DPC foil, or Damp Proof Course, is an essential water-repellent foil that is widely used in the construction sector. It plays a crucial role in preventing problems caused by rising or penetrating damp in wall constructions. This film is usually made of black LDPE (Low Density Polyethylene) and is characterized by a waffle structure, which not only ensures excellent adhesion on mortar, but also maintains a certain distance to the surface. This can help reduce cold and condensation.
