High-Quality Aluminum French Doors
Aluminium French doors are increasingly popular in the UK due to their modern aesthetic, durability, and energy efficiency. They feature slim frames that allow for larger glass panels, maximizing natural light while maintaining structural integrity.
These doors come in various colours, including white, black, and anthracite grey and can be customized to fit specific needs. Security is enhanced with multi-point locking systems, making them a safe choice for homes. Additionally, they require minimal maintenance thanks to their powder-coated finishes, which are designed to last over 30 years.
Aluminium French doors significantly enhance a home’s aesthetic by providing a sophisticated and timeless look that complements various architectural styles. Their slim frames maximize glass area, allowing abundant natural light to flood interiors, creating a bright and inviting atmosphere.
These doors facilitate a seamless transition between indoor and outdoor spaces, blurring boundaries and expanding the perceived living area. Customisation options in colours and finishes further allow homeowners to tailor the doors to their personal taste, making them not just functional but also a stylish design statement in any home.
Features of our French aluminum doors
Aluminium French doors contribute to a home’s sustainability in several key ways:
- Durability: Their resistance to corrosion and weathering ensures a long lifespan, reducing the need for replacements and minimizing waste.
- Energy Efficiency: Equipped with thermal breaks, they effectively insulate against heat loss, leading to lower energy consumption for heating and cooling, which reduces carbon emissions.
- Recyclability: Aluminium is 100% recyclable without loss of quality, allowing for multiple lifecycles and significantly reducing landfill waste.
- Low Environmental Impact: The production of aluminium requires less energy compared to other materials, contributing to a smaller carbon footprint throughout its lifecycle.
Aluminium French doors are suitable for high-traffic areas due to their durability and low maintenance requirements. Made from strong aluminium, they can withstand heavy use without bending or wearing down, making them ideal for busy spaces. Additionally, they feature weatherproofing seals that enhance insulation and security, further supporting their functionality in high-traffic environments]. However, they can be susceptible to scratches and dents if not handled carefully. Overall, their robust construction and aesthetic appeal make them a practical choice for both interior and exterior applications.
How to maintain aluminium French doors?
To maintain aluminium French doors, follow these key steps:
- Regular Cleaning: Clean frames every 3-4 months using warm water and mild detergent with a soft cloth. In coastal or urban areas, monthly cleaning is advisable to remove corrosive residues.
- Inspect and Lubricate: Check moving parts annually for stiffness or noise and apply lubricant as needed.
- Check Seals and Hardware: Inspect seals for wear and hardware for damage annually to ensure proper insulation and security.
Avoid harsh chemicals to prevent damage to the finish.
Colour options
The most popular colours for aluminium French doors in the UK include:
- Black: A timeless choice, favoured for its versatility and modern appeal, particularly in urban settings.
- Anthracite Grey (RAL 7016): This colour has gained popularity for its contemporary look and ability to complement various architectural styles.
- White: A classic option that remains a favourite due to its clean and bright appearance.
- Grey: Often chosen for its neutral tone, fitting well with both traditional and modern homes.
Custom colours are also available, allowing for personalized aesthetics.
