Leaf sheathing is made of galvanized steel laminated with PVC of the highest quality – the same that is used for the production of PVC windows and garage doors.
Galvanized steel is an extremely rigid and hard material, which ensures adequate resistance to dents or deformations.
The laminate is very durable and has a high resistance to scratches and UV radiation. No maintenance required. A special coating with low adhesion makes the door very easy to clean with the simplest agents – water and washing-up liquid.

Wood provides excellent thermal insulation and is a very good construction material. Unfortunately, it is not resistant to weather conditions and requires maintenance. Veneered galvanized steel is weather-resistant. It is very rigid, resistant and durable. The WOOD-STEEL door frame combines the advantages of galvanized steel and wood, while eliminating their disadvantages.

A burglar-proof pin with a diameter of 12 mm is mounted on the door leaf at each of the three hinges. After closing the leaf, the bolt goes to a special hitch located on the frame. This solution very effectively protects the door against an attempt to lift the leaf from the side of the hinges.

An ADDITIONAL UPPER LOCK with three 12mm diameter bolts is placed in the upper part of the leaf. This lock effectively protects against attempts to break down the door and enables the use of a convenient insert which is located out of reach of small children and has a knob that enables daytime locking without the use of a key.

A MASTER LOCK with three 12mm diameter bolts placed in the central part of the leaf. Effectively protects against attempts to break down the door with a crowbar in the area of the handle – the most common way of forced entry.

3D hinges are adjustable in three planes – you can move the leaf to the right or left, up or down, and slide it towards or away from the frame. This makes it possible to easily and efficiently eliminate leaks without having to remove the leaf.

In Arktic doors, the sealed unit consists of 4 glass panes with a thickness of 4mm each, making it a three-chamber unit that provides the highest thermal insulation.

In the case of Arktic doors with PVC glazing beads, the sealed unit consists of 3 panes (TRADITIONAL models).
Depending on the selected model, the individual panes in the package are decorated. They can be reflective, mirror, sandblasted, painted, stained-glass, etc.

The leaf is filled with very dense PUR foam using injection technology. This is the most technically advanced solution. It ensures the best parameters and properties of the door.

A thermally efficient threshold protects the threshold zone of the door against freezing, ensures adequate stiffness and tightness. The materials used are scratch-resistant. One great advantage of this solution is its unique aesthetics.

ALU MARTOM door frame was designed especially for MARTOM doors. It combines the highest level of technical parameters with modern, simple design.

Excellent thermal transmittance compared to other ALU solutions has been achieved thanks to the width of the profile, reaching 90 mm. An additional thermal insert made of graphite EPS has been introduced into the so-called „warm chamber” in the profile.

ALU MARTOM door frame features enlarged dimensions. Thanks to this, the hinges are located at a distance from the edge of the profile, which makes plasterwork and door adjustment very easy. Because aluminium is an expensive material, companies often look for savings by reducing the size of their profiles. When comparing individual solutions, it is worth noting the achieved thermal insulation coefficient and the dimensions of the frame profile.

ALU MARTOM door frame has a simple, modern shape. It is veneered in the same way as the door leaves. Thanks to its robust construction, it fits well with the wide leaves in the Passive door ensuring the right proportions.

ROTO QB lock:
• exceptional functionality + safety only in the MARTOM assortment
• three locks operated with one key movement
• fourth lock as standard
• unique two-stage pressure mechanism
• double tightness
• maximum safety
• german quality and precision

The ENEO automatic multipoint lock is equipped with a drive unit (special mechanism with an electric motor). After each closing of the leaf, the reed switches located on the leaf and door frame are shorted, which automatically locks all three locks. When the door leaf is closed, it is always locked without any additional operations.

The lock is included in the set with the grip from the outside and the handle from the inside. MARTOM offers two solutions for automatic door opening from the outside:

• Fingerprint reader — when an authorized person puts a finger to the reader, the door is automatically opened.
• Code keypad integrated with the smartphone, Bluetooth & Code system — opens when a 4- to 8-digit code is entered. After downloading the special application, the smartphone connects to the keyboard via Bluetooth when approaching the door. To unlock the lock, simply press the OK button.

Being inside the room, the door unlock automatically when the handle is pressed. In the event of a power failure, it is always possible to open and close the door using a conventional key.
This solution, in addition to great comfort, significantly improves safety. We are sure that no unauthorized person will enter the house without our knowledge.

Comparison of WOOD-STEEL and ALU door frames
From a technical point of view, WOOD-STEEL and ALU door frames are very similar. Mechanical properties such as strength, stiffness and durability are comparable. WOOD-STEEL door frame features a slightly better thermal insulation coefficient, while ALU door frame is lighter. Thus, no solution has a significant technical advantage. Both types of door frames will function perfectly for many years. Therefore, the decision may be conditioned by factors of cost, aesthetics or personal attitude of the Client towards a given type of material.
There is a certain range of offers where the choice of ALU door frames is recommended. The recommendation is based on aesthetic reasons. It is a case of combining doors with door lights. The combination of an aluminium frame with aluminium door light is very aesthetic. This is due to the fact that the two corner elements are connected at an angle of 45 degrees. In addition, the shape tolerance of the aluminium profiles is rigorously maintained and the joint is therefore perfectly flush with the entire length of the profile.
