Rain Screen Components


VaproBatten is a UV stable, breathable vinyl batten system for rain screen applications. Its unique and innovative design is a direct replacement for pressure treated plywood furring or treated lumber battens.

Drying Capacity

Unique formed air cavity allows unobstructed air flow, increasing drying speed in the drainage plane reducing moisture damage caused by mold, mildew, rot and corrosion.

Durability and Cost Effectiveness

  • Ships in 5' lengths for easy ground shipping and installation.
  • Will not rot, eliminating repair costs and preventing moisture related damage within the drainage plane.
  • Eliminates the need for stainless steel fasteners.
  • Bull-nose edges prevent membrane tearing or ripping upon application.
  • Fasteners are installed directly through VaproBatten into the structural elements regardless of weather conditions.

Environmental Sustainability

  • Is 100% recyclable supporting green building design.

Batten Accessories: VaproVent Strips


VaproVent Strips are available in two types:

  • VaproVent L Strip
  • VaproVent Hook Strip 


VaproVent LStrip 021116cropsmall VaproVent HookStrip

VaproVent L Strips are attached to the top and bottom of VaproBattens.They prevent insect invasion and provide maximum ventilation.

VaproVent Hook Strips are used with VaproBattens as a starter strip for vinyl and beveled siding applications, in place of the VaproVent L Strip at the bottom of the assembly.

  • Creates unimpeded drainage plane in vertical and horizontal applications
  • Seals fastener penetrations/air and water tested ASTM E-331
  • Increased drying capacity
  • Zero VOCs
  • All weather application
  • Adds minimal thickness to wall assembly
  • No compatibility restrictions
  • Adds thermal break
  • UV resistant (open joint cladding option)




VaproShim SA™ Self-Adhered Neoprene/EPDM accessory used under horizontal or vertical cladding attachment components creates the desired vertical rain screen drainage plane for cladding, while sealing fastener penetrations. This simple design adds minimal cost while adding substantial drying capacity to the building envelope.

Lightweight, hydrophobic polyester filter fabric with an attached polyproplene drainage matrix. Installed over VaproShield WRB/Air Barriers, it creates a positive drainage cavity behind cladding, promoting rapid drying of the building envelope.

  • Two depths: 3mm or 7mm
  • Ideal for use with stucco or cultured stone
  • Filter backing keeps drainage cavity clean during lath and plaster
  • Easily works with traditional cladding systems such as metal panels, composite panels, and wood siding
  • Increases building envelope drying capacity
  • 3mm recommended for use in arid climates requiring minimum drainage and where cavity depth is restricted due to design constraints
  • 7mm recommended for mixed climates and high humidity to maximize drainage and drying from liquid water and reverse vapor drive
