The construction of factory-made wooden elements and their use with other structural materials is widespread throughout the Nordic countries. Wooden elements accelerate the construction process and thus reduce the cost of construction.

We offer the facade elements of the outer wall according to the client’s project in maximum readiness.

Timbeco’s partners are contractors and real estate developers of different sizes who value our expertise and know-how in the design, manufacture and construction of wooden elements. The high quality of production, and the financial savings are the main arguments that are increasingly favouring the use of wooden elements. The construction of the elements significantly save time for construction and several different costs for the object, such as the rental of scaffolding or roof tiles or the management of a construction project.

Prefab wooden elements are used with various designs

When designing a building, the choices made depend on what kind of house it is. Of course, the security and cost of construction are part of the decision-making criteria. Timbeco engineers have long experience, we can develop and design optimal and cost-effective timber element construction. As a rule, what is involved in the design process of a wood element manufacturer at an earlier stage, the better is the result.

ENERGY EFFICIENCY OF A PREFAB HOUSE

By energy efficiency, we mean the controlled movement of air in the construction. Achieving control over the movement of air is the main goal of today`s energy efficient construction. Uncontrolled movement of air in the construction also causes movement of moisture. In addition to extreme heat loss, this also causes the wall construction to get wet and this results in damage: e.g. mould, rot, etc. Mould spores suspended in room air can pose a serious health problem. In order to avoid damage caused by moisture, vapour and air barriers with varying moisture resistance must be used.

The drying capacity of the construction must always exceed the estimated moisture load. Simple vapour barriers are not allowed to be used in modern constructions; certified vapour and air barrier systems must be used instead.

We use special tapes for windows and doors and corner joints, and natural latex based adhesive for fixing the edges of air and vapour barrier paper to concrete and wood..

We use certified air and vapour barrier systems. The certificate confirms the purpose of the system and its resistance to ageing. This is necessary because the energy-performance label is issued for a ten year period. After ten years, an energy audit is performed again and by then, the elimination of defects caused by the use of incorrect materials would be very difficult and expensive

Quality installation of the air and vapour barrier system according to the instructions is very important for ensuring that the house is air tight. It is impossible to make the house air tight without high quality and careful installation.

We check the energy efficiency of a prefabricated house that is manufactured and built by us with certified pressure tests. In order to avoid defects caused by the movement of air it is necessary to perform an air-tightness test (Blower-Door pressure test) during construction, after the installation of air and vapour barrier and before the installation of internal cladding. Prior to the installation of internal cladding and internal finishing works, it is still possible to fix the air leaks that were detected during the pressure test.

The pressure test is conducted using the pressure difference method (Blower-Door), which means that negative air pressure or overpressure of 50 Pa is created in the building using a fan installed in the door or window opening. Then the number of times the air in the entire room changes within one hour (1/h) is measured. The allowed air change rate is 3/h; 0.6/h in case of passive houses . Unlike a thermal camera test, the Blower-Door test can be conducted all year round.
