Flush, refined aesthetics

The exterior of your brand new Spitfire S-100 entrance door is designed with flush lines, so there is no projecting frame beyond the door leaf. This gives a clean, contemporary look that pairs beautifully with modern architecture or traditional facades.

The door and frame are powder coated using marine-grade coatings that resist fading, chalking and corrosion even in harsh climates. This ensures your door looks good year after year with minimal maintenance.

Security is integral to the S-100 design. All glazing is laminated and tested to resist forced entry. The door’s locking hardware is a multi-point system with hook locks and deadlock mechanisms. In our Spitfire range, we exceed PAS24 and achieve RC2 / RC3 classification (depending on configuration) under IFT Rosenheim standards.

We back every Spitfire door we install with a robust guarantee (typically 10 years or more, depending on the series). After installation, we provide support and servicing to ensure that your new entrance door continues to perform as expected.

Our Installation Process

As with our aluminium window installations, we apply the same rigorous approach when fitting your S-100 entrance door:

1. Free site survey & consultation
We visit your property to take accurate measurements, understand structural constraints, and advise you on design choices and technical feasibility.

2. Bespoke design & ordering
Based on your chosen style, colour, and glazing options, we work closely with Spitfire to manufacture your door to exact measurements. Throughout the process, we’ll keep you fully informed and updated every step of the way.

3. Professional, certified installation
Our trained installers fit the door with precision, ensuring alignment, sealing, and mechanical tolerances meet or exceed standards.

4. Commissioning & handover
We thoroughly check the locks, hinges, and weather seals to make sure your door performs perfectly. Once everything’s ready, we’ll show you how to use and look after it with ease.

5. Aftercare & guarantee
In the rare event that any issues arise, we’re here to help. Your door is fully covered by our warranty, and we’re always available for servicing or adjustments whenever you need us.
