What are the advantages and disadvantages of a laminated

Wooden houses are becoming popular not only in Russia, which is famous for its natural wealth, but throughout the world. The main role is played by the environmental component. No other building material can match wood in many ways. Below we will describe in more detail what a glued laminated timber is, the advantages and disadvantages of which are being discussed this way today.

Wooden houses are built from:

1. logs;
2. timber, including:

• the usual;
• profiled;
• glued;

1. rounded beam.

The main characteristics of glued laminated timber

One of the most interesting lumber today is considered to be glued laminated timber. He came to us relatively recently, a little more than 20 years ago, but quickly became popular among developers.

Glued laminated timber, as it turned out, has almost no flaws with which profiled timber and a round log, made of a solid tree trunk, sin.

Before delivery to the construction site, glued laminated larch, oak and pine beams are factory dried to a moisture content of 8-12%. This, of course, does not allow to get rid of shrinkage completely, since after laying the timber “dries out” in natural conditions by another 3-5%, but this is significantly lower than that of a log or a shaped regular bar.

Lumber is made of lamellas, parts of wood, which are glued together under a press according to the developed calculations. To increase the material resistance to high loads, the fiber directions of adjacent panels do not match. This makes it possible to increase the resistance by almost 70%.

Benefits

• Low weight (about 700 kg / m³), which makes it possible to build buildings on shallow and light foundations. Thus, the cost of construction is significantly reduced.
• Ecological purity of lumber. The tree has long been known for its healing properties, for example, the "air conditioning" of indoor air. Due to the unique structure, it contributes to natural air exchange, which makes it possible to maintain a comfortable atmosphere in summer and winter.

Wood also has anti-toxic and antiseptic substances that remove toxins and other human waste products from the premises. It has a low natural background radiation, has a beneficial effect on our body.

• Short construction time. One of the most significant points. The technology allows you to assemble a house from glued laminated timber and a log with an area of ​​200 m² in about one week, and the entire project from concept to commissioning of the object will not take even 9 months. And it does not depend on the time of year, and the attached instructions allow you to do this with minimal cost.
• Geometric stability. Over time, glued laminated timber changes its size by about 1, which is 10 times smaller than ordinary sawn timber from a single piece of wood. The building is monolithic, in which there are no internal stresses.

• There are no external cracks. This is due to the technology, since the lamellae are cored outward. Therefore, if microcracks arise, they will only be inside the product.
• High strength timber. This allows you to increase the size of supporting structures, for example, spans.
• Resistance to moisture, fungi and other biological destruction. All this was made possible due to the absence of cracks and crevices. In addition, the material is in the factory antiseptic processing.
• External and internal furnish is not required. Houses from a bar are beautiful enough. The naturalness of wood is underlined by a smooth surface.

• Fire resistance This is due to the absence of cracks and crevices where air can flow. In case of fire, the timber burns to the ground, but the design does not collapse.
• Durability. Care of the house does not give the owners trouble.

disadvantages

Like any material, glued laminated timber cannot be perfect.

Therefore, it has its drawbacks that every consumer should know about.

• The appearance of cracks on the ends. Rarely, but this phenomenon can occur, although it does not affect what it does. This usually happens because of the active sun and long construction.

Tip: when assembling it is necessary to process the ends with a special compound, then such defects of the laminated timber do not appear.

• Shrinkage. It really can be, though not the same as in a timber or rounded log with natural moisture. But, nevertheless, shrinkage is not so critical, therefore it gives the opportunity to move into the house after construction.

• Heat. The effectiveness of this component of comfortable living in the first place depends on the number of windows in the house, floors and properly made roofing. The walls play a secondary role here.
• Durability. In fact, this is a fairly new type of wooden products, so it’s not yet possible to talk about the timing of its use.
• Environmental friendliness. Calling glued laminated timber an environmentally friendly material can be a stretch. Although its main component is wood, it also uses an adhesive base, which in many cases is far from perfect. These disadvantages of the house of laminated veneer lumber today almost leveled.

Tip: when ordering, check the glue certificate with the lumber manufacturer. Today the industry is gradually abandoning harmful components, such as formaldehyde.

• The wall of this lumber resembles a "stone" or "concrete", therefore, many skeptics cite such flaws in houses from glued lumber as an example. This, of course, is not true, although if you purchase lumber “cheaper”, you may be faced with this phenomenon.

In fact, it is vapor-permeable and can “breathe” like a normal tree. The microclimate in the buildings of laminated veneer lumber corresponds to the usual house of wood.

Conclusion

Wooden house - a great place to relax and stay. Here it is possible to breathe deeply with this healing air that will accompany the household all their lives. Wooden architecture is known in Russia since time immemorial, and hut and tower, built with his own hands, still stand.

Choosing between materials for construction, pay attention to the glued laminated timber. Although it is more expensive than all other lumber, but it is safer than all the others and with its help you will be able to realize the most interesting plans.
