Features of production and technical characteristics of the OSB of the plate for the exterior decoration of the house

Oriented Strand Board (OSB) is an economical and adaptable material option for appealing to the outside of your house. One kind of engineered wood product is OSB, which is created by compressing and adhering wood strands together under intense pressure. Its strength, affordability, and longevity make it a popular choice for exterior applications in construction.

To guarantee that OSB withstands the rigors of outdoor exposure, it goes through particular manufacturing processes when used for exterior house facades. These panels are typically treated to withstand weathering and moisture, which allows them to be used in a variety of climates. The way the wood strands are oriented during production also adds to OSB’s strength and durability, enabling it to endure the strains of structural and ornamental applications on building facades.

Technical attributes set OSB apart from other materials frequently utilized for external home siding. OSB panels, in contrast to conventional plywood, are built in layers, with each layer placed strategically to maximize strength. Because of its structural integrity, OSB requires less maintenance over time and has a longer lifespan than plywood due to its reduced susceptibility to warping and delamination.

A noteworthy benefit of OSB for external house facades is its extensive range of finishing options. Builders and homeowners have more options when it comes to achieving the desired aesthetics because OSB’s smooth and uniform surface accepts a wide range of treatments and finishes, including paints, stains, and textured coatings. Because of its versatility and financial advantages, OSB is now a preferred material for use in contemporary building projects.

The manufacturing process of OSB (Oriented Strand Board) and its technical specifications related to exterior house decoration are examined in the article "Features of production and technical characteristics of OSB panels for house exterior decoration." It discusses how OSB is made, emphasizing that it is made up of wood strands that have been resin-bonded and pressed into panels. The article compares OSB to other materials, such as plywood, and discusses its weather resistance, durability, and suitability for outdoor applications. It also discusses important aspects such as thickness, resistance to moisture, and environmental factors when selecting OSB for facades, offering useful advice to builders and homeowners who want to improve the exteriors of their homes with durable and affordable materials.

Features of plates

• width – 15–25 mm;
• length – 75-150 mm.

In this instance, the elements in the plate’s internal (transverse) and exterior (longitudinally) layers differ. Although it can be challenging to tell apart this orientation, the chips’ size is immediately noticeable. Following the guidelines will make it easier to tell OSB plate apart from other materials right away.

There are five key stages in production:

1. Choosing wood. To get high -quality plates, the creators buy only poplar, pine, spruce and aspen as the starting material.
2. Preparation of chips. The whole process is automated. The logs are cleaned, sawn into small pieces, and then it is thrown out. Chips are made only along the fibers. After the material has acquired the necessary shape, it is sent to dry.
3. Preparation of a pressing mixture. Next, the shavings are mixed with the binder. It includes wax, phenol -formaldehyde resin, paraffin and boric acid. If you mix all the components in certain proportions, you get a persistent polymer.
4. Formation. When the mixture is ready, it is served along the conveyor to the molding station. A uniform layer of raw materials is obtained here.
5. Pressing. The material is subjected to processing at a pressure of 5 Newton at mm 2, while the ambient temperature should not exceed the value of 200 degrees Celsius. After such processing, the edges are necessarily cut, and the blanks are left until completely polymerization for 48 hours.

Controlling the material’s quality and giving the plates their standard sizes will be the last steps. OSP shelves in stores can only be accessed after this.

The article may pique the interest of readers due to the introduction of various acronyms. Everything is very easy to understand:

• In English, the name sounds like “Oriented Strand Board”, use its abbreviated OSB version;
• When translating into Russian, the name “oriented-brown plate” and its abbreviated version of the OSP are obtained;
• The third variation of the OSB is also found – an English reduction recorded
  Russian letters.

The criteria for the quality of the material

Since the production technology used to make these wood panels is different from that of other plates, there are additional technical differences. You need to consider all the subtleties when selecting the OSB of the slabs for external decoration.

Moisture resistance and water absorption

Natural materials, like wood, react when the surrounding humidity rises. The plates only need to be consistently kept dry because they are composed of wood. Natural material is not protected from water by the composition’s polymer component.

