Isover Orstech LSP 40

Lamella mat Isover Orstech LSP 40 can be used universally for HVAC applications with lower service temperatures. It is suitable especially for air ducts. Despite the fact that hydrophobing additives in the insulation impede the ingress of water, it is necessary to protect lamella mat in the construction against moisture and possible mechanical damage by a proper manner. 

Isover Orstech LSP 40 has a maximum service temperature of 250 °C according to EN 14706. Surface temperature on the aluminium side must not exceed 100 °C; proper thickness of insulation must be designed to fulfil that. Binders and greasing agents in mineral wool products dissolve and evaporate in areas with temperatures > 150 °C. In the outer, colder areas, no dissolution and evaporation take place.
