Product nameInsulthane® Extreme Air Barrier System
This Evaluation Report addresses the performance of the product as an air barrier system as specified by Elastochem Specialty Chemicals. The product consists of the following components and accessories:
- principal material in the plane of airtightness: Insulthane® Extreme medium density, spray-applied polyurethane foam;
- accessories for continuity:
- Blue Skin SA®, a modified bituminous membrane (i.e., peel-and-stick or thermally fused) manufactured by Henry® Company for use as a transition membrane over construction, control and expansion joints, at junctions between different assemblies and at penetrations;
- backer rod, a closed cell foam weather stripping manufactured by Tago® for use as a gap filler around penetrations (gaps are limited to 1 in. in width), adhered and sealed with BES 925 flexible polymeric moisture-cured sealant, manufactured by Henry® Company; and
- specified sealants that conform to CAN/CGSB-37.29-M89, “Rubber-Asphalt Sealing Compound,” for use at membrane-tofoundation junctions and conforming to CAN/CGSB-19.0-M77, “Methods of Testing Putty, Caulking and Sealing Compounds,” for use on the interior side around window and door openings; and
- component for strength: structural substrate, such as concrete block, exterior gypsum sheathing, oriented strandboard (OSB), or plywood sheathing, within a wall designed to withstand the anticipated loads.
If installed as part of the designated air barrier system, Insulthane® Extreme medium density, spray-applied polyurethane foam serves a dual function in the wall assembly: as the principal plane of airtightness of the designated air barrier system and as exterior insulation. The use of the product as insulation is covered under CCMC 13697-L.
The foam insulation consists of two components: a polyisocyanate (A-side) and a polyurethane resin (B-side). The 2 components are mixed on site by an installer approved by Elastochem Specialty Products to install the product. The resulting product is a Type 2 medium density, spray-applied polyurethane foam with an assigned long-term thermal resistance value of 2.1 m2 •°C/W per 50 mm of thickness. If the foam insulation serves as the principal component in the Insulthane® Extreme Air Barrier System, it must be installed at a minimum thickness and density, which are specified in the conditions and limitations section of this Report. As per CCMC 13697-L, the colour of the finished product is burnt sienna.

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.
Air barrier system
The air barrier system has demonstrated sufficiently low air permeance when it has a thickness of 25.4 mm and a minimum field density of 39.1 kg/m3, which meets the intent of Section 5.4., Air Leakage, and Subsection 9.25.3. of Division B of the NBC 2010 for buildings with an indoor relative humidity (RH) of 35% or less. For buildings with a higher RH (e.g., swimming pools and museums), additional assessment is required in accordance with Part 5 of the NBC.
The structural wind loading conducted qualifies the air barrier system for use in low-rise buildings in geographical locations where the Q50 value does not exceed 0.60 kPa (the Q50 value is the hourly wind pressure for a 1-in-50 year return period, which can be found in Appendix C of the NBC 2010).
To control condensation where the air barrier system’s insulation material has low air and vapour permeance and is installed on the cold side of the wall assembly, the interior vapour barrier must comply with Article 126.96.36.199., Vapour Barrier Materials, of Division B of the NBC 2010. The insulation material must be installed at a 25.4-mm or greater thickness to comply with Article 188.8.131.52., Position of Low Permeance Materials, of Division B of the NBC 2010 for the respective geographical location.
To control air leakage, the proposed air barrier system must be a minimum 25.4 mm thick and installed as exterior insulation over exterior sheathing or a masonry back-up wall.
The product must be installed on-site by Elastochem Specialty Chemicals trained installers following the Elastochem Specialty Chemicals specified product installation manual, which contains detailed construction drawings which must be followed (see Appendix A of this Report for examples). In addition, Urethane Foam Consultants (UFC) carries out follow-up inspections of the installations on a periodic basis.
Air barrier system – field quality assurance
When the Insulthane® Extreme medium density, spray-applied polyurethane foam is applied as the designated air barrier system, Elastochem Specialty Chemicals requires that the installer be trained and that UFC conduct audits to ensure:
- that the approved accessories are being used;
- proper installation of the transition membrane by conducting periodic tension testing as part of the Elastochem Specialty Chemicals specified quality control;
- proper continuity details and substrate conformance as part of the quality control procedure for the product;
- proper application of the Insulthane® Extreme spray foam; and
- that daily work records are maintained for the air barrier system installation.
Insulation – field quality assurance
When the proposed medium density, spray-applied polyurethane foam is applied as spray-foam insulation, the material must be manufactured on-site by qualified installers licensed by Elastochem Specialty Chemicals with field inspections carried out by UFC. UFC certifies the Elastochem Specialty Chemicals training program and provides follow-up inspections to ensure installations are in accordance with CAN/ULC-S705.2-98, “Standard for Thermal Insulation – Spray Applied Rigid Polyurethane Foam, Medium Density, Installer’s Responsibilities – Specification.”
The product must be installed in accordance with the manufacturer’s installation manual. A copy of this manual must be available on the job site at all times during the installation. All installers must present their UFC licensing card and specific site worksheet upon request by the building official.
Note: The Elastochem Specialty Chemicals field quality assurance program calls for periodic audits of the installers, usually random inspections with some mandatory inspections of larger projects. Building officials may contact Elastochem Specialty Chemicals at (519) 754-1678 to request an inspection for a specific job site, if they deem it necessary. In cases where the installation is deemed non-conforming by UFC or Elastochem Specialty Chemicals and is not remedied by the installer, UFC will inform the owner/architect/building official and the CCMC of the non-conforming installation.
See CCMC 13697-L for additional limitations on the installation of the Insulthane® Extreme medium density, spray-applied polyurethane foam product.
The polyisocyanate and polyurethane resin components of Insulthane® Extreme must have their containers (i.e., drums) identified by the phrases “CCMC 14030-R” and “CCMC 13697-L,” respectively.
This evaluation is based on demonstrated conformance with the following criteria:
|Criteria number||Criteria name|

Specimens tested for qualifying system details
The following figures outline the original full-scale specimens tested, which represent typical construction details to be reproduced in the field as part of the installation of Elastochem Specialty Chemical’s current proprietary Insulthane® Extreme Air Barrier System. The representative specimens tested also contained defects (e.g., mortar missing, missing primer gap, etc.) to verify the sensitivity of the air barrier system to these possible field defects and allow for tolerances.
Exterior steel stud wall (no penetrations)
Exterior concrete wall (no penetrations)
Exterior steel stud wall with penetrations
All construction, control, expansion joints or penetrations in an exterior wall assembly must be bridged by a transition membrane as part of the Insulthane® Extreme Air Barrier System.
Exterior concrete wall with penetrations
Exterior stud wall with foundation
As the foundation wall is designated as part of the air barrier system in this case, a transition membrane with sealant (see cross-section details) must be sealed to the foundation wall to maintain the continuity of the plane of airtightness. In addition, note that mechanical fasteners for brick veneer and penetrations from electrical wiring, pipes or ducts must be sealed through the use of a transition membrane.
