Roof Thermal Insulation

Isoboard Properties

lsoBoard, high-density extruded polystyrene rigid thermal insulation board, having 100% closed cell structure! Determination of physical properties of lsoBoard rigid foam insulation, dated July 1996, by the Division of Building Technology of the CSIR.

Under Soffit Ceilings

Where construction, design and / or cost implications prohibit the installation of an inverted roof insulation system, the requirement for insulation is met by fixing IsoBoard to the under soffit surface of the slab as a ceiling.

Roof Insulation from A-Z

D&D Roof Insulations supplies roof insulation materials fit for large-format steel roof structures with steel cladding, roof sheeting, side cladding and more

Over Purlin Insulation

IsoBoard Insulation installed over purlin under roof sheet. — In South Africa, the bulk of retail and industrial buildings are steel-sheet clad frames, where 70% of the heat gain is through the roof. IsoBoard over purlin insulation is the most cost effective method of achieving thermal efficiency in these buildings.
