It is black in colorand supplied as flat sheets (36” x 48”) instandard thicknesses of 1/8” thru 1-1/2”.It is supplied skin one side with a speciallyformulated scrim reinforced adhesive andtear- and moisture-resistant release lineron the opposite side. INSUL-SHEET ® withPSA is also available in rolls, with a standardroll width of 48”. INSUL-SHEET ® withPSA key physical properties are approvedthrough supervision by Factory MutualResearch Corporation.INSUL-SHEET ® with PSA is non-porous,fiber-free and resists mold growth. AnEPA-registered antimicrobial agent isincorporated into the product providingadditional protection against mold, fungaland bacterial growth.INSUL-SHEET ® with PSA is GREENGUARD ®certified as a low VOC material, meeting therequirements of the “Children and Schools”and “Indoor Air Quality” classifications.APPLICATIONSINSUL-SHEET ® with PSA is used to retardheat gain and prevent condensation orfrost formation on cold equipment, tanks,vessels or ducts. It also effectively retardsheat loss when used on hot or cold equipmentor ducts. INSUL-SHEET ® with PSAis recommended for applications rangingfrom -70°F to 200°F (-57°C to 93°C).INSUL-SHEET ® with PSA speeds up installationtime and reduces the amount ofsolvent-based contact adhesives required,making it ideal for retrofit and OEM applications.The scrim reinforcement reducesthe tendency to stretch the sheet insulationduring installation and improves the peelstrength of the material.INSUL-SHEET ® with PSA thickness hasbeen calculated to control condensation oncold surfaces. Refer to the table on the nextpage for specific recommendations.INSTALLATIONINSUL-SHEET ® with PSA is applied to clean,dry ductwork and equipment by simplypeeling the easy release liner away andapplying uniform pressure to the sheet.Compression joints with adhesive appliedshould be used on all butt edges. See technicalbulletin for installation instructionsin cold temperatures.INSUL-SHEET ® with PSA is also availablewith factory-applied cladding for indoorand outdoor applications. Contact K-FLEXUSA for specific installation instructions.INSUL-SHEET ® with PSA is acceptable foruse in duct covering applications. K-FLEXDuct ® Liner Gray should be used for ductlining applications.OUTDOOR APPLICATIONSFor optimum performance, outdoor applicationsrequire K-FLEX ® 374 ProtectiveCoating, approved jacketing, or K-FLEXClad ® AL or WT. For more detailed information,refer to the Installation Guidelines.RESISTANCE TO MOISTUREVAPOR FLOWThe closed cell structure and uniqueformulation of INSUL-SHEET ® with PSA effectivelyretards the flow of moisture vapor,and is considered a low transmittancevapor retarder. For most indoor applications,INSUL-SHEET ® with PSA needs noadditional protection. Additional vaporbarrier protection may be necessary forINSUL-SHEET ® with PSA when installed onlow temperature surfaces that are exposedto continuous high humidity.FLAME AND SMOKE RATINGINSUL-SHEET ® with PSA in thicknesses of1-1/2” (38 mm) and below has a flamespread rating of 25 or less and a smokedevelopment rating of 50 or less as testedby ASTM E 84, “Surface Burning Characteristicsof Building Materials.” INSUL-SHEET ® with PSA is acceptable for use induct/plenum cover applications meetingthe requirements of NFPA 90A/B.Numerical flammability ratings alone may not definethe performance of products under actual fire conditions.They are provided only for use in the selection ofproducts to meet limits specified when compared to aknown standard.PAGE 42
