<p><strong>Manufacturing process</strong></p><p>Manufacturing of the glued timber eco house is done in our European partner company&rsquo;s manufacturing plant.&nbsp; Our partner company during its 10 years in the timber building manufacturing business has obtained the ISO 9001 certificate of quality, as well as the certificate OHSAS 18001, which is a testament to our partner company&rsquo;s serious regard to the environment and issues of work safety. The company&rsquo;s strategy is aimed at constant development and introduction of new technologies into manufacturing. <br /><br />The company has also received the right (certificate) to mark the glued wood building parts with the CE compliance mark (certificate No. 0672-CPD-I14.21.36), which attests that the glued wood buildings parts manufactured by our company comply with the requirements of appendix 3.4 of harmonised standard DIN EN 14080 ZA.</p><p><strong>Glued solid timber constructions and their usage in construction</strong> </p><p>Timber is the only widely-available material which is naturally renewable. From the viewpoint of life-cycle, timber as a construction material is environment-favorable for several reasons &ndash; it reduces the usage of natural resources, energy consumption, carbon dioxide emissions and waste; it is environment-friendly, well-suited for designing and creation of living-space, and it is emotionally effective.</p><p><img style="width: 120px; height: 81px" src="/data/detala_3.jpg" border="0" alt="" hspace="7" vspace="7" align="right" />To use timber resources more effectively and improve upon timber characteristics, timber gluing has long been preoccupying the minds of people. Initially, there were problems in manufacturing of glued timber, as there was no adhesive sufficiently resistant to fluctuations in humidity and temperature. This was solved only in the fifties of the 20th century &ndash; it was when the creation of adhesives resistant to atmospheric influences allowed the development of factory-manufactured glued timber building parts. </p><p>For the manufacturing of bearing timber constructions, our company is using a made-in-Sweden melamine-urea adhesive 1247 with hardener 2526, which has been tested and approved for the production of load-bearing timber structures by Norsk Treteknisk Institute (NTI), Norway, Centre Technique du Bois et de l&rsquo;Ameublement (CTBA) France, Material-prufungsanstalt Universitat Stuttgart &ndash; Otto-Graf- Institut (MPA), Germany and SKH/KOMO (DHBC 32389), Holland according NE 302 part 1 to 4 and DIN 68141 with adhesive: hardener ratios of 100:100 to 100:20 part by weight. Melamine-urea adhesive 1247&nbsp; has been deemed appropriate for bonding of all types of timber constructions, whose requirements are in accordance with DIN 1052 and EN 386 (bonding of bearing timber constructions). </p><p><img src="/data/detala_4.jpg" border="0" alt="" hspace="7" vspace="7" align="right" />Glued timber building parts are mainly manufactured of spruce, which is characterized by both firmness and elasticity, low shrinkage and high durability. Bonding of much smaller timber elements ensures that the building parts are particularly resistant, uniformly durable and stable in form. A body of much smaller parts bound in this way allows creating building parts of almost any shape. It is also important to note that glued timber building parts are ecologically clean, light, durable, with good heat insulation, suppress noise and vibrations, are resistant against aggressive substances and liquids, and are easy to treat. Also of importance is the inclusion of such glued timber building parts to ensure building microclimate factors. Timber improves health and comfort, reduces stress and effectively regulates moisture in rooms. We offer manufacturing of high-quality glued timber building parts for bearing constructions with the following cross-sections: </p><p>- Thickness/width: from 1.18&rdquo; to 9.06&rdquo; (30mm to 230 mm) <br />- Height: from 3.15&rdquo; to 4.92ft (80 mm to 1500 mm) <br /><img src="/data/detala_5.jpg" border="0" alt="" hspace="7" vspace="7" align="right" />- Length: up to 17.5 yd (16 m) </p><p>The term of the completion of the order is dependant on the cross-section of the ordered building parts. For instance, if the cross section of the ordered glued timber building parts is 3.93&rdquo; x 7.87&rdquo; x 10.94 yd (100 mm x 200 mm x 10000 mm) , then a volume of 26yd3 (20m3 )is produced in four working days. In case of need, we can carry out timber building part coating with antiseptics and fireproofs. Our manufacturing capacity for glued timber building parts in a month is 785 yd3 to 1308 yd3 (600m3 to 1000m3.) </p><p><img src="/data/detala_6.jpg" border="0" alt="" align="left" /></p><p>&nbsp; <img src="/data/detala_7.jpg" alt="" width="120" height="81" align="baseline" />&nbsp;

