Easy Installation, Lifelong Efficiency

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.

Sealection 500 is a spray-applied adhesive, which once applied, expands in place using water-blown technology, without CFCs, HCFCs, or ozone-depleting chemicals. Unlike traditional fiberglass insulation, Sealection 500 will maintain its performance; time and temperature have no effect on the spray foam insulation's R-value of 3.81 at 1 inch. Sealection 500 never deteriorates or decomposes. The product retains its shape and half-pound density over time, and never settles or compacts.

Benefits of Sealection 500

  • 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
