For sustainable builders, selecting the right materials is vital, not only for their environmental impact but also for their performance, durability, and lifecycle costs and impact.
To get it right, sustainable builders need to adopt a holistic approach, considering the embodied carbon, longevity, and overall lifecycle of materials. Among the various options available, uPVC (unplasticised polyvinyl chloride) has emerged as a leading choice, alongside traditional materials like timber and aluminium.
Incorporating uPVC into crucial features like window frames can significantly optimise energy efficiency and thermal comfort for inhabitants. Its durability is also a key component of its sustainability. Thermotek uPVC window and door systems are sustainably manufactured in Melbourne and constructed to withstand the toughest Australian conditions.
Let’s take a closer look at what sustainable builders are looking for when it comes to materials, plus how uPVC fits the brief.
The Importance of Material Selection in Sustainable Building
When sustainable builders evaluate materials, they don’t just focus on the immediate benefits; they consider the long-term implications for the environment, the building’s occupants, and the project’s overall success. Key factors for consideration include:
- Embodied Carbon: Embodied carbon refers to the carbon dioxide (CO2) emissions associated with the production, transportation, and installation of building materials. Sustainable builders aim to minimise embodied carbon by selecting materials that require less energy to produce and have a longer lifespan, thereby reducing the need for replacements.
- Durability: Materials that can withstand the test of time without significant maintenance or replacement are essential in sustainable construction. Durability reduces the frequency of repairs and replacements, conserving resources and minimising waste.
- Lifecycle: The lifecycle of a material encompasses its entire journey, from raw material extraction to production, use, maintenance, and eventual disposal or recycling. Sustainable builders focus on materials with a low environmental impact throughout their lifecycle, ensuring they contribute to a greener future.
Why Sustainable Builders Are Choosing uPVC Windows
uPVC windows have gained considerable traction in the sustainable building industry due to their blend of performance, cost-effectiveness, and environmental benefits.
Compared to more traditional materials like timber and aluminium, uPVC offers several distinct advantages that make it a top choice for sustainable builders.
Low Embodied Carbon
uPVC has the unique quality of being able to be recycled multiple times without significant degradation of quality, which means that the same material can be used in new windows or other products, dramatically lowering the carbon footprint of the production process.
Embodied carbon is largely influenced by the energy-intensive processes required to extract raw materials, manufacture products, and dispose of them at the end of their lifecycle. When uPVC is recycled, it reduces the demand for new raw materials and the energy associated with their extraction and processing.
Recycling uPVC (unplasticised polyvinyl chloride) plays a significant role in reducing embodied carbon, making Thermotek uPVC windows an even more sustainable choice. It cuts down on the manufacturing of new materials and reduces waste that would otherwise end up in landfills, where it could release carbon emissions over time.
Excellent Insulation for Low Utility Bills
Sustainability also incorporates facets such as comfort and affordability. Sustainable builders love uPVC windows for their long-term payoff.
Thermotek uPVC windows, for example, are engineered to deliver exceptional thermal efficiency, which translates to enhanced comfort and lower energy bills for homeowners.
uPVC is a low conductor of heat, ensuring excellent insulation and reducing the need for extensive heating or cooling systems. When combined with double or triple glazing such as in Thermotek windows, it can significantly enhance energy efficiency.
The multi-layered glazing system, consisting of two or three panes of glass separated by insulating gas-filled spaces, reduces heat transfer between the interior and exterior of a building.This minimises the amount of warm air escaping in winter and prevents excessive heat from entering during summer, maintaining a comfortable and consistent indoor temperature.
uPVC, being a low-conductivity material, further contributes to this insulation by preventing thermal bridging, which is the process where heat passes through the window frames. This differentiates it from aluminium, which needs to be thermally broken.
As a result, buildings with uPVC double or triple-glazed windows require less energy for heating and cooling, leading to lower energy bills and reduced carbon emissions. This improved energy efficiency not only enhances comfort but also supports sustainability goals by reducing the building’s overall environmental impact.
Low Maintenance and Durability
Maintenance is a significant consideration for sustainable builders, as frequent upkeep can increase the environmental impact of a building over time.
Timber windows, while aesthetically pleasing, require regular sanding, varnishing, and painting to prevent issues like rotting, termite infestations, and scratches. These maintenance activities not only add to the cost but also involve the use of additional chemicals and materials, which can harm the environment.
Aluminium windows, while more durable than timber, still require attention to prevent corrosion and maintain their appearance. In contrast, uPVC windows are virtually maintenance-free. A simple wipe with a damp cloth is all that’s needed to keep them looking new, making them a convenient and sustainable choice for builders and homeowners alike.
Thermotek uPVC window products such as the Sliding Systems are specifically designed to withstand the harsh Australian climate, offering durability and resistance to extreme weather conditions.
In fact, all Thermotek uPVC window and door systems are engineered to maintain their structural integrity and aesthetic appeal even in the face of extreme weather conditions. Their resistance to corrosion, rotting, and UV damage ensures that they maintain their appearance and functionality for decades, making them an ideal choice for long-term sustainability.
Energy Efficiency
Energy efficiency is a cornerstone of sustainable building practices, and this is where uPVC windows really excel.
Their superior thermal insulation properties help maintain a comfortable indoor environment, reducing the need for additional heating or cooling. This not only lowers energy bills but also aligns with efforts to reduce carbon emissions and combat climate change.
Thermotek uPVC windows are designed with energy efficiency in mind, featuring multi-chamber profiles and advanced sealing technology to minimise heat loss. These features result in significant energy savings and a more comfortable living environment, making them an ideal choice for builders committed to sustainability. The energy efficiency of uPVC windows also contributes to achieving higher energy ratings for buildings, which is increasingly important in meeting stringent building codes and regulations in Australia.
For example, a 7-star NatHERS energy efficiency rating is now required as part of the National Construction Code (NCC).
By choosing uPVC windows, builders can meet compliance requirements, reduce the overall environmental impact of their projects and support the growing demand for sustainable building materials.
Choosing a Stylish uPVC Finish
When it comes to aesthetics, uPVC windows offer a wide range of finishes and colours, allowing builders to customise the look to suit various architectural styles.
This flexibility is particularly important for sustainable builders who aim to create beautiful, functional, and environmentally responsible buildings.
Thermotek’s Boutique Series, for instance, offers a variety of architectural design finishes that can be tailored to match the style of any home, whether traditional or contemporary. Their versatility makes them a stylish choice for builders who prioritise both design and sustainability.