To ensure the quality of a GSTC product, the company must adhere to all requirements of construction manufacturing and raw materials, end-product and quality control determined by the standard LVS EN 14080 &quot;Timber structures &ndash; Glued laminated timber &ndash; Requirements&quot;. </p><p>In accordance with the standard LVS EN 1194, &quot;Timber structures &ndash; Glued laminated timber &ndash; Strength classes and determination of characteristic values&quot;, GSTC is dividend into four strength classes, starting from the weakest: 1st class &ndash; GL 24c; 2nd class &ndash; GL 28c; 3rd class &ndash; GL 32c and 4th class &ndash; GL 36c. </p><p>Testing of GSTC static bending strength can be done using special devices (in <strong>the image above &ndash; a two point static bending strength testing device</strong>). </p><p>Similarly to GSTC, several strength classes have been set for saw-timber. In accordance with LVS EN 338 &quot;Structural timber &ndash; Strength classes&quot;, depending on the nominal strength in static bending, it is dividend into 12 classes (C14 to C50) for softwood and 6 classes (D30 to D70) for hardwood. Virtually all saw-timber of softwood grown in the Baltic countries under normal conditions, without substantial faults, is of classes C14 &ndash; C24, however it is possible to manufacture GSTC of any strength class. </p><p>GSTC is divided into two types: <br />1.&nbsp;Homogenous GSTC &ndash; constructions that are made by bonding lamellas of similar strength, of single or several wood species. <br />2.&nbsp;Combined GSTC &ndash; constructions that are made by bonding lamellas of different strength, of single or several wood species. <br /><br />The symbol after the GSTC strength class indicates for what type of construction materials the respective requirements are set; e.g., GL 32h is homogenous GSTC with nominal strength of 32 N*mm-2. <br /><br />For the combined type GSTC, at least 2 higher strength class lamellas are placed in the tension or compression zones of the construction &ndash; in the outer edges &ndash; and lower-quality materials are used in the middle. Such manipulations do not affect the construction&rsquo;s bearing capacity in static bending, and allow utilizing lower-quality materials more effectively. <br /><br /><img src="/data/detala_14.jpg" border="0" alt="" hspace="7" vspace="7" align="right" />The conformity of raw materials (lamellas) and GSTC to these strength classes is tested by special devices. It is done by the manufacturer or another competent authority. For testing of lamellas and GSTC, the standard LVS EN 408 is used (<strong>in the image &ndash; solid timber constructions, bound in the wide side, using lamellas of similar species and strength</strong>). </p><p>For GSTC quality control, the company utilizes the standard LVS EN 385:2002 &quot;Finger jointed structural timber &ndash; Performance requirements and minimum production requirements&quot;, which determines the requirements for fingerjointed connections (in <strong>the image below &ndash; a fingerjointed connection for manufacturing of a fingerjointed lamella</strong>), as well as the minimum requirements for glued finger-joint milling and bonding.&nbsp; </p><p><img src="/data/detala_15.jpg" border="0" alt="" hspace="7" vspace="7" align="right" />The Standard determines that fingerjointed connections are classified based on static bending tests on the narrow side. This classification is determined by the lamella manufacturer, as self-declaration, showing bending strength value or class for the corresponding batch of products. If it is required to prove the strength of a finger-jointed connection to the purchaser of fingerjointed constructions, the company can do it by carrying out appropriate tests in accordance with the standard LVS EN 408:2003 &quot;Timber structures &ndash; Structural timber and glued laminated timber &ndash; Determination of some physical and mechanical properties&quot;. The fingerjointed lamellas are classified by the standard DIN 68140 &ndash; 1. Part 1 of this Standard determines the required fingerjoint size, possible fingerjoint milling directions, technologic requirements of pressing, applicable adhesives, quality of raw materials, nominal strength of finger-jointed connections, as well as quality control. </p><p>Sorting lamellas by the classification determined in DIN 68140 &ndash; 1, it is possible to choose the supplier in accordance with the required lamella usage. If the company manufactures GSTC of lamellas, which are made by bonding the wide sides, it is possible to estimate the construction strength class. According to DIN 68140 &ndash; 1 p. 5.4, lamellas by nominal bending strength are classified in compliance with the strength classes determined by DIN 4074-1 (see table). <br /><br />Characteristic bending strength N*mm-2</p><p><img src="/data/tabula.jpg" alt="" width="980" height="243" align="left" /></p>
