Building Envelope Educational Courses, Tools, and Materials
May 29, 2019
The demand for high-performance building envelope systems is on the rise. Energy codes such as ASHRAE 90.1 and the IECC continue to increase requirements aimed at creating more energy efficient and environmentally friendly designs. Some of these increasing code requirements involve the addition of continuous air barriers, as well as continuous insulation to wrap the entire building. Architects, specification writers, and designers have the almost impossible task of staying up-to-date on new code requirements, understanding how and why changes were made, and accurately and appropriately incorporating these changes into their designs.

Over the last several decades, Carlisle Construction Materials (CCM) has become the premier single-source supplier of building envelope materials, including single-ply roofing, air and vapor barriers, waterproofing membranes, insulation, metal products, and more. Therefore, CCM is focused on educating and assisting design professionals through training courses, as well as helpful tools and materials, to minimize the learning curve experienced by architects when code changes occur. Here’s some information on CCM’s newest educational courses, tools, and materials to help you stay at the forefront of building envelope designs.

Education is paramount to the success of building envelope projects, which is why CCM offers free courses to design professionals on various building envelope design considerations. CCM’s “Pushing the Envelope: Going Beyond Conceptual Design” is a 300-level, AIA-accredited course that explores proper product selection, material performance characteristics, test procedures, and best practices as they relate to building envelope systems. It is available online as a self-guided course here or you can request a face-to-face presentation here.

CCM’s newest course, “Building Envelope Design – Understanding Codes, Best Practices, and Tie-in Detailing”, is a 400-level, AIA-accredited course available exclusively as a face-to-face presentation. This course helps raise awareness of code requirements as they relate to building envelope components and systems, with a focus on the all-important tie-in detailing needed to provide an air tight building. Common material misconceptions are also discussed. For more information on CCM’s Building Envelope Design course, or to request an face-to-face presentation, click here

As energy code requirements increase the need for air barriers and continuous insulation, questions about fire safety may arise. In most cases, the International Building Code (IBC) requires compliance with NFPA 285, which is the Standard Test Method for Evaluation of Fire Propagation Characteristics of Exterior Wall Assemblies Containing Combustible Components. Carlisle Coatings and Waterproofing (CCW) offers both an online tool and mobile app that allow you to build an NFPA 285-approved assembly. When finished, a submittal document is created for the wall you designed, and this document can be provided to your building code official if your design is ever called into question. To build your NFPA 285 wall assembly, click here or download the app by searching “NFPA Guide” on the AppStore, GooglePlay, and Amazon.

Since continuous air barriers became a requirement of energy codes, building designers have been given the difficult task of determining material compatibility and proper tie-in sequencing of dissimilar systems. CCM’s breadth of building envelope materials allows for the internal vetting of material compatibility, taking away the guesswork typically required from designers. CCM’s NVELOP details are easy to read and understand, illustrating the most common material combinations along with step-by-step installation instructions to create the continuous air seal required by energy codes. NVELOP details can be downloaded from the NVELOP website here.

CCM is unique in its ability to provide a wide range of materials from a single source. Similarly, NVELOP is unique in its ability to provide a single-source warranty for the tie-ins between dissimilar CCM systems. However, the uniqueness of CCM and NVELOP can make specifying for public bid projects complicated. To address these difficulties, CCM developed the MasterFormat Specification Sell Sheet with instructions on how to write CCM and NVELOP as the basis of design in public bid project specifications, while keeping them open for competition. To download CCM’s NVELOP MasterFormat Specification Sell Sheet, click here.

NVELOP is unique in its ability to provide warranty coverage for tie-ins between dissimilar CCM materials. Traditionally, applying for and receiving a warranty for tie-ins was either impossible or extremely difficult and involved lots of paperwork and time. NVELOP eliminates these issues with an easy online warranty application process. Once the individual CCM system warranties are purchased and received, visit NVELOP’s warranty application portal here and fill in the appropriate information.

Alternative Uses for Roofing Membranes

All single-ply membranes make for great roofing systems, but they can be used for a variety of other purposes too. EPDM, TPO, and PVC can be used in the lining of underground tunnels and can serve as liners for water retention ponds, irrigation canals, and other water containment systems. For years, EPDM membranes were used as pond liners – even before they were utilized for commercial roofing. You could see EPDM pond liners being used in agriculture for irrigation canals and ditches, by municipal water systems for retention ponds and spillways, and even in backyards as small ponds and water features. This is still true today, and EPDM has expanded into additional markets such as tunnel waterproofing. The number of large underground transportation tunnels used for vehicle traffic or metropolitan railways has certainly increased in the last few decades as traffic and access needs continue to outstrip the supply of existing infrastructure. These tunnels have to keep water out, whether they’re underneath a river or traversing through a mountain, and single-ply membranes meet their waterproofing needs with the same technology used on the roof. Different types of membrane offer specific benefits, from EPDM’s large sheet size to thermoplastics’ (TPO/PVC) seam weldability. Regardless of whether the tunnel is a boring project or a “cut and cover”, lining the tunnel can be accomplished using several different installation methods and can utilize EPDM, TPO, or PVC. For more information, please consult the links for the products or specifications on the Carlisle SynTec website below. Tunnels – Conventional Blindside Method Consult the Tunnel Waterproofing System – Conventional Specification and Details on the Carlisle SynTec website.  Tunnels – Cut and Cover Method Consult the Tunnel Waterproofing System – Cut and Cover Specification and Details on the Carlisle SynTec website.  Pond Liners Consult GeoMembrane Page for Pond Liner Products and Brochures on the Carlisle SynTec website.   Contact Craig Tyler at [email protected] with questions.

