Class O is a lightweight, closed cell flexible insulation foam for reliable and continuous condensation control.
It has a unique micro-cell structure (Armacell grade) that makes the foam easy to install with no additional vapour barrier requirements. This material is tested to BS476 part 7 and achieves results better than class 1.
A combination of low thermal conductivity and high resistance to water vapour prevents long term energy loss, moisture ingress and reduces the risk of corrosion under insulation.
The built in Microban protection and excellent fire performance make Class O suitable for use in public buildings and process industries.
The Armacell grade of Class O is dust, fibre, and formaldehyde free.
Typical applications include pipework, air conditioning ductwork, hot and cold-water services, and insulation/protection against condensation.
