The Spitfire S-100 Series Doors deliver excellent security and certificated Passive House thermal efficiency. By fusing world class engineering with the finest materials, these bespoke alu-steel entrance doors can be made in sizes larger and wider than composite front doors.

With an incredibly low U-Value of just 0.77 W/m²K for solid designs and 0.88 W/m²K for glazed options, the S-100 Series can handle the toughest weather conditions whilst meeting Passive House standards.

40 designs 18 finishes

The S-100 Series combines the strength and stability of a steel door leaf with the reliability of an aluminium frame, with Solar Shield technology finishes. This high-performance surface treatment reflects infrared radiation to prevent heat build-up and preserve the stability of the door. Spitfire offers 18 finishes, including dual colour options.

Spitfire adds that it is aware that homeowners today are on the lookout for front doors that offer both premium quality and robust security and is confident that the S-100 meets the demand.

All S-100 models meet RC2 and PAS 24 security standards, providing trade partners with a high quality alu-steel door, which meets regulatory requirements on new builds and renovations.

For years, composite doors have been the go-to for budget conscious homeowners. But now, with Spitfire’s alu-steel front doors starting at just £1,150 + VAT for solid designs and £1,250 + VAT for glazed options, Spitfire says that the S-100 allows aluminium to outshine contemporary or traditional style composites for an equivalent price.

To help customers get started, Spitfire Doors offers a white label digital copy of the S-100 Series brochure which it can customise with a company logo.
