Sealection® 500

Sealection® 500 has been Demilec’s flagship product for more than 20 years, and has positioned Demilec as an industry-leading spray foam insulation manufacturer. As an environmentally-friendly product, it delivers superior performance, energy savings, and is an excellent return on investment for architects, builders, contractors, and homeowners, making it the ideal choice for insulation.

Sealection 500 is a cutting-edge formula of open-cell spray foam insulation, which expands 120 times its liquid volume to insulate and seal all cracks, gaps, and joints with a single application, and is easy to install and finish. It has dramatically increased energy efficiency for millions of residential and commercial property owners. This translates to a high-performing product for builders, shorter application, and finishing times for contractors, and lower energy bills for homeowners and commercial building owners.

  • Contains no ozone-depleting chemicals, gases, fibers, or asbestos
  • Changes the building envelope design, which allows builders and contractors to right-size HVAC systems, which typically results in using smaller HVAC systems
  • Cuts heating and cooling costs as much as 50 percent*
  • Minimizes outside noise, as airborne noise can no longer easily pass through walls
  • Less dust and allergens enter the environment due to the airtight seal
  • Maintains peak performance; it never deteriorates or decomposes

Sealection 500 is in compliance with the International Building Code® (IBC), the International Residential Code® (IRC), and the International Energy Conservation Code® (IECC).

Sealection 500 is also an NAHB Research Center Green Approved Product and an Eco Logo Certified Green Product.


Agribalance® merges our high-performing, open-cell spray foam insulation with natural, renewable oils. This allows architects, builders, contractors, and homeowners to achieve new standards of performance, quality, and energy efficiency.

This high R-value of 4.45 at 1 inch, polyurethane insulation expands to seal cracks, gaps, and voids in attics, walls, crawl spaces, and ceilings. Agribalance is a three-quarter pound density foam that reduces air leakage by improving energy efficiency, and reducing moisture intrusion and outside contaminants such as dust, dirt, and allergens. As a result, builders can generally install smaller, more energy-efficient HVAC systems and achieve similar, or superior comfort compared to traditionally insulated structures which require a larger, less efficient HVAC system – resulting in higher energy costs.

Since it tightly bonds to surfaces in the attic, ceiling, and walls, extraneous noise is also minimized.

  • Developed with 20% of Agri-based, renewable materials
  • Decreases dust and air pollutants
  • Maximizes energy efficiency
  • Minimizes noise disturbance
  • Contains no ozone-depleting chemicals, gases, fibers, or asbestos

Agribalance is in compliance with the International Building Code® (IBC), the International Residential Code® (IRC), and the International Energy Conservation Code® (IECC).

Agribalance is also a USDA Bio-Preferred Product and an NAHB Research Center Green Approved Product.

Heatlok HFO High Lift

Spray up to an R-49 in a single pass!

Heatlok HFO High Lift, Demilec’s first product to leverage ultra-low global warming potential blowing agent, combines an R-value of 7.5 with a 6.5” lift to achieve an R-49 in a single pass. Spray IRC ceiling insulation code in less time than ever before.

Heatlok HFO High Lift leverages Honeywell’s Solstice® Liquid Blowing Agent technology, which has a GWP of 1, 99.9% lower than traditional blowing agents. In compliance with the Montreal Protocol designed to lower the use of global warming potential gasses, Heatlok HFO High Lift combines all of the benefits of Heatlok with the industries fourth generation of blowing agent.

  • R-value = 7.5/inch*
  • Spray 6.5” (R-49) in one pass
  • Low VOC emission, meets requirements for schools and healthcare facilities
  • Superior yield, sprayability, adhesion, and reduced gun clogging
  • Formulated with Solstice® Liquid Blowing Agent’s ultra-low GWP of 1

*Aged R-value at 4 inches per ASTM C518
