Whether you’re dealing with noisy neighbours, heavy machinery, or the relentless heat of a Saudi summer, acoustic spray insulation offers a proven, all-in-one remedy. Unlike traditional batt or board insulation, spray-applied systems conform perfectly to any surface, including irregular cavities, curved ceilings, and complex steel structures, creating an airtight, sound-dampening barrier with zero gaps.

What Is Acoustic Spray Insulation?
Acoustic spray insulation is a liquid or semi-liquid insulating compound that is mechanically sprayed onto walls, ceilings, floors, and structural surfaces. Upon application, it expands, cures, and hardens into a dense, porous, or rigid layer, depending on the formulation, simultaneously reducing airborne sound, impact noise, and thermal transfer. Common types include open-cell polyurethane spray foam, closed-cell polyurethane spray foam, and spray-applied cellulose insulation.
How It Works
Acoustic spray insulation works through two core mechanisms: mass and absorption. When sprayed, the material fills every crack and cavity, adding mass to the structure, which blocks sound waves from passing through. Simultaneously, its porous cellular matrix absorbs sound energy, converting it into minute amounts of heat before it can reflect or transmit further. The result is a measurable improvement in Sound Transmission Class (STC) and Noise Reduction Coefficient (NRC) ratings.
Types of Acoustic Spray Insulation
1. Open-Cell Spray Foam: Lightweight, flexible, and highly porous. Excellent at absorbing mid- to high-frequency sound waves. Ideal for interior walls, studio spaces, and residential ceilings.
2. Closed-Cell Spray Foam: Dense, rigid, and moisture-resistant. Provides superior thermal performance alongside acoustic benefits. Preferred for exterior walls, basements, and industrial facilities.
3. Spray-Applied Cellulose: Eco-friendly, made from recycled paper fibre. Outstanding mid-frequency sound absorption with a lower carbon footprint. Common in green-certified buildings and sustainable construction projects.
4. Spray-Applied Mineral Wool (Rockwool): Fire-resistant and acoustically dense. Frequently used in commercial and high-rise construction in the Kingdom of Saudi Arabia.
Key Benefits of Acoustic Spray
✔ Superior Noise Reduction: Achieves STC ratings of 45–65, dramatically lowering noise between rooms, floors, and exterior environments.
✔ Thermal Efficiency: Reduces heat gain in KSA climates, lowering air-conditioning loads and cutting energy costs by up to 30%.
✔ Seamless Application: Conforms to any surface no gaps, no thermal bridges, no acoustic weak points.
✔ Moisture Resistance: Closed-cell variants act as a vapour barrier, preventing condensation and mould growth.
✔ Structural Reinforcement: Spray foam adheres to surfaces, adding racking strength and rigidity to walls and roofs.
✔ Fast Installation: Applied in hours, not days minimising project downtime and labour costs.
Applications of Acoustic Spray
Acoustic spray insulation is widely used across Saudi Arabia in residential villas, high-rise apartments, shopping malls, hospitals, industrial warehouses, mosques, recording studios, educational institutions, and data centres. With Gitco’s certified spray application teams, projects across Riyadh, Jeddah, Dammam, and the wider GCC benefit from internationally standardised installations backed by local expertise.
Comparison: Acoustic Spray vs Traditional Insulation
Acoustic Spray Insulation vs Batt Insulation: Unlike fibreglass batts that leave gaps at edges and corners, spray insulation expands to fill 100% of the cavity delivering consistently higher STC scores and eliminating acoustic flanking paths.
Acoustic Spray Insulation vs Rigid Board: Spray-applied systems eliminate the need for mechanical fasteners and adhesive, reducing installation complexity and potential future air leakage — critical in high-humidity coastal regions like Jeddah.
Maintenance & Longevity
Once cured, acoustic spray insulation requires virtually no maintenance. Polyurethane-based systems carry a service life exceeding 50 years under normal building conditions. Cellulose variants may settle marginally over time but retain 90%+ of original performance without re-application. Gitco provides post-installation inspection services to ensure long-term performance guarantees.
