Welcome to our new blog! With 40 years of industry experience, we’ll be bringing you insightful and informative blog posts that cover a wide range of topics. We’ll be blogging general tips and information about  low pressure spray polyurethane foam (SPF), educational information on using SPF products, application tips, and best practices for growing or adding an SPF business, as well as regulation and industry news.


Air Barrier Properties and Building Envelope Science 

Posted by Amber Christopher April 23, 2015

Stopping unwanted air infiltration into residential homes and commercial buildings is one of the most important and cost-effective ways to reduce heating and cooling costs, improve indoor air quality, and provide a more durable, energy-efficient construction. State-of-the-art building science is focused on increasing energy-efficient construction through the design of, among other things, superior air barrier systems within the building envelope. The building envelope is the boundary that separates outside air, moisture, wind, etc., from the inside conditioned space. In fact, the importance of the air barrier is such that current and future air barrier testing standards are being incorporated into new residential and commercial building codes. The new codes will significantly impact construction techniques in the coming years.


Handi-Foam® E84 Low Pressure Spray Polyurethane Foam (SPF) 

Posted by Amber Christopher April 23, 2015

Handi-Foam® E84 Class 1 Two-Component Polyurethane Foam is one of a family of fire-rated products available from Fomo Products, Inc. This Technical Bulletin serves to clarify the various issues relating to the use of Class 1 foam in construction practices.


Explanation of Expansion Rate for Low Pressure One-Component and Two-Component Foams 

Posted by Amber Christopher April 23, 2015

The “expansion rate” or percentage of expansion for one-component and two-component polyurethane foams is often quoted for marketing or technical purposes. Currently, there is no single consistent testing method that all manufacturers use to measure expansion, and therefore, it is often misused or misunderstood. This Technical Bulletin will further qualify and explain this properly.


Fireblock and ASTM E814 (UL 1479) 

Posted by Amber Christopher April 23, 2015

Polyurethane foam is an organic plastic polymer. Therefore, it is combustible and will burn in the presence of sufficient heat, ignition, etc. With the addition of flame retardants, PU foams can be formulated to pass flame-spread tests (i.e., ASTM E84), which measure their resistance to combustion when exposed to an open flame. However, polyurethane foam is not intended to be used by itself as a firestop material, according to current accepted U.S. model building codes, such as ICC, NFPA, etc., which specify that through-penetration firestop materials be tested according to ASTM E814 (UL 1479). In order to pass firestop testing as the sole material being tested (no composite structures), a material must essentially be noncombustible, which is not the case for polyurethane foams.


Handi-Foam® Spray Polyurethane Foam (SPF): An Approved Flood Damage-Resistant Material 

Posted by Amber Christopher April 23, 2015

Home renovations continue to be a priority in flood-ravaged areas devastated by recent hurricanes.  As professional contractors, it is more important than ever to specify flood damage-resistant products in your rebuilding projects.


Handi-Foam® E84 Low Pressure Spray Polyurethane Foam Roof-Wall Juncture Class 1 Report Summary 

Posted by Amber Christopher April 23, 2015

Fomo Products, Inc.’s Handi-Foam® E84 Class 1 Low Pressure Spray Polyurethane Foam insulation has been approved for use as an air infiltration barrier in buildings of all types of construction. Handi-Foam E84 SPF was tested in accordance with NFPA 286 in a stimulated end-use configuration, meaning that the product can be left exposed in commercial roof/wall junctures.


Leadership in Energy and Environmental Design (LEED®) 

Posted by Amber Christopher April 23, 2015

The Leadership in Environmental Energy and Design (LEED®) Green Building Rating System is a nationally accepted benchmark for the design, construction and operation of high-performance, green buildings. LEED encourages and accelerates global adoption of sustainable green building and development practices through the creation and implementation of universally understood and accepted tools and performance criteria.


Low Pressure One-Component Polyurethane Foam for Windows and Doors 

Posted by Amber Christopher April 23, 2015

Low pressure one-component polyurethane foam sealants (OCF) have been traditionally used for many years to successfully seal around windows, doors and skylights, in addition to a variety of other areas, such as along base plates, corner joints, around plumbing and utility penetrations, etc. As the use of alternative materials for manufacturing windows has become more common, in particular, vinyl windows, the potential for window failure or defects due to improper installation has also increased. One reason is that the materials used to make the windows have become increasingly lighter and less structurally robust, and therefore, more prone to distortion.


Moisture Vapor Transmission (“Perm” Rating of Handi-Foam® Low Pressure Polyurethane Foam) 

Posted by Amber Christopher April 23, 2015

Water in its low-energy state (liquid) does not permeate through polyurethane closed cell foam, and in its high-energy state (vapor) its permeance is retarded significantly. Because of its very low moisture vapor transmission properties, polyurethane foam may be considered a “vapor retarder” when applied in sufficient thickness. There is not a strict definition of what constitutes a vapor retarder vs. a vapor barrier. Furthermore, the outstanding insulating and air barrier properties of Handi-Foam® Two-Component Polyurethane Foam, when applied to form a seamless, monolithic coating make it an excellent solution to the problem of moisture condensation and humidity buildup in properly designed construction.
