Phenolic Foam Roof Insulation

Above that temperature oxidation is likely to occur and render the phenolic foam insulating boards brittle.

Phenolic foam roof insulation.

In a short amount of time this sulphonic acid corrodes both standard painted deck as well as galvanized deck. Phenolic foam is one of numerous available varieties of insulation. Like our polyiso foam trymer supercel phenolic is manufactured large bunstocks and fabricated into the unique shapes and sizes needed for a variety of commercial applications. Phenolic insulation exposed to humidity or direct moisture such as roof leaking creates sulphonic acid.

Phenolic foam rigid insulation was introduced in the u s. The phenolic foam has been recognized the best insulation material for the excellent fire resistance performance low smoke emission high temperature resistance stability superior thermal performance extremely sound insulating property structural strength performance. Phenolic foam roof insulation consisted of a phenolic foam core bonded to nonasphaltic fiberglass and other facers. Our retrofit specifications for the remediation of projects with phenolic foam insulation set the standard in the industry for this type of specialized project.

Phenolic foam insulation used to be available in board form but today is only sold as a type of foamed in place insulation. It offers many advantages including excellent density and an r value of 4 8 per inch of thickness which forms an effective barrier against heat transfer and thus helps you save energy around the house. In the 1980s and sold by beazer east and johns manville but serious corrosion problems resulted in legal action and both companies ceased production in 1992. Trymer supercel phenolic meets the 25 50 flame smoke requirement established by astm e84 and offers compressive strength that ranges from 32 psi to 158 psi.

As regulations required higher r value insulation in roofs a demand arose for material which offered both fire resistance and high r value while not requiring a full roofing re build to accommodate its thickness. Typically phenolic foams can tolerate continuous temperatures in the 300 degf to 350 degf range with intermittent use up to 400 degf. Interior protection roof removal deck repair and remediation new roof system installations and sheet metal. It was produced in board form in various sizes and thicknesses ranging from 1 inch to 3 3 5 inches 25 4 mm to 91 4 mm.
