Choosing a block house

Block house is a special type of dry molded products that imitate the surface of a rounded log. On an industrial scale, it is made in parallel with the floorboard or imitation of a bar using a special technology "square in a circle". In this case, products of a rectangular or square cross section are obtained from the core of the log, and a rounded shape from the edges. The sawn block-house workpiece undergoes thermal and sanitary treatment in drying installations, after which fastening spikes and grooves are cut out on milling machines.

The original appearance and the possibility of applying both for internal and external works have led to the well-deserved popularity of the block house. Using wooden paneling, in a short time, you can give even the most unsightly facade the look of a freshly built house made of rounded logs, or add a unique color to gazebos and baths made of any materials.

Wooden block house: we understand the varieties

When choosing a block house, first of all it is worth remembering that wood is a living material, breathing and quite capricious. You should not expect a perfectly smooth surface without a single flaw - this is possible only in artificial materials. The tree is characterized by a unique texture and original pattern on each board. However, depending on the grade, the appearance of the block house can be very different.

According to the European quality standard (DIN 68/126/86), molded products are divided into three grades:

  1. Grade A (first grade).
  2. Grade B (second grade).
  3. Grade C (third grade).

Most manufacturers work according to their own technical specifications (TU), which in any case should not differ greatly from generally accepted quality standards.

We will consider in detail the defects allowed in the products of each grade in the summary table:

Possible wood defects Grade A (first grade) Grade B (second grade) Grade C (third grade) Live (light) knots that have grown together in whole or in part Allowed Allowed Allowed Light knots falling out Allowed with a diameter of up to 5 mm, no more than 1 piece per running meter Allowed up to a diameter of 20 mm on a block house plate with an edge, no more than 1 piece per running meter Allowed without restrictions Light knots not fused Allowed up to 15 mm diameter Allowed up to diameter 50 mm Allowed without restrictions Dead (dark) bitches Only captive up to 7 mm in diameter are allowed, no more than 1 piece per running meter Only captive with a diameter of up to 15 mm are allowed, no more than 1 piece per running meter Both captive and drop-downs are allowed. Chips in the knot area, torn and fallen knots, rotten and rotten knots

Only allowed:

on the bottom edge of the grooves - no restrictions;

on the upper edge of the grooves - no more than 5 mm in diameter, no more than 1 piece per running meter;

on the ridge - invisible after assembly

allowed up to 20 mm in size, no more than 1 piece per running meter Allowed Longitudinal cracks on the face plate Through cracks up to 95 mm long at the ends are allowed Through - up to 300 mm long on the front Allowed Core Allowed up to half the length of the board Allowed Allowed Roll (nodular thickening of annual rings) Allowed if it does not affect assembly Allowed if it does not affect assembly Allowed if it does not affect assembly Worm-hole Not allowed No more than three pieces per board length Allowed Rot Not allowed Not allowed Not allowed Color change Not more than 10% of the total surface Allowed Allowed Blue Not allowed Pink and light blue stripes are allowed on no more than 10% of the surface Allowed Ash (bark remains) Not allowed Allowed on the bottom edge of the groove and ridge, invisible after assembly Allowed Processing defects Minor gouging defects are allowed (roughness and small tears at the edge and in the knot area) Rigging on the ridge and other defects that do not affect the assembly are allowed Defects of gouging are allowed not more than 50% of the total area

Some producers also allocate the Extra variety, but it is unlikely that you will find it on the free market. Still, this pleasure is not cheap.

When choosing a block house, you need to take into account that the requirements for grade may vary. Some manufacturers use the AB grade mark. Products of this grade may have defects permissible for grade B, but not more than 50% of the selected boards.

Block house of the third grade is mistakenly referred to as rejection by some buyers. However, it should be noted that most of the defects of grade C are purely external. The quality of wood suffers insignificantly, which is used by craftsmen. Buying a C grade block house, they eliminate visible flaws with putties and wood sealants, polish the surface and treat it with saturated shades of impregnation.

