Proline Plus™ 1LB Product Information
Proline Plus™ 1LB is a light-density, open-cell, spray-applied, semi-rigid polyurethane foam insulation for use in residential, commercial, industrial and institutional structures. Sprayed in place as a liquid, a chemical reaction causes expansion to yield high-quality foam insulation.
Proline Plus™ 1LB is formulated with 20% recycled materials and meets or exceeds the standards set out in CAN/ULC S712.1 and the CCMC (Canadian Construction Materials Centre) Open-cell Technical Guide 07 21 19.03. Proline Plus™ 1LB is recognized by NRC (National Research Council of Canada) under CCMC listing #13656-R.
Application of Proline Plus™ 1LB may be performed only by Trained Professionals adhering to the Urethane Foam Consultants (UFC) Field Quality Assurance Program. Proline Plus™ 1LB can be sprayed into walls, ceilings, floors, attics and crawl spaces. Excess insulation can be trimmed within seconds of spraying, allowing drywall and/or finishing surfaces to be installed as soon as the application is complete. Proline Plus™ 1LB can also be used for pour-in-place foam applications.
Proline Plus™ 1LB is intended for use in residential, commercial, industrial and institutional buildings. It seals cavities, reduces heat migration and reduces energy consumption without restricting moisture vapour.
Proline Plus™ 1LB is designed for use within or outside the building envelope, above or below grade, between wood or steel framing members.
- Refer to the Proline Plus™ Installer’s Manual for instructions.
- Store in a well-ventilated area.
- Maintain storage temperature between 18–30º C (65–86º F).
- Do not heat above 60º C (140º F).
- Do not allow to freeze.
Containers & Storage
Proline Plus™ 1LB is supplied in “material sets” consisting of two liquid components contained in 55-US-gallon drums. Component A, isocyanate, is in red drums. Component B, resin, is in white drums.
Components should be stored in a well-ventilated area maintained between 18–30º C (65–86º F). Do not allow components to freeze. Do not heat components above 60º C (140º F).
For best results, Proline Plus™ 1LB should be sprayed at 1200–1400 psi fluid pressure with materials heated to 49–54º C (120–130º F). Component B (white drum) should be well mixed prior to and during application.
Trained Professionals spraying Proline Plus™ 1LB can achieve yields between 21.2–23.6m3 (9–10,000 bd ft) of high-quality foam per material set.
Safe for Electrical Wiring
Proline Plus™ 1LB can be applied over 14/3 and 12/2 wiring without affecting wire coverings.
Safe for Plumbing
Proline Plus™ 1LB is safe for PVC (polyvinyl chloride), ABS (acrylonitrile butadiene styrene), PEX (cross-linked polyethylene), copper and steel piping systems.
Use Caution Near Heat-emitting Sources
Insulation must be kept away from heat-emitting devices, such as recessed light fixtures and chimneys, at the minimum distance required by building regulations and safety codes. Gap should never be less than 75mm (3”).
Does Not Support Bacteria or Fungi
Proline Plus™ 1LB is not a source of nutrients or sustenance for bacteria or fungi. Air sealing provided by Proline Plus™ 1LB prevents infiltration of moisture, nutrients and spores.
Does Not Support Insects, Rodents or Other Pests
Proline Plus™ 1LB is not a source of food for insects, rodents or other pests.
Environmental Health & Safety
Proline Plus™ 1LB is a water-blown product which is free of CFCs (chlorofluorocarbons), HFCs (hydro fluorocarbons) and HCFCs (hydro chlorofluorocarbons).
The Saskatchewan Research Council has tested Proline Plus™ 1LB for VOCs (volatile organic compounds) off gassing and recommended extremely sensitive individuals delay occupancy for one day.
