Smart Signature Aluminium Composite Doors

SMART SIGNATURE DOORS

Smart Signature Doors combine the strength of aluminium with the style and versatility of a premium composite door. Designed and manufactured in Britain, they deliver exceptional security, outstanding thermal performance and a flawless, long-lasting finish — making them an ideal choice for both traditional and contemporary homes.

Unrivalled Security

Every Smart Signature Door is fitted with a 3* Kitemarked Euro Cylinder and PAS 24 approved locking system. With multi-point locking, laminated glazing and a £4,000 security guarantee, your home is protected to the highest standard.

Powder Coated Finish

Finished in a durable marine-grade powder coat, Smart Signature Doors won’t warp, fade or crack. Unlike traditional composite doors, the frame and door are made from the same aluminium and colour matched perfectly.

Thermal Performance

With a 60mm thick aluminium composite door leaf, polyamide thermal barrier and twin weather seals, Signature Doors achieve U-values as low as 1.2 W/m²K. Designed to keep heat in and cold out, they help improve comfort and energy efficiency.

Designed for Every Style of Home

Aluna is a premium aluminium bifold door system engineered for strength, longevity and refined aesthetics. Designed with both installers and homeowners in mind, Aluna delivers exceptional reliability, smooth operation and precise detailing.

Manufactured using thermally broken aluminium profiles and tested to PAS24 security standards, Aluna bifold doors provide outstanding durability, thermal performance and peace of mind — making them ideal for modern extensions, renovations and architectural projects.

Built Stronger with Aluminium

Unlike traditional GRP composite doors, Smart Signature Doors feature a 1.5mm aluminium skin and a 60mm thick door leaf — 36% thicker than many standard composite doors. This provides superior strength, long-term stability and a visible deterrent to intruders.

Advanced Locking Options

Choose from slam lock or key-operated multipoint systems, including heritage slam lock options for traditional aesthetics. All locks are tested to rigorous standards, with cylinders tested against snap, drill, pick and bump attacks.

Extensive Colour & Hardware Choices

Select from Smart’s curated colour collections or almost any RAL colour, available in textured or matt finishes. You can choose matching or contrasting colours inside and out, along with a wide range of handles, knockers, letterplates and long pull handles in stainless steel, chrome or black finishes.

Virtually Maintenance Free

With no need for repainting or varnishing, Smart Signature Doors require only occasional cleaning to maintain their appearance. The durable aluminium construction ensures decades of reliable performance with minimal upkeep.
