TICA Warns Against Non-Certified PIR Boards on Ductwork  

MEMBERS of the Thermal Insulation Contractors Association (TICA) are warning against the use of Euroclass F, non-certified PIR boards on ductwork.

The trade body originally sounded the alarm over the use of PIR on internally located ductwork in November 2022. However, it is now also highlighting a growing issue over the use of non-certified PIR boards on externally located ductwork.

An increasing number of TICA members have reported that they are losing work due to competitors using a cheaper non-certified alternative – a situation that is being perpetuated due to the fragmented nature of the construction sector, making it more difficult to establish a ‘golden thread’ of safety data.

TICA Warning

Chris Ridge, TICA Technical Director said: “There are several manufacturers of PIR board operating in the UK and TICA is aware of only one PIR product that is certified for specific use with externally located ductwork. We have witnessed the use of many different PIR brands and clearly many of these have not been certified for the required application.

“Everyone in the supply chain must ensure that the correct products are being used. Manufacturers, distributors, and installers all have a responsibility.”

He added: “Manufacturers need to be clear and unambiguous about where their product can and can’t be used. The one manufacturer that has certified their PIR product for use with ductwork is very clear about the fact that its product is only suitable for externally located ductwork.

“The ambiguity that exists elsewhere will only increase the chances of PIR products being used in internally located ductwork applications.

“Clients also need to take responsibility and ensure that they employ only competent specialist sub-contractors to insulate ductwork.”
