    No, we’re not talking about a collective Weight Watchers group-loss goal or the number of plastic straws no longer used by quick serve restaurants, but insulation. According to the results of a new survey released by NAIMA, its member companies in the U.S. and Canada used 3.2 billion pounds of recycled materials in the production of residential, commercial, thermal, and acoustical insulation products in 2017.

    We forecast global revenue growth of around 5% on average for rated construction companies. This will be driven by output growth across all industry segments and most continents, supported by robust economic growth prospects and low interest rates. Our revenue growth forecast is towards the upper end of our 0%-6% range for a stable outlook. We forecast a global book-to-bill ratio, our second outlook metric, at 1.2x on average which reflects the current healthy industry conditions and suggests sustained revenue growth during 2019 and beyond.

    In 2015, the International Energy Conservation Code (IECC) made a new change regarding the thermal resistance requirements for duct insulations in unconditioned spaces. Specifically, the code called for ducts in unconditioned spaces in climate zones 5-8 to be insulated with R-12 insulation.1 (Please see the complete code for all details and any exceptions.) In terms of insulation, designers can expect that the higher the R-value, the greater the insulating power of the insulation.

    Johns Manville’s XSPECT® ISOfoam APF board consists of a uniform closed-cell polyisocyanurate foam core bonded on each side with a foil facer. Polyiso provides one of the highest R-values per inch of any rigid insulation (R-6.0 at 1 inch). R means resistant to heat flow. JM XSPECT ISOfoam APF is produced with an EPA-compliant hydrocarbon-based blowing agent that has zero Ozone Depletion Potential (ODP) and virtually no Global Warming Potential (GWP); it also meets both CFC- and HCFC-free specification requirements.

    When it comes to commercial air conditioning, the great workhorses are rooftop units. People are accustomed to seeing rows of air conditioner cabinets along the top of office and retail buildings. Some commercial buildings still use “split” systems that are similar to the ones seen in residential housing, while restaurants and bars often use ductless heat pumps that send conditioned air wall-mounted blowers that are connected to an outdoor condenser. But the rooftop unit, because of its space saving quality and ease of service, continues to be the most popular for business use.

    As we see a cultural shift toward more energy-efficient and sustainable living, building compliance codes like the International Energy Conservation Code (IECC) are being adopted by more and more local jurisdictions. The IECC is a prescriptive code that has established regulations for energy efficient buildings. The code is designed to help promote the use of new materials, technology, and energy efficient designs.

    Corporate office space is undergoing a rapid transformation. Traditionally, these spaces included a ring of private offices around the perimeter of the space, with cubical farms occupying the center. Today, companies are moving to more of an open office plan, which requires different considerations for HVAC system design.

    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 for a business client.
