Back Flashings (or Flat Back Soakers) are designed to provide a second line of defense behind a vertical control joint to prevent moisture from entering the cavity due to the shrinking of the cladding boards.
Redway uPVC Back Flashings are available in 3 sizes (40mm, 135mm, and 160mm) with all profiles supplied in 2.7m lengths.
Each Back Flashing should be installed vertically behind the cladding joint.
Internal flashings to deflect & drain moisture at key joints & penetrations.
While leaks primarily occur around windows and doors, they also occur at other joints and penetrations of the cladding and trim. The NZBC, therefore, requires flashings to be installed in order to ensure weather tightness and maintain the overall health of the building. Internal flashings provide a moisture barrier and drainage plane that prevent moisture build-up and deflect moisture to the building exterior. All Redway Internal flashings are manufactured from corrosion-resistant, UV-protected uPVC, and are available from all leading building merchants.
