SHERPA Fire Stop 2.5 is a graphite based intumescent seal with a starting temperature of approx. 150°C (302°F) designed to protect SHERPA connector assemblies from the impact of accidental fire events.
- High-impact and resistant to aging
- Resistant to humidity influences
- Free of organic solvents
- Paintable (Preliminary tests absolutely necessary)
Specifically, Sherpa can guarantee fire resistance R30 (single layer) and R60 (double layer) for the concealed and visible connection variant. The Fire Stop 2.5 is used in one or two layers for the visible, screwed-on connection. The fire protection laminate swells at 150°C and protects the aluminum of the connector plates from direct exposure to high temperatures.
If the connection is milled into the main or secondary beam, the joint width may be up to 5 mm without additional protective measures being required.
The fire protection laminate is applied to the wood surface around the SHERPA connector and swells at 150°C.
length 25 m, width 20 mm, thickness 2,5 mm
