Insul-Sheet® with PSA

Designed for the HVAC/R Industry

Description

INSUL-SHEET® with Pressure Sensitive Adhesive (PSA) is an environmentally friendly, CFC-free, flexible elastomeric thermal insulation. It is black in color and supplied as flat sheets (36” x 48”) in standard thicknesses of 1/8” thru 1-1/2”. It is supplied skin one side with a specially formulated scrim reinforced acrylic adhesive and tear resistant release liner on the opposite side. INSUL-SHEET® with PSA is also available in rolls, with a standard roll width of 48”. INSUL-SHEET® with PSA is non-porous, non-fibrous and resists mold growth. The Bio-Guard™ antimicrobial system provides added protection against mold, fungal and bacterial growth.  The active ingredient in Bio-Guard™ is registered with the EPA.

Features of PSA: tear and moisture resistant easy release liner, reinforced scrim prevents stretching insulation & scrim reinforced improves peel strength.

Applications

INSUL-SHEET® with PSA is used to retard heat gain and prevent condensation or frost formation on cold equipment, tanks, vessels or ducts. It also effectively retards heat loss when used on hot or cold equipment or ducts. INSUL-SHEET® with PSA is recommended for applications ranging from -70°F to 200°F (-57°C to 93°C). INSUL-SHEET® with PSA speeds up installation time and reduces the amount of solvent based contact adhesives required thus making it ideal for retrofit and OEM applications. The scrim reinforcement reduces the tendency to stretch the sheet insulation during installation as well as improving the peel strength of the material.

INSUL-SHEET® with PSA thickness has been calculated to control condensation on cold surfaces. Refer to the Submittal Sheet for specific recommendations.

Installation

INSUL-SHEET® with PSA Insulation is applied to clean, dry ductwork and equipment by simply peeling the release liner away and applying uniform pressure to the sheet. Compression joints with adhesive applied should be used on all butt edges. See technical bulletin for installation instructions in cold temperatures.

INSUL-SHEET® with PSA is also available with factory-applied cladding for outdoor applications. Contact Nomaco K-Flex for specific installation instructions. INSUL-SHEET® with PSA is acceptable for use in duct covering applications.

Outdoor Applications

For optimum performance, outdoor applications require R-374 Protective Coating or other recommended protective coating, facing or jacketing. For more detailed information refer to the Installation Guides.

Resistance to Moisture Vapor Flow

The closed-cell structure and unique formulation of INSUL-SHEET® with PSA effectively retards the flow of moisture vapor, and is considered a low transmittance vapor retarder. For most indoor applications, INSUL-SHEET® with PSA needs no additional protection.

Additional vapor barrier protection may be necessary for INSUL-SHEET® with PSA when installed on low temperature surfaces that are exposed to continuous high humidity.
