What is Isoboard?

IsoBoard is a rigid, high density, extruded polystyrene, manufactured in different thicknesses and lengths to meet almost any building thermal insulation requirement in the temperature range -30 to +60°C.

IsoBoard has Board of Agrément SA certification for five popular applications, which certify IsoBoard is fit for use as recommended. IsoBoard is without doubt the most versatile thermal insulator available.

Thermal insulation provides a barrier to heat transfer, which keeps heat energy on one side of the board or the other. Insulation does not, of itself, provide heating or cooling, but rather controls where heat energy should be, either inside or outside.

Advantages of IsoBoard

The advantages of IsoBoard are in its effectiveness as a thermal insulator, ease of installation, high compressive strength, resistance to moisture and excellent performance in fire situations. The board is extremely durable and will last for the life of the building, with minimal drop off in thermal performance.

IsoBoard can be painted with water based paints when used in exposed applications, and washed to clean if necessary.
