Due to sustained supply chain volatility of the raw materials used in polymer resins traditionally used in the manufacturer of Thermomass connectors, Leviat has been forced to temporarily change its standard resin from vinyl ester to a premium isophthalic.
We expected no material difference in the performance of the connectors produced using the temporary formula, and thorough testing of the structural and physical properties of those connectors have verified that all pertinent values for these products remain unaffected.
The sudden nature of this component shortage does, however, technically affect several product lines of Thermomass connectors’ adherence to the International Code Council (ICC) Evaluation Reports (ESR-1746 and ESR-2873). Those reports are predicated on the connectors’ physical, structural, environmental, and third-party quality control test data. Therefore, until all areas have been re-evaluated by the ICC for the substitute resin, or until we are able to return to vinyl ester product, those ICC Evaluation Reports are not applicable for connectors manufactured using isophthalic resin.
Again, there is no material difference in the performance of the connectors using the substitute resin, but until they have been evaluated by the ICC, those connectors will be shipped in boxes without ICC-ES markings. Connectors not affected by this resin change, and in-stock connectors manufactured before the change, will be clearly marked by ICC-ES labels.
Of course, our industry-leading warranty, customer support, and onsite service remains intact for all connectors we manufacture and supply as part of every Thermomass insulation system.
