The NIE BSB 90 fire protection block from Niedax is a highly developed product specifically designed for fire protection in electrical installations. This permanently elastic, largely closed-cell foam forms an effective insulating layer when exposed to heat, helping to prevent the spread of fire and smoke. The fire protection block is ideal for use in smoke-tight rectangular cable seals in fire protection sections, particularly in sensitive environments that are sensitive to dust, fibers, and moisture. It meets the requirements of fire resistance class S 90 and is approved for fire protection sealing of cable penetrations in walls and ceilings according to DIN 4102 Part 9. When applying, the technical specifications of the general building approval must be observed to ensure the safety and effectiveness of the product.
