Wrapsulate® Foam Jacket 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: Wrapsulate® Foam Jacket light density, semi-flexible, spray-applied polyurethane foam, with a primarily open cell structure installed on the exterior of the building;
- Accessories for continuity:
- Blueskin 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;
- 925 BES flexible polymeric moisture-cured sealant, manufactured by Henry® Company; and
- Component for wind load resistance: substrate such as concrete masonry block units (CMU) and exterior gypsum sheathing within a wall designed to withstand the anticipated loads.
If installed as part of the designated air barrier system, Wrapsulate® Foam Jacket light density, semi-flexible spray-applied polyurethane foam, with a primarily open cell structure, serves a dual function in the wall assembly:
- as the principal plane of airtightness of the designated air barrier system
- as exterior insulation; and
- as an exterior sheathing membrane.
The use of the product as insulation is covered under CCMC 14049-R and 14067-R.
The product consists of Wrapsulate® Foam Jacket Part A isocyanate and Wrapsulate® Foam Jacket 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 17 kg/m3 (1.06 lb./ft.3). At a thickness of 25.4 mm (1 in.), the thermal resistance is RSI 0.75 (m2 ·°C/W) R-4.3 (ft.2 ∙°F∙hr/BTU∙in.).

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, with a minimum 38 mm–50 mm thickness (1.5 in.–2 in.) of Wrapsulate® Foam Jacket spray urethane at a 17 kg/m3 density, has demonstrated sufficiently low air permeance with an air leakage rating of A1 (less than 0.05 L/s∙m2∙Pa at 75 Pa reference ΔP) when tested in accordance with CAN/ULC-S742-11, “Air Barrier Assemblies – Specification.” This air leakage conforms to the permissible air leakage rate in the table "Results of testing the air leakage rate of the product" of this Report for as the outermost layer of the exterior wall assembly. The WVP of this product at a 50 mm thickness is approximately 745 ng/(Pa·s·m2).
- The product has demonstrated sufficient strength to resist wind loads so it can be used in low-rise buildings in geographical locations where:
- the wind pressure Q50 at ± 650 Pa (1-in-50-year wind pressure return period found in Appendix C of the NBC 2015), for a maximum building height of 12 m above grade (i.e., 4–5 storeys);
- the CAN/ULC S742 reporting classification is Class A1 for the assembly having been tested to Q50 at ± 650 Pa for a 12 m high building and obtaining an air leakage rate less than 0.05 L/s∙m2∙Pa (see criteria in table "Results of testing the air leakage rate of the product"); and
- The maximum deflection recorded for the metal stud wall was 17.3 mm and for the CMU it was 10.3 mm for a gust wind load of ±1 440 Pa.
- To provide the air leakage control and strength in the field, the product must be installed conforming to the limits above and installed in the field by Urethane Foam Contractors (UFC)-certified installers/contractors according to the Wrapsulate® Air Barrier Insulation Specification, dated June 1, 2015, which contains detailed construction drawings that must be followed. UFC must conduct the necessary follow-up inspections to ensure that UFC-certified contractors are performing the necessary field quality control (for example, transition membrane application, membrane adhesion/pull testing before spraying, sealant application before spraying, spray foam as per CAN/ULC S705.2-05, “Thermal Insulation – Spray Applied Rigid Polyurethane Foam, Medium Density – Application”). All results must be recorded on the UFC daily worksheet for the Wrapsulate® Foam Jacket Air Barrier System.
- A copy of the installation instructions must be available on the job site at all times during the installation for review by building officials. All installers must present their UFC identification card upon request by the building official.
- The product must be identified with the manufacturer’s name or logo and the phrase “CCMC 14096-R.”
This evaluation is based on demonstrated conformance with the following criteria:
|Criteria number||Criteria name|
|CCMC-TG-072709.01-15B||CCMC Technical Guide for Air Barrier Systems for Exterior Walls of Buildings|
The Report Holder has submitted technical documentation for the CCMC’s evaluation. Testing was conducted at laboratories recognized by the CCMC. The corresponding technical evidence for this product is summarized below.
Testing of the product was conducted on four representative specimens. The results are summarized in the tables below. The performance resulting from these tests has been deemed applicable to Wrapsulate® Foam Jacket Air Barrier System based on equivalency testing.
The performance of the product has been tested in accordance with the CCMC Technical Guide for qualification for use as an air barrier system.
To qualify, a conforming air barrier system must:
- have an acceptable low air leakage rate;
- be continuous;
- be durable;
- have sufficient strength to resist the anticipated air pressure load; and
- be buildable in the field.

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 Wrapsulate® Foam Jacket 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 Wrapsulate® Foam Jacket Air Barrier System.
Exterior concrete wall with penetrations
Exterior stud wall with foundations
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.
