While minimising any impact on the environment, Dynex is committed to providing innovative solutions for New Zealand buildings, with a focus on design, durability and aesthetics.

The latest Dynex Optivent cavity closer range is no exception. Dynex is delivering the next step in the evolution of cavity closers, offering a smart solution to the issue of unsightly slots without compromising on performance or affordability.

Made from UV and impact-resistant material, this enhanced design is BRANZ appraised. Dynex has taken innovation to the next level with these universal cavity closers which have been designed with discreet ventilation and unique horizontal nailing grooves for easier installation. Optivent cavity closers have vertical slots providing twice the ventilation requirement of the New Zealand Building Code.

With improved drainage, the sleek new design conceals the ventilation slots, ideal for second-storey overhang applications. The placement of slots in this improved design also means the soffit can be brought right under the cavity closer, all the way up to within  5mm or 6mm of the cladding itself, to further improve the look. Building with Optivent is simple. Supplied in 3m lengths, it is available in 18-25mm, 30-35mm and 45mm sizes, to suit different applications.

Optivent is available in two colours —white or graphite — giving the designer the flexibility to match the cladding or soffit and
achieve the ultimate finish. It is suitable for use with all relevant cladding types as per the current Dynex cavity closer range.

Remember Optivent and the 5 Ds:

• Deflection — working with the cladding to deflect moisture.
• Drainage — allowing water to drain.
• Drying — increased ventilation, ensuring a dry cavity.
• Durability — long-lasting uPVC, made for New Zealand conditions.
• Design — optimum efficiency with concealed ventilation slots.
