Open Cell Spray Foam Insulation
Open cell spray foam insulation for commercial, industrial and agricultural buildings, outbuildings and containers across Walsall and the West Midlands. Fully insured, 10-year guarantee. Free survey.
Cost-Effective Open Cell Foam for Non-Domestic Buildings
Open cell spray foam is a lightweight, economical insulation for warm, dry, enclosed spaces. As it is applied it expands rapidly to many times its liquid volume, filling every gap, joint and cavity and forming a continuous, draught-free layer that ordinary boards and rolls cannot match. We install open cell spray foam in commercial, industrial and agricultural buildings across Walsall and the West Midlands.
Its open, spongy cell structure gives excellent thermal performance for the money, along with useful sound absorption — a real benefit in offices, studios and workspaces. Because it is soft and flexible, it copes well with the movement and vibration found in framed buildings and lightweight structures.
Ideal Applications
Open cell foam is well suited to:
- Commercial units and offices — warm, dry interiors where running-cost savings matter
- Garden rooms, garden offices and studios — comfortable, quiet workspaces year-round
- Timber-framed outbuildings — following the frame exactly for a complete seal
- Internal walls and ceilings of non-domestic buildings — thermal and acoustic control
For buildings exposed to moisture, or where added strength or a higher insulation value per millimetre is needed, closed cell spray foam is usually the better option. We will advise which is right at survey.
What You Gain
- Lower heating costs from a continuous, gap-free thermal layer
- A quieter space thanks to the foam’s sound-absorbing structure
- Fast installation, usually completed in a single visit with little disruption
- A 10-year guarantee, fully insured, from a hands-on local team

Frequently Asked Questions
Open cell foam suits warm, dry, enclosed non-domestic spaces — office units, garden rooms and studios, and the interiors of commercial buildings where cost-effective thermal insulation and sound dampening matter more than moisture resistance.
No. Spray foam insulation is no longer installed in domestic residential properties. Open cell foam is fitted only in commercial, industrial, agricultural and similar non-domestic buildings and structures.
Open cell is lighter, softer and more economical, with a spongier structure that is excellent for warmth and acoustics. Closed cell is denser, rigid, moisture-resistant and adds strength. We recommend the right one for your building at survey.
