Production stages

The EcoHouse Group glulam beam is made of perfect high-quality pine. The raw materials pass all stages of transformation to a multilayered glued beam at our plant.

1. Material selection

The production cycle begins with sorting and selection of the board corresponding to the sizes and meeting rigid requirements of quality.

The sorted board goes to a drying complex.

2. Modern drying technologies

Our drying complex is a completely automated system of the Italian production Copcal, that uses the latest technologies of drying. The system consists of four 120 m3 cameras in size each (the sizes correspond to the board volume).

The board using for moulded products production is dried to the 14% (+-2%) humidity level. Production of a glued beam requires a board of humidity level not higher than 12%. In takes 8-10 days of the average drying process.

After that packages of a board are moved to a stabilization zone where they are maintained about a week to remove internal stress out of a material.

3.Sorting

After drying the board passes sorting process again. At that stage it is also sorted to raw materials for the glued beam, and to the board for the moulded products.

4. Moulded products

For the manufacturing of moulded products the board runs through the machines that form the product profile. If needed the board runs through the modern high efficiency four-sided planning and moulding DEDRA PLUS 6/S machine (Italy) in which the accurate geometrical length sizes are set. After that the board is packed according to customer requirements.

5. Defects elimination after calibrating

The board for the glued beam production gets to the four-sided planning and moulding machine where it is calibrated in the accurate size. Before finger-jointing a board goes through the process of calibration on the German equipment WEINIG Profimat. In this case, the board “opens” its defects that were not visible before.

6. Finger-jointing line

The half-finished product move from the facing machine to the finger-jointing line where the following processes proceed: making the finger-joint, putting AkzoNobel adhesive, pressing in on the length, cutting lamellas to the definite size, and going through the finger-jointing machine that turns short boards into lamellas 12 m long.

After jointing lamellas they are not exposed to any loadings within 2 hours so as the process of adhesive polymerization take place properly.

7. Adhesive application

The lamellas are being cut on two-sided machine before gluing in the press. As a result the surfaces become parallel for the adhesive application. Then the lamella is going through the block where AkzoNobel adhesive is applying. The special texture of the adhesive let a ready product “breathe”. During all period of using the house, the EcoHouse Group glued beam doesn’t allocate toxic substances and is absolutely safe for the human.

8. Press

After adhesive application the lamellas are going into a press where they are gluing together in a beam under pressure of about 10 kg/cm2. In the process of gluing lamellas in a beam, the direction of «growth rings» is set in the opposite to each other side, and due to this fact the glued beam becomes much stronger, there are no cracks in it, and the heat-insulating properties of future house improve. The half-finished product for the glued beams goes to the C.M. Macchine machine (Italy) — Compat 600 — that cut them from 4 sides, sets the necessary sizes and, if it is necessary, bevels the edge.

Further beam machining takes place on the center Hundegger SC2i (Germany). This machine notches connections of any complexity.

9. Notching of a beam profile

The material for a wall element is machined on the automated line of the full cycle Makron that excludes mistakes, caused by a human factor. Here is also the corner (the “cup”) notching is made. The lock of a cup is developed by the Finnish engineers specially for the Makron line that excludes «beam blowing through» and to provides high heat saving of the house construction. The lock is used for the connection of bearing walls and external corners of the house. After that the beam profile, the slots for angular connections and for wood element of the apertures is notched; the dowel and wiring holes are drilled.
