IsoBoard thermal insulation is a high density, extruded polystyrene rigid insulation board, having a 100% closed-cell structure. IsoBoard has been tried and tested internationally since 1970, and manufactured in South Africa since 1995, using a fully automated extrusion process, in accordance with international specifications and standards.
IsoBoard is one of the very few manufacturers to present AGED performance values for our products. All insulation materials deteriorate over time, due principally to the effects of weathering and moisture, although these have minimal effect on IsoBoard’s thermal performance.
Heat gain in residential homes is largely through the roof structure. Insulated ceilings retard heat flow into the living areas in summer, and contain generated heat in winter, providing a comfortable living environment.
Cavity wall insulation will prevent heat transfer and build-up to the inner leaf of sun-exposed walls. Moisture within the cavity is prevented from condensing onto and penetrating through the inner leaf when IsoBoard is installed.
Loss of heat through floors on concrete surface beds is experienced as a cold underfoot condition, particularly during winter when the supporting soils cool down due to hygroscopic action of water.
IsoBoard can be used to thermally insulate many existing buildings which require upgrading with respect to comfort levels or energy efficiency. IsoBoard is suitable to be installed as a ceiling, either beneath an existing ceiling, or between trusses or rafters.
EASE OF USE
The tongue and groove edge profiles allow adjacent boards to interlock, creating a continuous insulated surface. Boards are available in standard lengths and thicknesses to fit most applications. Installation is easily accomplished by both professionals and DIY enthusiasts. The lightweight nature of IsoBoard means installation proceeds quickly.
IsoBoard is proven in fire situations, both through laboratory testing as well as actual fire events. IsoBoard shrinks away from flame sources, with no flaming droplets or flame spread characteristics.
IsoBoard can be employed to meet almost every building envelope thermal insulation requirement.
IsoBoard has a bright white surface, which can be easily painted and stained with water based products. The “Isopine” option has 100mm centre grooves routed down the length of each board to imitate a T&G wood panel effect. Unpainted board can be wiped clean as necessary. Boards damaged during installation can be repaired with adhesive or filler products prior to painting
RESISTANCE TO MOISTURE TRANSFER
IsoBoard is not materially affected by water vapour or water, and can be successfully used in bathrooms, kitchens and indoor swimming pools.
