PRODUCTS
MATERIALS – GENERAL
.1
Acceptable insulation manufacturers are Owens Corning Canada, Johns Manville, Manson
Insulation Inc., Knauf Fiber Glass and Certainteed.
.2
Provide insulation and covers in strict accordance with authorities governing combustibility
and fireproofing of materials and in accordance with manufacturer's recommendations.
.3
Provide non-combustible insulation, jackets and finishes having a Flame Spread/Smoke
Developed rating of 25/50 or less, meeting CAN/ULC S-102 requirements.
.4
Attain a complete and continuous vapour barrier over insulation applied to cold and dual
temperature piping, sheet metal and equipment. Use either factory applied vapour barrier
jacket or field applied Reinforced Foil Flame Resistant Kraft vapour barrier jacket. Apply to
piping, fittings, valves and inline components, sheet metal and fittings and equipment. Seal
longitudinal and circumferential laps with Childers CP82 or Bakor 230-39 adhesive. If vapour
barrier jacket is not lapped, seal joints with self-adhering {100mm} [4"] wide plain aluminum
foil tape, or adhere {100mm} [4"] wide aluminum foil tape with Childers CP82 or Bakor 23039 adhesive. Jacketing with self-adhesive laps and self-adhesive vapour barrier tape will be
an acceptable alternative closure system.
.5
Recover all exposed insulation and insulation finishes with minimum {0.20kg/squaremetre}
[6oz.] canvas, and two applications of Childers CP50 or Bakor 120-09 white fire resistant
coating. An acceptable alternative recovering will be PVC fitting covers and jacketing,
