Virtually every aspect of today’s residential building involves the application of sophisticated building science to achieve better performing homes that are durable, energy-efficient, cost-effective and code compliant. This current era of building science-driven innovation can also usher in some uncertainty as to which product and material selections will help achieve high-performance homes without compromising jobsite efficiency and profitability.
A high-performance home is greater than the sum of its parts. Simply selecting category leading products will not automatically achieve the desired end product. In today’s sophisticated building environment, it remains critical for builders to avoid product interactions that can negatively impact the performance of other materials in the assembly.
To help navigate through this changing landscape, builders can consider adopting a multi-dimensional set of criteria to assess their options and enable confident product decisions. Investing the time to evaluate the best choice of materials for the job can save a lot of headaches—and callbacks—down the road.
Let’s take a look at how fiberglass insulation measures up in five key categories including performance, installation, safety, environmental impact and accountability, to illustrate why a cross-category product review can prove beneficial and profitable.
When it comes to performance, fiberglass represents one of the most cost-effective ways to insulate homes, protect against heat loss and provide superior moisture resistance.
In fact, extensive research from the Building Science Corporation has shown that once a building is sealed, R-value is what matters most for thermal performance—not insulation type. A comprehensive air infiltration study, conducted by the Owens Corning Building Science team, also found that the majority of air leakage occurs at joints, not in framing cavities where most insulation is installed.
Builders who strive to build better can trust the research that has consistently shown fiberglass insulation to provide excellent thermal performance and moisture control.
The key to success in any insulation installation is doing it right the first time. As a result, installation represents another important category to evaluate when making product decisions.
Fiberglass insulation is easy to measure, cut and install and the jobsite can stay open to all trades during and following installation. While various insulation choices exist, fiberglass batts remain an effective, economical and efficient option for consistently achieving Grade 1 installations.
The ease of installation with fiberglass insulation also directly correlates to creating a jobsite that can protect installers from unnecessary hazards and safety risks on the job.

Working with fiberglass offers builders the ability to eliminate risks with a proven solution that performs.
Building science innovation has also driven advancements that make fiberglass insulation a sustainable solution.
In addition to recycled content, builders can also look to life cycle assessment as the recognized industry standard for determining the relative sustainability benefits of product choices.
As builders continue to factor environmental impact into their jobs, fiberglass insulation can deliver long-term sustainable and responsible solutions.
To help minimize potential for field failures, manufacturers like Owens Corning control the quality and performance of products from design through manufacturing, and maintain a close relationship with builders, contractors and consumers.
As a result, widely-studied fiberglass insulation continues to represent a safe building material that incorporates leading building science innovation and delivers a highly adaptable solution that contributes to the overall comfort, energy efficiency and performance of the home.
Remaining informed about how key building products, like insulation, perform across each of these categories will enable better building today and into the future.
Industry leaders join to create complete
masonry cavity wall system
Five construction companies have aligned to create a complete masonry cavity wall system. Owens Corning worked closely with industry leaders and their products to create a completely compatible, code-compliant and warrantied system. The CavityComplete Wall System for Steel Stud with Masonry Veneer makes it easier to specify and detail an assembly with components that are tested and proven to work together. The system includes components from Owens Corning Sales LLC, Heckmann Building Products Inc., Mortar Net Solutions, Rodenhouse Inc. and Tremco Inc. The wall system was introduced at this year’s AIA National Convention in Chicago.
This collaborative product was designed to take the guesswork out of specifying, says said Greg Mather, vice president and general manager of Foam Insulation Systems at Owens Corning. “Working with the industry leaders, we have jointly created and warrantied this wall system to work together as a whole with proven products that are trusted by architects and specifiers.”
Owens Corning spearheaded this system with companies that have similar quality, performance and safety standards to ensure the wall system parts would function as a whole, including:
- Foamular 250 Extruded Polystyrene (XPS) Rigid Foam Insulation for continuous insulation, EcoTouch Flame Spread 25 and EcoTouch Pink Fiberglas cavity insulation.
- Tremco ExoAir 230 Vapor-Permeable Air Barrier, ExoAir TWF Thru-Wall Flashing Self-Adhering Membrane, Dymonic 100 Polyurethane Sealant and TREMstop Smoke and Fire Sealant.
- Rodenhouse Thermal-Grip CI prong washers with Grip-Deck screws for continuous insulation and Thermal-Grip brick-tie washers for veneer anchors.
- Heckmann Building Products Pos-i-Tie masonry veneer anchoring system, with the Pos-i-Tie ThermalClip and pintle wire tie.
- Mortar Net Solutions Multi-plane drainage system featuring the TotalFlash integrated drainage solution and the MortarNet with insect barrier mortar dropping collection device.
Owens Corning Thermafiber Safing Insulation for perimeter joint fire containment, when building codes require it.
Industry experts agree that an integrated wall system will help solve many of the specification and installation problems they encounter on a daily basis.
“Architects are always looking for ways to improve the performance of their exterior wall assemblies and CavityComplete Wall System for Steel Stud with Masonry Veneer helps make the complicated process more predictable by leveraging the knowledge of multiple product manufacturers,” says Mark Kalin, FAIA, FCSI, president of Kalin Associates. “The … wall system provides documentation that architects can submit to building officials demonstrating that the assembly meets mandatory building code fire containment, air leakage, water penetration and thermal resistance requirements.”
