The strong sisal vapour barrier coupled with the closed cell low density inorganic polyurethane makes Permablock ideal for high humidity environments, as it won't absorb moisture and will never rot.

Low thermal conductivity minimises the potential for heat gain or loss, ensuring maximum efficiency,

With a simple one step installation process eliminating the need for cutting and taping, Permablock is quick, easy and safe to use.

The low density inorganic Permablock suits all standard tube and pipe sizes and wall thicknesses but our high density Permablock is recommended for use on pipe sizes greater than 100mm nominal bore. Custom sizes are also available to order.

Choose Permablock for optimum performance even in the most demanding applications.
