Technology

Thanks to the modern technologies, nowadays, the construction of timber frame houses is developing rapidly, therefore, the building can be constructed in a much shorter time than the traditional concrete buildings. The technologies which are used today, in terms of speed and durability, allow timber frame buildings to compete with concrete and brick buildings. The timber frame panels used in building construction are relatively lightweight, so there is no need to form a solid foundation, and this reduces the global cost of the building. In our production, we use two technologies for producing wall modules. This is CROSS-LAMINATED TIMBER (CLT) technology and PREFABRICATED WOOD FRAME technology. We present below all the key information about each of the technologies.

CROSS-LAMINATED TIMBER (CLT)

CLT is a wood panel product made from gluing layers of solid-sawn lumber together. Each layer of boards is usually oriented vertical to adjacent layers and glued on the wide faces of each board, usually in a symmetric way so that the outer layers have the same orientation. Regular timber is an anisotropic material, meaning that the physical features change depending on the direction at which the force is applied. By gluing layers of wood at right angles, the panel is able to achieve better structural rigidity in both directions. It is comparable to plywood but with characteristically thicker laminations.

CLT HAS SOME ADVANTAGES
AS A BUILDING MATERIAL,
INCLUDING:

Design flexibility – CLT has many applications. It can be used in walls, roofs or ceilings. The thickness of the panels can easily be increased by adding more layers and the length of the panels can be increased by joining panels together.
Eco-friendly – CLT is a renewable, green and sustainable materialsince it is made out of wood and does not require the burning of fossil fuels during production.
Prefabrication – Floors or walls made from CLT can be fully manufactured before reaching the job site, which decreases lead times and could potentially lower overall construction costs. Thermal insulation – Being made out of multiple layers of wood, the thermal insulation of CLT can be high depending on the thickness of the panel. CLT is a relatively light building material – Foundations do not need to be as large and the machinery required on-site are smaller than those needed to lift heavier buildings materials.

PRODUCTION

The production process includes the following phases:
-Analysis of the construction project.
-Adaptation of the project to the CLT solid wood system.
-Preparation of production documentation
-Production of CLT panels
-Checking the execution of the elements
-Specification of the assembly procedure
-Protection of panels against atmospheric conditions during transport.
-Loading
-Transport of elements to the place of assembly. Buildings are erected in approximetly 1 week from delivery on the site.

Prefabricated homes, often referred to as prefab homes or simply prefabs, are specialist dwelling types of prefabricated buildings which are manufactured off-site in advance, usually in standard sections that can be easily shipped and assembled.

PREFABRICATION

The prefabricated elements of the house (walls, ceilings, roof truss) are made in the production hall. This solution is better than traditional construction because:

Definitely speeds up the construction of the house
The production process is not influenced by weather factors (rain, snow)
Elements of the house are made very carefully, which facilitates its further finishing.

Production of prefabricated medium-sized houses takes from a few to several days. Their assembly on the construction site is only a dozen hours of work. That is why the technology of wooden prefabricated houses is gaining more and more supporters.

WALLS

The wall structure is pressed on a pneumatic table, which gives it extraordinary compactness and rigidity. The prepared skeleton is stiffened with structural plates on both sides. The interior of the wall is filled with a layer of mineral wool thermal insulation. Pipe pipes for electrical installation and places for water and sewage installations are being prepared and central heating.
Keeping the principles of warm assembly and using expansion seals and special flanges, walls and external window sills are installed in the walls. A layer of thermal insulation is mounted on the external walls of the building (e.g. polystyrene together with glue and mesh).

FLOORS

Wooden beams are cut in accordance with workshop drawings and bolted together they are in such a way as to form ceiling panels.
The MFP or OSB building board is screwed to the wooden frame prepared in this way. The ceilings are then filled with mineral wool sound insulation. A wooden grate for GKF boards is nailed to the ceiling structure.

ROOF

Wooden beams for the roof structure are cut in accordance with the workshop drawings. Visible roof structure elements are ground and painted in the production hall. The roof structure is mounted directly on the construction site.
