Modern Timber Doors. S-400 The Natural Choice

For those who love the sheer beauty of natural materials (and who doesn’t?), Spitfire’s new S-400 Modern Timber doors range really is the obvious choice. The outer faces of each door are solidly constructed from West Canadian red cedar (‘thuja plicata’), a species justly renowned for the exceptional beauty of its grain, its rarity and great durability.

The beautiful fine grain also enables a superbly smooth finish, stained to bring out the natural colour of the wood in all its glory. The warm glow of the timber is superbly offset by the cool modernity of stainless steel hardware and subtly elegant aesthetic touches such as organic glass insets, wholly exclusive to Spitfire Doors. While a bespoke care and maintenance kit is also available for easy care.

The Beauty Of High Performance

Secure and solid, our standard door leaf is a substantial 94mm thick, constructed of solid red cedar outer faces, fibre-board for acoustic insulation and high insulation foam for thermal efficiency, with a thermally broken low threshold @ 20mm high.

Looks Great, Keeps You Safe

With its security barrel and five-key multipoint locks, the S-400 range doesn’t just look great; it helps keep you safe too.

There’s a wide choice of state-of-the-art, discreetly integrated security options for biometric and keyless entry (simply waft your hand over the sensor to open), automatic key fob opening or fingerprint recognition (capable of storing up to 100 impressions) and, of course, a physical key for manual override.

Biometric and Keyless Entry Options

Our standard lock is 8-point hook locking with a keywind cylinder. Spitfire S-400 Series entrance doors can also be equipped with discreetly integrated technology which allows you to lock and unlock your door without the use of a key.

Exceptional Performance

Our unique construction method provides you with a door that is not only incredibly stable but also offers remarkable thermal qualities and performance with a U value of 0.77 W/m²K, lower even than the most demanding Passiv Haus standards!

Not only that but our S-400 range is focused on minimal environmental impact with it’s A rating for the managements of those precious natural resources. All of which means our unique S-400 doors will shield you from high running costs while protecting the environment both inside and outside of your beautiful new front door!
