SPC-10071 is a two-component, spray-applied open-cell polyurethane foam — a fully water-blown system with very low density (9–11 kg/m³), open-cell structure and B3 flame retardancy. It uses water as the blowing agent, so it produces no ozone-damaging gases and replaces traditional F-11 / HCFC-141B agents. The result is a lightweight, breathable foam that delivers thermal insulation, an air barrier, moisture control and excellent sound absorption — for a quieter, healthier, more energy-efficient interior.

Key Features

Ultra-light open cells
9–11 kg/m³ — far lighter than closed-cell, ideal for large interior areas at low cost.
Excellent sound absorption
Open-cell structure traps air and dampens noise for quieter rooms.
Water-blown & eco-friendly
No F-11 / HCFC-141B, no ozone-damaging gases — a low-carbon building material.
Thermal & air barrier
Insulates and seals air leaks while letting walls breathe.
Fast on-site cure
Cream 3–5 s, gel 6–10 s — sprays and rises in seconds.
Seamless coverage
Fills cavities and contours with no joints or thermal bridges.

Applications

Open-cell spray foam wall sound and thermal insulation
Interior Walls & Partitions
SPC-10071 open-cell spray polyurethane foam interior application
Ceilings & Lofts
Open-cell polyurethane spray foam material texture
Acoustic / Sound-Proofing
Open-cell spray foam insulation in building construction
Residential Construction

Best for interior walls, ceilings, lofts, partitions and acoustic treatment where light weight, sound absorption and breathability matter. For high-R, moisture-resistant, structural insulation choose our closed-cell spray foam (SPC-10072).

Frequently Asked Questions

Why choose open-cell over closed-cell?Open-cell SPC-10071 is much lighter (9–11 kg/m³), cheaper to cover large areas, breathable and an excellent sound absorber — ideal for interior walls, ceilings and acoustic work. Closed-cell suits high R-value and moisture-barrier needs.
What blowing agent does it use?Water only — no F-11 or HCFC-141B, no ozone-damaging gases. It is an eco-friendly, low-carbon foam.
How is it applied?Sprayed on site as a two-component (1:1 volume) system with standard plural-component spray equipment; it creams in 3–5 s and gels in 6–10 s.
Do you supply spray equipment too?Yes — matched spray-foam machines and application support are available. We reply within 24 hours.
