Owens Corning

Owens Corning is bringing the impermeable nature of FOAMGLAS cellular glass insulation to two new systems engineered to help mitigate corrosion under insulation (CUI). The resilient and redundant properties of cellular glass insulation help manage CUI in differing operational and environmental conditions, such as temperature, humidity and corrosive nature.     

With a primary objective in CUI mitigation being to help keep water out of the system, the composition of FOAMGLAS insulation is uniquely suited to the challenge. Made up of millions of hermetically sealed glass cells, it is impermeable to moisture in both liquid and vapor forms. 

FOAMGLAS Sealed System

The FOAMGLAS Sealed System is designed to help keep moisture out of the insulation system. Utilizing a new, low-viscosity, neutral-cure joint sealant (PITTSEAL Hi-Temp LV RTV), the FOAMGLAS Sealed System seals joints and compartmentalizes insulation system components to manage CUI risk.  

Compared to other systems that combine permeable insulation with a cladding or wrap, the FOAMGLAS Sealed System deploys its entire material thickness to serve as a seal against ingress of moisture. Applications include above ambient/cyclical, below ambient with a high vapor drive, and underground/direct-buried. 

FOAMGLAS Spacer System

The FOAMGLAS Spacer System utilizes proprietary technology to create an air gap between the cellular glass insulation and the pipe. Specified where water intrusion is probable from secondary sources, the system is favored in offshore and marine applications. Should water enter the system, the compartmentalized design channels moisture to drainage points in the system.  

Prefabricated to offer contractors a one-step solution and supported with compatible sealants and adhesives, the FOAMGLAS Spacer System supports heat-tracing configurations and delivers good acoustical properties.  

The choice of sealed or spacer to manage CUI risk provides engineers with flexibility to design a system equipped to the needs of the operating environment. 

While FOAMGLAS insulation brings new standards of CUI mitigation, it has long been trusted for its unique product characteristics, comprehensive technical support, and a long, distinguished history of success in a variety of commercial and industrial applications. 

“Impermeability, superior compressive strength, dimensional stability, fire-resistance, and a wide service temperature range are qualities that engineers recognize when specifying FOAMGLAS cellular glass insulation in critical applications around the world,said Brandon Stambaugh, director of product management, technical services and training. 

“The harmful consequences that CUI presents to various industries is well-documented,” he added. “The trusted performance of cellular glass insulation – combined with our compatible accessories – help provide engineers, contractors and ultimately owners, with an additional measure of confidence when it comes to designing a system to control CUI.” 

Owens Corning, Toledo, Ohio, provides innovative products and sustainable solutions that address energy efficiency, product safety, renewable energy, durable infrastructure, and labor productivity. Its three integrated businesses are dedicated to the manufacture and advancement of a broad range of insulation, roofing and fiberglass composite materials.
