Long Panel

Long Panel manufactures a variety of insulation panels to a range of specifications. The primary panel core material is EPS (Expanded Polystyrene Sheet), while other core materials, such as PIR (Polyisocyanurate), are also used when specified to meet Customers’ requirements.

In addition, we produce an extensive range of specialist polystyrene packaging, insulation and architectural products.

First established in 1993, the Long Panel group now operates as two separate but fully integrated entities:
