Spray Foam For Anti-Condensation Insulation

Enverge Nexseal LE Closed Cell offers the perfect solution to reduce or eliminate the impact of surface condensation in a variety of circumstances. From metal shipping containers and warehouse roofs to cement fibre agricultural barns and industrial buildings, as little as 1 inch of Nexseal LE will provide an anti-condensation insulation solution to banish surface condensation problems to the past.

Nexseal LE Anti-Condensation Insulation Benefits

Anti-Condensation Insulation

Nexseal LE is manufactured using the latest chemistry advancement to achieve safe installation practices thanks to the low-exothermic reaction of the Closed Cell foam. Unlike some other brands of Closed Cell foam, Nexseal LE can be sprayed in thick, 100mm layers without shrinking, cracking, or delaminating from the substrate. With a British Class 1 fire-rating, Nexseal LE also reduces the spread of flame across the surface in the event of a fire to help make it one of the UK’s leading Closed Cell foams.

Anti-Condensation Insulation Solutions

Enverge Nexseal LE comes in a winter and summer-blend to ensure that anti-condensation treatments can be applied year-round. The strong adhesion of Nexseal LE removes the ability for heat to penetrate cold, external surfaces which will eliminate the environment under which surface condensation forms. Unlike pre-manufactured insulation materials, Nexseal LE bonds to the substrate and requires no mechanical fixings to keep it in place. It is also installed up to 10 times faster than pre-manufactured insulation materials which leads to less downtime for busy buildings and a long-term thermal durability that lasts the life of the substrate. Anti-condensation treatments require as little as 1 inch (25mm).

FAQs

Why spray foam for corrugated surfaces?

Pre-manufactured insulation materials need fixing into place and generally won’t follow the undulation of the corrugate. This can leave cold pockets behind the insulation and unless the materials used are airtight, warm air from inside the building could still escape through the insulation and cause condensation pockets. The closed cell spray foam will bond to the corrugated surface and provide a seamless layer of thermal performance that will completely eliminate surface condensation.

Will my building need to be empty?

Yes, ideally. Firstly, we need as much floor space as possible to navigate a scaffold tower or cherry picker and secondly, there is often overspray particles that will fall from the roof during the spraying process and these particles can stick to machinery, stock and belongings inside. Whilst we will make every effort to cover items with protective sheeting, we cannot guarantee we won’t get overspray on items, therefore, where possible, its just best to empty the building. Due to health and safety regulations, we definitely can’t have the general public or employees in the building at the time unless they are in another zone.

Is spray foam fast to install?

Yes, typically it’s 4-5 times quicker than fitting pre-manufactured materials which can have a massive impact on how quickly you can use the building again. For businesses who rely on the space they are insulating, we can typically complete around 200-250m2 per day and for larger projects we can increase the number of installers on site to speed up the process. For most projects, we are generally in and out within a few days, leaving you fully insulated and your surface condensation issues resolved.

Which type of spray foam is best?

Our ThermoFoam Nexseal Closed Cell has been tested extensively with the BBA to ensure its suitability for bond strength, water vapour permeability and thermal conductivity. We’d always recommend using closed cell insulation to cement fibre, asbestos and metal surfaces due to its cohesive strength. Whilst some of our competitors may promote the use of open cell foam in these scenarios, it essentially has the density of a sponge, offers no structural stability and has a generally poor cohesion which could fail over time. Although we have our own ThermoFoam Sucraseal Open Cell Foam, we wouldn’t recommend its use direct to a corrugated surface

Will the spray foam stop leaks?

We don’t guarantee it against leaks. The negative pressure of the water from above will always find a way to penetrate through the smallest of crevices. The closed cell spray foam will, however, bond the roof sheets and any fixings which means if they are all in place before we spray, the foam will help to retain that structural stability. In high winds or stormy weather, the roof sheets are less susceptible to be damaged by wind and this should provide less tension on the fixings which means the roof will last for much longer as a result.

What Fire Rating Is Spray Foam?

Our Nexseal LE achieves a British Class 1 surface spread of flame which is generally accepted by property insurers. The fire risk of spray foam insulation is very low provided there are no ignition sources within 500mm.
