Dryvit Low Lambda (LL) expanded polystyrene (EPS) is manufactured to the requirements of BS EN 13163 from pre-foamed beads of polystyrene. These are fused together under pressure in a steam-heated mould to produce a lightweight cellular plastic with an enhanced thermal insulating performance to that of standard EPS (white).

It is available as a Dryvit Square Edge board for use in Dryvit Outsulation and Drysulation direct fix External Wall Insulation (EWI) Systems, the Fedderlite Panel System or as Dryvit Grooved EPS board for use with the Outsulation Rail System.
