About Foam PVC

Foam PVC combines low density with high rigidity and good sound and heat insulation.

It offers several distinct advantages over solid PVC sheets – including being approximately half the weight, a more effective thermal insulator, easier to handle, vibration and oscillation absorbent, and more cost-effective per unit area.

It is used for advertising signs and displays, in construction, and for many miscellaneous applications such as transport containers and model making.

1835 – PVC is discovered by accident by Henri Victor Regnault after exposing vinyl chloride to sunlight. It would be re-discovered in 1872 by Eugen Baumann

1930s – The first PVC foam material designed for a marine environment, consisting of a PVC and isocyanate blend, is created in Germany. It is rumoured that it was used in German E-boats and the Bismarck battleship


Foam PVC offers excellent processing qualities in addition to light weight, high rigidity, moisture resistance, and low flammability. It is used for the following:

  • Advertising: Foam PVC is used by advertisers for signs, displays and exhibition stands, and as photograph backing
  • Insulation material: Foam PVC provides excellent heat and sound insulation and is used as sub-frame material in double-glazed windows
  • Construction: Partitions, wall cladding, facades, interior decoration and air-conditioning ducts are constructed from foam PVC, which can be painted, printed, engraved or milled to specification
  • Shop fitting: Shop counter designs incorporate foam PVC, which is also used to make decorative wall panels

Foam PVC is also used for transport containers and in model-making, where it is popular for being easy to cut, shape and paint.
