    In most applications, the primary feature of a thermal insulation material is its ability to reduce heat exchange between a surface and the environment, or between one surface and another surface. This is known as having a low value for thermal conductivity. Generally, the lower a material’s thermal conductivity, the greater its ability to insulate for a given material thickness and set of conditions.If it is really that simple, then why are there so many different terms, such as K-value, U-more...

    While both residential and commercial HVAC systems serve the same purpose of heating, ventilating and cooling, they vary drastically in terms of mechanism and parts. This is because addressing the need for comfort in a home varies drastically when compared to a work space. Following are 7 major differences between residential and commercial HVAC units…more...

    The average commercial building attributes 40% of its energy costs to heating, cooling, and ventilation, according to estimates from the US Department of Energy. For the typical office building, that equates to 7.5% of its annual operating expenses, on average.Finding efficiencies in your facility’s HVAC system can result in significant savings on operating costs. But it can also yield even bigger returns in non-energy benefits. Improvements in comfort, indoor air quality, and equipmentmore...

    It may be tempting to assume that utilizing a hydrophobic blanket insulation, like InsulThin® HT or silica aerogel blankets, will be sufficient to address CUI, but it’s important to remember that hydrophobicity is not a panacea solution for CUI. While hydrophobic treatments do help prevent water from penetrating into the system, most hydrophobic treatments are silicone-based additives that are organic in nature. As such, these types of silicone-based hydrophobic treatments begin to burn offmore...

    Insulation Outlook
    Microporous insulation is a composite material in the form of compacted powder or fibers with an average interconnecting pore size comparable to or below the mean free path of air molecules at standard atmospheric pressure. Microporous insulation may contain opacifiers to reduce the amount of radiant heat transmitted.more...

    Laser scanning (profilometry) is a highly effective and accurate inspection method for measuring changes in geometry of pressurized vessels, piping and pipelines. The laser scanning data is used to measure the deviations from normal geometry, such as those caused by corrosion, mechanical damage and other structural distortions. The primary goal of the laser scanning analysis is to feed highly accurate geometric data of in-service vessels and components into advanced modelling and analysismore...

    Superhydrophobic surfaces have evoked great interest in researchers for both purely academic pursuits and industrial applications. Metal corrosion is a serious problem, both economically and operationally, for engineering systems such as aircraft, automobiles, pipelines, and naval vessels.more...

    As the industrial industry evolves, new insulation technology has emerged to meet the changing needs of the industry. One of the latest introductions has been thin, blanket insulation. Thin blankets typically range between 5mm and 10mm thick, and can be used in high-temperature or cryogenic applications. Two popular thin blanket insulations are Johns Manville’s InsulThin™ HT, a hydrophobic, microporous, thin blanket insulation, and silica aerogel, a hydrophobic, aerogel, thin blanket insulation.more...

    Sixty-two billion dollars: That’s how much U.S. companies pay each year to cover expenses associated with workplace injuries, according to the Liberty Mutual Workplace Safety Index.It’s no secret a strong workplace safety program is critical for protecting a business’s bottom line and its image as a safe-minded, healthy place to work. Occupational safety and health programs reduce expenses related to medical care, paid time off, litigation and disaster mitigation.more...

    Corrosion can have devastating effects on the integrity of structures and components. Corrosion, if not accounted for, can leave even the best designs useless by compromising the mechanical and chemical properties of many different materials. With proper consideration, however, corrosion can be limited and even prevented almost entirely. There are many different ways that the risk of corrosion can be reduced. This article highlights several of these key areas.Read more about crucialmore...
