SPECIFICATIONS

Windows and doors are so important to the design, functionality and efficiency of a home. They provide access, flood the home with sunlight and ventilation, can assist with reducing energy bills, and provide security and peace of mind.

Timber is already a natural insulator, and we can increase the efficiency of your home by making your windows double-glazed which provides improved insulation from the heat and cold as well as significant noise reduction perfect if your property is near a busy road or the railway.

We also promote the environmental and energy performance benefits with options for window energy rating systems.

Why we use Timber

We use timber for our windows and doors because timber is natural and we LOVE IT.  Timber is so versatile and we can achieve high levels of performance and durability from the use of timber in our products. Timber is made from carbon drawn from the atmosphere.  This carbon would otherwise be adding to the greenhouse effect.  Using timber for windows and doors stores the carbon for the life of those products.  

 

As timber ages, it does so naturally and doesn't break down into environmentally damaging materials.  Unlike other man-made materials used in the manufacture of windows and doors, timber is renewable and sustainable if sourced appropriately.

We only use timbers that are appropriate for windows and doors to ensure your products stand the test of time - never any veneered or engineered timbers - solid select grade timber only.  Where Cedar is requested we only use Western Red Cedar which will remain dimensionally stable under most weather conditions, is not prone to shrinkage or swelling and is termite resistant.  We know of other manufacturers who are using Surian Cedar to build windows and doors.  This timber is suited to decorative internal purposes only and should not to be used for joinery items such as doors and windows.  It is an inferior timber and if used for windows and doors expect to get between 5-10 years out of your investment. 

 

We use both imported and Australian timbers sourced from accredited suppliers who use FSC and Rainforest Alliance products.

About FSC and Rainforest Alliance products

The Forest Stewardship Council (FSC) is an independent, non-governmental, not-for-profit organisation established to promote environmentally appropriate, socially beneficial and economically viable management of forests in Australia and countries supplying the Australian forest products market.

The Rainforest Alliance offers forest product companies voluntary independent third-party verification of legal status for the sources of raw materials for their products. They are recognised by Greenpeace International as the top-ranked verification program.

Timbers we use

 

Imported

Western Red Cedar 

 

Is the most commonly used timber for windows and doors. It is an extremely robust, but soft timber. It has a stable grain structure and can be very pale brown to very dark brown in colour.  BAL 29 Fire Rating (in a tested system).

Rosewood

 

Is the popular name given to the ornamental wood of tropical trees. The heartwood of the tree is where the reddish-brown colour of timber comes from. Rosewood is a strong and heavy timber with a close and mostly straight grain. BAL 19 Fire Rating.

Merbau

 

Is a very stable hardwood that is a popular choice as it is resistant to termites and decay. Merbau is dark reddish brown in colour. It is prone to leach when a clear finish is applied. BAL 29 Fire Rating.

Accoya

 

Is a stable, sustainable and low maintenance timber. Your windows and doors are classified as carbon negative over their 50+ year life cycle. Accoya is a pale honey colour with performance characteristics of the most robust tropical hardwoods. BAL 19 Fire Rating.

Australian

Blackbutt

 

Is an extremely versatile hardwood with colours ranging from golden yellow to pale brown. It is however prone to a small amount of twisting and shrinking so not as stable as some of the other timbers. BAL 29 Fire Rating.

Spotted Gum

 

Is a very tough hardwood with colours ranging from light brown to dark brown. It is however, like Blackbutt, also prone to a small amount of twisting and shrinking so not as stable as some of the other timbers. BAL 29 Fire Rating.

River Red Gum

 

Is a fast growing readily available hardwood that has become one of the most widely planted Eucalypts in the world. Known for its durability and strength River Red Gum has a distinct red colour range from pink to almost black. BAL 29 Fire Rating.

Bushfire Rating

All new buildings and proposed additions to existing buildings are assessed for bushfire attack levels (BALs), as per Australian Standard – AS 3959.

There are five levels:

  • BAL 12.5: Low

  • BAL 19: Moderate

  • BAL 29: High

  • BAL 40: Very High

  • BAL FZ: Flame Zone

These levels are based on the threat of fire to the building, as the level of threat increases, so does the restrictions on which building materials can be used. Where restrictions do exist, timber is allowed to be used in the lower levels, providing it meets specific criteria.

The following material has been sourced from www.timber.net.au

There are 2 main criteria:

  • For some applications, AS 3959 indicates that there are no requirements or permits the use of timber. For such applications any timber may be used (where appropriate) provided that the timber meets the requirements of all other standards and codes that apply to the construction. 

  • For some applications, AS 3959 restricts the use of timber to a fire-retardant – treated timber. However, the standard does provide that some timber species are capable of meeting the required parameters (for resisting fire) without having to be subjected to fire retardant treatment. Again, the timber used must meet the requirements of all other standards and code that apply to the construction.

The following timber species have been tested and found to meet the required parameters without having to be subjected to fire retardant treatment:

- Blackbutt 
- Merbau 
- Red Ironbark 
- River Red Gum 
- Silvertop Ash 
- Spotted Gum 
- Turpentine
