Timber Window FAQs

All Teal window joinery products are designed in collaboration with Architects/builders/homeowners and manufactured in our factory in South Grafton NSW, Australia. Whilst Teal manufacture windows to standard sizes, custom designed windows are readily made to meet customer requirements. Custom manufactured windows usually add only a small amount to the final cost if any.

Teal are experts in the design of custom windows. The team at Teal will willingly work with you to achieve your desired look and operational outcome.

All Teal windows are manufactured to Australian standards. For customer’s safety Teal Windows glaze all units to Australian Glazing Standard AS1288 (2006). Teal window products comply with AS 2047 (1999) as fully tested by the National Accredited Testing Authority (NATA) Laboratory. Teal’s windows exceed the required Australian Standard 2047 and achieve air-conditioning rating for the Air Infiltration test. The Air Infiltration test tests the volume of air gained or lost through a window unit with the benchmark set at 5 litres/m2. Teal’s window units all test less than 1litre/m2, substantially exceeding the benchmark. Teal Windows air-conditioning rating enables customers to achieve greater energy efficiency in their homes. Heating and cooling loss through windows can increase energy costs, a situation best avoided where possible. 

As a first step, the Basix rating for the building project needs to be established. Teal Windows and Doors can help customers determine the appropriate glass specifications for their project. Once a Basix rating has been established the desired glass type needs to be selected. Go to Teal’s Glass page for detailed information about glass. 

All Teal windows can be screened, even large bi-fold and stacker sliding windows. There are many different ways to screen window openings. Enquire about Teal’s Insect Screen Systems.

Some customers do not require window screens. Teal’s window screens are supplied at additional cost to window units.

Teal installs all hardware to all types of windows in-factory. Sourcing and selecting the same colour hardware across a range of window types is achievable but sometimes can be quite difficult. Hardware finishes available include stainless steel, satin or polished chrome, clear anodized aluminium, satin silver, PVD gold, polished gold, mahogany, black and other powder coated colours. Teal willingly assists customers to determine the hardware type and colour needs for their windows. Go to Teal’s Hardware page for further information.

All Teal timber windows need be stored on-site in a clean and dry area away from possible contamination by water, cement, lime, paint, acid, plaster, welding splatter and other contaminants. Windows stored on concrete that is not fully cured need to be elevated at least 50mm above the concrete to allow for sufficient ventilation. To comply with Teal’s joinery warranty timber must be sealed within 48 hours of delivery on-site and recoated after 90 days if not finish coated. Sealed Teal windows installed in masonry should be fully covered in builders plastic to protect the joinery from masonry debris during construction. 

All window units should be flashed during installation as per the Australian Building Code. 

Timber Door FAQs

All Teal door joinery products are designed and manufactured in our factory in South Grafton NSW Australia. Whilst Teal manufactures doors to standard sizes, custom designed doors are readily made to meet customer requirements. Custom manufactured doors usually add only a small amount to the final cost if any. 

Teal are experts in the design of custom timber doors. The team at Teal will willingly work with you to achieve your desired look & operational outcome.

All Teal doors are manufactured to Australian standards. For customer’s safety Teal Windows and Doors glaze all units to Australian Glazing Standard AS1288 (2006). Teal window products comply with AS 2047 (1999) as fully tested by the National Accredited Testing Authority (NATA) Laboratory. Teal’s doors exceed the required Australian Standard 2047 and achieve air- conditioning rating for the Air Infiltration test. The Air Infiltration test tests the volume of air gained or lost through a door unit with the benchmark set at 5 litres/m2. Teal’s door units test at 1litre/ m2, substantially exceeding the benchmark. Teal Windows and Doors air-conditioning rating enables customers to achieve greater energy efficiency in their homes. Heating and cooling loss through windows can increase energy costs, a situation best avoided where possible.

Teal screen doors can be manufactured with a range of screen types including security mesh. Go to Teal’s Screen Mesh page for further information. 

Some customers do not require screen doors. Teal’s screen doors are supplied at additional cost to door units. The cost of the screen doors is clearly marked on the quotation. 

Teal supplies builders and owners with either doors and jambs separate or doors hung in jambs. Teal can hang in jambs single, French and entrance doors in the factory on a high-quality butt or hirline hinges. Bifold, pivot and sliding doors are delivered in jams fitted in-factory. Hinged screen doors are supplied loose for fitting by builders. All doors and jambs should be fixed by a qualified builder to the Building Code of Australia.

All Teal timber doors need to be stored on-site in a clean and dry area away from possible contamination by water, cement, lime, paint, acid, plaster, welding splatter and other contaminants. Teal doors stored on concrete that is not fully cured need to be elevated at least 50mm above the concrete to allow for sufficient ventilation. To comply with Teal’s joinery warranty timber must be sealed within 48 hours of delivery on-site and recoated after 90 days if not finish coated. Sealed Teal doors installed in masonry should be fully covered in builders plastic to protect the joinery from masonry debris during construction. 

Where possible doors should be hung in jambs/frame prior to installation. Flashing as per the Australian Building Code needs to be fixed to jambs during installation. Door openings should be checked for square and plumb prior to the fixing of the door frame. A uniform gap should remain between the door and the jamb frame during and after installation. If the frame is not square and/ or the jambs are out of plumb the door(s) will not align properly in their jamb(s). Most doors require small adjustments due to wall variations on-site. It is important to fully support door sills to ensure proper operation of the door(s). 

Teal can supply and fit most of the hardware required for doors in-factory. An extensive range of hardware is available for doors and consequently, some builders and customers prefer to select and install their own door hardware. Sourcing and selecting the same colour hardware across a range of door types is achievable but sometimes can be quite difficult. Hardware finishes available include stainless steel, satin or polished chrome, clear anodized aluminium, satin silver, PVD gold, polished gold, mahogany, black and other powder coated colours. Teal willingly assists customers to determine the hardware type and colour needs for their doors. Go to Teal’s Hardware page for further information.

Timber FAQs

Teal manufactures windows and doors from both imported and Australian timbers. The most popular species are Western Red Cedar, PNG Rosewood and Kwila/Merbau as well as Accoya® and some Australian timbers such as Blackbutt, Spotted Gum and Rose Gum (see below). For more information go to Teal’s Timber page.

Teal manufactures windows and doors from Australian timber. The species of Australian timber used depends upon the setting or application the product is to be used in and the availability of the species. Contact Teal for more information.

Teal uses imported timber from sustainable sources in Canada, South East Asia and Papua New Guinea. Australian timbers are sourced from throughout the country although mainly from local mills. For more detailed information see Teal’s Timber page. 

All raw timber weathers with time. Raw timbers exposed to direct sunlight, wind and rain weathers at a much faster rate than unexposed raw timber. Exposed raw timber is likely to swell slightly, crack and discolour over time reducing the service life of the timber product. Applying a sealing coat followed by a number of finish coats reduces the effects of weathering. All exposed joinery needs to be regularly inspected and maintained with joinery in coastal areas requiring more regular inspections. Indicators of weathering include cracking, peeling and/or flaking of the finish coat, discolouration of the timber’s natural colour and dryness of the timber surface. Timber indicating weathering should be repaired and protected with fresh finish coats. Raw timber products dispatched from Teal’s factory must be sealed all over within 48 hours of delivery to comply with withTeal’s product warranty. No warranty applies to timber left unsealed. Teal most commonly applies a seal coat to windows and doors prior to dispatch from its factory. It is important that all surfaces on a window and/or door unit be completely coated at the same time, ie, on the same day. 

As a general principle, all timber surfaces should be seal coated. This includes the tops, bottoms and other concealed surfaces such as hinge and lock apertures. Timber end grain is often exposed to the elements on the bottoms and tops of windows and doors. Unsealed/finished end grain readily absorbs moisture leading to swelling, bowing, twisting and eventual rotting of the styles or vertical members of the window or door. It is important that all surfaces on a window and/or door unit be completely coated at the same time, ie, on the same day. 

For a variety of reasons, Teal advises customers to complete the finish coats of timber products after the window or door units have been installed. Units may need to be planed, chiselled and/or drilled during installation requiring the surfaces to be resealed. Units may inadvertently suffer minor scratches or dents during delivery or installation. Finish coating makes rectification of scratches or dents a much more difficult. Typically Teal applies 1 or 2 seal or primer coats prior to delivery. The seal coats require sanding prior to the application of the finish coats. Customers who are unsure about the correct finish to use should consult Teal for advice. Teal works with both customers and painters to achieve the all-important final appearance to its doors and windows. 

Customers who prefer finish coating to be applied in Teal’s factory should contact Teal about this optional extra. 

Teal strongly recommends the use of oil-based enamel coloured paint as an alternative to clear and/or stained finishing. Acrylic or water-based primer/sealer is only applied in-factory by request. Teal’s quick drying oil based primer/sealer will need sanding smooth prior to the application of finish or top coats. The application of dark coloured paint on exposed windows and doors should be avoided due to heat retention issues leading to timber warping and shrinking. Teal suggests customers consult a paint expert when finalising paint colours and brands. Teal does not endorse paint brands because the brand of coloured paint is a contributing factor in the appearance of the finish. Customers who are unsure about the correct finish to use should consult Teal, a professional painter or paint supplier for advice. Teal willingly works with both customers and painters to achieve the all-important final appearance to its doors and windows. 

Tip: Use the following method to determine the paint type if timber windows and/or doors are already painted. Apply a small amount of denatured alcohol (methylated spirits) to a clean white rag and rub onto the surface of the paint. Acrylic/Latex paint will come off on the rag. Oil/alkyd paint will not. 

The use of the incorrect timber finish or paint for a given window or door application can have adverse consequences. Teal recommends customers contact the finish or paint manufacturer to ascertain the latest information about the finish or paint the painter wants to use. Timber window or door units that are not exposed to the elements (internal) can usually be coated with most types of finish or paint. The following needs to be taken into account when finishing or painting window or door units exposed to the elements (external): 

  • Water-based or acrylic paints – Effectively wrap timber in a plastic coating preventing the timber from “breathing”. Some acrylic paints used on sliding surfaces can cause binding and sticking. Acrylic paints used in external applications void Teal’s joinery warranty.
  • Polyurethane, estapol and lacquer finishes – Dry to a rigid or hard finish preventing the timber from “breathing”. These finishes can cause timber to warp and split due to heat retention. Australia’s high levels of ultraviolet light shorten the life of these finishes. Use of these finishes in external applications void Teal’s joinery warranty. 
  • Natural oils and varnish finishes – vary in service life depending on the application. Oils used externally tend to have a short service life while oils used internally may last up to ten years or longer. External oil finishes may require re-application annually. If unsure contact Teal to discuss your use of oils or varnishes. 
  • Wax finishes – Form a barrier against water ingress and often contain fungicides to limit mould growth for example. Waxes can limit the future use of alternative finishes or paint. If unsure contact Teal to discuss your use of wax finishes. 

If unsure customers should contact Teal to confirm the type of seal coat used in the factory and compatible finishes. Customers should also contact the finish or paint manufacturer to ascertain the latest information about the chosen finish or paint. Different finish and paint types cannot be mixed due to chemical reactions shortening the life of the finish or paint. Acrylic or water-based paint should never be applied over oil-based primers or paints. The use of incompatible finishes or paints in external applications voids Teal’s joinery warranty.
