Description
K-FLEX™ LS Sheet with Self Seal Pressure Sensitive Adhesive (PSA) Insulation 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" through 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.
K-FLEX™ LS Sheet with PSA is also available in rolls, with a standard roll width of 48". K-FLEX™ LS Sheet with PSA key physical properties are approved through supervision by Factory Mutual Research Corporation.
K-FLEX™ LS 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 reinvorcement improves peel strength.
Applications
K-FLEX™ LS Sheet with PSA is used to retard heat gain and prevent condensation or frost formation on cold equipment or ducts. It also effectively retards heat loss when used on hot or cold equipment or ducts. K-FLEX™ LS Sheet with PSA is recommended for applications ranging from -70°F to 200°F (-57°C to 93°C). K-FLEX™ LS 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.
K-FLEX™ LS Sheet with PSA can be used as a duct covering.
K-FLEX™ LS Sheet with PSA thickness has been calculated to control condensation on cold surfaces. Refer to the specification sheet for specific recommendations.
Installation
K-FLEX™ LS Sheet with PSA Insulation is applied to clean, dry surfaces 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.
K-FLEX™ LS Sheet with PSA is acceptable for use in plenum applications, meeting the requirements of NFPA 90A/B.
K-FLEX™ LS Sheet with PSA is also available with a pre-applied factory cladding for outdoor and indoor applications. Contact Nomaco K-Flex for specific installation instructions.
Outdoor Applications
For optimum performance, outdoor applications require R-374 Protective Coating or other recommended protective coating, cladding or jacketing. For more detailed information refer to the Application Guide.
Resistance to Moisture Vapor Flow
The closed-cell structure and unique formulation of K-FLEX™ LS Sheet with PSA effectively retards the flow of moisture vapor, and is considered a low transmittance vapor retarder. For most indoor applications, K-FLEX™ LS Sheet with PSA needs no additional protection.
Additional vapor barrier protection may be necessary for K-FLEX™ LS Sheet with PSA when installed on low temperature surfaces that are exposed to continuous high humidity.
