Spitfire Doors says it has built its reputation on supplying premium front doors and firmly believes the S-500 Series represents one of the finest systems available on the market today.

The S-500 Series combines robust aluminium construction with advanced security features and outstanding thermal performance. The doors are precision engineered for structural integrity and each door is manufactured to deliver consistent quality that trade professionals can rely on.

With over 400 design options available and an impressive 95mm thick door sash, the range is said to offer considerable flexibility for installers and homeowners. One of the most popular designs currently features aluminium battens in a timber-effect finish, complemented by contrasting grey or black RAL colours.

Spitfire has recently expanded the range to include traditional glazed and unglazed door designs, giving installers more flexibility to match a wide variety of customer requirements. These styles can also include biometric access, a digital door viewer, and a door knocker, giving installers the opportunity to offer a wide range of options to customers.

At a time when energy costs remain a key concern for homeowners, Spitfire appreciates that specifying a thermally efficient front door is more important than ever. The S-500 Series achieves excellent U-values between 0.6–0.9 W/m²K, meeting Passive House standards and complying with current building regulations. All S-500 door models are tested to RC3 and PAS 24 standards, providing trade professionals with confidence in proven resistance to forced entry and ensuring compliant, reliable installations that meet UK security requirements.

A single door can be manufactured up to 1,400mm wide and 2,700mm high, creating a striking, oversized entrance that delivers a genuine sense of luxury to any property. In addition, optional biometric fingerprint access systems provide advanced keyless entry solutions.

Alongside product excellence, Spitfire Doors adds that it is committed to delivering a high standard of service to the trade. From initial enquiry through to installation and aftersales support, the team provides clear communication, dependable lead times, and responsive technical assistance.

This approach ensures installers can work with confidence, supported by expert guidance at every stage.
