Fire protection insulation ISO-B1

Fire protection insulation ISO-B1

If we are talking about safety in the boiler room there is no alternative to our brand new insulation „ISO-B1®“.

Our fire protection insulation „ISO B1“ guarantees perfect insulation quality. In accordance with DIN 4102-1: 1998-05 the insulation is difficult to ignite. The water-repellent characteristics of the fire protection insulation enable the application of an additional bottom insulation (included in scope of delivery) which guarantees an even better protection from heat loss.
The fire protection insulation ISO-B1 is available with extra charge for our stratification buffer tanks SLS, HSK-SLS and HSK-OEKO.
