The project will use the Rmax ECOMAXci Wall Solution to provide Polyiso Continuous Insulation (CI) in the walls along with specialty windows to enhance this unique re-development effort.  

Originally built in the 1940’s as one of the last of the large tobacco auction warehouses, this space will now include 246 luxury rental apartments and 24,693 square-feet of retail space. The ECOMAXci Wall Solution is an NFPA 285 approved assembly, providing continuous insulation to eliminate thermal bridging through the steel studs, and an integrated air, water and vapor barrier to improve performance, lower costs, and reduce environmental impact.

Insulation Fly-In: Building Relationships for Better Buildings

Posted By PIMA

In this age of instant connectivity, virtual encounters allow communication and cooperation with unprecedented speed and ease. But there’s something about a face-to-face meeting that really helps people reach common ground. In May, 110 contractors, manufacturers, and suppliers from the insulation industry representing the majority of states met on Capitol Hill with lawmakers to discuss issues and ideas for harnessing the resources of the insulation industry to tackle some of our country’s most pressing problems. And they were serious about building those face-to-face relationships—and packed in 101 meetings on Capitol Hill, 23 of them with members of Congress. 

With the constant stream of news stories highlighting the human costs and economic consequences of a changing environment, momentum is growing behind solutions that can address these environmental challenges in ways that strengthen U.S. economic productivity and competitiveness. To that end, PIMA members are working to build enthusiasm for federal action on policies that optimize the energy efficiency of new and existing buildings. Raising standards for new residential, commercial, and industrial buildings and retrofitting older ones can lead to long-term savings through better building performance.

Increasing the energy efficiency of our buildings is a practical way to help the environment, create jobs, and save money. Boosting energy efficiency alone can provide 40% of the necessary greenhouse gas emissions reductions to meet global targets and the work to implement these standards will lead to jobs in manufacturing, distribution, and installation. These improvements will save consumers billions of dollars in energy costs annually – money that can be invested back into the U.S. economy.

But these policies would do more than save energy; they’d also provide buildings and the people who use them with added protection from severe weather events. In 2017 alone, there were $317 billion in losses from US natural disasters, jump-starting discussions on creating more resilient buildings and communities. Optimizing insulation for an energy efficient building envelope improves performance post-disaster or during prolonged events like heat waves or extreme cold. And the investment would pay off – it’s estimated that designing buildings to the 2018 I-Codes would deliver a national benefit of $11 for every $1 invested.  

Some legislative tools to promote these improvements include:

  • Strengthening oversight of new rules for disaster preparedness and response.

  • Supporting investments in building science research.

  • Recognizing buildings as infrastructure, including critical structures such as hospitals and schools.

Improving the energy efficiency and resilience of our built environment is a proactive approach to reduce greenhouse gas emissions while boosting economic growth, improving energy security, and advancing U.S. global competitiveness. PIMA members are working together to promote policies that support these goals through events like Insulation Industry National Policy Conference.

The Overarching Impact of the Insulation Industry

Posted By PIMA

Insulation can be found in buildings, refrigeration and a multitude of other end use products, and is used for floatation and transportation. From an environmental standpoint, when insulation products such as Polyiso are used in building and construction, the purpose of the insulation is to stop the flow of air (hot or cold) through the exterior walls and roofs of a building. Reducing the air transfer reduces the amount of energy required to regulate a building’s heating and cooling system. As a result, the insulation has a direct impact on the cost and use of energy to run that building.

Beyond its sustainability and environmental attributes, a new report, “The Contributions Insulation to the U.S. Economy in 2018,” produced by the American Chemistry Council (ACC), shows that the insulation industry contributes significantly to the U.S. economy. In fact, the industry generates more than 550,000 jobs and $33 billion a year in payrolls. For extended details on the economic contributions, insulation industry segments, and more view the full study here.

