Commercial Spray Foam Insulation in Scarborough

Spray foam on Scarborough commercial buildings

No two commercial roofs are the same, and the right answer is not always spray foam. Most enquiries in Yorkshire & the North East come down to heat loss and condensation over big open spans, and the survey exists to establish what is actually causing it before anything is specified.

What we check before quoting

We start with what the roof is made of and what condition it is in — corrugated fibre-cement, profiled steel, concrete or timber each need their own preparation. Existing leaks are identified first, because spraying the underside of a roof does not make it watertight; rainwater ingress, condensation and structural defects have to be told apart before a treatment is chosen. Internal humidity and building use are recorded too, since they drive condensation as much as the roof does. On asbestos-cement sheeting, encapsulation may be an option — the material remains in place and still needs managing.

The system we specify

Closed-cell Nexseal LE covers most commercial buildings we insulate in Yorkshire & the North East. Sprayed in place it self-bonds to the substrate and keeps the inner surface above dew point, which is what ends the drip and the corrosion that follows it; it also carries a 25-year manufacturer-backed product warranty. Where a building needs vapour to move more freely, open-cell Sucraseal is the specified alternative. The system and the thickness are both fixed in writing before work starts — see the guide to stopping condensation for how the two decisions interact.

How the installation runs

Installations are programmed around how the building is used, so trading or production continues wherever it can. Protection goes up first, rooflights and services are masked, then the foam is applied in passes and checked against the specified thickness before anything is taken down. A typical Scarborough building is a matter of days on site. Specification, product data and warranty documentation are handed over at completion.

What a job costs turns on area, specified thickness and access, which is why a figure before a survey is guesswork; the cost guide sets out the variables honestly. Send us the postcode, the roof type and rough dimensions to arrange a free survey in Scarborough.
