Description
Preformed damp proof course barrier built into the inner leaf only of a cavity wall.
Features and Benefits:
- Available in all dimensions.
- Chlorofluorocarbon (CFC) free and zero ozone depletion potential (ODP).
- DPC control independent of external masonry skin.
- Uninterrupted structural bonding of outer skin.
- Protects a high level masonry feature that impinges a cavity without weakening or affecting the structural bonding of that feature.
- Prevents the top surface of a conventional cavity barrier acting as a bridge for penetrating water.
- Protects a conventionally shaped acoustic or fire cavity barrier from acting as a cavity-crossing bridge for penetrating water.
- Prevents damp penetration via a masonry feature within an external skin, without envelopment within that skin.
