COVERAGE RATE

TORCHING GUIDELINES
The underside of the membrane should be torched just enough to superficially melt the bitumen. Excessive heating may damage the reinforcement. Overlaps should be re-heated from the top and resealed with a trowel to ensure seam integrity.

For details of installation methods and flashing requirements, consult the relevant BITUMAT Design and Installation Manual.

FINISHES
PREMIERFLEX 4000  is available in two basic finishes:
- Black smooth finish with polyethylene surfaces for covered applications.
- Granule surfacing for exposed applications.

QUALITY CONTROL
In addition to stringent regular tests by BITUMAT laboratory, our products are tested periodically by Bureau Veritas & SOCOTEC, Paris, France.
