Product information

Product name

Duka Open Cell SPF

Product description

The product is a Type 1, spray-in-place, low-density, semi-flexible plastic foam insulation that has an open-cell structure. The product consists of

  • Duka Open Cell SPF part A isocyanate, and
  • Duka Open Cell SPF part B resin,

which are mixed on site by a qualified installer using positive displacement equipment in a 1:1 fixed ratio.

The final cured product is yellow and has a density of 6.8 kg/m3. At a thickness of 25.4 mm, the thermal resistance is 0.61 m2·°C/W.

  Conditions and limitations

The CCMC’s compliance opinion is bound by this product being used in accordance with the conditions and limitations set out below.

  • The product must be applied on site by qualified installers trained and approved by Duka Technologies Inc.
  • As specified by the manufacturer, the product must be manufactured on site by qualified installers trained and approved by Duka Technologies Inc. with subsequent field auditing of installers by Urethane Foam Consultants (UFC).Footnote (1) UFC is the third-party certification organization specified by Duka Technologies Inc. to certify the training program and provide follow-up inspections of qualified installers who are licensed to spray semi-flexible, urethane-based foam insulation in accordance with the Duka Technologies Inc. Installer’s Manual.
  • The product can be installed in new or retrofit constructions. In either case, the product must be installed in open cavities in the following locations in a wood-frame construction that meets the requirements of the NBC 2015 (see Figure 1):
    • exterior walls including perimeter joists;
    • cathedral ceilings with a vented air space as required by the NBC 2015;
    • floors separating living spaces from a garage;
    • cantilever overhang floors; or
    • interior below-grade foundation walls.
  • The building envelope where the product is installed must conform to the requirements of the NBC 2015 for vapour barriers, air barriers and damp proofing (interior below-grade walls).
  • For retrofit applications whereby there may be occupants in the unaltered part of the building, the qualified installer must ensure that the spraying area is isolated and negatively pressurized by using an exfiltration rate of 0.3 air changes per hour for at least 1 day. An independent toxicological assessment determined that this ventilation rate must also be in effect for 1 day before occupancy is permitted in the newly insulated suite.
  • The sprayed material should completely cover the surfaces between the studs, joists and other framing members. The surfaces to be covered should be clean, dry and not covered in frost, oil, grease, dust or other contaminants. As required in Article, Installation of Thermal Insulation, of Division B of the NBC 2015, the insulation must be installed so that there is a reasonably uniform insulating value over the entire face of the insulated area.
  • The interior side of the applied semi-flexible polyurethane insulation must be covered with an approved thermal barrier as per Article, Protection of Foamed Plastics, of Division B of the NBC 2015.
  • The 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.
  • The maximum in-service temperature of the insulation must not exceed 70°C.
  • The product must not be used where it may come in contact with water and must not be installed after its expiry date of 6 months from the date of manufacture.
  • The isocyanate and resin components must have their respective containers (i.e., drums) identified with the phrase “CCMC 14138-R.”
  • The installation procedure must follow the manufacturer’s instruction manual. A copy of the manual must be available at the job site at all times during the installation for review by the building official.
