What to choose Glued laminated timber or regular? Which beams are best? Is it worth saving? Overview and Tips Construction of country houses from wood building materials is very popular. And many are wondering which timber is better, ordinary or glued. Having studied the characteristics of these species, you can decide which one you need.

Which is better: glued timber or ordinary?

Let's consider the main indicators of solid and glued timber:

  • cost;
  • environmental friendliness;
  • durability;
  • performance.

Features of ordinary timber

Solid timber is the most common building material due to its low cost.

It is obtained by the method of four-sided log edging. Of the shortcomings, one can point out the absence of an ideal bar of a large section, since tree trunks have natural defects, in the form of curvatures, bends. Internal shortcomings can only be discovered after using the material and operating it. For the construction of inexpensive summer cottages and houses, this material is most often used.

Quality characteristics of a conventional bar:

  • its wide distribution makes it easy to buy material, quickly build a house, but additional work is required on finishing and cutting;
  • the appearance of the house is unpresentable, and becomes aesthetic only on condition of comprehensive additional finishing and thermal insulation of the seams due to shrinkage of the material;
  • with shrinkage and shrinkage that occur over several years, significant cracks may appear;
  • natural moisture is an excellent environment for the development of microorganisms, but with additional processing and finishing, wood can resist the growth of fungi;
  • serious finishing work and constant maintenance of the building will increase the durability of a wooden house;
  • solid timber - like a rounded log - the most environmentally friendly material,
  • despite its simplicity work, requires additional costs during their implementation;
  • from a solid b rus you get a real wooden house, but the heat exchange in the interconnections leads to additional heating costs;
  • with a low cost of such a bar, you will incur serious costs for finishing.

Profiled timber and valuable wood species

Consider also the popular dry profiled timber made of spruce, pine, cedar or larch, which is given the desired geometric shape. In construction and subsequent operation, it is considered more convenient than the traditional cylindrical one. The inner side of the bar is flat and planed, and the outer side is made in the form of a semi-oval, or it can also be flat. There is a groove and a spike on the sides, which allow you to fasten the timber to each other quickly and efficiently.

But do not forget that profiled timber is also a tree of natural moisture, which has all its characteristics.

Features of glued laminated timber

Glued laminated timber is produced using a complex technology, including the production of boards from logs, drying, processing, gluing and cutting the timber. Due to the careful processing and production of several lamellas, such a bar is more promising and reliable than the usual one. Often such timber is used in half-timbered houses (looks great) People who do not save on building a house often choose this more expensive option.

Pros and cons of laminated veneer lumber

  • the geometry of laminated veneer lumber reduces the construction time of a house to a minimum;
  • during operation, the aesthetics of the house does not lose its initial appearance;
  • this material is strong and almost not subject to shrinkage;
  • due to the optimal moisture content of glued beams and a special antiseptic coating, it successfully resists the development of fungi;
  • the durability of the material has not been established , since it appeared relatively recently (30 years ago), but during its production all the subtleties of operating wooden houses are taken into account;
  • environmentally friendly material can be called with a stretch, due to the fact that special glue is used in its production;
  • the costs of finishing work are minimized;
  • a warm house is obtained from glued beams, which is immediately ready for use, but the lack of air and steam circulation through the material worsens its microclimate;
  • high material cost (exceeds the price of a solid material by 2- 3 times) is compensated by the minimum cost of finishing and maintaining the original appearance.

From all of the above, it is clear that glued laminated timber has strong advantages over solid timber.

But the usual timber is quite suitable for the construction of summer cottages that do not have high performance. Such a house will be environmentally friendly and suitable for summer and winter (pre-insulated) living.

Knowing about the tangible difference in price (the average price for 1 cubic meter of ordinary timber ranges from 8-10 thousand rubles, and glued - 20-27 thousand rubles), and the purpose of construction, you you will easily make the right choice from laminated veneer lumber or ordinary.

Also, an excellent option would be to combine glued laminated timber, with the usual one, you can use glued on the main facade, where it will be constantly visible, and use the usual one from the back and sides of the house. This is often used in half-timbered frame houses.

How to avoid deceiving sellers when buying laminated veneer lumber

When purchasing this material, you have two ways:

  • buy on the construction market;
  • order at the factory from the manufacturer.

The first option is very dangerous. There is a high likelihood of fraud in construction markets.

Deception options are different. For example, you order a regular or glued timber of a certain size.

They make a delivery to you, and then it turns out that its size is actually a little smaller. It turns out that you overpaid.

Always check the material before loading. Take a tape measure

with you and measure each bar. Be present at the loading, in the markets they may try to slip a marriage.

How to determine the marriage of laminated veneer lumber?

View the material along the horizontal bending lines to select the timber that led. It happens that the timber comes with wane (bark is visible on glued boards), or with uneven cuts and cuts, or it may be insufficiently sanded.

But the most unpleasant thing is when dishonest manufacturers do not follow the drying technology or use low-quality glue. Such a bar can bend, it flakes off and sticks apart over time.

Low-quality glued laminated timber is glued from 3 - 4 thick boards, and a good one of 7 - 8 is thin.

Pay attention to their number.

Experiment.

If you still buy glued laminated timber on the market, then conduct an experiment. Ask to cut off a small part of the bar. Weigh and record its weight.

Boil it for 2 hours in water. After drying, the cut of the bar should return to its original weight, and if it is unstuck, then it was made without observing the norms.

Do not trust a bar packed in plastic wrap. He, too, can be crooked and terribly planed.

The second option is an order from the manufacturer at the factory.

Do you know why the quality of the timber purchased on the market differs from that produced at the factory? The shopkeepers are dirty, they save on repairs and salaries for employees. Therefore, the movers do not care if the expensive timber fell and was damaged.

Equipment (drying chambers, cutting lines, sorting) is bought as cheap as possible. In principle, we are not talking about quality control.

At serious mills and enterprises, equipment costs millions, workers are trained, work in overalls and are under control.

Such enterprises have already gained credibility and they will not tarnish their name with low-quality products. Quality control is mandatory.

Verified suppliers of such materials, such as Sokolsky Dock, Dok78, Vyshnevolotsky Lespromkhoz, work with European markets and produce very high quality timber.

How to save when buying

Often high-quality timber is used to construct technical buildings, for example, commercial buildings in markets. Over the years, the timber becomes even drier and stronger.

In many cities, such buildings are demolished and dismantled every month.

Drive into similar demolitions of buildings. You can buy quality material there at a very low price. What to choose Glued laminated timber or regular? Which beams are best? Is it worth saving? Overview and Tips

To use this trick or not is everyone's business. But you can really find old material for a ridiculous price and build a small house with a budget of up to 100 thousand rubles.

And if you think that you cannot afford to build a house due to lack of money, then this issue can be solved by approaching the issue of using old building material wisely.
