PREMIERFLEX 4000

DESCRIPTION
PREMIERFLEX 4000 is an SBS modified bituminous waterproofing membrane reinforced with spun-bond polyester fabric. the combination gives the proven waterproofing qualities of bitumen combined elasticity excellent resistance to weathering and ease of application.

USES
PREMIERFLEX 4000 is a general purpose waterproofing membrane and is excellent in single layer roofing systems or as part of a multi-layer system. When surfaced with granular slates PREMIERFLEX 4000 is ideal as an exposed top layer.

OUTSTANDING FEATURES
· Excellent cold weather resistance.
· High tensile strength and tear resistance.
- Good elongation and recovery.
- Very good puncture resistance
- Rot proof.
- Highly resistant to substrate movement.

STANDARDS
PREMIERFLEX 4000 complies with the requirements and tolerance levels of :
1.The American Societty For Testing & Material ASTM D-6164 Type II.
2.UEAtc (European Union of Technical Agreement).
3.MOAT 27-1983 and MOAT 30-1984.
4.CGSB (Canadian General Standards Board) 37-GP56M-July 1980.

INSTALLATION TOOLS REQUIRED
Gas torch, Knife, Trowel, Measuring tape, Marking string, Gloves.

APPLICATION
PREMIERFLEX 4000 is installed by torch welding method, loose-laid or fully bonded to substrate. When loose-laid, only laps are bonded together. Peripheries and protrusions are sealed according to specifications.

COVERAGE RATE
For flat areas

1.13 M2/M2 per layer

For 30 cm. girth flashing

0.35 M2/Mt/ length

Average wastage

3 - 5%

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.
