The function of the Weatherboard Starter / Cavity Closer is to provide support and the correct starter angle for the first course of weatherboard, prevent vermin intrusion, and to promote weather-tightness by allowing drainage and air ventilation to dry the cavity should moisture breach the external cladding. The Redway range of uPVC Weatherboard Starters have been designed to provide the ideal solution for architects, builders and installers to meet these requirements. Redway Weatherboard Starters / Cavity Closers are available at all leading building merchants nationwide.

Redway has designed a top and bottom Cavity Closer from extruded uPVC to be used in either a Drained Cavity wall or Ventilated Cavity wall situation.
- A drained cavity wall is vented at the bottom only. Water is able to drain and limited (but often sufficient) air is able to enter the cavity to dry remaining moisture between wetting cycles.
Products required: Redway Weatherboard Starter/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. 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. An example detail of the ventilated cavity is illustrated on the right.
Products required: Redway Weatherboard Starter/Cavity Closer and Redway Top Vent Closer
- Extruded uPVC strip.
- Fits weatherboard or flat panel up to 20mm thick.
- Front ventilation holes that promote air flow and allow air and moisture to exit the cavity.
- Raised back edge to prevent wind-blown rain or hose water from saturating the cavity.
- A positive slope to direct any water towards the building exterior.
- Flat top edge to butt against the soffit for a tight seal.
- Creates an air path from the bottom cavity closer that will increase the rate of drying.
- Allows air and moisture to escape reducing the risk of deterioration.
- Easy to install.
- uPVC material is biologically and chemically resistant to treated materials, nor will it rust or react if in a salt zone.
- Cut to the exact size on the building site.
- Lightweight for easy transportation and installation.
