The Vega Bond Closed Cell Spray Foam Insulation Kit (Slow Rise Series) is a slow rise injection foam system engineered for existing wall cavities. Designed for drill-and-fill applications behind plaster or drywall, this closed cell formula is ideal for upgrading insulation in older homes and structures without removing finished walls.
Designed for Existing Walls & Enclosed Cavities
The slow rise formulation allows the foam to flow into enclosed and hard-to-reach areas before curing, supporting even distribution inside wall cavities. The foam becomes tack-free in approximately 3 minutes, giving it time to reach far-off areas before setting.
Important: This product is not intended for open wall applications. When sprayed on open surfaces, the foam may run before curing. It is specifically designed for existing walls and enclosed cavities only.
- Slow Rise Injection Foam for Existing Walls – Closed cell spray foam designed for drill-and-fill applications behind plaster or drywall. Ideal for insulating enclosed wall cavities in older homes and retrofit projects without removing finished walls. Drill injection holes on closed wall cavities and let the foam expand slowly.
- Controlled Expansion for Uniform Coverage – Slow rise formula allows the foam to travel into hard-to-reach and enclosed areas before curing. Becomes tack-free in approximately 3 minutes to support even distribution inside wall cavities.
- High-Performance Closed Cell Insulation – Delivers an R-value of R-7 per inch to help improve thermal efficiency. Helps seal air leaks while reducing dust infiltration, sound transfer, and moisture intrusion.
- Certified Fire Performance – ASTM E84 Class A building material with low flame spread and minimal smoke development, supporting use in residential and commercial insulation applications.
