How to Choose Jason Sliding Windows for Your Home

Choosing an aluminium sliding window looks straightforward until you compare the panel layouts. With Jason sliding windows, the right choice involves more than width and height. You also need to know which panel opens, which direction it slides and whether fixed or low lites belong in the design.

Most questions we hear in our Guildford showroom are not about whether a sliding window will work. Customers want to know which of the nine configurations suits their opening and how to avoid ordering the wrong setup.

This sliding window buying guide works through those decisions in the order you need to make them. We will compare the available configurations, then cover sizing, opening direction, frame colours, flyscreens, glazing and project requirements. If you are choosing sliding windows for a Perth renovation or new build, you will know exactly what to check before placing your order.

Which Jason Sliding Window Configuration Should You Choose?

A single or double slider suits a straightforward opening, while a multi-panel configuration suits a wider opening. Choose a low-lite design when you need fixed glass below. Before ordering from our range of Jason sliding windows, confirm the measurements, airflow and moving-panel position shown on the product diagram.

Ross’s stocks nine Jason Windows sliding windows, grouped into three useful categories. This makes it easier to narrow the options without getting caught up in similar product names.

Configuration group	Product	What the layout provides	Consider it when
Straightforward	Single Sliding Windows	One sliding section paired with fixed glass	You want a familiar sliding arrangement for a straightforward opening.
Straightforward	Double Sliding Windows	A double-sliding arrangement	You want more than one operable sliding section.
Wider multi-panel	Centre Sliding Window with Two Fixed Lites	A centre sliding arrangement with a fixed lite on each side	You have a wider opening and want a balanced three-part layout.
Wider multi-panel	Single Sliding Window for 2nd Panel with Three Fixed Lites	A four-panel arrangement with the second panel designated as the slider	You need one operable panel across a broad expanse of glass.
Wider multi-panel	Double Sliding Window with Two Outer Fixed Lites	Two sliding sections between fixed outer lites	You want central opening sections framed by fixed glass.
Low-lite	Sliding Window Over Low Lite	A sliding window above a fixed lower section	The opening design calls for fixed glass below the slider.
Low-lite	Single Sliding Windows Over Low Lites	A single sliding arrangement above fixed low lites	You need a broader lower row of fixed glass beneath the sliding section.
Low-lite	Sliding Window with Two Fixed Lites Over Three Low Lites	A three-part upper arrangement above three fixed low lites	You have a large opening that needs defined upper and lower rows.
Low-lite	Double Sliding Window w/ Fixed Lite over Three Low Lites	A double-sliding upper arrangement with a fixed lite above three low lites	You need two operable upper sections with a fixed lower row.

Start with the simplest configuration that provides the opening and airflow you need. Choose a wider multi-panel or low-lite layout only when the opening requires it. Check the product drawing to see how the sliding sash relates to the fixed glass.

Single and Double Sliding Windows

Single and double sliders are the natural starting point for a conventional opening. The sliding sash moves horizontally, while a fixed lite does not open.

The words “single” and “double” describe the sliding arrangement, not the glass thickness or number of panes. Check the product diagram to confirm which panels move.

Customers often begin with the layout they prefer visually. Once we ask where they want the airflow and which part of the window must open, the shortlist usually becomes much clearer.

Centre and Wider Multi-Panel Configurations

Wider sliding window configurations combine operable sections with fixed lites. The fixed glass balances a broad opening while the sliding sections provide ventilation where you need it.

Pay close attention to the centre slider and the two four-panel options. Their moving panels occupy different positions, so let the product diagram have the final say.

If you have not decided whether part of the opening needs to operate, our comparison of sliding windows and fixed windows explains the practical differences. If you are also considering vertical operation, compare sliding windows and double-hung windows before settling on a layout.

Sliding Windows with Low Lites

A low lite is a fixed glazed section below the main window arrangement. These types of sliding windows suit openings that need a distinct lower row of glass beneath the sliding section.

Ross’s offers four low-lite configurations, from a slider over one lower section to broad six-panel arrangements. Check the complete diagram, dimensions and panel positions carefully.

A low lite does not automatically improve safety or energy efficiency. Those requirements depend on the window’s location and project specification. Once you have the right layout, confirm that it comes in the size you need.

How to Choose the Right Sliding Window Size

Measure the actual opening and check the project specifications. Do not estimate from the old window or assume every configuration comes in the same dimensions. Size options vary between products.

Measure Before You Select a Product

An aluminium sliding window buying guide can help you shortlist a product, but the final choice still depends on accurate measurements. Work through these checks in order:

1. Confirm whether you are measuring a replacement opening, a new renovation opening or a new-build specification.
2. Follow our guide to measure your windows correctly, recording the required width and height.
3. Match those measurements to the size options listed for your chosen configuration.
4. Ask your builder or installer to confirm the opening and installation requirements before you place the order.

Ross’s supplies the window but does not provide custom installation. Your builder or installer must confirm that the selected product suits the prepared opening.

Standard Sizes and Manufactured Orders

There is no single chart of standard sliding window sizes that applies across all nine configurations. Each product page lists the combinations available for that particular design.

We keep an extensive range in stock, with Silver Lustre commonly the most readily available colour. Allow 10–15 business days for manufactured sizes and colours, and confirm timing before scheduling other work.

Once you have confirmed the configuration and size, the next detail is easy to overlook but just as important: which direction should the sliding sash open?

Should Your Sliding Window Open Left or Right?

We define the sliding window opening direction while you are viewing the window from outside the home. Choosing it while standing inside reverses your perspective and can result in the wrong product being ordered.

Ross’s uses two clear options: LEFT to RIGHT and RIGHT to LEFT. Stand outside, face the proposed window opening and picture where the sliding sash should move. Mark that direction on your measurements or building plan before making your selection.

