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

Food manufacturing, logistics, film and prop houses, and vehicle repair all feature in Park Royal’s industrial mix. What happens inside your premises matters to the recommendation.

03Why London buildings need it

Space for work, stock and the installation itself

London’s industrial land is tightly packed, with food production, logistics and studios working beneath the roofs. Access to the roof and the working space beneath it need considering together. Read warehouse and distribution roof insulation.

    Park Royal is London’s largest area of Strategic Industrial Land. The Greater London Authority describes around 1,700 businesses employing 43,100 people, across food manufacturing, logistics, film and prop houses, and vehicle repair.

  2. S2

    GLP describes the industrial park as occupying about 500 hectares, with access to the A40 and A406.

04How a job runs

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

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

STAGE 01Share the views

Show the roof or soffit, the occupied space below it and the access available. Note any site rules or vehicle requirements.

STAGE 02Specify for the construction

The building assessment and moisture checks establish the proposed build-up. Where a thermal target is set, the U-value is calculated for the whole construction.

STAGE 03Arrange the application

The work needs a prepared surface and an agreed sequence. Discuss the activities beneath it while that sequence is being planned.

05Straight answers

The questions London 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 London?
London projects are covered from HOLVEM’s Weybridge depot. Describe the roof or soffit and the use of the building, including any restrictions on access. Use Start a project brief to put those details together.
What recent insulation work have you completed in London?
Recent London installations include 324 m² of metal mezzanine deck underside in September 2026, an industrial unit in July 2026 and 255 m² of single skin metal roof and walls in April 2026. All used closed-cell foam. For the method behind underside work, read the commercial spray foam insulation service.
Can you take account of trading or working hours in London?
Tell us when the work area can be accessed and what must remain available around it. The Alban Arena record shows work planned around a venue programme; the arrangement for your premises needs considering separately. Read the occupied venue project, then include your operating requirements in the brief.
What should a Park Royal site tell you about contractor access?
Include vehicle restrictions, delivery arrangements and any limits on loading or equipment space. Park Royal’s position inside the ULEZ makes vehicle planning a useful point to raise with the site manager. Those access details sit alongside the building assessment, not in place of it. See how a job is planned.
When can I expect contact about a London building?
Enquiries received before 3pm on a working day are contacted the same day; after 3pm, the next working day. That timing applies to contact. Please Send photographs and any access notes so the conversation can begin with the building’s actual conditions.
What affects the cost of spray foam in London?
The specified depth, surface preparation, coatings and access affect the work. A local installation area is evidence of a project, not a price for the next one. The spray foam insulation cost guide explains the rates and what needs establishing for a firm quotation.
What warranties accompany a London installation?
25 year HOLVEM workmanship warranty, plus the manufacturer's 25 year product warranty issued directly to you. Share any requirements from your facilities or estates team through Start a project brief before the scope is agreed.
