Concrete Structure Spray Foam Applications

Large structures are often built using reinforced concrete to form the floors, walls and ceilings of the building. Regardless of their size, insulation is an important consideration to manage thermal performance, anti-condensation and soundproofing.

Using pre-manufactured insulation products such as PIR is labour intensive and can delay the construction timeline. Spray foam insulation can significantly speed up this process, helping you to stay ahead of your schedule whilst allowing other trades to continue work.

Spray-foam can be applied to virtually any concrete structure, these are some of the most popular applications that have benefited from having ThermoFoam installed.


Insulation

Underground Carparks
These below ground-level areas are usually situated underneath a building. It is vital that underground car-parks are adequately insulated to prevent heat loss from the structure above and ensure the subterranean level remains dry.

Often used as an entry point into the building above for pipework and other fixings, this can make the use of pre-manufactured insulation, such as PIR sheets, difficult to install effectively.

Spray-foam insulation can help to provide a seamless thermal barrier in the trickiest of spaces, particularly where other fixings are in-situ or the concrete ceiling is curved or corrugated. The speed of application of spray-foam surpasses any other alternative, helping you to minimise disruption to the building whilst maximising the thermal barrier.

Due to its performance as an effective vapour barrier, we recommend the application of ThermoFoam Closed-Cell to an underground carpark with the depth determined by the required U-Value.

Soffits
Concrete soffits form the ceiling or roof area of a structure. These areas are often vast in size and can become very warm in the summer but freezing cold in winter months.

When heat from within the building rises against the cold concrete slab, there is the risk of condensation. This can have a long-term detrimental effect on the building and it’s occupants when inadequately insulated.

Additionally, in large scale projects, using traditional insulation products like PIR requires the provision of an air-gap. This can cause fire safety concerns as it allows the flame to spread rapidly between the insulation and concrete soffit.

Spray foam insulation is one of the most effective choices in eliminating condensation. It also benefits from not requiring the provision of an air-gap as it forms a part of the substrate on which its applied, leaving no opportunity for moisture to become trapped.

The speed of application of both our Open Cell and Closed Cell spray foams make it a suitable solution for insulating concrete soffits.

Whilst both options provide exceptional thermal performance, ThermoFoam Open Cell helps to reduce the effects of noise transmission. Alternatively ThermoFoam Closed Cell can add structural integrity.

Between Floors
The insulation requirements between the floors of a concrete structure should be considered if the building is to have multiple occupants, each responsible for their own heating costs.

Regardless of the requirements to insulate, concrete floors should always provide for good soundproofing to avoid the impact of noise transmission through the building.

As an alternative to the use of a fibre-based material to provide soundproofing, Open-cell spray foam is a low density insulator that not only reduces the impact of noise transmission but also offers great thermal performance.

We recommend an application of ThermoFoam Open-Cell spray foam at around 200-300mm for effective sound absorption and an increased barrier against heat-loss between floors.


Open-Cell vs Closed-Cell
(In moisture rich environments)

Although we install both open and closed-cell products, not all spray foams are created equal, therefore we are always careful to respect the application uses for both products in achieving the correct install for your building.


We approached ThermoFoam because we needed a solution that was unfamiliar with us. From initial meeting to completion of installation, ThermoFoam were able to talk about their product with authority which helped to fill us with confidence that the chosen solution was right