Terms such as left-opening sliding window and right-opening sliding window can be interpreted differently. Use the exact LEFT to RIGHT or RIGHT to LEFT wording shown on the product page rather than relying on those informal descriptions.

Also consider where you want the opening for airflow and easy access. Nearby walls, paths, furniture and internal fittings may affect which direction works best. With the functional choices confirmed, you can move on to the frame colour, flyscreen and glass.

Choose Your Colour, Flyscreen and Glass Options

Once the configuration, size and opening direction are settled, you can turn to the visible finishes and optional extras. Colour, flyscreen and glass choices affect how the window looks and performs, but they cannot make the wrong configuration suitable for the opening.

Six Standard Frame Colours

Each window in the range is available in six standard powder-coated frame colours:

• Night Sky
• Storm Front
• Silver Lustre
• Pearl White
• Charcoal Lustre
• White Lustre

Silver Lustre is commonly stocked, while some sizes or colours need to be manufactured. Allow 10–15 business days for these orders and confirm current availability before scheduling your project.

The flyscreen frame can be colour-matched to the window. Digital colours can differ from the finished powder coat, so view a physical sample when matching existing frames or exterior finishes. Our guide to choosing the right window colour can help you compare the six options.

With or Without an Aluminium Mesh Flyscreen

Ross’s gives you two clear choices: With Aluminium Mesh Fly Screen or Without Aluminium Mesh Fly Screen. If you are comparing sliding windows with screens against windows without them, think about how often you want ventilation while keeping insects outside.

An aluminium mesh flyscreen is an insect screen. It is not a security screen and cannot be relied upon for fall prevention. Fibreglass, steel, Migi mesh and Jason security screens are available by special order only, subject to confirmation.

Standard Toughened Glass and Special-Order Glazing

Our standard specification is a minimum of 5 mm Grade A Toughened Safety Glass. This is the standard glass used across the windows we sell.

Low-E, double glazing, tinted, obscure and laminated glass may be available by special order. Availability, pricing and lead times depend on the chosen window. Check the glazing’s rated performance before relying on it for a particular thermal, acoustic or privacy result.

The final product checks cover the BreezeLock, BAL suitability, upper-storey safety and warranty.

Standard Features, BAL Ratings and Warranty

The same core features apply across the range, but compliance depends on the property, window position and installation. Check them against your project requirements before ordering.

BreezeLock and Concealed Fixings

Each Jason Windows sliding window includes a BreezeLock with three positions: closed, approximately 50 mm open and approximately 100 mm open. The narrow settings allow airflow while the sash remains locked in position.

BreezeLock provides controlled ventilation, but it does not make the window burglar-proof or replace a tested security screen. Concealed screws and rivets keep the frame finish clean.

For a broader look at everyday performance, maintenance and ventilation, read about the advantages of aluminium sliding windows.

BAL Ratings and Upper-Storey Safety

Our standard range is suitable for BAL Low, BAL 12.5 and BAL 19 with aluminium flyscreens. AS 3959 sets construction requirements for bushfire-prone areas, while the BAL needed depends on the site assessment. Check the applicable Bushfire Attack Level requirements before choosing the window.

Higher-rated Jason options may be available by special order. Our standard online range is rated only to BAL 19, so ask us to confirm higher requirements.

Certain upper-level windows also require compliant fall-prevention measures. Standards Australia explains the fall-prevention requirements for openable windows. A standard aluminium mesh flyscreen is an insect screen, not a compliant barrier or window restrictor.

I always recommend confirming BAL and upper-storey requirements before ordering. Changing a specification later can affect the product choice and project timing.

Warranty Coverage

These windows have a 10-year structural warranty and a separate two-year warranty on moving parts. The 10-year period does not cover every component. Correct installation and the published terms govern coverage.

With those requirements checked, you can run through the complete order one final time.

What to Check Before Ordering

Choosing sliding windows becomes easier once every decision is written down. Before paying or approving a quote, check each detail against the selected product page.

• Confirm the exact Ross’s product name and check the complete configuration diagram.
• Match your opening measurements to the sizes offered for that product.
• Select LEFT to RIGHT or RIGHT to LEFT while viewing the window from outside.
• Choose one of the six standard frame colours, using a physical sample if accurate colour matching matters.
• Confirm whether you want the window with or without an aluminium mesh flyscreen.
• Confirm the standard glazing specification or any special-order glass requirements.
• Check the project’s BAL rating and any upper-storey fall-prevention requirements.
• Confirm whether the product is in stock or requires the 10–15-business-day manufacturing period.
• Confirm your collection, delivery and installation arrangements before finalising the order.

Ross’s supplies the window but does not provide custom installation. Ask your builder or installer to verify the opening, selected product and installation requirements. This can prevent a small measurement or direction error from delaying the project.

The following questions cover the remaining details customers often want confirmed.

Frequently Asked Questions

These are the details customers most often want confirmed before ordering. The answers apply to the standard range offered by Ross’s.

Which Jason Sliding Window Is Right for Your Project?

Choosing the right window starts with the opening itself. A single or double slider will suit many straightforward openings, while wider multi-panel and low-lite configurations cater for more specific layouts.

Once you have shortlisted the configuration, check the size and moving-panel position against the product diagram. Then select the opening direction from outside before confirming the frame colour, flyscreen, glass and project requirements. With nine configurations available, each decision must work with the one before it.

Compare all nine configurations online, or bring your measurements and plans to our Guildford showroom at 57 James Street. We can help you identify the closest standard option and confirm whether your preferred size, colour or glazing requires a manufactured or special order. Your builder or installer should make the final check before you place the order.
