    Companies looking for insulation replacement solutions for commercial buildings should keep in mind that there are many wrong ways to implement these projects. Mistakes made in getting commercial installation in place can destroy energy efficiency initiatives and cost businesses a lot of money. They can lead to non-compliance with industry standards, and raise risks.Here are some of the things that a professional HVAC company takes care to avoid during commercial insulation repair projects formore...

    Corrosion under insulation (CUI) is a concern that industrial owners, engineers, and contractors spend a great deal of time managing every day.  As a leader in the industrial insulation market, Johns Manville conducts corrosion-based testing to provide the industry with the information they need to make decisions.  Johns Manville conducts tests using industry-accepted laboratory-scale ASTM protocols, as well as tests under simulated “real-world” environmental and installationmore...

    Corrosion is a major challenge and essential risk to contain for any oil and gas operator. Loss of containment can mean loss of process, loss of revenue, expensive repairs and – most importantly – a potentially major safety hazard. But while a breach in a cross-country pipeline can be a major incident and environmental risk, it’s another matter downstream. Different plant and processes are tightly packed together, with all manner of hydrocarbons and other combustible fluids boiling, cooling ormore...

    The nuclear, renewable-energy and construction sectors also spend a fortune monitoring corrosion that is hidden under insulation.For the offshore sector, corrosion under insulation (CUI) on pipelines and other infrastructure is estimated to cost about £3.5 billion a year.Current practice relies on periodic removal of insulation in selected areas to check visually for problems – but that could be about to change.more...

    As we discussed in our previous article, corrosion under insulation (CUI) is one of the most difficult corrosion processes to prevent. The reason for that is, by and large, no matter the precautions taken, water invariably seeps into the insulation and begins its dirty work—sometimes unseen until process leakage occurs. Data shows that about 60% of pipe leaks are caused by CUI. That’s not good.more...

    The 2018 edition of the International Energy Conservation Code (IECC) has been published, and it includes new provisions regarding HVAC ducts buried in vented attic insulation. The code changes, proposed by Craig Drumheller from the National Association of Home Builders (NAHB), allow ducts to be buried in attic insulation, and when using the performance path, provides credit for the improved duct efficiency.    We sat down with Craig to dive into some of the details of hismore...

    Johns Manville is proud to announce its release of the first ever flexible fiberglass duct liner with an R-12 thermal resistivity rating. This innovative insulation is designed specifically to meet the new code requirements set forth by the IECC in 2015 that mandate the use of R-12 insulation on ducts in unconditioned spaces in climate zones 5-8.Click here to read more about this new R-12 duct liner. more...

    In 2017 and 2018, Johns Manville built upon the long-term, third-party corrosion testing we started in 2016, and the new results are in. The research sought to explore how corrosion under insulation (CUI) impacts a completely insulated pipe system (pipe, insulation, and jacketing) under conditions designed to accelerate corrosion. The test program started in 2016 with two hydrophobic high-temperature blanket insulations (InsulThin™ HT microporous blanket and a silica aerogel blanket) and inmore...