Polyiso Fire Performance

Posted By  PIMA

All construction materials, including insulation products like polyiso, must provide a suitable margin of fire safety. Polyiso insulation products are tested per material-specific tests as well as part of full assemblies that test fire performance as constructed. Importantly, polyiso possesses a high level of inherent fire resistance when compared to other insulations due to its unique structure of strong chemical bonds. These bonds result in improved high temperature resistance (up to 390 degrees F – more than twice the temperature resistance of some other building insulation products), which in turn leads to enhanced fire resistance. In addition, polyiso does not melt or drip when exposed to flame. The product forms a protective surface char that enhances its fire resistance in terms of reduced flame spread and the potential to contribute to flashover.

Roofing Day

Posted by PIMA

On April 4, 2019, as spring unfolded in Washington, D.C. with the arrival of the cherry blossoms, PIMA and a sea of more than 400 roofing industry professionals descended on Capitol Hill for meetings with Congressional representatives to discuss issues of importance to the entire roofing industry. PIMA and its member companies were there to advocate in support of three key issues:

  • A robust buildings component for infrastructure legislation.

  • Immigration reform that meets the roofing industry's workforce needs.

  • Expanded workforce training incentives.

There is strength in numbers and Roofing Day is an opportunity for the entire roofing industry to speak with one unified voice. Groups of roofing contractors, front-line workers, state and regional roofing associations, roofing manufacturers, distributors, and design and roof-consulting professionals participated in close to 300 Congressional meetings. Roofing Day 2019 had an increased participation of 5 percent compared to Roofing Day 2018. 

Visiting Capitol Hill with hundreds of roofing industry professionals was powerful as were the connections that were made. Equally as powerful and valuable - the connections made among the attendees.


Storage and Handling Recommendations For Polyiso Roof Insulation

Posted by PIMA

While it has been a long winter, spring is sure to get here sooner than we think, which means many roofing project will soon be underway. Here are key considerations (TB109) about the storage and handling of polyiso roof insulation on a job site:

Storage 
Polyiso insulation is typically shipped protected by a plastic wrap, plastic bag or both. This factory packaging is intended for handling the polyiso in the manufacturing plant and during transit; it should not be relied upon as protection at jobsites or other outdoor storage locations unless specified otherwise by the manufacturer. 

Material delivery should be carefully coordinated with the roof application schedule to minimize outdoor storage. When short-term outdoor storage is necessary, whether at grade or on the roof deck, the following precautions should be observed: 

  • Bundles should be stored flat above the ground utilizing included feet or on raised pallets. If possible, the bundles should be placed on a finished surface such as gravel, pavement, or concrete rather than on dirt or grass.

  • Unless specified otherwise by the manufacturer, cover the package and pallet with a waterproof cover, and secure to prevent wind displacement. 

Note: Polyiso insulation is fully cured and fit for installation upon delivery. No additional storage time is required.

Handling 
Exercise care during handling of polyiso insulation to prevent breaking or crushing of the square edges and surfaces. Remove the polyiso bundles from trucks with proper equipment. Other means of mishandling, such as pushing pallets off the edge of the truck or “rolling” the pallet across the roof deck, must be avoided. 

Product Application 
Polyiso should always be installed on dry, clean roof decks in dry conditions. Follow the manufacturer’s recommendations regarding product application to ensure performance to the intended design life of the roofing system. Apply only as much polyiso roof insulation as can be covered by completed roofing the same day. 

Construction Traffic 
Avoid excessive traffic during roof construction of or on a completed roof surface. Although polyiso has been designed to withstand limited foot traffic, protection from damage by construction traffic and/or abuse is extremely important. Roof surface protection such as plywood should be used in areas where storage and staging are planned and heavy or repeated traffic is anticipated during or after installation. 

Some designers and membrane manufacturers specify the use of cover boards as a means of protecting the insulation. If specified, installers should ensure that the cover board used is compatible with all components of the roofing system, is acceptable to the membrane manufacturer, and meets specified fire, wind, and code requirements. 

