The insulated product variants comply with the fire-safety requirements for insulation, according to DS 428, and, on the basis of DS 428, fire-safety tests have been carried out on non-insulated product variants.

The uninsulated product variants come with a condensation safeguard which reduces the risk of condensation forming due to moist ventilation air.
