High Temperature Thermal Insulation Jackets
Some applications simply push standard insulation beyond its limits. Steam distribution mains, boiler plant, turbine casings, heat exchangers running at sustained high temperatures: these need specialist materials and a design built around the actual conditions on site.
Lagflex manufactures high temperature removable insulation jackets for exactly these applications. Every jacket is designed and built in-house, using materials selected specifically for their thermal resistance, durability and long-term performance under continuous high-heat conditions. Contact us to discuss your application, and we will recommend the right specification.
When do you need high temperature insulation jackets?
If your application falls within the temperature range of standard HVAC or heating systems, our standard thermal insulation covers will almost certainly be the right starting point. High temperature jackets are the answer when operating temperatures exceed what standard mineral wool systems can reliably handle.
They are also the right choice wherever permanent insulation is impractical because of frequent maintenance access. High temperature lag jackets give you the same thermal performance as hard insulation, but they come off in seconds and go back on just as quickly. For steam trap testing, valve maintenance and instrumentation checks, that matters enormously.
