It has been evaluated by the Council of American Building Officials National Evaluation Service. Health problem concerns associated with other building products in recent years such as asbestos, urea formaldehyde and glass fibers, lead Canadian Authorities to dictate the ground rules for acceptance of new building materials. The Icynene product became, to the best of our knowledge, the most extensively tested insulation material on the market today. The testing included the most sensitive emissions tests developed to date, tests that few other building materials have ever been through. A foam that adheres to building materials, like Icynene insulation, must remain flexible in order to maintain its air seal.
Buildings expand and contract with changes of season and temperature.
If the foam is rigid, it will inevitably develop hairline cracks along the studs and ultimately the air seal will be destroyed. As well as simplifying the construction process for the builder, Icynene Insulation eliminates the major causes of building envelope problems, air-borne moisture movement and entrapment. Blower door tests have shown that a steel framed home insulated with Icynene Insulation, and with no polyethylene vapor barrier, measures 1.2 ACH at -50 Pa. depressurization. This is well under the 1.5 ACH50 rating for the most energy efficient home. Compared to other technologies, The Icynene Insulation System is a less expensive method of building an energy efficient home.
