SIMPLE GUIDELINESTO HELP YOU MAKE THE RIGHT CHOICE

THERMALPERFORMANCE

Read the facts about: • Thermal Performance • R-value per Inch and Weight Limits •AirInfiltration • Cathedral Ceiling Ventilation • Fire Resistance • Health and Safety • Environmental Contribution • Effects of Moisture • Acoustical Performance

Builders face numerous choices when deciding on insulation materials and suppliers. Making the right decision can be confusing.

The most popular*choiceforinsulatinginnewconstructioncontinuestobefiberglassinsulation,althoughsomebuilderschoosecelluloseinsulationasanalternative.FiberglassinsulationisproducedinR-valuesfromR-12toR-60, inbattsandblankets,aswellasloosefill.Celluloseinsulation,whichismadeprincipallyofshreddednewspaperswithfire-retardantchemicaladditives,isproducedonlyinloosefillform,andisinstalledineitheradryblow(inatticsandretrofitwallapplications)orawet-spraymethod(whichisprimarilyusedinnewconstructionsidewallapplications).

CLAIM: Cellulose insulation delivers the R-value stated on its package.

R-VALUE PER INCH AND WEIGHT LIMITS

AIRINFILTRATION

CLAIM: Cellulose insulation has a higher “R-value per inch” than fiber glass insulation.

CELLULOSE INSULATION FACTCelluloseinsulationonlyhasahigherR-valueperinchthanfiberglassinsulationwhereitdoesn’tmatter–inatticapplications,whereinstallationdepthisnotusuallyanissue.However,installinganR-valueaboveRSI4.58(R-26)forstandarddensitycellulose insulation (RSI6.55 (R-37) for lowdensitycellulose)exceeds theweight limitationsgivenbycertaindrywallmanufacturersinconstructionswith24inches(600mm)on-centreframingwith1/2-inch(13mm)drywall.

Cellulose insulationsettlesover time. TheCanadianstandard forcellulosefibre insulation forbuildings,CAN/ULCS703requires the manufacturers to include a coverage chart on their packaging showing the minimum applied and settled thickness requiredtomeetthethermalperformancestated.Thestandardalsodefinesminimumdensity,settlingandthermalresistivityrequirementsthatneedtobemettoensurestatedperformanceonceinstalledinthefield.Failuretomeetalloftheserequirementsmaysignificantlyreducethethermalperformanceoftheproductinstalledinthefield.

Variations in product and installation technique may affect the overall R-value of wet-spray cellulose in wall applications. Installersmayadddifferingpercentagesofwaterand/oradhesivetotheshreddednewspaperinsulation,thusalteringthematerial’sinstalleddensityandactualR-value.

CLAIM: Dense-pack and wet-spray cellulose insulation systems make a house more airtight vs. fiber glass insulation.

CELLULOSE INSULATION FACTCellulose manufacturers claim that their “dense-pack” and wet-spray insulations reduce air leakage through framed wall and atticassemblies,comparedtofiberglassinsulation.However,airleakageoccursmainlythroughpenetrationsthroughtheseassemblies and at connection points of the components that make up the building envelope.

According toTheGuide toAtticAir SealingbyBuildingScienceCorporation attics shouldbe sealedprior to installinginsulation.Addinginsulationalone,withoutairsealing,doesnotprovidesignificantimprovementofbuildingairtightness.

TheNational BuildingCodeofCanada requires the installationof aCONTINUOUSAIRBARRIERSYSTEM. It furtherdetails a maximum air leakage rate of materials that qualify to be used as an air barrier or in an air barrier system.

CATHEDRAL CEILING VENTILATION FIRE RESISTANCE

CLAIM: Some cellulose insulation manufacturers and promoters have stated that it is unnecessary to provide venting between the insulation and the roof deck in cathedral ceiling applications.

