The Thermal Insulation Contractors Affiliation (TICA) is asking for a ban on polyisocyanurate (PIR) primarily based insulations being utilized in inner functions.
PIR, a inflexible foam insulation, is usually used on exterior ductwork as a price efficient end when used with exterior weatherproofing/cladding merchandise.
However, TICA is warning, PIR can also be flamable and may pose a hazard when used internally.
TICA suspects that some contractors are utilizing PIR insulation inside buildings to scale back prices as a result of safer options, akin to phenolic duct insulation, are costlier.
The affiliation says that the inner use of PIR needs to be stopped and purchasers ought to take verify the credentials of insulation supplies being put in inside their buildings.
TICA technical coverage supervisor Chris Ridge stated: “Are contractors who proceed to make use of PIR boards on inner duct methods wilfully turning a blind eye or are they blind to the details regarding the merchandise they’re putting in?
“Both means, using PIR board on inner ductwork methods wants to finish. The present financial local weather, the place spiralling prices are impacting many companies, isn’t any excuse for prioritising using cheaper, doubtlessly harmful supplies on the expense of individuals’s security.”
He added: “TICA continues to champion greatest observe within the thermal insulation business. With the publication of the Assemble Product White Paper imminent, it’s time for the development business to take accountability for merchandise which can be getting used within the constructed setting.
“The accountability for making certain compliance can not start and finish with the specialist contractor and people awarding such contracts have to play their half. Within the case of thermal insulation, mechanical and electrical contractors needs to be checking the credentials of the insulation product utilized and asking extra questions of their insulation contractors.”
A spokesperson for insulation producer Kingspan stated: “Therma Duct, our PIR board product for ductwork functions, is examined and CE marked for particular use with externally situated ductwork functions solely and we might not advocate using Therma Duct inside a constructing. We might as a substitute advise our prospects to make use of insulation merchandise which can be CE or UKCA marked, the place relevant, to be used in inner ductwork functions, akin to our Kooltherm Duct Insulation.”
