thermawood range completes as 2047 testing
01 02 adapter and the 26 mm silicon glazing block being the only difference.
Fabrication
The Thermawood system is designed to be easily installed into current fabrication processes- the depth of the rebate and the shaped bottom rail are the only variances in machining sashes or doors.
Thermawood recently undertook and passed testing for NZS 4211:2008 and AS 2047 Extra High Wind Zone for a 26 mm thick IGU. The window tested was a 2140 mm x 2140 mm frame into a 56 mm thick timber frame for the new Thermawood drainage system. The test was completed at Facadelab in Auckland under the guidance of John Burgess from BRANZ.
System
This new innovation for Thermawood joins our current tested glazing systems designed for the 44 mm and 56 mm thick frames as a sliding door detail.
Previously, the Thermawood system was restricted to 16 mm IGUs into 34 mm frames and 20 mm IGUs into 44 mm thick frames. The latest test results mean the entire Thermawood range is now compliant and tested to AS 2047, as required by the National Construction Code.
The new system, as tested, was recessed to sit 1 mm inside the front of the into the
56 mm thick frame, so that the bottom bead did not protrude out the front of the frame like it does in the 44 mm thick frame, giving a cleaner look as present in the current sliding door detail.
Testing
The pressure in the booth is lifted to Extra High Wind Zone for a determined time, before being subjected to the Ultimate Limit State test where the pressure is lifted to 2130 Pa. This pressure is the equivalent of a major weather event; the likelihood of which is two per cent over a 50 year period.
This extreme test puts the frame, glazing system and IGU under immense pressure.“ I have been in the joinery and glazing industry for nearly 30 years and was surprised at the pressure the frame and IGU could withstand,” says Graeme Clarke, Director of Thermawood Australia.
The new 56 mm system uses the same beadings, inside rubber and outside rubber as with the 44 mm system, with the drainage
An installation manual outlining all steps involved in glazing the Thermawood system is available for all Thermawood fabricators as required.
Thermawood also specialise in retro-fitting double glazing and draft seals into existing timber frames with franchises available in Melbourne, Sydney and Adelaide.
Thermawood will have a stand at the upcoming AusFenEx16 where all Thermawood glazing systems will be on display, from Retro-fit, 34 mm, 44 mm and 56 mm systems.
Thermawood are an independent New Zealand owned glazing product supplier to the New Zealand and Australian window industry.

Researchers estimate that hundreds of millions of birds are killed each year due to collisions with glass on humanbuilt structures, making bird collisions one of the most significant causes of avian mortality globally.
It is the reflective and transparent characteristics of glass that create the danger for birds, as they cannot see it as a barrier. They fly towards sky and trees reflected by or on the other side of a window or railing and collide fatally with the glass. To prevent these collisions, glass must somehow be made visible to birds.
With the understanding that birds are able to see light in the ultraviolet spectrum, bird-friendly glass innovator, Arnold Glas, developed ORNILUX Bird Protection Glass. The glass has a patterned, UV reflective coating making it visible to birds while remaining virtually transparent to the human eye.
Tested in cooperation with ornithologists in both the USA and Europe, the glass has demonstrated to be an effective solution to mitigate bird collisions, especially in areas where transparency is a top priority.
ORNILUX offers a unique and innovative bird-friendly glazing solution— maintaining the aesthetic transparency of glass while creating visual markers alerting birds to a barrier.
