Features and Benefits

• Prevents cold bridging
• Insulated with polyethylene foam
• Conforms to BRE guildelines for thermal insulation


Mayplas insulated DPCs consist of an insulation bonded to a strip of a polymeric DPC. The DPC strip overlaps the insulation at both edges to allow for the extension of the DPC into the window or door and cavity.

Its thermal properties are derived from polyethylene foam and the DPC prevents the ingress of moisture.
