Technology and features External doors

We make the door leaves exclusively from laminated solid timber, and the panels are made of engineered (multi-ply) board. This construction gives stability and resistance to the natural movement of the timber. We offer three leaf thicknesses, 68, 78 and 92 mm, all as standard. We choose the thickness to suit the thermal and acoustic requirements of the project and the character of the house.

Which thickness to choose

68 mm. The slimmest profile, with classic proportions. It works well in renovations and in projects of a traditional character, where faithfulness to historic proportions matters, and it also offers the highest sound insulation in this comparison.

78 mm. A profile with increased thermal insulation that keeps a balanced form. The most common choice for new houses, combining thermal and acoustic comfort with a timeless look.

92 mm. The widest profile, designed for energy-efficient and passive houses. The deep frame takes triple glazing and gives the lowest Uw value in our range, for investors who want the lowest possible heat loss.

Timber is the basic material of our windows and doors. We use carefully selected pine, larch, meranti and oak, matching the species to the construction, the character of the project and the visual effect expected.

The escutcheon protects the cylinder. With its steel reinforcement and no fixings on the outside, it is one of the most important components that make a break-in harder.

As standard we use the HOPPE London handle with a drill-resistant backplate, i.e. a steel reinforcement of the outer part of the backplate. The backplate has no fixings on the outside, which keeps access to the cylinder difficult.

It also matters that the cylinder sits as flush as possible with the backplate. The cylinder then cannot be pulled out from the outside and is harder to drill.

In the standard version, two layouts are available at no extra cost: a handle on both sides, or a handle inside and a fixed knob outside. The second layout means that the door can only be opened from the outside with a key.

As standard, the doors are fitted with two certified class C cylinders. Cylinders in this class have additional protection:

• hardened pins
• anti-drill protection
• a ring that protects the cylinder against being pulled out or snapped
• a lock-out triggered by an attempt to open it with a different key

Controlled key duplication adds further protection: an additional key for the Wilka cylinder can only be cut with the security card supplied with the cylinder.

Secure locking of the door the moment it is closed.

ABA Wiktorczyk external doors are fitted as standard with an automatic multipoint lock from FUHR. Once the door is pulled to, the additional locking points extend automatically – without having to turn the key.

Multipoint locking increases security and at the same time presses the leaf evenly against the outer frame. In this way it helps keep the door stable and airtight and limits the natural movement of the leaf.

Automatic locking

Once the door is closed, the mechanism automatically engages the additional locking points. The solution combines bolts with hooks which, once extended, are secured against being pushed back.

This means there is no need to remember to turn the key every time to engage the extra locking.

Security, airtightness and comfort

The automatic locking works every time the door is closed properly. Multipoint compression of the leaf supports its stability and helps keep the door airtight in everyday use.

We use Simonswerk BAKA 4010 FD recessed hinges with a load capacity of 160 kg on three hinges. They allow the leaf to be adjusted in three planes, so even a heavy door leaf can be set precisely. In outward-opening doors, we also fit the hinges with hinge-side security.

Unlike a screw-in hinge, a recessed hinge is fitted into pockets routed into the leaf and the frame. Its body stays concealed and there are no fixings on the outside. This gives a cleaner, more elegant look and makes tampering from the outside harder. In the FD version, the rebate seal runs uninterrupted through the hinge body, so no leakage gap forms at the hinges.

We finish the hinges with cover caps matched to the colour of the door, in antique gold, silver, black or white. All of these solutions come as standard.

In glazed models we use safe class P4 security glass as standard, in a clear version. To order, we can fit the door with any available glass, whether patterned, stained or crystal glass, chosen to suit the style of the interior and the facade. On request, we complete the door with any accessories available on the market.

We use a low, thermally broken threshold, designed for easy passage and for limiting heat loss at the bottom of the door. The low threshold makes everyday use easier, including for older people and children, and the thermal break limits the cold bridge at floor level.
