SEALz® VTape is a flame-resistant and thermally insulating ceramic fiber tape ideal for sealing gaps in fire-rated doors or other passive fire-protection systems.

It is highly stable against heat and flame and will not shrink or degrade in a fire, thus reliably preventing heat and flame from penetrating gaps in your fire-rated doors. It is also moisture resistant and resistant to atmospheric degradation. SEALz® VTape is ideal for situations where high expansion or pressure is undesirable, such as around the vision panels in doors. It is available in no-expansion as well as low-expansion formulations, with the low-expansion formulation having an expansion ratio of approx. 2-3x at 600ºC.
