An external glass wall replaces solid cladding with a large expanse of glazing, usually framed in aluminium and fixed into the building structure. Done well, it opens a living area to the garden, lifts a street frontage or turns a rear extension into the brightest room in the house.
Because it forms part of the building envelope, an exterior glass wall has to resist wind, shed rain and manage heat as well as look good. We plan the frame, glass, sill and flashing details together, install to the approved drawings and check every seal before we leave.
In short: Hustle Installations designs and installs exterior glass walls for homes, builders and businesses. Price depends on wall size, frame system, glass performance, height and site access. We aim to respond to enquiries within one business day, and every project starts with a free measure and quote.
An exterior glass wall is more than a big window. It typically combines fixed glass panels, sometimes with sliding or hinged doors built into the same frame, and it carries wind loads back into the structure around it. The way the frame is fixed, how water is directed away at the sill and how the glass is sealed all decide whether the wall stays dry and draught-free for years.
Our job is to get those details right. We check structural openings and lintels with your builder, recommend frame sections and glass suited to the wall height and exposure, and coordinate flashings with cladding and roofing trades. Installation is planned around safe lifting of heavy panels, with protection for floors and surrounding finishes. For smaller glazing jobs or single panels, our glass installation team can help as well.
Most issues we are called to fix on external glass walls trace back to a handful of causes.
Poor sill and flashing details. Without correct sill drainage and flashings, wind-driven rain finds its way under the frame and into floors and wall linings.
Under-specified glass. Large panes of standard clear glass can turn a room into a hothouse in summer and a cold spot in winter. Performance glass makes a real difference on big walls.
Frames that are too light. Tall walls in exposed positions need frame sections that can handle wind pressure without flexing, rattling or leaking.
Rushed installation. Packing, fixing and sealing shortcuts show up later as sticking doors, cracked seals and draughts.
We tailor each exterior glass wall to the building, the orientation and how you want to use the space.
No two glass walls are priced the same, because size, height and performance requirements vary so much.

A large external glass wall involves heavy materials, several trades and weather exposure during installation, so planning is everything. We confirm the structural opening, frame and glass before ordering, book the installation for a suitable weather window and make sure the opening is never left unprotected for longer than necessary.

External glass walls must cope with wind pressure, rain and impact. In Australia, AS 2047 sets performance requirements for windows and external glazed doors, including structural, air and water performance, while AS 1288 covers how glass is selected and installed so it is safe for its size and location. Larger panes and glazing near floors and doorways often call for toughened or laminated glass.
On sites in bushfire-prone areas, AS 3959 can affect the glass and frame choices depending on the assessed BAL rating. Energy efficiency requirements may also influence glass selection on new homes and extensions. We work from your plans and any engineering or energy reports, apply these requirements where required, and talk you through the trade-offs between light, views, comfort and budget.
A glass wall is often the single most expensive element in an extension, and it is the one people notice first. When something goes wrong, the fix is rarely simple. Water staining on new flooring, condensation running down tall panes, doors that drag after the first summer and visible gaps where frames meet cladding are all problems homeowners and builders bring to us after another installer has left.
Coordination is the other big challenge. External glazing sits between framers, cladders, roofers and renderers, and poor communication can leave an opening exposed or a flashing out of sequence. We plan our work around the other trades and keep you informed from measure to handover.
What sets us apart:
We treat your glass wall as part of the building envelope, not just a big window.
Frames and glass are chosen to suit the height, orientation and weather your wall will face.
Heavy panels are handled with the right equipment and crew to protect people and finishes.
We schedule around builders, cladders and roofers so flashings and seals go in the right order.
You receive a written specification covering frames, glass and weatherproofing details.
We test doors, check every seal and clean the glass before we call the job complete.
Tell us what you need, where the project is located, and what outcome you want. We ask the right questions, review the scope, and provide a clear quote with no obligation.
We inspect access, openings, levels, existing frames, surrounding finishes, and any site-specific requirements. Accurate measurement helps prevent delays, gaps, and unnecessary rework.
We confirm the installation approach, materials, scheduling, and finish expectations. For Melbourne projects, we can also discuss thermal performance, double glazing, weather sealing, and BAL rating considerations where required or relevant.
Our team installs with care, precision, and safety. We focus on alignment, fixing, glazing, sealing, operation, and clean presentation.
Before we leave, we check the installation, clean the work area, and walk through the finished result. You get a tidy site and a result built to perform.
Exterior glass wall installation is the supply and fitting of large framed glazing that forms part of a building's outer wall. It may be fixed glass only or include sliding, stacking or hinged doors in the same frame. The installation covers framing, glazing, sill drainage, flashings and sealing so the wall is safe, weather-tight and comfortable to live or work behind.
It can if the glass is not chosen carefully. Large areas of plain single glazing let heat in during summer and lose it in winter. Double-glazed units, low-E coatings and good frame selection help a great deal, as does considering orientation and shading. We recommend glass for exterior glass walls based on how much sun and exposure each wall receives.
Most exterior glass walls use toughened or laminated safety glass, often in double-glazed units. Laminated glass adds security and noise reduction, and low-E coatings improve thermal performance. The exact glass type and thickness depend on panel size, height, wind exposure and location, following AS 1288 and AS 2047 where they apply.
Yes. Many glass walls combine fixed panels with sliding, stacking or hinged doors so you can open the space to a deck or garden. Building doors into the same frame system keeps sightlines consistent and simplifies weatherproofing. We will advise on door types and track options that suit the opening width and how you plan to use the area.
Manufacture usually takes several weeks once the specification is approved, depending on the frame system and glass. On site, a typical residential glass wall is often installed over one to three days, with larger or multi-storey walls taking longer. We confirm timing in your quote and book installation once the opening and other trades are ready.
Leaks are prevented through detailing as much as sealant. We make sure sills drain correctly, flashings lap the right way with cladding and roofing, frames are packed and fixed without distortion, and seals are continuous. Before handover we inspect every joint. Most leaks we see on other jobs come from missing or poorly lapped flashings.
Often, yes. Where an existing window wall or brick infill is being opened up, we coordinate with your builder or engineer on lintels and structural support, then remove the old frames and install the new glass wall. Careful sequencing keeps the building secure and weatherproof during the changeover.
Yes. We protect floors and finishes during the work, remove old frames, glass and packaging, and clean the new glass and frames before handover. Any debris from strip-out is taken away. You should be able to start using the space as soon as the exterior glass wall installation is signed off.
Yes. Glazed frontages, office entries and street-facing walls are common commercial applications. These projects often need heavier frame sections, laminated glass for security and careful scheduling to limit disruption to trading. We can work after hours where practical and coordinate with building managers on access and safety.
