Commercial Spray Foam Insulation in Malvern

What a Malvern spray foam installation involves

Across the South West we are usually called about heat loss and condensation across very large industrial roofs. The building tells us what it needs — the survey establishes whether insulation is the right answer, and if so, which system and what thickness.

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 the South West. 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

Work is phased around your operation. Areas are sheeted and protected, services and rooflights masked, and the foam applied in controlled passes to the specified thickness, with coverage checked before the protection comes down. Most buildings in Malvern are sprayed in days rather than weeks and stay in use for much of it. You receive the specification, the product documentation and the warranty paperwork at handover.

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 Malvern.
