Henry No-Mix Open Cell Foam

Simple, Sustainable Spray Foam Insulation

No-Mix Open Cell Foam is a two-component, light-density polyurethane spray foam formulated for residential use. With a true 1:1 mix ratio and no pre-mixing or agitation required, it’s engineered for simplicity and speed on the job site. The system includes Component A (ISO) and Component B (RESIN) – a blended formula free from ozone-depleting blowing agents, and made with built-in catalysts, polyols, and fire retardants.

Designed to replace traditional insulation like fiberglass or cellulose, No-Mix is ideal for exterior and interior walls, vented and unvented attic assemblies, ceilings and floors.
