LPD Brown Fire Only Intumescent Strip INTRUBFD

This brown fire only intumescent strip is built for one job, and it does it well. When heat rises during a fire, the intumescent material expands, sealing the critical gaps between the fire door and the door frame. That expansion helps slow the spread of fire and protects the integrity of the fire compartment. No noise, no moving parts, just smart passive fire protection doing its work when it matters most.Designed to sit neatly within a rebated door edge or frame, the brown finish blends in naturally with timber doors. It stays hidden during daily use and only activates under high fire temperatures. This makes it ideal for projects where fire safety compliance is required without changing the door’s appearance.The strip is fire only, meaning it focuses purely on heat expansion and does not include a smoke seal. It is commonly used in residential, commercial, and HMO fire doors where tested fire resistance is the main requirement. Each strip is manufactured to meet industry fire test standards, giving installers, inspectors, and property owners confidence. Reliable, discreet, and built for performance, this intumescent strip is a practical choice for maintaining fire door safety, meeting building regulations, and protecting people and property when every second counts.
