Products > therma-cel Sheet Insulation Descriptiontherma-cel® Sheet Insulation is a flexible, polyolefin, thermal insulation. It is black or white in color and available in sheet and roll form. Standard sheet size is 36" x 48" in thicknesses of 3/8" thru 2 1/2". Standard roll width is 48" available in the same thickness. Applications
therma-cel® Sheet Insulation has a low thermal conductivity and very low water vapor transmission rate. This low density product demonstrates excellent thermal, physical and chemical resistant properties and has a broad service temperature range between -330°F and 210°F (-201°C and 99°C). It can be installed in commercial, industrial and residential insulation projects. InstallationWhen therma-cel® Sheet Insulation is applied to equipment, use 100% coverage of 320 or 620 Contact Adhesive or other approved adhesive system. Since it is a contact adhesive, both surfaces to be joined should be coated and then joined after adhesive is dry to the touch. Compression joints with adhesive applied should be used on all butt edges. Refer to Installation Guidelines for specific instructions. Outdoor Applicationstherma-cel® sheet insulation is made from UV resistant polyolefin resins. For severe UV exposure(rooftop applications) or where optimum performance is required, the product must be protected from the elements. Various jacketing or cladding materials are recommended, ie. PVC, CPVC, AL, etc. If coatings are going to be used, please refer to technical bulletin for recommended coatings. Resistance to Moisture Vapor FlowThe closed-cell structure and unique formulation of therma-cel® Sheet Insulation effectively retards the flow of moisture vapor and is considered a low transmittance vapor retarder. For most indoor applications, therma-cel® Sheet Insulation needs no additional protection. Additional vapor barrier protection may be necessary for therma-cel® Sheet Insulation when installed on low temperature surfaces that are exposed to continuous high humidity. Flame and Smoke Ratingtherma-cel® Sheet Insulation in wall thicknesses of 1" (25 mm) and below has a flame spread rating of 25 or less and a smoke development rating of 50 or less as tested by ASTM E 84 Method of Testing entitled: “Surface Burning Characteristics of Building Materials.” Numerical flammability ratings alone may not define the performance of products under actual fire conditions. They are provided only for use in the selection of products to meet limits specified, when compared to a known standard. Specification Compliance• ASTM C 1427, Type 2, Grade 1 |
