Construction Insulation
Bespoke, high-performance foam insulation engineered for durability, precision and protection
For over 50 years, Kewell Converters has been a trusted partner for the construction industry working in sectors where failure isn’t an option. From military-grade infrastructure to aerospace manufacturing facilities, our bespoke foam solutions offer the insulation, sealing, and protection your critical projects demand.
Whether you’re sourcing components for high-spec, high-risk construction environments or managing complex supply chains, our in-house engineering team collaborates with you from concept to production—so you get more than just a foam part. You get performance. You get certainty. You get a solution engineered to last.
Foam conversion expertise for high-performance construction applications
As one of the UK’s longest-established foam converter focused exclusively on foam, Kewell Converters is uniquely positioned to deliver end-to-end foam fabrication and custom foam solutions that meet your project’s exact requirements.
We specialise in closed-cell, high-quality, branded foams—such as Zotefoams’ AZOTE® and ZOTEK® ranges—which deliver exceptional thermal, acoustic, and sealing performance while remaining lightweight and easy to fabricate into complex geometries.
Construction-grade foam solutions that solve problems
Our bespoke foam insulation solutions are engineered for industries that need more than just basic protection.
We work in partnership with procurement, production and quality teams to ensure materials meet exacting compliance and testing standards—and with engineers to optimise the design, performance, and manufacturability of every part.
Industries we cater for
Military & defence infrastructure
Flame-resistant, impact-dampening, and thermally stable foam parts for mobile command units, shelter structures, and vehicle interiors
Aerospace construction & fit-outs
Lightweight, high-performance foam inserts, panels, and gaskets that meet stringent flammability and durability standards
Industrial installations
Sealing and insulation solutions for HVAC systems, ductwork, plant enclosures and noise reduction enclosures
Construction & civil engineering
Precision-cut foam for protection, joint sealing, pipe insulation, thermal barriers, and acoustic insulation in both temporary and permanent structures.
A smarter approach to foam in construction
At Kewell Converters, we go beyond material supply. We help simplify your procurement and production process. Need to integrate foam into a larger part or assembly? We’ll take care of the design, fabrication, and even supplier liaison—so you don’t have to manage multiple vendors or risk misaligned components.
With our collaborative, consultative approach, you’re not just buying foam—you’re buying into over 50 years of specialised experience in foam conversion and bespoke foam solutions.