The material of the stove will eventually absorb the water if it is submerged in it. This will shorten the service life and cause a decline in strength and resistance to adverse stimuli. The OSP are submerged in water and the amount of material swelling is observed in order to determine the extent to which they can withstand the effects of moisture.

The highest grade 4 slabs are found in the smallest indicator. Just such a material is used for the construction of a frame house or other buildings.

Strength

Since all businesses must adhere to a single standard, there may be very slight variations in the material’s strength between manufacturers. Look for the following signs on the strength slabs:

1. Bending strength along the main and side axis.
2. The elasticity module for the main and side axis.
3. Stretch to stretching.

Quality certificates list all of the indicators. Should they decline to produce the relevant paperwork at the point of sale, you shouldn’t buy it because it isn’t worth it.

The ability to hold fasteners.

The OSB plates can be fastened using any known fastener because the slabs are strong and have a fibrous structure.

• nails;
• self -tapping screws;
• brackets and others.

According to the manufacturers, fasteners can be placed up to 10 mm from the edge, and you can do so without worrying about stratification, breaking, or other unfavorable outcomes. In the event that the stove needs to be fixed even closer, it is advised to work cautiously and avoid going over the 6 mm mark.

When fixing wooden sheets, they correctly follow a few guidelines when selecting fasteners:

1. Length exceeds the thickness of the plate by 2.5 times. Moreover, the minimum length is 50 mm.
2. If a bracket is used for fixation, then the thickness of the wire cannot be less than 1.5 mm.
3. Fix the material with steel or stainless fasteners.
4. The shape of the hat is necessarily flat.

It is advised in the material’s usage instructions not to embed the fasteners too deeply into the stove, as this will make it extremely difficult to remove.

Insulating properties

We will now discuss the OSP plates’ steam-passing efficiency. The majority of manufacturers don’t even list a steamability coefficient. A parameter that indicates how much the OSB plates are poorly missing pairs relative to the air is one of the characteristics.

To the uninformed layperson, these indicators mean nothing at all. However, if you search through the literature and perform some additional calculations, you’ll discover that the slabs essentially don’t miss steam. There is a 0.0031 mg/(m · h · PA) coefficient.

The material can hold onto the heat in the room because it is made of wood. However, the plate’s density and thickness both affect this indicator. The option will save more heat if it is thicker.

Large sizes, stability of shape

OSP plates are made of a very plastic, suppressive substance. This is useful when sheathing or constructing a structure with an irregular geometric shape is required. Plates are able to:

• grind;
• drill;
• strict;
• Sprinkle and so on.

Any tools, whether professional or homemade, are used for this kind of processing. The most important factors are that the tool should be used clearly and slowly, that the plate’s surface is level, and that the blades are made of solid metal.

Counseling! Wear personal protection equipment at all times when processing woody OSB plates. Do not disregard this advice as the resulting dust poses a health risk to people.

Environmental Safety

The majority of customers are curious about the materials’ level of danger when it comes to synthetic resins. After conducting research, the manufacturers of the OSB for the slabs came to the following conclusion:

1. The amount of resins in the composition is very small only 3% of the weight of the dry slab.
2. The largest number of vapor of caustic substance is distinguished in the first year of operation, but it is still less than that of chipboard and MDF.
3. Further, phenol is formed only with severe heating.

Every year, the production of slabs is enhanced by the substitution of safer, yet equally dependable, components for the phenol-formaldehyde resins that once again make up the composition.

Fire resistance

The lowest combustibility class, or easily ignited materials that burn spontaneously without a source of fire, is represented by woods that are oriented. Consequently, a layer of fire-resistant material must be installed if the material is to be used as an exterior or interior decoration.

If this is a heater, mineral wool works well, and tiles or plaster can be used for decoration. It is impossible to safeguard the lives of the building’s occupants without these occurrences.

