All of Windoor Joinery’s window and door products are manufactured from solid timber, including Accoya, Western Red Cedar, Blackbutt and Rosewood. For more information visit

Western Red Cedar




Bushfire Rating

For those who live in bushfire-prone areas, Windoor Joinery is able to manufacture your windows and doors from bushfire resistant timbers up to BAL 29.

Some of the bushfire resistant timbers used by Windoor Joinery include Spotted Gum, Blackbutt, Rosewood and Merbau. We can also utilise recycled timber. For more information on bushfire resistant timber and Windoor Joinery products that suit a bushfire prone area, please contact us.

Wind Classification

Windoor Joinery’s windows and doors are typically glazed to meet the standards set by the N2 wind classification system whereby a house must stand up in winds of 26m/sec (93.6 kmh) and gusts of 40m/sec (144 kmh). This classification is relevant to most of NSW.

If a higher classification is needed, Windoor Joinery can cater to your needs. Please contact us to find out more.

Glass and Glazing

Float Glass

Float Glass is manufactured by melting sand, soda ash, dolomite and limestone together and produces a continuous glass ribbon up to 3660mm wide. This flows from the furnace and ‘floats’ over a bed of molten tin. It is then carefully cooled to anneal the glass – a process which modifies the internal stresses enabling it to be cut and which maximises its potential mechanical resistance.

The float glass process is renowned for flatness and optical clarity. It is available in clear, toned, high performance toned, ultra-clear low iron glass and Low E thermal performance pyrolytic coated. Viridian installed a CVD coater to the float line, which enables online Low E coatings to be applied whilst the glass is in its molten stage of production.

Decor Patterned Glass

This involves embossing a pattern into the glass during manufacture by passing the semi molten glass through a set of rollers prior to annealing. One side remains smooth whilst the texture is applied to the other side. A square wire mesh can also be included.

Insulating Glass Units

Also known as double glazed units, where two or more panels of glass are bonded to a perimeter spacer of either metal or thermoplastic spacer (TPS). Either air or argon gas fills the space between the glass panes. Their primary benefit is insulation and solar control. Most types of glass can be incorporated into an insulating glass unit.

Laminated Safety Glass

Comprises two or more layers of glass permanently bonded together with an interlayer or resin. If broken, the interlayer is designed to hold the glass together. Virtually all glass types can be laminated, and the thickness and type of interlayer can be varied to provide resistance from airborne (like a bomb) or physical attack. Normal laminated glass can be cut and further processed.

Toughened Safety Glass

Float or Décor Patterned glass is placed in a roller hearth toughening furnace. The glass is heated then rapidly cooled, resulting in the glass retaining high compressive stresses. Fully toughened glass is four to five times stronger than ordinary glass and if broken forms small granules. Heat strengthened glass has a lower residual stress and is two times stronger than ordinary glass. It is not a safety glass and if broken it forms large pieces. Toughened and heat strengthened glass cannot be cut and both are resistant to high differential temperatures (180–250°C).
