Read below to learn more about each product as well as the science behind spray foam insulation.




Sealection Agribalance

General: SEALECTION® Agribalance has highest R-value per inch of any open-cell foam on the market: R-4.45. Given its benefits as an air barrier, it is a great combination of superb R-value and air barrier in an open-cell foam. Agribalance's unique formula also makes it one of the most environmentally friendly products on the market. With more than 20 percent renewable content, this insulation exceeds the government's minimum standard for renewable content and is rated as one of the highest Green insulation products on the market.

Recommended Applications: Open-cell foam is an excellent product for insulating in our mixed-humid climate as it is an air barrier but not a vapor retarder. Common applications are:

  • Wall cavities
  • Enclosed Floors
  • Cathedral ceilings
  • Underside of roof decks, in conjunction with an ignition barrier intumescent coating

This climate typically has higher humidity outdoors in the summer, and higher humidity indoors in the winter. This creates the potential for moisture flow from outside to inside the house in the summer, and from inside to outside the house in the winter. For this reason, a wall assembly that can dry out in both directions, rather than to be trapped by a vapor retarder, is a common sense approach in our area.

Sealection 500

General: For more than a decade, SEALECTION® 500 © has been the flagship product for Demilec (USA) LLC's line of industry-leading spray foam insulation products. It is an environmentally friendly, easy-to-apply insulation that delivers superior performance and money-saving benefits to builders, contractors, and homeowners. SEALECTION 500©'s polyurethane formula reduces energy loss by creating an airtight seal that expands into cracks, gaps and joints. This allows HVAC systems to heat and cool homes using smaller, right-sized units.

Recommended Applications: Open-cell foam is an excellent product for insulating in our mixed-humid climate as it is an air barrier but not a vapor retarder. Common applications are:

  • Wall cavities
  • Enclosed Floors
  • Cathedral ceilings
  • Underside of roof decks, in conjunction with an ignition barrier intumescent coating

This climate typically has higher humidity outdoors in the summer, and higher humidity indoors in the winter. This creates the potential for moisture flow from outside to inside the house in the summer, and from inside to outside the house in the winter. For this reason, a wall assembly that can dry out in both directions, rather than to be trapped by a vapor retarder, is a common sense approach in our area.

Demilec APX

General: Demilec APX is a revolutionary new foam that can be sprayed in attics and crawlspaces without an ignition barrier or coating. Demilec APX is one of the few products that is compliant with the stringent test requirements of the International Code Council, without the use of additional fire protection products. Addionally, Demilec APX provides all of the traditional benefits you expect from spray foam insulation including air sealing, lowering heating and cooling bills, helping reduce dust and allergens and contributing to a quieter indoor environment.

Recommended Applications: Open-cell foam is an excellent product for insulating in our mixed-humid climate as it is an air barrier but not a vapor retarder. Common applications are:

  • Floors over crawlspaces
  • Underside of roof decks over attics

When applied in these areas, Demilec APX does not need an additional ignition barrier. Please note that a thermal barrier, such as drywall, is always required to separate foam from a living space, including attics and crawlspaces uses for storage.
