Transcription of IsoBoard, high-density extruded polystyrene rigid …
1 isoboard , high - density extruded polystyrene rigid thermal insulation board, having 100% closed cell structure!PROPERTIESP hysical Properties of IsoBoard1. Determination of physical properties of isoboard rigid foam insulation , dated July 1996, by the Division of Building Technolog y of the CSIR2. Copies of test reports are available from Isofoam (South Africa) (Pty) Limited upon request, or on our thermal conductivity reports by the general physical laboratory of the South African Bureau by Standards num-bered 722/82397 /NK9, 10, confirmed by Guarded HB tests February isoboard is combustible, with no flame spread char-acteristics.
2 isoboard is suitable for all occupancy types in horizontal and vertical applications, except for build-ings where non-combustible materials are prescribed by SANS 10400XA. (Reports on the fire propagation proper-ties of isoboard dated July 1996, by the Division of Building Technolog y of the CSIR, and further assessments by Firelab to SANS 428 dated July 2007.)5. The compressive strength and density of isoboard increase with thickness of boards. thermal conductivity is constant across the density Sample board immersed in water to 50 mm depth for 24 hours.
