Strongduct™ is a unique patented product that offers all the benefits of a pre-insulated system with the strength and durability of a traditional galvanised system. Strongduct™ is the creation of Ken Dalgarno, with over 30 years of experience in the insulation and ducting industry Ken has developed Strongduct to realise his vision of combining two typical products of his livelyhood and produce something that addressed the various downfalls of materials that had changed little over the tenure of his career from apprentice to director. Ken has endeavoured to make a fundamental impact on the HVAC and insulation industries with a truly revolutionary product, Strongduct™. “The idea initially came about as I had noticed a substantial increase in the amount of repair work we were tendering for external lagging jobs, we found that either PIB (polyisobutene) was falling away from the lagging due to it’s age or poor application and in some cases it had be chewed or pecked by vermin. Over the years my company has fitted expensive alternative solutions such as aluminium sheet cladding or an aluminium and polyester laminate, but both were susceptible to human and vermin damage and in many cases it was difficult to achieve a 100% weather-proof seal with limited clearance around various ducts.” - Ken Dalgarno The beauty and simplicity of Strongduct is that we are able to insulate and seal every component of the system and the system is 100% sealed & protected inside and out.