CELLULOSE INSULATION FACTCellulose insulation is no different than fiber glass insulation when it comes to following building codes and commonconstruction practices regarding ventilation of cathedral ceilings. To meet building code requirements in all areas of the country –andtosimplyfollowgoodconstructiontechniques–theraftercavitybetweentheroofdeckandtheinsulationmustbeventilated. These codes require unrestricted vent area of not less than 1/150 of the insulated ceiling area for cathedral ceilings orwheretheroofslopeislessthan1in6foranytypeofinsulation.Forattics,theunobstructedventareaisrequiredtobenot less than 1/300 of the insulated ceiling area.

Ventsmayberooftype,eavetype,gableendtypeoranycombinationthereof,uniformlydistributedonoppositesidesofthebuilding and with not less than 25% of the required openings located at the top or the bottom of the space. Most shingle warranties require that the area beneath the roof sheathing or deck be properly ventilated.

HEALTH & SAFETYENVIRONMENTAL CONTRIBUTION

CLAIM: Cellulose insulation is safer to install than fiber glass insulation.

CELLULOSE INSULATION FACTNot enough is known about the safety of cellulose. No health testing by cellulose manufacturers or the cellulose industry exists and no hazard testing or risk assessment evaluations have been done on cellulose insulation. While many cellulose insulationmanufacturersclaimthat theirproduct ismade fromnatural, safe, recycledmaterials, typically20percentofcellulose insulation is chemicals by weight. Some ingredients in shredded newspaper insulation are known to adversely affecthealth:paperdustcauseschronicpulmonaryobstructivedisease,andboricacidandboraxfire-retardantshavebeenshown to cause reproductive disorders in laboratory rats.

Some labour organizations have called for testing the health effects of cellulose insulation and have urged manufacturers to act responsibly and test their products. They have argued that simply because a product is untested does not mean it is safe. Those unions have also asked the federal government to test cellulose insulation. The National Institute of Environmental HealthSciences,throughtheNationalToxicologyProgram,hasagreedtoconductsuchtesting.

FIBER GLASS INSULATION FACTFiber glass insulation is safe to use when the simple directions printed on the package are followed. In terms of safety testing,fiberglassinsulationisoneofthemosttestedbuildingmaterialsever.Studiesconductedoverthepast50yearsinvolving40,000workershavenotestablishedacausalrelationshipbetweenexposuretoglassfibersandcanceroranyotherdiseaseinplantworkersorinstallers.Infact,duringthelast50years,morethan600reportsandscientificarticleshavebeenpublishedonthesubject.

ACOUSTICALPERFORMANCE

CLAIM: Cellulose insulation can be installed without a vapour retarder.

CELLULOSE AND FIBER GLASS INSULATION FACTVapour retarders or vapour retarding paint are required in new construction by the National Building Code of Canada. TheBuildingCodestates:“Thermallyinsulatedwall,ceilingandfloorassembliesshallbeconstructedwithavapourbarriersoastoprovideabarriertodiffusionofwatervapourfromtheinteriorintowallspaces,floorspaces,atticorroofspaces.”“Vapourbarriersshallhaveapermeancenotgreaterthan60ng/(Pa.s.m2).”

CLAIM: Dry-blown and wet-spray cellulose insulations are not corrosive to wiring, nails or metal pipes.

CELLULOSE INSULATION FACTSeveral problems are presented by the installation of dry-blown or wet-spray cellulose insulation:

•CelluloseinsulationlosesR-valuewhenwet,andtheratedR-valueofthematerialwillnotbeachieved until it is completely dry. •Ifcelluloseinsulationcollectsmoisture,itmayleadtorottingofframingmembers.Moisturecombined withcertaincombinationsoffire-retardantchemicalsmayalsoleadtocorrosionofwiring,nails,pipes and other metals in the structure.

Standardformulationsoffireretardantchemicalsandcellulosefiberaretestedforfungiresistanceandcorrosivenessatleast once every three years. Cellulose with alternate blends of chemicals or depleted chemicals due to separation of the powders or moisture cycling migration may not be fungi resistant or may be corrosive.
