2 Trisotech Insulation consists of a rigid,closed cell Polyisocyanurate foam core laminated onboth sides to a black, fiber reinforced, non-asphaltic Insulation is offered as 20 psi compressivestrength as a standard, and a 25 psi compressive strengthversion is available upon request. Trisotech Insulation isCFC and HCFC free and the facers are manufacturedfrom 100% recycled material (combination pre-con-sumer and post-consumer)Basic Uses: Trisotech Insulation is used to providehigh thermal Insulation under most roof membranesystems.

3 Trisotech is recommended for use in combi-nation with a coverboard in hot and cold applied BURand MB roof systems. Trisotech Insulation is also avail-able in tapered configurations. Trisotech Insulationmeets ASTM C 1289-11, Type II, Class I, Grade 2 (20psi) and Grade 3 (25 psi).Limitations: Not intended for use under ponding drainage is required. Not to be exposed to solvents, oils or other contam-inants harmful to Polyisocyanurate foam Insulation . Insulation stops are required on roofs with slopes of2:12 (2" per foot) or greater.

4 Not for use directly under hot applied roof mem-branes. A wood fiber overlay Board is required priorto the application of a hot applied roof membrane. Not for use in direct contact with lightweight insu-lating concrete or recently poured gypsum decks. For adhered systems where a cover Board is notspecified, multiple layers of Trisotech must be usedwhen the total Insulation thickness is or greater. For adhered single ply systems when a cover boardis not specified, the maximum thickness for the toplayer of Trisotech is.

5 Sizes: Trisotech Insulation is available in truckloadquantities in 4' x 4' (1220mm x 1220mm) or 4' x 8'(1220mm x 2440mm) Board panels and packaged ondunnage. Thicknesses range from 1" (25mm) to 4"(101mm). Contact your Tremco Representative for afull list of available Trisotech Insulation is specified for applicationin FAS-n-FREE Adhesive or hot bitumen, the recom-mended Board size is 4' x 4'. Board sizes of 4' x 8' areonly acceptable when mechanical attachment of insu-lation is APPLICATION DATA: roof replacement usually involves more complexitiesthan new construction Roofing .

6 Often encounteredare situations such as rusted/deteriorated decks, rot-ted wood components, rooftop equipment whichcannot be moved or shut down, and numerous following application information is designed toserve as a general guide. Your local TremcoRepresentative will prepare detailed specificationsbased on the condition of your Decks:Must be properly designed andstructurally : Ponding conditions are unacceptable andwill adversely affect the performance of any roofingsystem.

7 If positive drainage does not exist, waterremoval from the roof surface must be facilitated bylowering drains, and/or installing additional drains,tapered Insulation , or Tremco approved cellular con-crete Storage: Insulation must be dry and keptdry. When stored outdoors, stack Insulation on palletsat least 4 inches (100mm) above ground level. Uponreceipt of Insulation on the job site, remove the facto-ry plastic packaging. Cover the top and sides of theinsulation with waterproof tarpaulin (not polyethylene)and secure.

8 Do not stack more than two pallets Preparation: Prior to installing the Insulation ,the substrate must be clean, dry and free of dust, dirt,oil, or other contaminants. Concrete and gypsumdecks must be properly cured and sufficiently dryprior to installing Performance CharacteristicsTrisotech InsulationPropertyTypical ValueTest MethodCompressive Strength, Grade 2 - 20 psi (137kPA) ASTM D 3 - 25 psi (172 kPA)Density, nominal lb/ft3( ) ASTM D 1622 Conditioned ThermalResistance at 75 F (24 C)R ValueASTM C 518 LTTR* WEIGHT RECYCLED (lbs/sq ft) CONTENT**1" ( ) " ( ) " ( ) " ( ) " ( ) " ( )

After securing the first layer of Insulation , installthe additional layer(s) with the Board joints offset aminimum 6 inches (150mm) from the joints of thepreceding layer.

10 Two layers, with Board joints offset,can minimize stress on the roof membrane whichresults from thermal movement of the deck. Adhesive Application: Tremco Fas-n-Free, TremcoLow Rise Foam Adhesive, and Tremco Low Rise FoamAdhesive Green are recommended for use withTrisotech Insulation . Obtain and read the SpecificationData Sheets for adhesive products prior to Application: Hot applied asphalt can be usedto adhere Trisotech to concrete decks, to base sheetswhich are mechanically attached to wood or gypsumdecks, and to Insulation layer(s) previously secured.
