Nu-Wall Offers Cladding with a Long-Term View

Nu-Wall Aluminium Cladding is increasingly being specified on the many new housing developments around New Zealand, in both the private and public sectors. The high durability of the product, coupled with a low requirement for maintenance, results in a significantly lower cost of ownership over the life of the building. This is of particular importance to owners who plan to hold the property over a long term.

Additionally, the wide range of cladding profiles and finishes offered, plus the choice of either horizontal or vertical cladding profiles, provides specifiers and their clients with the opportunity to create individual aesthetics within a housing development without deviating from the scope of the overall project Building Consent.

The above images illustrate some examples of completed housing projects, with cladding profiles having been specified to suit the house designs. Shown are an example using a horizontal weatherboard-type profile, and two others on which flat 200mm-wide cladding profiles were installed vertically.
