Description

IMCOSHEET™ 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

IMCOSHEET™ insulation is used to retard heat flow and provide condensation control on large diameter piping, tanks, vessels and equipment.

IMCOSHEET™ 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. Acceptable for use with heat tracing/heat tapes.

Installation

When IMCOSHEET™ insulation is applied to equipment, use 100% coverage of 320 and 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 Applications

IMCOSHEET™ insulation is made from UV resistant polyolefin resins. For severe UV exposure (rooftop applications) or where optimum performance is required, a protective jacketing (PVC) should be used. Coatings do not adhere well to polyolefin insulation. Refer to installation guidelines for specific instructions.

Resistance to Moisture Vapor Flow

The closed-cell structure of IMCOSHEET™ insulation effectively retards the flow of moisture vapor and is considered a low transmittance vapor retarder. For most applications, IMCOSHEET™ insulation needs no additional protection.

Additional vapor barrier protection may be necessary for IMCOSHEET™ Insulation when installed on low temperature surfaces that are exposed to continuous high humidity.

Flame and Smoke Rating

IMCOSHEET™ 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.
