Environmentally friendly wood fiber insulation provides protection against the cold, contributes to the moisture-technical performance of structures and increases the energy efficiency of buildings.

Wood fiber materials have the highest heat capacity of all insulation materials on sale. This makes them the best protection against the summer heat.

Wood fiber insulation is rainproof but at the same time has good water vapor permeability. They have good fire test properties and excellent sound insulation.

The materials are easy to handle and install. The solutions are simple and long-lasting.

The wood is broken into fibers and the fibers are made into bulk wool that can be installed with a blower, flexible insulation mats and also hard insulation boards. STEICO products are covered by the PEFC certificate.

STEICO insulation materials make a significant contribution to ensuring a uniform room climate both in summer and winter.

Pro Clima

A weatherproof vapor and air barrier system is an important part of the structure.

Air tightness has a significant impact on our indoor comfort, activity and performance. Although comfort cannot be objectively measured because people perceive the surrounding environment differently, it is possible to create an indoor climate that meets the comfort of most people.

When preventing structural damage to the structure, it is not the vapor barrier properties that are decisive, but the amount of drying reserves of the structure is important.

The air barrier layer prevents air movement in the structure.

Pro Clima offers compatible, long-lasting complete system solutions for safe and practical airtightness, each consisting of vapor and air barrier fabric, joint adhesive, construction tape, as well as cuffs and detailed special solutions.

MHM® nail laminated massive wood

Nail laminated massive wood (MHM) is made from planks milled into a groove. Cross joining with aluminum nails creates a very strong and stable structure.

The “channels” in MHM help to improve heat retention, significantly reduce the risks of moisture damage and increase the soundproofing of the structure

The massive wooden structure perfectly regulates humidity and prevents electromagnetic radiation.

Only technically dried wood is used for production, in order to protect wooden structures from wood pests.

Only natural materials are used exclusively for the production of Fermacelli gypsum fiber boards, which is one of the factors in ensuring a healthy room climate. The plate is resistant to mechanical shocks, fireproof (A2 EN 13501-1 st. from 30 min.), sound-insulating, moisture-proof, bearing circle and stiffness plate. They ensure the stability and safety of a high-quality wooden building. Fermacell gypsum fiber board allows you to do everything necessary in a building from the basement to the attic, using it in the construction of ceilings, walls and floors, in a space-saving manner.

Gypsum fiberboard contains gypsum and waste paper. These two natural materials are mixed into a uniform mixture and water is added (without binders), a stable and odorless building board is pressed under high pressure. It is dried and cut to the required size.

Clay and lime products

100% natural and recyclable products. There are many soft and natural shades and finishing options that can be used to create very exciting and personal solutions for all rooms – including laundry rooms. In addition, these products perfectly regulate air humidity, are suitable for allergy sufferers, prevent electromagnetic radiation and only help to neutralize unpleasant odors.

Clay and lime products are sustainable building materials with a small ecological footprint.

Clay products are an ideal choice for finishing dry interior spaces. Clay is the binder with the lowest energy consumption. Clay has an excellent ability to maintain the humidity of the room between 40-60%, which is the best for the human body.

Lime products are the best choice for damp rooms and facades. Lime plasters are well suited for public spaces and surfaces with greater load. Smooth lime-based finishes are the first choice in shower corners or when you want to wash the walls.

Properly selected materials make the MHM house complete.

What is MHM Massiv-Holz Mauer?

What is MHM Massiv-Holz Mauer?

Building with wood is good for both people and the environment.

MHM® - Massiv-Holz-Mauer® - massive wood

Massiv-Holz-Mauer “MHM” or cross-layered timber is a solid, dry construction material made of massive solid wood.

Nail-laminated timber is a 100% film, adhesive, and chemical-free wall construction, which means that natural heat exchange and moisture movement are not hindered. The natural structure of wood absorbs and releases moisture, thereby regulating humidity. This creates a self-regulating indoor climate, resulting in a truly comfortable and healthy living environment.


Nail-laminated timber Massiv-Holz-Mauer – MHM is produced from high-quality softwood boards.

Thanks to the optimal technical drying of the wood, with a residual moisture content of approximately 15%, untreated boards exhibit excellent dimensional stability and resistance to pests.

We use both FSC® and PEFC certified raw materials.

Production preparation

Massiv-Holz-Mauer cross-nailed wood panels are made from ribbed wood layers. The purpose of the grooves is to create air cushions and the capacity of the air there for better heat and sound resistance of the structure.

When the surface of untreated boards is grooved, air cushions of the finished wall are created, which improve the heat retention of the wall by about 20% compared to ordinary wood. This allows the homeowner to save 20% on wood and insulation material, which is economically beneficial.

The width of each table is between 140 – 260mm and the thickness is 24mm.


Production - the first stage

The cross-nailed studded wood elements are produced on the “wall master” production line specially developed for this purpose.

All the layers of the board are placed crosswise. Vertical boards are load-bearing, horizontal boards are binding. The panel is very dimensionally stable, but it plays very minimally. With the measuring instruments used on the object, it is not possible to measure its shrinkage and expansion due to humidity, because it is minimal.

In order to connect the boards together, we use aluminum nails. The use of aluminum nails gives the opportunity to process panels on wood processing equipment.

On the production line, ready-made elements are made, the size of which can be a minimum of 2m x 2m and a maximum of 3.25m x 6m. Wall thicknesses are 11.5 cm to 34 cm, depending on the target. Or 5 to 15 layers of wood.

Production - the second stage

The necessary door and window openings are made for each semi-finished wall element in a CNC processing center. All the holes, grooves and cutouts necessary for heating, sanitary equipment, electrical plugs and other devices are made with the help of a computer in the MHM wall with high precision.

Of course, it is also very easy to do additional milling work later.

Watch the video introducing Massiv-Holz-Mauer - MHM solid wood:

Transverse fastening with special aluminum nails creates very strong and stable elements, offering an alternative to concrete and stone structures.

Thanks to the grooved layers of wood, sound waves are refracted in the air ducts.

In addition, the grooves help with any excess moisture that can penetrate the wall, for example, in the event of a water disaster. Thanks to the grooves, moisture can quickly get out of the structure again and the drying process takes place quickly, which significantly reduces the risk of mold.

The cross-nailed massive wood construction impresses with its very good sound insulation characteristics, regardless of whether it is noise coming from inside or outside. Good sound insulation characteristics result from the large base mass and layered structure of MHM®. Residents appreciate the excellent sound insulation properties of the MHM® wall.

For various solutions, we offer specially developed and tested wall constructions that allow creating a combination of noise and fire protection. For example, would you like a noise-reducing partition wall between you and the children’s bedroom?

We have the right noise protection solution for every situation, e.g. the high requirements of hotels or partitions in apartments.
