ThermoSeal 2500 • Closed Cell Spray Foam Roofing & Insulation System

What is ThermoSeal 2500?

ThermoSeal 2500 is a two component, semi-rigid, high density, 2.5 lb closed cell polyurethane foam roong and insulation system which insulates, waterproofs, weatherproofs and air-seals your building’s exterior roof. Thermo- seal 2500 is intended for use by experienced, trained, certied polyurethane roong contractors. ThermoSeal 2500 is applied as a liquid spray which expands approximately 5 times its initial mass and cures within seconds into a semi-rigid mass. ThermoSeal 2500 provides a continuous monolithic surface without thermal breaks. The Thermo- seal 2500 roofing system is intended to be used with either Thermoseal Acrylic (ARC) or Thermoseal Silicone (SRC) roof coatings. The Thermoseal 2500 roong system provides a self-ashing, seamless roof system with superior wind uplift properties and is strong enough to endure roof foot trac. Thermoseal 2500 can be used in both retrot and new roong applications.
