CORBOND ® Performance Insulation System®

Assessing Product Equivalency

When assessing a Closed Cell polyurethane foam insulation product for its equivalency to CORBOND Performance Insulation, it is
important to pay particular attention to the following:

Fire rating – CORBOND III insulation is Class I at up to 6 inch thickness (ASTM E-84). Our practice is to make a product with as low flame spread as technology will allow. We believe this is only right in homes and other
occupied buildings.

Catalyst – Catalysts in foam systems prompt and control the speed of the reaction that forms the foam product. Most foam systems use catalysts that have an odor resembling ‘un-washed socks’ or even a ‘fishy’ smell. These odors are offensive for use in any human occupancy, especially people’s homes. They are also an exposure issue for the foam applicator. We choose a safer catalyst group that we know are more appropriate to the product end use, the installer, and our CORBOND Brand.

Blowing Agent – Some polyurethane and other foam insulations use unsafe petroleum based blowing agents that Corbond Corp believes have no place on a job site or in a home. Some others are blown with the green house gas Carbon Dioxide. CORBOND III uses Enovate® blowing agent by Honeywell Corp, which is a safe, nonflammable, and ozone friendly, high R-Value product that is the latest and best technology available on earth.

Density – CORBOND III insulation is 2.0 lb/cu ft. density and is adjusted for job site altitude. Density indicates the amount of plastic in the finished product which controls strength, moisture permeability, R-Value retention and product longevity. A product manufactured to 1.8 lb density below 1000 ft elevation will loose .2 lb or more of density at 5000 ft elevation and be approximately 1.6 lb density in place. This substantially affects the physical properties of the finished product.

Closed Cell – This describes both the nature and quality of the product. Open cell products are of low density and while they do some thermal and air movement control, they have low R-Value and free moisture vapor
penetration. This compromises thermal resistance in the short term and building longevity in the long term. CORBOND III is Closed Cell which means that each cell is a self contained high R-Value insulator that is
extremely resistant to moisture vapor in any direction in any season. It is this Closed Cell quality that makes CORBOND III true Climate Isolation, an absolute requirement in modern buildings.

Pass Thickness – CORBOND III insulation may be applied to 3 inches in a single pass and not lose its specified density and physical property characteristics even in the core of the bun. This is of utmost importance in product longevity, strength, R-Value retention and low moisture vapor permeance. The strength gives the product resistance to thermal shock at application time and in service during times of exterior temperature change, and peak load. Because pass thickness is in the hands of the applicator, and cannot be controlled by a manufacturers
recommendation, we engineered CORBOND III to allow an impressive 3 inch pass thickness and still maintain the product core characteristics. Other closed cell products specify a maximum pass thickness of 2 inches or less. These restrictions are often ignored by applicators to gain an illegitimate dollar advantage in both yield and labor cost.
.
Application Temperatures – CORBOND III insulation may be applied to substrates at temperature as low as 20° F and still maintain its dimensional stability and adhesive quality without losing its specified physical properties. Moisture conditions can affect the cold temperature application threshold. Full and forever adhesion to substrates is essential to all spray foams for full performance and building sustainability.
k Factor/R Value – Corbond insulation reports its initial k & R factor results using ASTM C-518. Test data for aged R value is available upon request. Good long term R-value retention is one measure of product quality.
Dimensional Stability – Poor dimensional stability relates to undue stresses within the foam product under different climatic conditions. These stresses can compromise the materials long term structural integrity, k or R-Value and in severe cases cause product failure due to shrinkage. CORBOND III is specifically engineered to have excellent dimensional stability.

Color – The trademarked Lavender Color of Corbond polyurethane foam provides owners, architects, builders and code officials a clear way of recognizing the distinctive CORBOND III insulation product. It is a symbol of the highest quality product available today and for the last twenty two years. The Lavender color forms from the mix of blue and red raw materials coming together at the mix/spray nozzle. This is a very effective tool for the applicator to immediately visually detect any equipment or mix malfunction that would compromise the quality of finished product being installed on your project.

Corbond Corporation’s Research and Development Dept has created a product of unsurpassed quality in Closed Cell, medium density, spray polyurethane foam insulation technology today. We have found that a compromise in any of the above key areas produces a product that is unable to measure up to the CORBOND Brand quality standard for an
engineered Performance Insulation System®. Unless that standard is met across the board, product equivalency
cannot be satisfied.