Polyiso roof insulation, like other roofing materials, requires a proper understanding of storage, handling, and application to result in a properly constructed roof system. You can find additional technical information about polyiso roof and wall insulation at polyiso.org.

NFPA 285

Posted By Nathan Pobre, PIMA

Improvements to the building envelope through the use of continuous insulation solutions have played a major role in mainstreaming high-performance construction practices that meet the requirements of commercial building energy codes. To meet the demands of today’s builds, architectural and design professionals must balance energy efficiency with whole building performance considerations, including fire safety. With respect to wall assemblies in Type I-IV Construction, understanding and properly implementing NFPA 285 can be a critical component for designing a compliant, high-performance building envelope.

NFPA 285 is a fire test standard that measures the flammability characteristics of exterior wall assemblies. More specifically, and according to the National Fire Protection Association (NFPA), it “provides a standardized fire test procedure for evaluating the suitability of exterior, non-load bearing wall assemblies and panels used as components of curtain wall assemblies that are constructed using combustible materials or that incorporate combustible components for installation on buildings where the exterior walls are required to be non-combustible.” While the individual products used in the wall assembly carry product-specific fire tests, it is important that entire wall assemblies are tested to meet approved fire performance requirements and ensure the safety of the building occupants.

The NFPA 285 test is performed on both load-bearing and non-load-bearing wall assemblies. It requires a wall assembly mockup spanning two stories (18’ high) with a test room on each floor. A single window opening is provided in the first-story room where a test burner is located. This burner is ignited in order to simulate an interior room fire. A second burner located on the exterior side of the test wall further enhances the flames to the window header. The test simulates a common, real-world interior fire scenario that reaches flashover, breaches a window, and spreads upward along the wall face. The test examines fire performance of the entire wall assembly, including within the wall assembly. It’s important to note also that the test is conducted without any interior fire suppression system.

To pass the NFPA 285 test, flame propagation cannot occur on or within the wall assembly beyond a certain distance either vertically or laterally from the area of flame plume impingement. Thermocouples are placed throughout the wall assembly to measure temperatures. Exceeding defined temperature limits results in a test failure. Additional requirements include: 

  • No flame propagation in second-floor room;

  • The inside wall assembly thermocouples shall not exceed 1000°F rise during the 30-minute test;

  • External flames shall not reach 10′ above the top of the window; and

  • The external flame shall not reach 5′ laterally from the center line of the window. 

It is a common misconception that only foam insulation products trigger NFPA 285. While any wall containing foam plastic insulation in Types I-IV Construction must comply with the test requirements, the use of other wall assembly configurations may also need to pass NFPA 285. These assemblies can include those constructed with combustible claddings and weather resistant barriers.

Since 2000, NFPA 285 has been in the International Building Code (IBC) and has gained attention due to the increased diversity in exterior wall systems and greater compliance with building energy efficiency standards. To learn more about NFPA 285, please refer to the National Fire Protection Association.

Polyiso Continuous Insulation

Posted By PIMA

Improvements to model energy codes are boosting advances in the use of insulation for commercial and residential building envelopes. Continuous insulation (CI) is quickly becoming the standard for high-performance building due to its ability to greatly improve operational performance while simplifying design and installation. In the ASHRAE 90.1 standard, Energy Standard for Buildings Except Low-rise Residential Buildings, CI is defined as: "Insulation that is continuous across all structural members without thermal bridges other than fasteners and service openings. It is installed on the interior, exterior, or is integral to any opaque surface of the building envelope."

