How to Order Windows Online in Australia: A Step-by-Step Guide

Ordering windows online might sound daunting — these are precision-made, custom-sized building products, after all. But with the right supplier and a bit of preparation, the process is straightforward, and you can have Australian-made windows delivered to your door without ever setting foot in a showroom.

This guide walks you through exactly how to do it, using Window & Door Supplies as an example — a trusted online supplier of Carinya aluminium windows and doors, delivering across Brisbane, Gold Coast, Sunshine Coast, Northern Rivers, Coffs Harbour, Sydney GMA, and beyond.

Step 1: Measure Your Opening Correctly

This is the most important step, and it's where most mistakes happen. Before you browse a single product, you need accurate measurements.

What to measure:

• Stud opening — the rough framed opening in your wall (height x width). This is what WDS uses for their "reveal" window sizing.
• Check for square — measure diagonally across both corners. If measurements differ by more than 5mm, your opening may need squaring up before installation.
• Depth of reveal — the thickness of your wall, which affects what reveal depth you'll need.

Measure twice. Order once. Custom aluminium windows are made to order and cannot be returned if you get the dimensions wrong.

Step 2: Choose Your Window Style

Once you know your opening size, decide which window style suits the room and your climate. At windowanddoorsupplies.com.au, the main options are:

• Sliding Windows — popular for living rooms, bedrooms, and anywhere you want a wide view with easy operation. Available from $335.
• Awning Windows — hinge at the top and stay open in rain. Great for bathrooms, laundries, and Queensland homes.
• Louvre Windows — adjustable blades for maximum ventilation. A subtropical favourite.
• Bi-Fold Windows — fold completely open for a seamless indoor-outdoor connection.
• Gas Strut Servery Windows — prop open for alfresco entertaining areas and kitchen serveries.
• Fixed Windows — non-opening, for light and views where ventilation isn't required.
• Double Hungs — both sashes slide vertically, a classic choice for heritage-style homes.

Not sure which to pick? WDS has a Product Selection guide on their website to help you decide.

Step 3: Select Your Size

WDS offers windows in a range of standard sizes. Each product listing shows the stud opening dimensions — the rough framed opening your windows need to fit into.

For example, the Carinya Sliding Window range includes sizes from H600 x W600 right through to H1200 x W1800. If none of the standard sizes match your opening, WDS also offers a Custom Orders service — simply contact the team with your measurements and they'll quote accordingly.

Step 4: Choose Your Glass Type

Glass selection has a big impact on comfort and energy efficiency — especially in Queensland's climate. WDS offers several options across the Carinya range:

• Clear glass — standard, cost-effective option for low solar-exposure areas.
• Grey tint — reduces glare and solar heat gain. Good for north and west-facing windows.
• Low-E glass — reflects infrared heat while allowing natural light through. Ideal for reducing air conditioning load in summer.
• Clear double glazed — improves thermal and acoustic performance. Good for street-facing rooms or those needing extra insulation.
• Grey tint double glazed / Low-E double glazed — the highest performance options, combining tint or Low-E coating with double glazing.

Not sure which glass is right for your situation? WDS has a dedicated Glass Types guide on their website.

Step 5: Pick Your Frame Colour

The Carinya aluminium range comes in three colour options:

• Pearl White — clean and classic, suits most homes.
• Custom Black — bold and contemporary, increasingly popular in modern builds.
• Custom Colour — powder-coated to a colour of your choice for a tailored finish.

Consider your home's exterior palette, and check whether your local council has any colour requirements for heritage zones.

Step 6: Add Screens

Queensland homes need screens. WDS offers four options:

• No screens — if you're installing your own or the opening is already protected.
• Flyscreens — standard insect protection.
• Diamond grille — a fixed aluminium security grille with insect mesh.
• Stainless steel security screen (Invisi-Gard) — the top-tier option. Invisi-Gard is an award-winning security screen that's virtually invisible while providing serious intrusion resistance. Ideal for ground-floor windows in any suburb.

Step 7: Add to Cart and Check Out

Once you've configured your window — size, glass, colour, screens — simply add it to your cart on the WDS website. You can order multiple windows in one transaction, mixing styles and sizes as needed for your project.

At checkout you'll enter your delivery address. WDS delivers across South East Queensland, Northern NSW, and Sydney GMA with regional delivery runs scheduled regularly.

Step 8: Confirm Lead Time and Plan Your Installation

Current lead times at WDS are 6–8 weeks for the residential Carinya range — which is standard for custom-made aluminium windows in Australia. Use this time to ensure your rough openings are framed and ready, and to line up your installer.

WDS has an Installation guide on their website, and their team is available on 02 5631 1755 if you need guidance on anything from measuring to installation prep.

Need Something Non-Standard?

If your project involves unusual sizes, commercial specifications, or a high volume of windows, WDS's Custom Orders service has you covered. They can also supply commercial-grade windows from the Alspec Altitude and Proglide ranges on request.

Ordering windows online in Australia doesn't have to be complicated. Measure carefully, choose the right style and glass for your climate, and pick a supplier who knows Australian conditions inside out. Start browsing the full range at windowanddoorsupplies.com.au.
