Section 2How Spray Foam Insulation WorksICYNENE AND ITS PRODUCTSARE REGISTERED TRADEMAR KSOF ICYNENEINC.

Spray Foam BasicsICYNENE AND ITS PRODUCTSARE REGISTERED TRADEMAR KSOF ICYNENEINC. Spray foam insulation becomes a final product onthe jobsite Truck-based spray rigs used to install highpressure spray foam Chemicals delivered in two separate 55-gallondrums (set) Chemical reaction between ISO and resin drums atspray gun results in foam creation

Blowing AgentsICYNENE AND ITS PRODUCTSARE REGISTERED TRADEMAR KSOF ICYNENEINC. Used to expand cells within foam Blowing agent for open cell foam iswater

Blowing AgentsICYNENE AND ITS PRODUCTSARE REGISTERED TRADEMAR KSOF ICYNENEINC. Some blowing agents for closed-cell foamhave high global warming potential (GWP) Lower GWP blowing agents are availableand are being adopted

Low-Density orOpen-Cell SprayFoamICYNENE AND ITS PRODUCTSARE REGISTERED TRADEMAR KSOF ICYNENEINC. Soft, flexible foam (density: 0.4to 0.75 pounds per cubic foot) R-value: R-3.7 to R-4.5 perinch Recognized as air barrier Interior applications only

Low-DensitySpray FoamApplicationsICYNENE AND ITS PRODUCTSARE REGISTERED TRADEMAR KSOF ICYNENEINC. Interior applications only Ceilings, wall cavities,unvented attics, floors, roof,and basement wall interiors Conforms to shape ofsubstrate

Medium-Densityor Closed-CellSpray FoamICYNENE AND ITS PRODUCTSARE REGISTERED TRADEMAR KSOF ICYNENEINC. Harder, rigid foam (density:2.0 to 2.4 pounds per cubicfoot) R-value: up to R-7.1 per inch Water-resistant barrier andair barrier Class II vapor retardertypically at 1.5 inch thickness Interior, exterior, and belowgrade applications

Medium-DensitySpray FoamApplicationsICYNENE AND ITS PRODUCTSARE REGISTERED TRADEMAR KSOF ICYNENEINC. Cavity insulation Continuous insulation Below grade and on buildingexteriors Better solution than rigid foamboard when installed oncurved surfaces

Dual ApplicationsWithin anAssemblyICYNENE AND ITS PRODUCTSARE REGISTERED TRADEMAR KSOF ICYNENEINC. Wall assemblies with bothopen-cell and closed-cellinsulation Achieve high R-values and airsealing with no thermal bridges Strategy limits moistureingress from exterior andinterior

Cost SavingsICYNENE AND ITS PRODUCTSARE REGISTERED TRADEMAR KSOF ICYNENEINC. Multiple functions in a singleapplication save materialand labor Open cell: thermal insulationand air sealing Closed cell: thermalinsulation, air sealing, waterresistant barrier, and vaporretarder

InstallationConditionsICYNENE AND ITS PRODUCTSARE REGISTERED TRADEMAR KSOF ICYNENEINC. Substrate must be dry andabove minimum specifiedtemperature Most common constructionmaterials suitable as substrate Spray foam components mustbe kept within specifiedtemperature range Closed-cell spray foaminstalled in accordance withpass thickness guidance

Section 3Spray Foam ApplicationsICYNENE AND ITS PRODUCTSARE REGISTERED TRADEMAR KSOF ICYNENEINC.

ContinuousInsulationICYNENE AND ITS PRODUCTSARE REGISTERED TRADEMAR KSOF ICYNENEINC. Commonly applies to exteriorof buildings but can occur onbuilding interior too Combines four functions in oneproduct (medium-density cellfoam) Adheres to curves and otherirregular shapes Adheres to most materialswithout a primer

ContinuousInsulation ICYNENE AND ITS PRODUCTSARE REGISTERED TRADEMAR KSOF ICYNENEINC.From a design standpoint,medium-density spray foamexpands the possibilities, as itcan adhere to curved,irregular, and unique shapesand conditions withoutcompromising its performance.In addition, medium-densityspray foam can adhere to mostcommon constructionmaterials without the use of aprimer.

ContinuousInsulation andThermal BridgingICYNENE AND ITS PRODUCTSARE REGISTERED TRADEMAR KSOF ICYNENEINC. Increases thermalperformance by eliminatingthermal bridging Spray foam creates uniformlayer with no joints/seams totreat Fully insulates around brickties and other attachments andpenetrations

Continuous Insulation and Thermal BridgingWhen applied as continuous exterior insulation, spray foam creates auniform layer with no joints or seams to compromise thermalperformance. Spray foam also completely insulates and seals aroundbrick ties and other attachments and penetrations to their full depth,ensuring full thermal performance and airtightness. In comparison, rigidfoam installations often require mechanical fasteners, which cancompromise the continuity and integrity of the insulation.Fitting rigid foam boards around penetrations must be donecarefully to ensure full performance.ICYNENE AND ITS PRODUCTSARE REGISTERED TRADEMAR KSOF ICYNENEINC.

Compatibilitywith OtherMaterialsICYNENE AND ITS PRODUCTSARE REGISTERED TRADEMAR KSOF ICYNENEINC. Cladding materials Transition membranes

Exterior ContinuousInsulation: Air-BarrierPerformanceICYNENE AND ITS PRODUCTSARE REGISTERED TRADEMAR KSOF ICYNENEINC. Medium-density spray foamtypically acts as an air barrierat 1 to 1.5 inches Few rigid foam board productstested Rigid foam board requiresealants, tape, or a membraneto be applied to cover jointsand gaps

Exterior ContinuousInsulation: WaterResistance Medium-density spray foam can serve as awater-resistive barrier (WRB) Rigid foam as WRB ICYNENE AND ITS PRODUCTSARE REGISTERED TRADEMAR KSOF ICYNENEINC.–Joints must be taped or sealed–Some rigid foams not rated as WRBIf insulation too vapor impermeable, wallmay not be able to dry to outside

Exterior ContinuousInsulation: WaterResistanceICYNENE AND ITS PRODUCTSARE REGISTERED TRADEMAR KSOF ICYNENEINC. Prevention of exterior watervapor into a wall is important,but if the wall is too vapor tightat its exterior, it may havetrouble drying to the outsideshould it become wet. Compared to other continuousinsulations, medium-densityspray foam typically provides awall with equal or greater dryingpotential to the outdoors, whichshould enhance durability andlongevity.
