The batten is made of polypropylene and forms a total Moisture barrier between the external cladding and framing.
Regardless of moisture in the cladding the batten protects the structural integrity of the building 100%.
The open design of the batten allows for total ventilation through the batten itself when installed in any orientation.
This eliminates dead air in the tightest of spaces around door and window frames where moisture is most likely to
with changes in ambient temperatures and maintains a consistent dry environment in the wall cavity
promoting a healthy building.
Because of the open configuration of the batten water that does enter into the cavity freely drains through the batten
and out the bottom of the wall regardless of orientation.
No water can pond on top of the batten. The webbing or flutes in the batten restrict water droplets from ponding and tracking
across the batten. Water droplets will remain on the cladding side of the cavity keeping the timber frame dry.
Manufacturing material for the batten is virgin food grade polypropylene resulting in a user friendly material for the builder
and a healthier environment for the occupants of the building. It is also non reactive with all building materials including
aluminium and steel claddings and fastenings.
The batten acts as a thermal break between external cladding and framing. It Reduces thermal conductivity increasing the "R" value.
This greatly restricts heat transfer making a building more energy efficient in hot and cold climatic conditions.
"O" ring seal
The three layers of polypropylene material seal around nail and screw fastenings which hold the cladding to the framework
stopping the capillary action of water from behind the head of the nail or screw on the cladding from getting past the batten.
In damp or raining conditions Cavibat always passes the moisture test before closing in with the cladding saving time and money
High compressive strength maintaining its shape under high compressive load. Impact resistant when hammered or screwed.
Resists splitting and cracking when fastenings are driven through the batten. The stable properties of polypropylene
eliminate expansion and contraction with changes in moisture content due to seasonal cycles or humidity levels.
This eliminates popping of nail heads a common cause of leaks through cladding.
The battens are supplied cut to length (two per stud) and are extruded in a uniform thickness with no knots.
Battens don't warp when left in the weather and left over lengths can be used for the next job.
A 100m pack of battens weighs approximately 15 kgs and can be carried in one hand. The small pack size of 280x400x1200 mm
allows for easy transport and handling around the building site. Up on the scaffold random lengths can quickly and
easily be cut with a stanley knife and fastened with a brad nail gun.
The polypropylene battens are recyclable at the end of the life cycle of the building and can be ground up and reused.
The polypropylene is 100% virgin so can be categorised maximising the value for the recycled material. Polypropylene is category '#5'
The Cavibat range of Cavity Batten Systems have been appraised by BRANZ as suitable for all cladding materials and is appraised to be
installed vertically and horizontally. Cavibat-R has been appraised as a thermal break and insulator for steel frame buildings.
100 + years
The life expectancy of the batten as used in cavity construction is expected to be in excess of 100 years.
