- Permitted loads under exposure to fire R30; R60; R90; R120
- Tested fire resistance
- When attaching soft insulation materials that are not self-supporting, the insulation washer is simply pushed onto the insulation dowel
- Two-part design for fast, secure assembly
- Knock-in shaft has the design of a clamping sleeve and braces along the entire installation depth in the drill hole
- Anchor head surface is suitable as plaster base
The insulation panels must be fastened with at least 4 anchors per square metre.
Datasheets(X)
With a German construction permit, the anchor may be used in a multiple attachment configuration to anchor insulation panels in cracked and non-cracked standard concrete with a strength class of at least C20/25 and max. C50/60.
