As our building standards continually evolve, timber joinery was, for a period, left behind. “As a result, the timber joinery industry banded together, and over the last few years we have been collectively working with the Ministry of Building, Innovation and Employment to bring it up to the latest legislative standards,” Dando Timber Doors and Windows’ Aaron Dando says.

“As an industry, we’ve all chipped in and tested products and methodologies and we’ve achieved something really impressive. It’s something that as an industry we are really proud of and we’re now in a situation where timber joinery meets the highest standards of the current Building Code.”

Under the Building Code, NZS 4211 is the standard for the performance testing of individual windows and doors. They are tested, including the glazing system, and are then certified as complying with one or more New Zealand wind zones. “The NZS 4211 Compliant Timber Joinery programme was developed by a group of New Zealand Master Joiners who manufacture timber doors and windows, of which we are one. We can now label our products to certify that they comply with the requirements of NZS 4211 for the wind zone within which the products will be installed.”

Members of the programme also now work with territorial authorities, specifiers and tradespeople by providing drawings, specifications and installation instructions for timber joinery to ensure it retains a superior standard.

This new generation of timber joinery far exceeds the performance of the oft-favoured aluminium alternative.

timber window frames is significantly less than for a standard aluminium frame,” Aaron says.

“It helps to keep homes cold in summer and warm in winter, reducing heating and cooling costs.”
Glazing is often considered vital in the management of heat loss through windows and doors, but extensive testing has shown that it is not just the glass that makes the difference; it is the combination of glass and framing.

The thermal performance of a building element is usually defined by its thermal resistance (R value), with the larger the R value, the harder it is for heat to escape through the wall. The walls of a zero energy house have an R value of R3, but windows in a zero energy house will differ. “For example, double glazed low E glass combined with aluminium joinery has an R value of R0.31 but the same glazing combined with timber joinery has an R value of R0.48,” Aaron says.

“Timber is now one of the best options for insulation properties. But it has a flair and functionality too. Timber joinery exudes a natural elegance. It’s part of the traditional Kiwi vernacular, and in new homes offers a distinctly high-end feel.”
Dando has been operating for almost three decades, manufacturing all its joinery at its central Auckland premises.