Changes in color - blue and pink stripes - can in most cases be removed with a special wood bleach (for example, "Neomid 500" or "Prosept Eco 50").

Even the appearance of green mold on the planks of a block house is not a death sentence. You can get rid of it by drying the boards in a sunny open place - after drying, the mold is easily swept away with a brush or brush, leaving almost no residue. True, the affected material will need to be additionally treated with a strong antiseptic (preferably in two steps) and sanded.

What is the block house made of or how to distinguish pine from spruce

The main share of all logging of commercial timber in Russia falls on conifers, namely pine and spruce. Accordingly, most of the molded dry products are made from such wood. At the same time, production workers often do not bother with sorting, marking the material released from the machines as "coniferous".

At the same time, between pine wood and if there are certain differences:

Basic properties of wood Pine Spruce Colour Reddish or yellowish White, milky Color stability Over time, it becomes more intense, nobler Retains its original color for a long time Texture Strong fibers Fibers are thin, evenly distributed Density at 12% moisture (permissible moisture content of dry molded products) 480 kg per cubic meter 430 kg per cubic meter Resinousness High content Reduced content Knots and their location A small number of large oval knots arranged in groups Large number of small round knots Resistance to decay High Average Blue resistance (fresh wood) Low High Strength High Slightly lower than pine Reaction to machining The wood is soft, does not crack, lends itself well to processing The wood is harder, the presence of knots can interfere with processing

The table shows that the pine block house has a number of advantages over the spruce one. Therefore, if you have a choice, you need to give preference to pine products.

In addition to the classic coniferous block house, on the market you can find more expensive options from larch, oak, birch, alder and other valuable wood species. Their cost can exceed the price of coniferous products several times, therefore such a block house is made mainly in small batches and on order, and is used as an additional element of decor.

For internal and external cladding of large areas, a coniferous block-house of AB grade is most often used, which is optimal in terms of price-quality ratio.

Working and general surfaces - what are the differences

A wooden block house, like any other profiled products, differs in geometric parameters.

Length

The most common size is 3 and 6 m, and six-meter products are less common due to the peculiarities of production and usually cost a little more than three-meter ones. It is much more difficult to find a block house shorter or longer than the standard three and six meters.

Width

A distinction is made here between a common (with a tongue) and a working (excluding tongue) surface. At the same time, narrow types of block houses are most often used for interior decoration and cladding of terraces, verandas and gazebos. A wide block house is used for exterior decoration of facades of large-area buildings.

Thickness

Measured at the highest part of the rounded part. The thickness directly depends on the width of the block house board.

In different retail outlets, a block house can be measured in cubic, square or linear meters. When buying, you should definitely pay attention to whether the working or total surface is indicated on the price tag. The difference between them is on average 6–7 mm.

Some sellers and manufacturers are cunning, indicating the price in terms of the total surface of the block house, which can be an unpleasant surprise during installation. It seems that 6 mm is an insignificant tolerance, however, when sheathing a large building, due to such a defect, several boards may not be enough.

What else should you pay attention to when buying a block house

Having chosen a block house and calculating the required amount, it will be useful to pay attention to the conditions in which molded products are stored in a warehouse or in a store. Correct storage guarantees the safety of the presentation and operational characteristics of the block house.

Dry molded products require protection from atmospheric precipitation and dampness, but are insensitive to temperature fluctuations, therefore, ideally, they should be stored in closed unheated rooms.

In extreme cases, it is allowed to store the block house under closed canopies, but subject to certain conditions:

  1. Store in original packaging to protect from dirt, dust and moisture
  2. Use of pallets and pallets
  3. Natural ventilation - there should be a distance of at least 15–20 cm between the floor of the warehouse or shed and the bottom stack.

Of course, in no case should you buy goods in dirty packaging or stored in bulk - such storage often leads to a violation of the geometry of the blockhouse board.

In the next article, we will tell you in detail about the installation of a block house: how and from what materials to make the crate, which insulation to choose, how to make high-quality cladding. In addition, you will learn which antiseptics are best for treating a block house facade.
