About Lagflex

UK Manufacturer of Removable Thermal Insulation Jackets

Lagflex is a specialist UK manufacturer of removable thermal insulation jackets, based in Oldham. We design, manufacture and supply precision insulation jackets for valves, pipes, flanges, HVAC systems and industrial plants across the United Kingdom.

Everything we make is produced in-house at our Greater Manchester facility. We do not outsource our manufacturing. Every jacket that leaves our site has been built to our standards, inspected by our team, and engineered for the application it is going into.

Our story

Lagflex was founded with a straightforward purpose: to give UK businesses access to genuinely high-quality removable insulation solutions, manufactured on home soil. Over decades in the industry, we have built a reputation for precision engineering, reliable lead times and technical support that actually helps.

We have supplied insulation jackets to businesses across HVAC, steam, oil and gas, food and beverage, pharmaceutical, marine and general industrial sectors. A single valve cover for a plant room in Manchester, a full site installation, or bespoke jacket sizing, every order gets the same rigour from our team.

What makes Lagflex different

There are insulation jacket suppliers in the UK. What sets Lagflex apart is that we are a manufacturer, not a middleman. That distinction matters when you are specifying a product for a critical application.

Tighter tolerances

We manufacture to your exact dimensions. Standard sizes that have to be forced to fit are not good enough for precision pipework

Faster turnaround

No overseas supply chains and no third-party lead times. Your order is built here and shipped directly from Oldham

Real technical expertise

Our team understands the application, not just the product. Material selection, insulation thickness, fastening systems: we can advise on all of it

Flexibility on quantity

One-off bespoke covers for unusual fittings through to bulk orders for full site installations

UK quality throughout

All materials are tested and selected for performance in demanding industrial environments
