Making environmentally responsible choices for property improvements is good for the planet – and also makes financial sense. At SGC Glass, we’re committed to providing sustainable glazing products that reduce energy consumption, minimise carbon footprints, and contribute to greener living while maintaining exceptional quality and performance.
Our range of eco-friendly glazing solutions helps property owners and developers in Essex and London achieve their sustainability goals without compromising on style or functionality. From energy-efficient windows to recyclable materials, we’re at the forefront of sustainable building design.
Why sustainable glazing products matter
The buildings we live and work in account for approximately 40% of the UK’s carbon emissions. Glazing plays a crucial role in thermal efficiency, affecting how much energy is required for heating and cooling spaces. By choosing sustainable glazing products, you can significantly reduce your property’s environmental impact while enjoying lower energy bills.
Sustainable glazing goes beyond just energy efficiency. It considers the entire lifecycle of products – from manufacture through to end of life – ensuring minimal environmental impact at every stage. At SGC Glass, our commitment to sustainability spans our entire operation, from sourcing recycled materials to reducing wastage during production.
Our range of sustainable glazing solutions
Energy-efficient double and triple glazing
Our high-performance double and triple glazing solutions provide exceptional thermal efficiency, dramatically reducing heat loss compared to single glazing. This means less energy needed for heating during colder months, resulting in lower carbon emissions and reduced energy bills.
Triple glazing offers even greater insulation, with U-values that significantly outperform standard options. For properties in exposed locations or for those aiming for the highest environmental standards in new build projects, triple glazing provides unmatched performance.
Sustainable aluminium windows and doors
Our aluminium windows come in a variety of styles including casement, tilt and turn, and sash options. These combine sleek aesthetics with impressive sustainability credentials. Unlike many building materials, aluminium can be recycled indefinitely without losing quality, making it a truly sustainable choice.
Our aluminium door range includes bi-folding doors, sliding doors, and residential doors, all featuring slim sightlines that maximise natural light – reducing the need for artificial lighting and further cutting energy use. These doors aren’t just stylish; they’re built with sustainability in mind.
Working with partners like Cortizo and Senior Architectural Systems, we offer aluminium products containing up to 100% recycled content. This significantly reduces the carbon footprint compared to using newly manufactured aluminium, as recycling aluminium requires just 5% of the energy used in primary production.
The longevity of aluminium further enhances its sustainability profile. Resistant to corrosion and requiring minimal maintenance, our aluminium frames last for decades, reducing the need for replacement and keeping materials out of landfill.
Energy-efficient uPVC options
For those seeking cost-effective sustainable solutions, our uPVC windows and doors offer excellent thermal efficiency thanks to multi-chambered profiles that provide superior insulation. Available in casement, tilt and turn, and sash styles, our uPVC windows deliver both functionality and impressive energy performance.
At SGC Glass, we source our uPVC products from industry leaders Rehau, renowned for their high-quality and environmentally responsible manufacturing. Rehau’s uPVC plastic can be recycled up to 10 times without significantly compromising its structural integrity, making it a strong choice for circular economy construction.
Our uPVC door collection includes French doors, patio doors, and stable doors – all designed to maximise thermal efficiency while requiring minimal maintenance throughout their lifespan. While uPVC isn’t infinitely recyclable like aluminium, modern advances such as Rehau’s sustainable production practices ensure these products make a meaningful contribution to greener building.
What makes composite doors different from standard options?
Composite doors represent an excellent balance between sustainability and performance, featuring a thermally-efficient solid timber core encased in GRP (Glass Reinforced Plastic). This combination delivers outstanding insulation properties with U-values as low as 1.0W/m²K, reducing heat loss by up to 40% compared to traditional door designs.
The environmental benefits of choosing SGC Glass
Reduced carbon footprint
By choosing our energy-efficient glazing, you’ll see a significant decrease in your property’s carbon emissions. The superior thermal performance means less energy used for heating, directly translating to a reduced carbon footprint.
Modern coatings on our glass panels further improve performance, reflecting heat back into rooms during winter while keeping solar gain manageable in summer. This balanced approach reduces reliance on both heating systems and air conditioning.
Sustainable manufacturing processes
Our commitment to environmental management is evident throughout our manufacturing process. We constantly work to reduce wastage, reuse materials where possible, and minimise our environmental impact.
Our factory employs efficient production methods that reduce energy consumption during manufacture. We also carefully manage waste materials, ensuring that glass and aluminium offcuts are recycled rather than sent to landfill.
Lifecycle considerations
We consider the entire lifecycle of our products, from sourcing raw materials to eventual disposal. Our sustainable glazing solutions are designed for longevity, reducing the frequency of replacement and associated environmental costs.
At end of life, our products can be largely recycled, particularly the aluminium components which can be reprocessed indefinitely. This closed-loop approach aligns with circular economy principles, minimising waste and conserving natural resources.
How sustainable glazing improves building performance
Improved thermal efficiency
By installing our sustainable glazing products, you’ll experience a noticeable improvement in your property’s thermal performance. Better insulation means spaces stay warmer in winter and cooler in summer, creating more comfortable environments year-round.
This improved thermal efficiency directly impacts energy consumption. Most properties see a significant decrease in heating requirements after upgrading to high-performance glazing, with corresponding reductions in energy bills and carbon emissions.
Reduced reliance on artificial lighting
Our glazing solutions optimise natural light transmission while managing solar gain, reducing the need for artificial lighting. This is particularly evident with our aluminium bi-folding and sliding doors, which feature slim sightlines to maximise glass area and light penetration.
The careful balance of light transmission and heat management is achieved through advanced coatings that allow visible light to pass through while blocking unwanted infrared radiation.
Certification and environmental product declarations
We understand the importance of verifiable sustainability credentials. That’s why our products come with comprehensive certification, allowing you to document the environmental performance of your glazing choices for planning requirements or sustainability assessments.
Many of our products have Environmental Product Declarations (EPDs), providing transparent, third-party verified information about their environmental impact. These declarations consider the entire lifecycle of products, from raw material extraction through to end of life.
Sustainable glazing for different property types
For period properties
Upgrading glazing in older buildings presents unique challenges. Our solutions include options specifically designed for conservation areas and listed buildings, providing improved thermal efficiency while respecting architectural heritage.
Our slim-profile aluminium windows can closely replicate traditional steel frames while offering significantly better thermal performance. Similarly, our sliding sash windows in both aluminium and uPVC can maintain period aesthetics without compromising on energy efficiency.
For new build developments
Developers working on new build projects can benefit from our comprehensive range of sustainable glazing products that meet and exceed building regulations. Our triple-glazed solutions help achieve desired energy ratings and contribute to overall sustainability goals.
By incorporating high-performance glazing from the design stage, developers can optimise building orientation and glazed areas to maximise natural light while maintaining excellent thermal performance, reducing lifetime energy consumption.
Choosing between materials: Sustainability considerations
When selecting window and door materials, sustainability is an important factor. Our aluminium products offer infinite recyclability and exceptional longevity, making them arguably the most sustainable choice for the long term.
Our uPVC options provide excellent thermal efficiency at a lower price point, with modern manufacturing using increasingly sustainable methods. For doors, composite options deliver outstanding thermal performance with their insulated core design.
Each material has its own sustainability profile, and our expert team can help you weigh these factors alongside aesthetic preferences and budget considerations to make the best choice for your specific project.
