Spray-Applied Thermal & Acoustic Insulation for Commercial Projects
Spray-applied thermal-acoustic insulation is a fibreglass-based material sprayed directly onto concrete, steel or wood to insulate and absorb sound in a single, seamless layer. Western Insulation installs ThermaCoustic products on parkade ceilings, exposed decks and commercial and multi-unit buildings across Langley, Metro Vancouver and the Fraser Valley.

ThermaCoustic is made in Maple Ridge, BC, by ThermaCoustic Industries International. It bonds to concrete, steel and wood and can be applied over many existing surfaces. Because it’s sprayed rather than cut and fastened, it covers beams, decks, pipes and irregular shapes in one pass, without the gaps that boards and batts leave around obstacles.
Where Spray-Applied Thermal-Acoustic Insulation Is Used
- Parkade ceilings under heated suites or offices – keeps floors above warmer and cuts noise
- Multi-unit residential buildings – exposed decks, corridors, mechanical and garbage rooms
- Institutional buildings – schools, gyms and recreation centres with open-structure ceilings
- Commercial and industrial spaces – warehouses, workshops and retail with exposed decks
- Prefabricated metal buildings – reduces condensation and rain noise on metal roofs
- New construction and retrofits – sprayed onto existing structure without removing services
Advantages of Spray-Applied Thermal-Acoustic Insulation
Versatile application
Bonds to concrete, steel, wood and many primed surfaces, overhead or on walls.
Seamless coverage
One continuous layer around beams, pipes and fasteners – no joints for heat or sound to leak through.
Thermal efficiency
Adds R-value to exposed decks and slabs where batts and boards are hard to fit
Fast installation
Large areas are covered quickly from a single spray rig, with less cutting, fastening and waste.
Sound absorption
Absorbs echo and reverberation in parkades, gyms and open ceilings. The AF-90 finish is rated NRC 0.60 at 1/2 inch and NRC 0.90 at 1 inch.
Durable, fibreglass-based finish
Fibreglass-based rather than cellulose, and can be left exposed or covered depending on the design.

Exposed or Covered: Choosing a Finish
In parkades, warehouses and service areas the spray is usually left exposed, which saves the cost of a ceiling. Our installers tamp the surface for an even, clean look. In finished spaces, the AF-90 finish gives a textured acoustic ceiling, or the insulation can be covered by a ceiling system where the design calls for it.

Spray-Applied Thermal-Acoustic vs Other Options
Thermal-acoustic spray | Batts or boards | Spray foam | |
Irregular surfaces | Excellent – sprays around everything | Hard – cut and fasten | Good |
Sound absorption | High | Moderate (batts) | Low |
Exposed finish | Yes (with finish product) | No – must be covered | No – thermal barrier needed |
Best for | Parkades, decks, open ceilings | Framed walls and floors | Air sealing, rim joists, damp areas |

Frequently Asked Questions
What is spray-applied thermal-acoustic insulation?
It is a fibreglass-based insulation sprayed directly onto concrete, steel or wood, where it bonds and forms a seamless layer that both insulates and absorbs sound. It is used on parkade ceilings, exposed decks and open-structure ceilings in commercial, institutional and multi-unit buildings, often left exposed as the finished surface. For soundproofing inside a home or legal suite, see our soundproofing insulation.
Where is ThermaCoustic made?
ThermaCoustic Industries International Ltd. is based in Maple Ridge, BC. It makes TC-417, a fibreglass-based spray-in-place thermal and acoustic insulation, and AF-90 AcoustiFinish, a spray-applied acoustic ceiling and wall finish. Western Insulation installs these products for projects across Langley and the Lower Mainland.
Can it be left exposed?
Yes, in many applications. In parkades, warehouses, gyms and service areas the insulation is often left exposed with a tamped finish, which avoids the cost of a separate ceiling. Where appearance matters, a finish product such as AF-90 provides a textured acoustic ceiling. Your design and code requirements decide the final finish.
How much sound does it absorb?
Sound absorption is measured with the noise reduction coefficient (NRC), where 1.0 means almost all sound is absorbed. The AF-90 finish is rated about NRC 0.60 at half an inch and 0.90 at one inch. The right thickness depends on whether the goal is reducing echo, meeting a design target or adding thermal value.
Is it the right choice for a strata parkade?
Often, yes. Insulating the parkade ceiling under heated suites keeps floors above warmer and reduces noise from cars and doors, and the spray covers pipes and beams without cutting boards. We review the area, thickness and schedule with your council or property manager. See our strata and commercial insulation page.
