What is ThermoSeal ONE?
ThermoSeal ONE is a two component, semi-rigid, medium density, 1.7 lb closed cell polyurethane foam insulation system which simultaneously insulates and air-seals your building structure. Thermoseal ONE requires the use of an “A” component (ISO) and a blended “B” component (RESIN), which contains ZERO ozone depleting catalysts, polyols and fire retarding materials. ThermoSeal ONE is designed to make homes more energy efficient, quieter, healthier and more comfortable. ThermoSeal ONE is applied as a liquid spray which expands approximately 15 times its initial mass and cures within seconds into a semi-rigid mass. ThermoSeal ONE fills all building cavities completely sealing all cracks, crevices, and voids where air loss and infiltration are most common.
Contractor & Applicator Benefits
With continuous research and development, ThermoSeal continues to lead the spray foam insulation industry in both quality and diversity of spray foam products. Our products insulation performance is the clear winner in energy savings, sound control, moisture vapor permeance, lifespan, and cellular structure, therefore reducing waste and cost at the same time.
Sprayability – Easy to spray with a more controlled rise, resulting in less waste
Predictability – Provides consistent & predictable yields
- Advantages – Vapor barrier, high-yield, passed appendix-X (No ignition barrier needed)
R-Value – One of the highest aged R-Values in the industry today
