Construction & Specification

Engineered detail by detail

Door Jamb

Made of closed L-shaped steel profiles 2 mm thick and 100 mm wide, bonded to a wooden construction. The L-profile allows door sealing with a triple gasket between the jamb and the leaf.

Door Leaf

Built from 2 mm thick closed steel profiles connected to the wooden construction (leaf thickness 85 mm). The exterior face is clad with a 1.5 mm steel sheet.

Leaf Insulation

Stage 1: two-component foam expands between the closed steel profiles. Stage 2: three layers of 2 cm thermal rock-wool are applied to maintain excellent soundproofing and thermal properties.

Glazing

Triple-glazed unit of 4 or 6 mm glass, 54 mm total thickness. Supplied as standard with a clear or 40% brown tinted package. Decorative glass shapes and patterns are available from our carving catalogue.

Hinges & Anti-Lift Security

3 Italian hinges, 20 mm diameter, with journal-bearings prevent settlement and ensure effortless operation. 2 hinge guard stoppers block forced entry if the hinges are removed.

Cladding — UMIDAX

Moisture-resistant wood-fibre board fitted on all our standard exterior doors. Primed and painted in any RAL colour, with a wide variety of finishes to suit demanding requirements.

Cladding — Okoume

One of the highest-quality boards on the market, made from African Okoume peel (also used in shipbuilding) with mahogany intermediate layers. Finished with a four-colour polish so the armoured door looks like solid wood.

Locks

Supplied to the client's specification from premium manufacturers — MOTTURA, DORMA, EVVA and similar. To preserve maximum thermal performance we advise avoiding safe locks, as cold can bridge through the lock body.
