Home›Spray Foam Insulation›Approved Installers
Vetted, trained contractors installing Nexseal LE closed-cell spray foam insulation. One company, one warranty, one point of contact — from enquiry to completion.
Duratite Projects Limited operates a managed installer network across the UK. Unlike hiring an independent spray foam contractor, our model gives you one company responsible for everything — the product, the installation, and the warranty.
Every approved installer is personally vetted by Duratite, trained on our product systems, and works exclusively with Duratite-supplied materials. They do not source their own foam. This guarantees consistency, traceability, and accountability on every project.
Duratite approved installers cover all major regions of the United Kingdom. Tell us your postcode and we will assign the nearest team.

Call us on 01208 832 602 or submit an online enquiry. Tell us your building type, location, and what you need insulated.
We arrange a free site survey to assess the building, measure areas, check access, and identify any preparation needed.
You receive a detailed, fixed-price quotation covering product, installation, and warranty. No hidden costs, no surprises.
Your nearest approved installer carries out the work using Duratite-supplied Nexseal LE. Full documentation and warranty on completion.
Here is what the approved-installer model means for your project.
Every installer is trained specifically on Nexseal LE application techniques, thickness requirements, and quality standards before they are approved.
All approved installers carry public liability insurance and professional indemnity cover. Your property and project are protected at all times.
Installations include a workmanship warranty from the installer and a product guarantee on Nexseal LE, all managed through Duratite.
The closed-cell foam we supply is covered by BBA Agrément Certificate 23/6963, held by our group company ThermoHoldings Ltd, covering pitched roofs, external walls and suspended floors in domestic buildings. Every installation uses the same Duratite-supplied material.
You deal with Duratite from first call to final handover. One company, one invoice, one warranty. No chasing subcontractors.
Every project includes thickness verification reports, site photographs, product batch traceability, and warranty certificates.
