uPVC windows have been gaining popularity in the Australian design and construction industry due to their durability, energy efficiency, and low maintenance requirements.
Please visit our website for more information on this topic.
Thermoteks uPVC window and door systems are manufactured locally at our Melbourne facility, harnessing world-class German engineering from uPVC profile leaders aluplast.
This partnership allows us to provide competitive pricing and a unique level of customisation for the Australian climate and market. It also assists in significantly reducing our carbon footprint and keeping embodied emissions low.
uPVC, short for Unplasticised polyvinyl chloride, takes its name from the absence of chemical plasticisers in its composition. Instead, uPVC is made from robust impact modifiers and reinforcing fillers.
During the manufacturing process, elongated polymers resembling strands of spaghetti intertwine, reinforcing the material. Then the introduction of impact modifiers binds these polymer strands together for strength.
This makes it a uniquely durable material for window and door frames. uPVC frames have remarkable resilience against damage and extreme weather. They also require little ongoing maintenance.
uPVC also has the highly unusual quality of becoming stronger the more it is recycled. Upon its initial recycling cycle, uPVC can attain up to a 6% increase in strength. The next four or five times its recycled, it will get stronger, albeit by a smaller amount each time.
This gives uPVC a surface hardness on par with aluminium, without needing to be thermally broken like the latter for energy efficiency.
uPVC has outstanding properties when it comes to insulation and doesnt conduct heat, making it perfect for window frames. Its also much more affordable than thermally broken aluminium.
The design and construction of uPVC windows is a meticulous process that harnesses engineering precision to create windows that are not only aesthetically pleasing but functional and long-lasting.
Lets look more closely at the ten key steps involved in the design, construction, and installation of Thermoteks uPVC window and door systems.
The construction of uPVC windows begins with the fabrication of the window frame. As discussed, using a rigid and durable material like uPVC gives the frame resistance to weathering, corrosion, and impact.
The process starts with extruding uPVC profiles, which are long, hollow sections that will form the main framework of the window. These profiles are created through a process called extrusion, where uPVC material is melted and forced through a specially designed die to form the desired shape. This allows for intricate designs and profiles to be produced.
Thermotek has a strategic partnership with aluplast, whose German-engineered profiles from are made from up to 70% recycled uPVC. We exclusively use aluplast as our extrusion supplier due to their exceptional engineering, innovation, and commitment to the environment.
The extruded uPVC profiles are then cut to the required lengths based on the window specifications. These profiles come in various shapes and designs, catering to different architectural styles and functional requirements.
The window frame holds the window sash that allows the opening and closing of the window and also fastens the window to the building structure.
The cutting process is carried out in our Melbourne facility using precision cutting machinery to ensure accurate dimensions.
To create a seamless and strong frame, the cut uPVC profiles are assembled using a corner welding technique. This involves joining the profiles at the corners through a process known as heat welding or fusion welding.
The uPVC material is heated at the corners, causing it to melt and fuse together, forming a solid and durable joint. This welding process enhances the strength and rigidity of the window frame.
To further reinforce the uPVC window frame, galvanized steel inserts are placed within the hollow cavities of the profiles. The inserts are strategically positioned within the frame to provide optimal support.
These inserts add structural integrity and enhance the windows ability to withstand wind pressure and other external forces, plus ensure maximum load-bearing capacity.
Glazing, the process of installing glass panes into the window frame, is a critical step in the construction of Thermotek windows.
Our window frames are designed to accommodate various glazing options, including double or triple glazing for enhanced thermal insulation and soundproofing.
Glazing beads, which hold the glass panes in place, are carefully positioned and secured within the frame.
Sealing and weatherproofing are essential aspects of uPVC window construction to ensure the window is airtight and watertight.
Specialised gaskets and seals are inserted between the glass and the frame, preventing the infiltration of air, water, and dust. Co-extruded gaskets in aluplast uPVC frames also ensure improved heat and sound insulation.
This not only enhances the energy efficiency of the window but also contributes to maintaining a comfortable indoor environment.
Various hardware components are integrated into uPVC windows to enable functionality. These include handles, hinges, locking mechanisms, and other accessories.
Thermoteks modern uPVC windows feature advanced locking systems that provide a high level of security. The hardware is installed with extreme precision to ensure smooth operation.
For example, the 85mm Lift & Slide window door systems from Thermotek are energy efficient and safe while also smoothly opening to the outside.
Even at its maximum size of 6.50m x 2.80m, the Lift & Slide door system can be opened and closed easily, ensuring a seamless transition to the outside thanks to very wide opening angles.
Its the perfect door for patios, balconies, and gardens, with a sash that slides parallel to the fixed pane of glass. Its a beautiful addition to spacious, flowing indoor/outdoor room designs.
Before Thermotek uPVC windows are ready for installation, they undergo rigorous quality control checks and testing.
These tests include assessments of air and water infiltration, structural integrity, and operational functionality. Only window and door systems that meet our strict quality standards are approved for distribution and installation.
Once the uPVC window and door systems have passed our quality checks, they undergo any necessary finishing touches, such as cleaning, polishing, and the application of protective coatings. These last steps ensure that the windows are beautifully finished and ready for installation in various architectural settings.
Crafted from aluplasts innovative 5-chamber uPVC profile, the Thermotek Boutique Series is visually elegant, with unparalleled adaptability for different styles of building projects.
Tailored and rigorously tested to stand the test of time in the challenging Australian climate, the Boutique Series windows and doors gracefully accommodate a wide spectrum of Green smart residential projects, spanning both ground-breaking new constructions and thoughtfully executed renovations.
