Suspended Ceilings
About Spray Foam For Suspended Ceilings
In many commercial office environments, suspended ceilings sit well below the roof line to create an uninsulated void.
Ever wondered how to insulate a roof when a suspended ceiling frame is sat below the void? Spray foam insulation offers an excellent solution to minimise down time for the office environment whilst providing long-term thermal performance.

Where to Use Spray Foam For Suspended Ceilings
Spray foam insulation offers an effective way to insulate otherwise difficult suspended ceiling voids. Where a suspended ceiling tile system prevents the use of traditional insulation materials, spray foam insulation can be installed using specialist access equipment. Either Sucraseal Open Cell or Nexseal LE Closed Cell are suitable for suspended ceiling voids depending on the roof structure. Generally, spray foam is installed to the underside of the roof substrate to protect the building envelope. This not only prevents heat loss from the habitable areas out through the roof, it also mitigates solar gain during summer months which can make the working environment under a suspended ceiling, unbearable!
What Is The Best Insulation For A Suspended Ceiling?
Traditional materials such as mineral wool could be laid on top of the suspended ceiling tiles but this will mean a person has to pop up through a series of tiles, carry rolls of mineral wool insulation and then reach in to lay it seamlessly across the top of the tiles. This process of installing insulation is possible but time-consuming, then there is the health and safety aspect of standing on a ladder, pushing the rolls of insulation up through the metal hanger system before balancing on the ladder and spreading it out. I’m sure you can imagine this to be difficult, laborious work and in any event, a layer of mineral wool may cover vital runs of electrical cables that usually run through the ceiling voids. Spray Foam Insulation is the very best way of tackling these types of projects and can speed up the process whilst minimising disruption to a busy office space.
Why Insulate Above A Suspended Ceiling
Many office buildings tend to have suspended ceilings below roof height so that light fittings and a general ambience can be achieved. Suspended ceilings are notoriously difficult to insulate due to the complexity of ceiling tiles dropped into a suspended metal frame. Where insulation is non-existent or sub-standard, there can be many issues such as excessive heat loss in the winter and solar gain during the summer all of which contribute to a difficult working environment. The solution is to insulate the roof which prevents solar gain at the source and adds a thermal layer to the envelope of the building to prevent a cold roof substrate condensation in winter months and dripping down onto the suspended ceiling. If the ceiling tiles have any signs of water damage, you can rest assured there’s either a roof leak or condensation dripping down from the roof. With access to the roof compromised by the complex array of ceiling tiles, any insulation solution will be tricky and time-consuming but Spray Foam Insulation will often be the most viable solution.
How Is Spray Foam Insulation Installed Above A Suspended Ceiling?
Firstly, the spray foam operative will still need to pop up through the ceiling tiles and will generally erect a scaffold tower or platform just below the ceiling so that they can stand safely. Once they are mobilised, there are no materials to carry up through, unlike pre-manufactured mineral wool. The spray foam insulation is manufactured in situ and just the hose and application gun will need to be mobilised through the ceiling frame. Using a canon tip, the spray foam insulation can be installed to the underside of the roof from up to 3 metres away and a fairly wide coverage of around 10m2 can be achieved just from popping up through a single ceiling tile. This reduces the risk of damage to the ceiling tiles, ensures the insulation programme is completed in a fraction of the time and leaves the building envelope protected from seasonal weather variances to leave an office workspace that’s cooler in the summer and warmer in the winter. All of this contributes towards a happier workforce and controlled expenditure on energy costs!

Gallery
Check out our Gallery where you will find some photographs of installations we’ve completed in the past. Whilst spray foam is insulation and not decoration, our experienced installation teams will always endeavour to provide a neat and tidy finish to the insulation. Nexseal LE closed cell is easier to achieve a neater finish whereas Sucraseal Open Cell expands at a faster rate to leave an undulated finish.
FAQs
Generally not. Our operatives are able to pop up through the suspended ceiling tiles and spray apply the insulation directly to the underside of the roof. Using a canon tip for the spray gun, our operative will be able to reach around 6m2 per ceiling tile which means far fewer tiles will need to be lifted therefore reducing the risk of damage. The process will be much faster than traditional types of insulation.
Pre-manufactured insulation materials such as mineral wool tend to shrink and degrade in performance over time. Spray Foam Insulation is a much more robust insulation system that isn’t impacted by natural degradation or a reduction in performance due to failing fixtures. Spray Foam is spay-applied directly to the substrate and has an exceptional bond strength which means it’s far less impacted by gravitational pull. It’s also faster to install and is less likely to be moved or damaged over time.
Yes, once fully cured, spray foam insulation emits no harmful gases and it uses the very latest water-based HFO blowing agents. In addition, our products are Class 1 fire-rated for surface spread of flame which generally exceeds the requirements for insulation materials in non-habitable spaces or voids.
Life! Spray Foam Insulation, if installed correctly, should last for the life of the surface onto which it’s installed. Therefore, unless you need to replace the roof, it will just sit there and perform without any degradation or diminishment as time goes by. This makes it an unbeatable solution when compared to pre-manufactured forms of insulation that are subjected to being fixed into place and then reliant on the quality of those fixtures. We guarantee spray foam insulation installations for 25 Years in terms of product performance.
Yes to a degree but we can also work weekends and overnight to minimise the impact. The big factor is to ensure that we adequately protect assets from the impact of the spray foam overspray, although with the suspended ceiling limiting the risks, there is much less that can go wrong. On a case-by-case basis, we will always endeavour to work flexibly around the needs of your business to ensure the insulation programme is completed quickly and efficiently with minimal fuss.
Spray foam offers exceptional thermal performance and is spray-applied to create a seamless, monolithic, and airtight thermal layer of insulation that stops heat loss at source. Unlike traditional insulation materials, spray foam adheres to the substrate and will not diminish or reduce in performance over time.
