit commonly used stud and rafter spacings.

Crown FrameTherm Slab can also be used for acoustic insulation in timber framed separating walls.

Standards

Crown FrameTherm Slab is non-combustible inorganic glass wool, defined as mineral wool in BS 3533: 1981 and are manufactured in accordance with BSI Quality Assurance Standard BS EN ISO 9001: 2000

Vapour resistance and condensation

Crown FrameTherm Slab allows water vapour to pass freely through the insulation, therefore allowing the construction element to breathe.

Durability

Crown FrameTherm Slab is rot proof, does not sustain vermin and will not encourage the growth of fungi, mould or bacteria. Crown FrameTherm Slab is odourless and non-hygroscopic.