The Boutique Series is available in a stylish range of Architectural and Woodgrain colour options that marry aesthetics with functionality.

More economically viable than thermally broken aluminium, the Boutique Series is also able to achieve the most favourable u-values for energy ratings.
Of course, the final step in the uPVC window construction process is the installation itself.
The dedicated team at Thermotek works with skilled design and construction professionals to ensure they carefully fit the windows into the designated openings, ensuring proper alignment, sealing, and secure fastening. Proper installation is crucial to optimise the windows performance and longevity.
As you can see, the construction of Thermoteks uPVC windows involves a careful, multi-step process that combines engineering precision, high-quality materials, and cutting-edge techniques.
From the fabrication of the uPVC frame to the installation of hardware and glazing, each step is integral to creating sustainable windows that offer durability, energy efficiency, and aesthetic appeal.

Windows
uPVC windows are a cost-effective, durable, and thermally efficient option for your home. When we start to uncover the benefits of uPVC window profile, its not hard to understand why its one of the most commonly used materials for windows in homes across the UK. Its worth understanding how the modern innovations of uPVC work and how they offer so many benefits to homeowners. Here, weve answered some of the more technical questions on uPVC windows to provide an insight into exactly what makes it such a tremendously popular material choice.
uPVC is an abbreviation for unplasticized polyvinyl chloride and it begins life as a plastic powder. It is then heated up and injected into a mould in order to form its shape as a strip of extremely long uPVC window profile. Once the uPVC has cooled, it is then cut and prepared to be assembled, along with other components, into what we recognise as a double or triple glazed window.
uPVC frames for double and triple glazed units work by being made up of multiple chambers of air within the frame. The use of these multiple chambers allows more heat to be trapped within the frame resulting in improved thermal efficiency for your home. Thermal efficiency describes how effective a particular material is as a heat insulator and is measured in the energy in Watts (W) lost per square meter of the material (m2). This provides us with a U-Value. The lower the U-value, the better, as this means less heat is passing through your window frames. This will help to keep your energy bills down as you will need to spend less on heating your home.
There are three main types of uPVC window profiles and they are described as ovolo, chamfered, and flush.
Ovolo window profiles are ideal for a timeless, traditional look with sculptured framing and rounded edges to the windows. Its a style that is popular for period style homes or those looking to put lots of character into their windows, such as properties with a modern country home aesthetic. Its a popular choice thanks to its decorative finish, creating an elegant curved shape with soft sightlines.
Chamfered window profiles, on the other hand, provide a sleek, classic, look for modern windows. This profile is defined by its neat, linear, appearance, creating a stylish feel wherever it is used. The flat edges have a more contemporary feel than ovolo designs. The chamfered designs still have a traditional and familiar look, just one that is more contemporary and less decorative than ovolo frames.
Flush casements windows are a timeless, elegant window solution, characterised by sleek window lines that fit flush into the window frame, unlike stormproof windows that overlap in the frame. When closed the window sash is level with the outer frame creating smooth and even external contours.
uPVC windows are low maintenance
One huge benefit of choosing uPVC profiles is that once youve had your windows installed, you wont have to worry about maintaining them. uPVC window profile is made from a non-corrosive material that only needs a little wipe down every now and again with a damp cloth to keep it looking as good as new. Timber windows, despite their natural beauty and charming aesthetic, are prone to rot and warping due to their cellular makeup and will need regular treating, painting, and cleaning. This is something you will never have to worry about again after investing in uPVC windows.
uPVC windows can be totally personalised to your taste
Our uPVC windows are available in a huge range of colours including the popular Chartwell Green, Dark Red, and Anthracite Grey. We also offer wood-effect finishes, such as Irish Oak, which resemble traditional timber windows. With this option, you dont have to compromise on aesthetics to obtain the modern innovations of uPVC. You can also choose the dual colour option to let the interior of your windows match your homes décor whilst the outside of the frame beautifully compliments your homes exterior.
uPVC windows are exceptionally energy efficient
Double or triple glazed uPVC windows will make a noticeable difference to the comfort of your home, reducing heat loss, and keeping it warmer and more insulated. In accordance with regulations, replacement windows must achieve an energy rating of C or above, and we are extremely proud to say that our windows offer up to an A+ energy rating.
We also inject the gap between our double or triple glazing panes with argon gas. Argon gas slows the transfer of heat through windows and doors. Since it is so viscous, it acts as a fantastic thermal barrier. Molecular movement is extremely restricted within the gas, so less heat is transferred and far less heat loss occurs.
uPVC windows are extremely secure
Our uPVC windows come with effective locks that will ensure your home is protected against intrusion. Internally beaded, our windows are resistant to forced entry and wont let you down. The beading refers to the part of the frame holding the glass in place and is usually a plastic strip at the edge of the glass which snaps securely into the recess. One of the biggest advantages of internal beading is that there is very little risk of it being removed from the outside. In order to remove the beading, an intruder would have to smash the glass and reach in, most likely disturbing you or possibly triggering an alarm in the process. You can rest assured that all of our windows have been rigorously tested to provide the best defense for your family.
Suitable for both modern and traditional homes, our uPVC windows are available in a range of styles including casement, tilt & turn, sash, and custom shaped.
You can have almost any glass design for your windows, including leaded or Georgian bars and stained glass to enhance a more heritage look. We also offer a large variety of customisable hardware so you can create the windows of your dreams. With multipoint locking systems, traditional handles, and sash horns available, its easier than ever to create your perfect windows. You can view all of our window glass, colour, and hardware options in our brochure.
