EXTERIOR FOAM FOR ROOFS

Material and system description

SPF-based roof systems are constructed by mixing and spraying a two-component liquid that forms the base of an adhered roof system. SPF can be installed in various thicknesses to provide slope to drain or meet a specified thermal resistance. A protective surfacing is then applied to the foam to provide protection from the elements.

The first component of an SPF-based roof system is rigid, closed cell, spray polyurethane foam insulation. The foam is composed of two components: isocyanate and polyol. Transfer pumps are used to get the components to a proportioning unit that properly meters the two at a one to one ratio and heats and pumps them through dual hoses. The components are mixed at the spray gun, which is used to apply them to a substrate.

The second component, the protective surfacing, typically is a spray applied elastomeric coating, though hand and power rollers can be used. The protective surfacing also can be a membrane, such as a fleece backed thermoset single ply membrane. The purpose of the surfacing is to provide weatherproofing, protect the foam from UV exposure, provide protection from mechanical damage and assist with the fire-resistant characteristic of the roof system.

Mineral granules or sand may be broadcast into a coating to provide increased surface durability and aesthetic value.

The chemicals used to produce polyurethane foam compounds are manufactured or blended to perform in various temperature ranges. Manufacturers of spray polyurethane foam based roof systems offer materials in different reaction profiles. Profile change is created by altering the chemical ingredients, usually with a catalyst, to compensate for ambient temperature changes. Conditions such as wind speed, sunlight, surface moisture, humidity and temperature of the substrate can affect the reaction of the polyurethane foam.

INTERIOR FOAM FOR ATTICS AND WALLS

Material and system description

Insulation materials are manufactured to meet a variety of specifications and standards. Selecting the best-suited insulation for residential, commercial and other construction projects is dependant on building performance objectives. Performance areas can include safety, durability, air quality, low-cost energy, sustainability and comfort.

Bayseal® insulation not only provides a high R-value but the ability to reduce air intrusion, accumulation, radiative heat transfer and air movement. The application technology allows the spray polyurethane foam to expand, filling cracks, crevices and voids. This creates a “seamless” air barrier system that provides exceptional building envelope performance.

Bayseal® is the “perfect fit” to improve the overall building performance package and create an energy efficient, climate controlled indoor environment.

Bayseal® CCX is a closed-cell foam that seals the building envelope to help create an optimal energy efficient environment. Bayseal® insulation is recommended for non-vented attics, ceilings, floors, foundations, piping, and non-vented crawl spaces. Bayseal® offers an aged R-value of 6.9 per inch. Bayseal® CCXP is designed for cold weather applications to extend the insulation season in cooler climates.

Bayseal® OC open-cell polyurethane foam technology offers a complete air barrier system. Buildings insulated with Bayseal® OC can provide occupants a quieter and more comfortable indoor space. Bayseal® OC can add significant energy efficiency value by filling open voids, cracks and crevices during installation. Bayseal® OC insulation is recommended for walls, attics, ceilings and floors. Bayseal® OC offers an aged R-value of 3.9 per inch.
