Construction Ways of Prefabricated Houses / Manufacturing a Prefabricated House
unstoppable wall panel production, enables the company to stand in the advantageous position where large amounts of building materials are imported. Through massive import, better prices are achieved by enabling the company to buy the ‘expensive’ (for the Greek market) top quality building materials worldwide..
Materials:
Types and Advantages of Wall Panel Timber :
Swedish: Extremely compact
Pine: Better Moisture Resistance achieved
Dried: Long term furnaced timber (for weeks), by undergoing a natural deworming process and reaching the ideal humidity level of 15-16%, for house construction.
Ecological: Timber type which is free of chemical loads, also adopting the Swedish Timber Industry policy aiming at the absorption of carbon dioxide.
Planned: With perfectly flat surfaces which, in conjunction with the factory connection methods, achieves a perfect assembly of no margins at all, for all construction parts of the house.
C24 class: Of great mechanical strength, by displaying up to 80% more carrying capacity when compared to conventional timber.

The OSB Wall panel is :
Canadian from the LP factory by offering maximum mechanical strength and ultimate quality on an International Level. Being the first in worldwide production, this particular OSB is imported in Greece by Kofinas Company for your house construction..
Waterproof which acts like a moisture shield for the house.

The company innovates, since the technical defects due to the on-site construction of the masonry now belong to the distant past.
Our company constructs the masonry in the factory, using TORX screws, and always strictly following the construction steps:
1. Cornered
The Swedish beams that form the wooden frame are cut and set on alignment tables.
There, we achieve a perfect cornering and alignment of the wooden parts of every wall constructed.
2. Pressed
The wooden frame on which every wall is built, as well as the corners and the nodes, are pressed removing any gaps there might be.
This way, we have a perfect assembly of the wooden elements, awaiting for the next step, which is screwing them together.
3. Screwed
The wooden beams are screwed together using ΤΟRΧ screws.
The hem of the screw, combined with the absolute assembly that has already been achieved, “tie” the frame and form a very important factor of reinforcement for the masonry and for the construction in general, as proved by the experimental researches in the National Technical University of Athens.
4. Thermo – insulated
At the gaps of the wooden frame, we install ECOSE Technology mineral wool (A1 category – inflammable material).
The natural mineral wool offers exceptional thermo-insulation, sound insulation and resistance to fire. Knauf Insulation mineral wool with ECOSE Technology contains a formaldehyde-free conjoiner, which is produced by rapidly renewable organic materials and does not contain petrol-based chemicals.
5. Water insulated and shielded
The bottom of the wooden frame, which will be in contact with the concrete base, is waterproofed using an asphaltic membrane, thus minimizing any possibility of humidity penetration at the most critical part of the house – the base
The wall is then shielded on both sides using Canadian water resistant OSB, which is water proofing and sound proofing the wall even more. The ΟSB also multiplies the strength of the wall, having great mechanical strength and acting as a strut against distortion forces and as a shield as well against impacting or bending forces.
6. Tested
Each finished wall, before being stored, is carefully checked, and if no faults of any kind are found, it is stamped, certified its appropriateness and the high quality of company masonry!
7. Storage in the maturation area
Each finished wall, after the completion of the tests, is placed in the specially designed curing area (in the new factory of European specifications). Once completed, this stage is ready for installation!
The advantages of the factory production are of crucial importance.
It offers an absolute assembly of the parts of each wall (timber, OSB) and zero loosing through time is achieved.
The ready masonry parts act as monolithic bodies, as bearing walls, which respond to any type of oscillation. This way, we have a high seismic resistance and most of all, the robustness and quality of construction is ensured.
The factory masonry pieces are loaded on privately owned trucks and cranes, carried to the site and they are clamped on the concrete base.The assembling is done wall by wall in a minimum amount of time.
The installation on the concrete base is done with absolute accuracy using laser leveling equipment, which can corner and align the masonry on the horizontal and vertical levels at a maximum accuracy level.

The construction, loyal to the high quality, equips and completes each house using the most modern solutions, not only for the design but for the functionality as well.
Every material comes with a guarantee and an origin certification. As a matter of fact, upon delivery of a complete house, the customer receives a folio with all the guarantees and the certifications of the construction.
