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

Maylands' logistics setting makes storage and distribution buildings a useful starting point. The nearby proof also covers a performing-arts venue and an agricultural building, each with its own construction and use.

03Why Hemel Hempstead buildings need it

Maylands and the direction of refurbishment

For an existing building, translate the refurbishment objective into the area you want assessed: the roof above storage, a working unit or a soffit serving another part of the premises. Read warehouse and distribution roof insulation.

  1. S1

    Hemel Hempstead’s commercial premises include logistics buildings and working units considered for refurbishment. Roof or soffit insulation needs to address the part of the premises involved in that improvement. Dacorum Borough Council describes Maylands Business Park as Hertfordshire's largest employment area, with over 650 businesses and about 20,000 employees.

05Straight answers

The questions Hemel Hempstead 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 cover commercial buildings in Hemel Hempstead?
Hemel Hempstead work is covered from our Weybridge depot. Describe the premises and whether the enquiry is part of a refurbishment or a focused insulation upgrade. Start a project brief.
What nearby projects demonstrate your work?
The Alban Arena project used open-cell and closed-cell roof insulation around a venue programme. Pondswick treated 127 m² of exposed concrete soffit beneath switchgear rooms. View the Pondswick substation project for the latter scope.
Can insulation fit within a wider Hemel Hempstead refurbishment?
Supply the proposed programme and explain which areas remain occupied while work proceeds. The Alban Arena example shows work arranged around a venue programme; your refurbishment needs its own access and sequence agreed. Read the Alban Arena project.
How should an energy target inform my Hemel Hempstead enquiry?
Give the target and identify the construction it applies to, rather than requesting a foam depth alone. The proposed build-up can then be assessed against the intended use and moisture conditions. Add the project requirements to Start a project brief.
How quickly will you contact me about Hemel Hempstead premises?
Enquiries received before 3pm on a working day are contacted the same day; after 3pm, the next working day. Include any refurbishment target and programme when you Send photographs.
Where should I start with costs for a building upgrade?
The commercial spray foam cost guide provides the published guidance. For the quotation, supply the treatment area, construction, access and any performance requirement agreed for the wider refurbishment.
What warranty information can my refurbishment team request?
25 year HOLVEM workmanship warranty, plus the manufacturer’s 25 year product warranty issued directly to you. Set out the documentation needed by the owner and project team when the treatment scope is being established. We can discuss the relevant cover alongside the specification before you agree the work.
