Nexseal Closed Cell Spray Foam
Nexseal For Homeowners
Nexseal Closed Cell Foam can be used in retrofit environments for pitched roofs, suspended floors and wall insulation. Due to the vapour closed yet breathable structure of closed cell, a hygrothermal analysis should always be conducted to determine the suitability of Nexseal in a particular environment. It can also be spray-applied to a rafter slide to create a retrospective protective layer where a roof membrane has perished or isn’t present. We do not allow ThermoFoam-approved contractors to apply Nexseal direct to roof tiles as a stabilisation mechanism.
Nexseal For Industrial & Agricultural
Nexseal is used in a variety of circumstances including corrugated roofs, concrete soffits, shipping containers, pipelines, silos to name just a few. The versatility of spray-applied Nexseal closed cell foams make them the perfect solution for a wide variety of insulation and anti-condensation requirements. The strong adhesion of Nexseal helps to create a seamless, monolithic layer of insulation that cannot be matched with pre-manufactured forms of insulation. The fast application of Nexseal helps to minimise down time, returning the building back to service rapidly.
Nexseal For Spray Foam Applicators
The Nexseal product range has suitable foams that achieve different results depending on requirements. Our V1 high lift foam can be applied in 100mm passes whilst V3 is a winter-blend that can be used in cold weather. V4 and V5 focuses on enhanced fire performance in commercial environments, boasting a Class 1 and Class 0 surface spread of flame rating by utilising a spray-applied intumescent coating. Spray Foam Applicators choose Nexseal because it’s a low fuss, easy to use and reliable range of closed cell. Nexseal can achieve a British Class 1 and 0 fire rating when a spray-applied coating is added.
Nexseal For Architects & Specifiers
Extensively tested by the BBA under UKAS testing standards, Nexseal V1-V3 has achieved completion of the technical assessment which will lead to BBA certification for it’s HFO and winter-blend formulations. As a part of the process, a separate LABC certificate is due to be issued in due course, rendering Nexseal as the best choice for any new build or commercial project where certification will be required. If you are an architect or specifier, we can work with you to help provide a strong understanding about the capabilities of spray foam, enabling you to confidently specify and use it on your projects.

Case Studies
Sloane Gardens, London
This boutique hotel has been redeveloped recently by Delmond Construction. With the thermal upgrade representing part of the scope of works, ThermoFoam were appointed to insulate the old stone walls. With the basement area being used as a bar and snug, the client opted for the rustic appearance of the foam to be left exposed and not covered by plasterboard. This required a spray foam technician who was able to get as neat a finish as possible with what is essentially a high pressure expanding foam. Coated with DC315 to provide a thermal spread of flame barrier, the end results of this install impressed the client and has led to a multitude of further work.
St Boniface’s Veterinary Clinic
We love an interesting project here at ThermoFoam and the requirements for St Boniface’s were certainly interesting! The plan was to use a 20 foot shipping container as an inspection vessel for livestock. We insulated the walls, ceiling and doors at 50mm using Nexseal in order to eliminate condensation and provide some good thermal performance. The livestock would be drafted into the container, inspected, treatments carried out and then released through the rear doors. If the pro-type container goes to plan, it is likely that ThermoFoam would be required for a larger scale roll-out. Who would’ve thought shipping containers could be so versatile!
