Are aluminium front doors secure?

Extremely. Our Smart Systems 'Designer Doors' are tested to PAS24 standards and feature a 10-point locking mechanism, making them one of the most secure entrance options available for Winchester homes.

Are aluminium doors cold or prone to condensation?

Historically, yes, but not anymore. Modern KJM aluminium doors feature a 'polyamide thermal break'. This plastic barrier stops cold bridging, making them highly thermally efficient and condensation-resistant.

What is the difference between Bi-fold and Sliding doors?

Bi-folds concertina back to fully open up the wall, creating a seamless flow to the garden (about 90% opening). Sliding doors offer larger panes of glass for better views when closed, but usually only open 50% or 66% of the aperture.

What colours are available for aluminium doors?

We can powder coat your doors in almost any RAL colour. Anthracite Grey (RAL 7016) and Black are the most popular in Winchester for a modern look, but we also offer 'dual colour' options.

Smarts Designer Doors

The Modern Front Door

For a truly modern entrance, our Smart Designer Doors are the superior choice. Unlike composite doors which mimic timber, these celebrate the smooth, flawless finish of high-grade aluminium. They are incredibly robust, weighing less than timber but offering superior strength. Available in a vast range of designs—from traditional glazed styles to ultra-modern solid panels—they make a bold architectural statement while offering the durability to withstand decades of Hampshire weather without fading or warping.

A Warm Home (The "Cold Metal" Myth)

Thermal Efficiency

Historically, aluminium doors had a reputation for feeling cold and suffering from condensation. Modern engineering has solved this. All KJM aluminium doors feature a Polyamide Thermal Break—a reinforced plastic barrier inserted inside the aluminium profile that separates the cold outside metal from the warm inside metal. Combined with argon-filled double or triple glazing, our doors achieve low U-values that meet or exceed Building Regulations, ensuring your open-plan extension stays warm all year round.

Low Maintenance

For homeowners in Winchester, the low maintenance aspect of aluminium doors is a significant advantage. Aluminium is known for its durability and resilience, which translates into lower upkeep. These doors require just an occasional cleaning with soapy water to maintain their appearance and functionality. There’s no need for regular painting or staining, unlike timber alternatives. This ease of maintenance not only saves time and effort but also makes aluminium doors a cost effective option in the long term. Choose aluminium doors for hassle free upkeep and lasting performance.

Connecting Home & Garden

Visofold & Visoglide The primary reason Winchester homeowners choose aluminium for rear extensions is the strength-to-weight ratio. Aluminium is incredibly strong, allowing us to hold massive panes of glass with exceptionally narrow frames. Whether you choose the concertina style of Visofold Bi-folds or the panoramic views of Visoglide Sliding Doors, the result is a “glass wall” effect. This floods your kitchen or living space with natural light and provides uninterrupted views of your garden, perfect for modern living in areas like Badger Farm and Harestock.

Frequently Asked Questions

Extremely. Security is a primary feature of the Smart Systems 'Designer Door' range. They are tested to strict PAS24 standards and feature a high-security 10-point locking mechanism and adjustable hinges. This makes them one of the most secure entrance options available for Winchester homes, often exceeding the security levels of standard composite doors.

Historically, older aluminium frames were cold, but modern engineering has solved this. All KJM aluminium doors feature a 'polyamide thermal break'. This is a reinforced plastic barrier inserted inside the frame that stops the cold from bridging from the outside to the inside. Combined with argon-filled glazing, they are highly thermally efficient, resist condensation, and meet all current Building Regulations.

It depends on how you use your space. Bi-folds concertina back to fully open up the wall (about 90% opening), creating a seamless flow to the garden—ideal for summer entertaining. Sliding doors usually only open 50% or 66% of the aperture, but they offer much larger individual panes of glass. This gives you a better, uninterrupted view of your garden when the doors are closed (which is most of the year!).

We can powder coat your doors in almost any RAL colour. Anthracite Grey (RAL 7016) and Jet Black (RAL 9005) are currently the most popular choices in Winchester for a contemporary look. We also offer 'dual colour' options, allowing you to have a bold colour on the outside to match your windows, but white on the inside to keep your interior bright.
