1.2 CONTEXTUAL APPLICATION & PROTECTION
Condensation & Ventilation:
The Siniat Plasterboard range should not be installed until the building envelopeissealedtopreventmoisturedamagetotheboards.
Condensationofwaterontoeitherthefaceorbackoftheplasterboardmustbeavoided.Insufficientprotectionfromcondensationcanresultinjointdistortion,plasterboardsagging,mouldgrowthandfastenerpopping.Manyinter-relatedfactorsmustbetakenintoaccounttocontrolcondensation.Agoodpracticeistomakeuseofwall/ceilinginsulationandvapourbarriers,aswelltoespeciallyemploygoodventilationsolutions.
Plasterboardcanalsobeaffectedbyhighhumidityconditionsafterinstallationandpriortopainting.Rainenteringunsealedbuildings,wateronfloorsorothersourcesofopenwatermaycauseexcessivehumidity.Thishumiditymaybeabsorbedbyunpaintedplasterboardresultinginsaggingceilings,fungiandmouldgrowthinwallsandceilings.Thereforeplasterboardmustnotbeinstalleduntilthebuildingiswaterproofed.
To minimize the effects of condensation:• UseMoistureCheckplasterboardtoincreaseprotectionagainstmoisture• Usemoisturebarriers.Howeveritisimportantthattherighttypeis selectedfortheconstructiontypeandthatitisinstalledcorrectly(referto manufacturersspecifications)• Usefoilbackedinsulationundermetalroofsastheyaresusceptibleto formingcondensation• Installeaves,gableorridgeventsintheroofcavity• Removehumidityfrombathroomsviaanextractionfantotheoutside• Inhothumidclimateswherethebuildingisair-conditionedbelowthedew pointoftheoutsideair,thewallandceilingframingmembersandinternal liningsshouldbefullyprotectedbymoisturebarrierstoseparatethemfrom thehumidexternalair.Themoisturebarriersshouldbethermallyinsulated tomaintainthematatemperatureabovethedewpoint• Useaqualitypaintsystemtoprovideprotectionagainstpaintpeelingand condensationsoakingintoplasterboardandcompounds• Usethermalbreaksbetweensteelmembersandexternalcladding
