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
