ORNL researchers have developed a new method for producing thermoset foam insulation with improved processing and installation outcomes. The new material is a moldable dough with adjustable shape and viscosity, allowing for increased flexibility in production and application.  

Description 

Effective and affordable insulation is critical for facilitating comfortable and energy-efficient living spaces in nontemperate environments. Modern insulation is typically achieved using thermoset foam, which has evolved to be the cheapest and most easily producible and transportable material for this purpose.   

Traditional thermoset foam insulation is generally produced from molded panels or as a sprayable foam for direct application, but both methods suffer from important limitations. Prefabricated panels are limited in size and shape by expensive molds, while sprayable foam produces hazardous materials during application and requires specialized and costly equipment to install safely.  

The new material addresses both of these limitations. The dough can be molded into a variety of shapes before being cured to keep the desired structure. Once fully cured, the nontoxic material can be easily installed, requiring only nails or screws. 

Applications and Industries 

  • Building construction  
  • Temperature-controlled transportation  
  • Pipe insulation 

Benefits 

  • Greatly improved variability in shape and density  
  • Simple installation requires no specialized tools