Understanding FM 1-52

There are two recognized field test methods for determining uplift resistance of adhered membrane roof systems, both of which can be problematic: ASTM E907, "Standard Test Method for Field Testing Uplift Resistance of Adhered Membrane Roofing Systems," and  FM Global Loss Prevention Data Sheet 1-52 (FM 1-52), "Field Verification of Roof Wind Uplift Resistance."  Both test methods provide for affixing a 5’ x 5’ dome-like chamber to the roof’s surface and applying a defined negative (uplift) pressure inside the chamber to the roof system's exterior-side surface using a vacuum pump, like in the photo below.  An example of a test chamber used for negative-pressure uplift testing However, ASTM E907 and FM 1-52 differ notably in their test cycles and maximum test pressures for determining roof system deflections and whether a roof system passes or is “suspect”. Using ASTM E907, a roof system is “suspect” if the deflection measured during the test is 25 mm (about 1 inch) or greater.  Using FM 1-52, a roof system is “suspect” if the measured deflection is between ¼ of an inch and 15/16 of an inch, depending on the maximum test pressure; 1 inch where a thin cover board is used; or 2 inches where a thin cover board or flexible, mechanically attached insulation is used.  Test results' reliability  The reliability of the results derived from ASTM E907 and FM 1-52 is a concern, especially when the tests are used for quality assurance purposes. A note in ASTM E907 acknowledges its test viability. "Deflection due to negative pressure will potentially vary at different locations because of varying stiffness of the roof system assembly. Stiffness of a roof system assembly, including the deck, is influenced by the location of mechanical fasteners, thickness of insulation, stiffness of deck, and by the type, proximity, and rigidity of connections between the deck and framing system." For example, when testing an adhered roof system over a steel roof deck, placement of the test chamber relative to the deck supports (bar joists) can have a significant effect on the test results. If positioned between deck supports, the test chamber's deflection gauge will measure roof assembly deflection at the deck's midspan, which is the point of maximum deck deflection. Also, in many instances, field-uplift testing results in steel roof deck overstress and deck deflections far in excess of design values, which can result in roof system failure. These situations can result in false “suspect” determinations of a roof system. Industry position/recommendations Because of the known variability in test results using ASTM E907 and FM 1-52 and the lack of correlation between laboratory uplift-resistance testing and field-uplift testing, the roofing industry considers field-uplift testing to be inappropriate for use as a post-installation quality-assurance measure for membrane roof systems. Conclusion FM 1-52 is an FM Global-promulgated evaluation method and not a recognized industry-consensus test standard. The scope of FM 1-52 indicates that it’s only intended to confirm acceptable wind-uplift resistance on completed roof systems in hurricane-prone regions, where a partial blow-off has occurred, or where inferior roof system construction is suspected or known to be present. FM 1-52 was originally published by FM Global in October 1970. The negative-pressure uplift test was added in August 1980 and has been revised several times. The current edition is dated July 2012 and includes an option for "visual construction observation (VCO)" as an alternative to negative-pressure uplift testing. VCO provides for full-time, third-party monitoring to verify roof system installation is in accordance with contract documents. For more information, contact Craig Tyler.

LEED, Green Globes, and Living Building Challenge

For years, “going green” initiatives have been popping up in all aspects of our lives. In the construction industry, there are three main programs pushing buildings to be greener: LEED®, Green Globes, and Living Building Challenge (LBC). All three of these programs push for more sustainable buildings, but each takes a different approach to accomplish this goal. In this SpecTopics post, we will look at some of the differences between these three programs. Put simply, LEED and Green Globes are working toward making buildings more sustainable by improving existing standards, while LBC takes things a step further and promotes buildings that have little to no negative impact on the environment.  Overall Mission LEED wants to make buildings better for the environment, community, and those who use the building Green Globes wants to make buildings more environmentally efficient based on commonly valued environmental outcomes LBC promotes buildings that have a positive environmental impact   Certification Methods/Requirements  LEED  Points-based rating system (100 points possible)  Four levels of certification: Certified, Silver, Gold, and Platinum Green Globes  Points-based rating system (1,000 points possible)  Four levels of certification: 1 Globe, 2 Globes, 3 Globes, 4 Globes LBC  Seven petals (like those of a plant or flower) broken down into 20 imperatives; number of petals/imperatives completed determines award  Three awards are available (based on which path you take)  A Zero Carbon Certification and a Zero Energy Certification are available Main Points of Focus  LEED Location & Transportation, Sustainable Sites, Water Efficiency, Energy & Atmosphere, Material & Resources, Indoor Environmental Quality, Innovation, Regional Priority, and Integrative Process Green Globes Project Management, Site Energy, Water, Materials & Resources, Emissions, Indoor Environment LBC Place, Water, Energy, Health & Happiness, Materials, Equity, and Beauty
