Jacketing in PVC Isolpak®



ISOLPAK® is a special rigid PVC jacketing film for insulated piping. This plastic sheet ensures a clean and dry installation. Its application is easy and fast due to the curl (recoil) effect.

ISOLPAK® is self-extinguishing and has considerable resistance to acids, alkalis, salts, oil, petrol, aliphatic hydrocarbons and corrosive atmospheres.

In addition, the material cannot corrode and is virtually impermeable to water vapour. It is unaffected by fresh and salt water and is impervious to gases, grease and oil.


The chemical characteristics of ISOLPAK® are matched by equally good physical characteristics: high longitudinal and lateral tear resistance, high elasticity and shock resistance.

ISOLPAK® is very light: one square metre, 0.350 mm thick, weighs only about 500 g. This low weight and ease of stacking facilitates transportation and storage.
Physiologically harmless, ISOLPAK® has a light grey smooth surface which guarantees a long lasting elegant appearance. It requires no care or maintenance and also has very good antistatic characteristics.
The material has considerable resistance to temperature changes and is stable from -20°C up to +65°C in indoor use.
The thermal conductivity, of ISOLPAK® is 0.16 W/mK.
