AI Technical Summary
Existing fire protection solutions for sealing openings in walls or ceilings, such as those containing pipes or cables, are expensive, require significant installation space, and fail to seal effectively at low activation temperatures, particularly with low-melting-point materials.
A fire protection element with a band-shaped support and tongues made from bimetallic material that moves towards the opening at slightly elevated temperatures, applying a fire-resistant material to actively close the gap and reduce heat transmission, using a substantial portion of bimetallic tongues coated with intumescent materials.
The solution provides a cost-effective, compact, and early closure of openings during fires, effectively sealing combustible materials by activating at lower temperatures and reducing heat radiation, using a bimetallic design with intumescent coatings.
