HI -TEMP PLASTERBOARD SCRIM TAPE 
Heat Resistant Glass Fibre Plasterboard Scrim Tape is for use in conjunction with Vitcas Heat Resistant Plaster. The fibreglass self-adhesive tape is for joints and internal corners between plasterboards. The joints have a tendency to crack so they need to be taped and plastered over to secure it.  

Heat resistant scrim tape (self adhesive tape) is for the joints in high temperature plasterboards. The tape should be applied first onto the joints of the plasterboard and then it should be plastered over using a skimming plaster such as Vitcas Heat Resistant Plaster. This maximises performance.
Benefits:
prevents cracking between the plasterboards
self-adhesive so easy to use
resistant to high temperatures
Applications:
for preventing cracks in joints and internal corners of plasterboards
