01Start with your building

Pick the building, or the surface the foam goes onto.

Industrial units, warehousing, retail and public buildings, and the farm buildings around the city. Pick yours for the problem that building has, how the work is phased around its use, and what a specification has to establish first.

03Why Plymouth buildings need it

New industrial floorspace, a coastal city, and roofs that have to perform from day one.

Plymouth is adding industrial and warehouse space, much of it on Freeport sites. Units of this size are usually a profiled steel sheet over a lightly heated floor: the building that condenses most, and on the coast the one whose fixings salt air finds first. Read industrial units and factories and corrosion of metal roofs.

04How a job runs

Photographs or a survey, a specification, then the application.

The same three stages on every HOLVEM job, in Plymouth or anywhere else. You bring the building and what is bothering you about it; we bring the rest, in this order.

STAGE 01Show us the building

Send photographs and explain what you have noticed, or discuss a survey. The survey is free, with no obligation. Our survey or photographs guide helps you choose where to begin.

STAGE 02Establish the specification

We check moisture and calculate the U-value of the whole build-up before selecting the foam type and depth. Condensation risk analysis informs the recommendation. Tell us about the building's use and any thermal target in your brief.

STAGE 03Apply the specified build-up

Roof and soffit work is carried out from beneath, with access and sequencing considered for your site. At Derriford, the two layers were sprayed from scissor lifts in two stages.

05Straight answers

The questions Plymouth building owners ask first.

Answered the way the specialist answers them on the call. A question we have not covered? Ask it when we speak. No obligation.

Do you carry out commercial spray foam insulation in Plymouth?
Yes. Covered from HOLVEM's Exeter depot, one of four depots (Weybridge, Bedford, Manchester, Exeter) that give HOLVEM nationwide coverage. Tell us where your building is and what needs attention when you Start a project brief.
Have you worked on buildings in or near Plymouth?
Recent projects in Plymouth include The Box and Derriford District Centre. Their soffits required different build-ups: 120 mm of closed-cell foam at The Box, and 25 mm of closed-cell foam with 160 mm of open-cell foam at Derriford. We also installed closed-cell foam to 1155 m² of agricultural roof and walls in nearby Liskeard in September 2026. See The Box project for the access conditions and specification.
Can the work run around a working site in Plymouth?
The sequence needs to suit your site's operations. Closed-cell foam can be applied from below zone by zone. On the Nuneaton Signs project, 2924 m² was worked at weekends with production untouched. That is an example of a planned sequence, rather than a promise for every site. Include working hours, access restrictions and activities beneath the roof in your brief. Our industrial unit and factory insulation page explains this approach.
What should I check before commissioning insulation at Langage Energy Park?
Ask your landlord or Freeport contact how the Gateway Policy applies to your premises and whether the proposed work needs their agreement. Share any requirements with us before the specification is developed. The building still needs its own assessment, including moisture checks before depth is selected. Read how a job runs to see where that assessment fits.
How quickly will HOLVEM respond to an enquiry from Plymouth?
Enquiries received before 3pm on a working day are contacted the same day; after 3pm, the next working day. That is when we contact you. A quotation follows the information and assessment needed for your building. Start a project brief with what you already know.
What does commercial spray foam insulation cost?
Read what commercial spray foam costs per m² for the pricing guidance. For your building, Send photographs and describe the area and the result you need.
What warranty comes with the work?
25 year HOLVEM workmanship warranty, plus the manufacturer's 25 year product warranty issued directly to you. Discuss the proposed work and its specification when you Start a project brief.