CI is one of the most thermally efficient ways of complying with modern energy codes and mitigates energy loss that commonly results from thermal bridging. A thermal bridge, also called a cold bridge, heat bridge, or thermal bypass, is an area with higher thermal conductivity than the surrounding materials—like the studs of a wall that have batt insulation between them, creating a path of least resistance for heat transfer. In an otherwise insulated building, thermal bridges can account for up to 30 percent of energy loss. Using CI, the insulation doesn’t skip over studs or other obstructions in the wall cavity; it covers the entire surface. This results in:

  • Increased thermal performance 
    By blocking thermal bridging, a continuous insulation system increases the overall thermal performance of a wall assembly and a building. 

  • Reduced operating costs 
    Continuous insulation keeps energy and heat loss to a minimum, increasing the building’s energy efficiency and leading to lower monthly operating costs.

  • Reduced air infiltration and exfiltration 
    Continuous insulation with taped or sealed joints restricts air movement through the wall, helping to further reduce building heat loss.

The benefits of certain CI solutions go beyond enhanced energy efficiency. For example, polyiso insulation can serve as an air barrier, water resistant barrier, and water vapor control/retarder in wall assemblies. These capabilities provide the following additional benefits: 

  • Reduced risk of water condensation and moisture intrusion 
    Continuous insulation is a very moisture-resistant system, guarding the thermal and structural performance of the building. 

  • Efficient installation 
    When used as sheathing, continuous insulation can simplify the steps to construct a code-compliant wall assembly. 

  • Dimensional Stability 
    Polyiso insulation has excellent dimensional stability and meets ASTM C1289 Standard Specification for Faced Rigid Cellular Polyisocyanurate Thermal Insulation Board. 

There are a multitude of building envelope product options, and a variety of design and construction methods used for achieving compliance with code requirements for the thermal envelope. To learn more about polyiso CI systems and their tried and true methods to meet these requirements refer to PIMA Technical Bulletin #403: “Continuous Insulation Using Polyiso Wall Sheathing” and this AIA CEU course which covers:

  • The different roles a product can play in the building envelope to simplify its design.

  • The code requirements for buildings classified as International Building Code Type I-IV Construction.

  • Strategies for achieving code compliance.

  • How polyiso can play multiple roles to meet or exceed these code requirements.

Newest Shiloh House in Colorado Uses Polyiso Wall Boards for Superior Thermal and Weather Barrier

Posted By PIMA

When Colorado architects from the Davis Partnership were designing a new building for the non-profit Shiloh House, they were thrilled to find a product that would protect the building envelope from exposure to fire, water, and wind while integrating a continuous insulation system that would provide long-term thermal efficiency. The polyiso wall insulation solution from Rmax gave them flexibility to use a variety of external claddings for visual interest without compromising on protection from the elements and energy savings. Even better, with the help of Rmax’s in-house architect and field team, they were able to design a wall system with smooth, on-time installation that meet the rigorous NFPA 285 requirements.

Shiloh House has five locations across Colorado that offer nurturing, therapeutic and educational services aimed to help youth and families to overcome the impact of abuse, neglect and trauma. They helped over 1,000 youth last year alone. 

This new facility in Centennial is situated on a 1.54-acre property and includes on-site parking, outdoor courtyards, and the spaces and amenities that support the group’s programming to promote family stability and help families achieve their goals, while ensuring continued access to community resources once Shiloh House services have been successfully completed.

For an organization with such lofty goals, every dollar saved in building operations is another resource that can be used to serve its mission. The Rmax polyiso wall boards provide continuous insulation—eliminating heat lost that could occur through the studs when insulating with traditional products that are installed only in the wall cavities—and have reinforced aluminum foil facers that offer enhanced durability, dimensional stability and greater radiant heat protection. They make it easier and less expensive to keep the building comfortable, no matter the weather conditions outside.

“When we’re designing a building, we try to meet the highest standards because we care about protecting the environment and saving our client money over the whole life of their building by maximizing energy efficiency,” the architects explained. “With a reliable weather barrier and superior insulative properties, the polyiso continuous insulation system really gives your building the best protection while actually saving time and hassle on installation since it includes multiple protective layers in a single product.” 

And the finished product speaks for itself:
