Since the weight of the glass will only be supported by the head and the sill, a silicone joint will significantly lessen the strength of your window. Silicone joints are still a viable glazing option, however they need to be implemented carefully and with prudent consideration to the wind load and local topography.

The reveal is a timber surround fitted to the fin of the window or door and used for installing the product into timber framing.  The reveal becomes the internal frame of your window otherwise known as the ‘window sill’ or door covering the stud. The architrave attaches to the reveal to cover the gap between the reveal and the plasterboard (or internal lining).  A variety of reveal sizes are available depending on your construction type. Refer to our Reveal Size Chart for more information and also see our Measuring Diagrams for brick and clad home applications.

The size of the reveal is the combined width of the timber stud, the internal lining and cavity (for brick veneer). Wideline recommends you discuss reveal sizes with your builder before organising quotes or ordering windows.

Every house is different, are you replacing an existing window, extending or building a new house? What construction type are you using? Read our Guide to getting measurements right. 

All of these things will influence how to measure your window, therefore Wideline highly recommends seeking the assistance of a licensed builder to measure your window and door openings. This will ensure you receive the right product and pricing when requesting a quote and placing an order.

This question can have multiple answers depending on your location. Advances in glass has also meant there are many options for thermal insulation these days.

Double glazed glass provides good thermal insulation. Due to the air space between the two panels, less heat is transferred between the exterior and interior of your home. This means that in winter less heat is lost to the outside, and in summer less heat is allowed inside.

There are other glazing options available which can help with thermal insulation. Please look at the energy efficiency section of the website for more details.

Glass however is not the only consideration when it comes to thermal insulation. The type of material will also impact on thermal insulation, timber will generally have better insulation properties than a commercial aluminium frame for instance. Please speak to your local Wideline showroom for further information on thermal insulation solutions.

In an area that is subjected to a large amount of wind and rain, it is best to use a 300pa sill. This will be of great assistance in sealing your home. Your Wideline Sales representative will be able to assist you more in this area.

In terms of sound insulation, the most effective glass is laminated glass, as it absorbs sound more effectively than any other variety of glass.

Your local council will be able to give you a definite answer on this query.

Yes, you can! You will want to have your builder measure and quote for you to install a door in place of a window, as structural adjustments to the window cavity will need to be made to accommodate a door.

Some of our handles can be colour matched to your aluminium frame colour for an additional cost. This will however depend on the colour that you require and the type of handle you have chosen. In our Horizon range the handles come in black as standard. It is best to chat to your sales representative when asking for a quote to see what colour options are available to you.

All our windows are made to order. Our architectural Paragon range allows great design versatility that is adaptable for each project. With a variety of options available, Wideline’s windows and doors can be custom made to perfectly match your home's architectural style. Contact our friendly team to see how we can make the perfect window for you.

Wideline timber products are sent out in a raw natural finish ready to be stained or primed ready for painting. A natural finish allows you to decide the stained look you want. If you order windows with a natural finish you will then need to stain the product or prime and paint within a month of receiving the windows and doors. A pre-primed finish requires the product to be painted and will still require an undercoat and an application of a final finish.

Easy. Just get in contact with one of our sales team to request a quote. Either visit a showroom or submit a quote request online. Even if you don’t have building plans yet, that’s OK, we'll ask you the right questions to produce a thorough quote. Once you submit an online request, one of our sales representatives will call you to discuss your ideas, then send you the quote by email. 

Timber products must be sealed as soon as possible, at least within a month of delivery. Apply two coats of stain, paint or sealer for a lasting finish. Exterior quality finishes must be applied to all products exposed to rain and direct sunlight. Timber must be primed before painting. It’s important that the top and bottom of doors are sealed well to prevent moisture from seeping into the end grain.

It is no longer a question of timber OR aluminium, many houses now use a mix of materials depending on the look and feel for each room. When choosing between timber and aluminium, consider the style of the house, maintenance required, energy rating, BAL rating and price.

The main points to consider when choosing between timber and aluminium are the maintenance, look and material qualities. Timber windows and doors require more maintenance but offer greater energy efficiency than aluminium. Aluminium requires very little maintenance and can achieve a better bushfire rating. The visual difference between timber and aluminium windows is a personal preference.

Our SmartGlass is a single glazed, Low-E insulating glass that is designed to keep your house cool during summer and warm during winter. It also comes in neutral and grey toned options which offer direct sunlight protection for those exposed windows and doors. You can read more about our glass options here.

Glass is a major element in your building’s design because it provides light, ventilation, has the ability to reduce external noise and improves security. Read more about glass options here to choose the right glass for your requirements.

NatHERS stands for Nationwide House Energy Rating Scheme. NatHERS enables windows and doors to be rated and labelled for their annual energy impact on a whole house, in any Australian climate.

NatHERS assesses a home’s potential heating and cooling energy use. The scheme uses a star rating system to rate the energy efficiency of a home, improving liveability and helping home owners save on energy bills through smarter design planning.

NatHERS star ratings meet the mandatory energy efficiency requirements of the National Construction Code of Australia.

Safety glass is glass that is laminated or toughened. It is required in bathrooms as well as in doors or windows where there is a risk of human impact with the glass surface.

SmartGlass™ is a Low-E glass that has insulated single glazing for comfort. It is also available as safety glass.

The placement and size of windows and doors in your home will affect the architectural design as well as the overall comfort of your home. Have a look at our window planning guide to help you decide the best window placement and sizes for your home. With the right type of glass, windows and doors can have larger panes of glass and still maintain energy efficiency standards.

Many of our Merbau species timber products are capable of achieving BAL-29, with different combinations of glazing and seals. Read more about Wideline Windows & Doors Bushfire Rated products here. Or get in touch with our team for specific information regarding your project.

We recommend that you use a high quality, external timber stain or paint. The colour of stain or paint you use is your personal preference, but the greater the weather exposure, the lighter the colour should be. Opaque stain finishes will give more UV protection and longer life than semi clear finishes. Gloss finishes also give more protection.

Wideline uses sustainably sourced Western Red Cedar or Merbau timber. Western red cedar is a hard wearing softwood that is stable under almost any climate condition. It will not warp and is naturally resistant to insects. Merbau is a dense hardwood used for its strength, durability and colour. Some products are also offered in Meranti timber species. You can view more information about sustainably sourced timber and green-tag certification here.

Our windows and doors are installed in many builders’ display homes, and they can also be seen at our window and door showroom’s in Sydney, Central Coast, Newcastle and Port Maquarie.

The areas of the home where safety glass is required has increased over the last few years. The use of safety glass is determined by the size and location of windows and doors. Safety glass is best used in any area where there is a risk of impact with a glass surface. Areas of the home that must use safety glass include around stairs, all glass doors, bathrooms and areas with full glass height that can be mistaken for openings.

The Building Code of Australia has window regulations for openable windows, to reduce the risk of people falling from windows. By law, windows above the ground floor with a fall of two meters to the ground, need to be fitted with either a device to restrict the window’s opening, or a suitable barrier. We believe windows should be able to operate as they are intended to, without risking the safety of your family, so we created the SafeLine® fall prevention screen.

Window restrictions and options available with each window range:

 - With our Horizon window range, you can either have window restrictors added which will prevent your window from opening more than 100mm, or install SafeLine® fall prevention screens.

- If you are using the Paragon range, you will need to use SafeLine® screens on upstairs openable windows.

- For our Natura range, the window opening will require the use of a window restrictor.

Our SafeLine® fall prevention screens are made with resilient mesh for maximum strength and let your window operate as they were intended. Speak to us on 1300 943 352 about having SafeLine® safety screens installed on your windows.
