Flat Cladding Cavity Closers:

A top and bottom Cavity Closer is designed from extruded uPVC for either a Drained Cavity wall or Ventilated Cavity wall situation. 

• Adrained cavity wall is vented at the bottom only. Water can drain, and limited (but often sufficient) air can enter the cavity to dry any remaining moisture between wetting cycles.

Products required: Redway Cavity Closer. 

• A ventilated cavity wall is vented at the top and bottom. As per the drained cavity, the bottom vent allows drainage and air entry. The addition of the top vent creates a moving air path. This method should be considered when drying is inhibited due to rapid wetting cycles or where walls are permanently shaded, as they pose a higher risk of moisture build up and mould formation.

Products required: Redway Cavity Closer and Redway Top Vent Cavity Closer.