In response, manufacturers are attempting to add unique non-combustible components to the material in an effort to increase its combustibility. Following the binder’s full polymerization, special impregnations are applied to cover OSB plates.

Aesthetics

Because they are used as decorating surfaces, the slabs lack remarkable beauty. The material works well with every decorating technique. Plates are able to:

• stain;
• cover plaster;
• Close with tiles or decorative stone and so on.

Make sure to consider strength when selecting decorative materials. If the option is too heavy, it won’t be suitable.

How to choose OSP

On the market for building materials, OSB plates are available in four different varieties. Consider the environment in which the material will be used while selecting it. Since wood cannot withstand such an effect for very long, the humidity indicator is particularly crucial.

For external walls

Here, using OSB 3 and 4 is preferable. These solutions can withstand prolonged periods of high humidity and have the strongest strength indicators. Class 3 and 4 plates can be used to make skin-skinned objects and building structures.

For internal coating

Inside, where humidity is typically lower, grade 1 and 2 slabs work well. They have significant indicators of moisture absorption, but they are strong enough to support the weight of finishing materials. Therefore, it is preferable to select third or fourth grade slabs for any work you intend to do in the kitchen or bathroom.

Plates use and installation technology

High-quality material must obviously follow installation technologies in order to complete the tasks assigned to him. If you take all necessary steps, the outcome will be suitable.

When installing floors

The OSB plates are selected for placement:

1. Black flooring.
2. Seamless floor on a wooden or concrete base.
3. Floating floor.

The following is an approximation of the work technology:

• We equip reliable waterproofing. This item is definitely not allowed if the floor is built on the ground floor;
• The long side of the two plates should be connected on the lags or on additional supports;
• Two sides are fastened with a groove, a ridge or a N-shaped plate;
• If absent, the groove should leave a gap of 3 mm;
• If you make a floating floor, leave a gap of 1.2 cm from the wall.

When installing internal partitions at home

On interior partitions, plates can be installed either vertically or horizontally. Thermal insulation is installed even before the skin begins to grow if wall insulation is to be installed.

Follow these steps to sew the wall:

1. Build a frame of wooden bars or metal profile.
2. When the first plate is installed, the gap is left from the floor or foundation 1.2 cm.
3. Between the two OSPs leave a gap of 3 mm.
4. To the ceiling, they also leave a space of 1.2 cm.
5. No need to fill the gaps.

External facade works

SIP panels are used for lining the exterior structure or the frame house structure. This design has two layers of OSP plates with polystyrene foam acting as an insulator in between. It will require you to read more literature because the technology involved in installing SIP panels is a little more intricate and has its own subtleties.

Production Features	Technical Characteristics
OSB (Oriented Strand Board) is manufactured by compressing layers of wood strands with adhesive.	It exhibits high structural strength and dimensional stability, suitable for exterior use.

Oriented Strand Board, or OSB, has become a popular and strong choice for external house cladding due to its affordability and structural integrity. Because OSB is made of resin-bonded compressed wood strands and is weatherproof, it is a common material used in construction.

Dimensional stability is one of OSB’s main benefits when used outside. OSB is designed to minimize expansion and contraction brought on by variations in temperature and moisture content, in contrast to conventional plywood. This characteristic lessens the chance of the house’s facade warping or cracking over time by preserving its integrity.

Additionally, OSB provides superior strength and impact resistance, which are essential qualities for shielding the home from outside elements like wind, rain, and impacts. Because of the structural rigidity provided by its layered construction, the building envelope’s overall durability is improved.

OSB is renowned for its strength as well as how simple it is to install. Because of their strength and light weight, the panels are easier to handle and require less labor when being built. OSB can serve as an external cladding material for a long time with proper installation and upkeep.

All things considered, OSB is a sensible option for external house cladding because it combines low cost with dependable performance. It is appropriate for a variety of climates and architectural styles due to its resistance to moisture and ability to maintain dimensional stability. When used in residential construction, OSB provides a workable way to achieve both structural resilience and visual appeal, whether on its own or in conjunction with other materials.
