Pipe Lagging & Jackets

Pipe lagging and jackets provide essential thermal protection for your plumbing system, preventing heat loss from hot water pipes and guarding against frost damage during cold snaps. Properly insulated pipework maintains water temperature more efficiently, reducing energy consumption and cutting heating costs throughout the year. From domestic heating systems to hot water cylinders, quality pipe insulation is a straightforward upgrade that delivers lasting performance benefits.

Our Pipe Insulation Range

McMahons stocks a practical selection of pipe and cylinder insulation products from trusted brands including K-Flex and BSS.

  • K-Flex self-seal foam tube insulation - pre-slit foam sections in a range of pipe diameters (15mm, 22mm, 28mm and more) with a self-adhesive closure strip for fast, tool-free installation around existing pipework without disconnection.
  • BSS cylinder jackets - purpose-made hot water cylinder covers for standard copper cylinders (36x18 inch and 42x18 inch), significantly reducing standby heat loss from uninsulated tanks.
  • Multiple pipe sizes - insulation sections sized to suit standard domestic copper pipework, ensuring a snug fit for effective thermal performance across heating and hot water systems.

For a complete thermal envelope throughout your building project, browse our full range of Insulation Materials covering walls, floors, and roofing applications.

Selecting the correct insulation thickness depends on pipe diameter, operating temperature, and location. Pipes running through unheated spaces like garages or lofts require thicker coverage to prevent freezing and minimise heat loss. Always ensure the foam internal diameter matches your pipe size for a proper snug fit and maximum thermal performance.
