Harmfulness of OSB slabs for health: arguments for and against

Health concerns are frequently raised when thinking about using OSB (Oriented Strand Board) slabs in construction. Popular for its affordability and adaptability in many different applications—including facades—OSB is a building material. However, discussions about its environmental impact and safety are still ongoing.

OSB proponents contend that it provides a more affordable option than solid wood products and plywood. Because it is made of tiny wood strands that have been glued together under intense pressure, it is strong and appropriate for structural use in building facades.

Opponents, however, bring up health issues regarding the adhesives used in OSB production. These adhesives might include volatile organic compounds (VOCs), which over time may release gases that could have an impact on the quality of indoor air. Discussions regarding the long-term health effects on occupants have been triggered by this.

Proponents of OSB point out that appropriate finishing and sealing can allay these worries by lowering the possibility of VOC emissions into indoor spaces. They contend that the advantages of OSB can outweigh any potential health risks provided proper ventilation and installation procedures are followed.

Critics, however, advise looking into substitute materials that provide comparable structural advantages without the alleged health risks connected to OSB. Some alternatives could be traditional materials with a long lifespan and low environmental effect, or engineered wood products made with safer adhesives.

In conclusion, striking a balance between structural integrity, affordability, and health concerns is critical to the ongoing discussion surrounding the use of OSB slabs for building facades. Making educated decisions about the materials to be used in construction projects requires having a thorough understanding of both sides of the debate.

Production technology

It is necessary to understand production technology in order to comprehend how OSB can have an influence on health individuals. Future material should receive special consideration. A single subpar ingredient ruins the entire product.

1. Obtaining raw materials and its processing. As the main component of the OSB, the slabs are used by the woodworking industry – a weekly wood, which was rejected. Wood waste is soaked at a certain temperature and cleaned.
2. Cutting. At this stage, wood chips are obtained from waste by machine.
3. Drying. The resulting raw materials are dried, which takes a certain time. If the chips dry quickly, this can lead to damage.
4. Mixing. To bind wood chips, the composition of glue and resins is added to it, and other connecting components in different volumes may be present.
5. Laying. Using molding machines, the mixed component is laid in several layers. Each subsequent layer is laid perpendicular to the previous.
6. Pressing. The resulting mass is compressed by the press and cut down by a given size.

Wood chips make up the majority of the OSB plates. This part is friendly to the environment. Because formaldehyde resins are frequently included in adhesive compositions, there may be a risk.

Additionally, natural wood can discern the acceptable formaldehyde standard. As a result, discussing the safety of fresh wood is debatable. However, the wood chips for the OSB are regarded as safe because they have passed the processing stage.

Manufacturers who respect their clients and brand assert the material’s security. By their certification, excerpts—rather than the influence of the media—achieve high quality OSB. The chips are gradually bound together by resins; the press merely provides shape. Because of the extended binding time, formaldehyde is able to escape from the plate structure. The substance’s concentration decreases and its effects on human health are not harmful.

Application: pros and cons of

The creators heavily promoted their innovation. Because OSB uses plates to quickly build structures, it becomes very popular, especially in the West where time is valued.

• Strength. The material withstands large loads, and also has high indicators of bending strength, separation and compression. Slabs can be pressed a few hundred kilograms per square meter.
• Low weight. Binding elements based on resin and glue are lighter than wood – this allows you to slightly reduce weight.
• Weak deformation. Slabs can be used as a cladding.
• Noise and thermal insulation. OSB sheets weakly conduct heat. With proper installation, they suppress noise up to 8 dB.

SIP panels are additionally made using OSB:

• The material is easy to process and is easy to mount it.
• Resistant to mechanical exposure.
• Relatively easily tolerates temperature and humidity drops.

These characteristics, along with the material’s low cost and relative ease of production, determine how widely used it is in building. Recently, the material has been used for housing stock in addition to industrial construction.

Drawbacks of the content:

• Direct contact with water leads to a swelling of the material. Material from some manufacturers can increase in size to 25%.
• It is difficult to conduct communications under mounted sheets, as well as change the insulation.
• The material is fire hazard due to the high content of resins. Processing with fire -retaining compounds slightly reduces this factor.
• Subject to damage to fungi and mold, also rodents and beetles can ruin the slabs.
• It costs more than sheets of GKL and chipboard.

This is insignificant in comparison to the fact that prospective consumers believe the material to be unhealthy and do not want to see it used in construction, according to marketing research.

D harm to OSB

Over thirty years ago, the production of plates was first established in Canada. Subsequently, the technology extended to Europe and North America. Western-sourced technological solutions were implemented in the post-Soviet era. Production is mostly borrowed, although some groups are developing less expensive machinery. As a result, some steps in the production process are eliminated or substituted with less expensive options.

Classification of OSB plates

The OSB slabs are marked by manufacturers in compliance with the European standard. Their categorization is determined by the formaldehyde content of the resin. We can discuss the material’s safety based on it.

1. E 0.5. Permissible norm of not more than 4 mg per 100 g of dry slab. More than 0.08 mg/m3 should not be present in the air.
2. E1. No more than 8 mg. Concentration in the air – not more than 0.124 mg/m3.
3. E2. Resin concentration up to 20 mg. Over 0.5 mg/m3 should not be present in the air.

Formaldehyde is present in all categories of material. Environmental standards are upheld abroad because manufacturers are subject to stringent government regulation.

The degree of environmental friendliness of the material

It would appear that OSB plates have no effect on human health if their use is allowed in Western nations. There are a few reasons why not everything in the domestic market is clear:

1. Abroad, manufacturers strictly comply with environmental norms, but on the territory of the former countries of the USSR they often use cheap Asian materials containing harmful substances in quantities dangerous for humans. However, slabs from such materials are popular due to the low cost.
2. In the domestic market, small manufacturers sin in non -compliance with production technology. It is possible to reduce the amount of harmful substance as follows:
3. Layers of the plate are divided into external and internal. For the outer layer, natural resin is added to the chips, and for the internal – chemicals with additional components.
4. Production costs increase, but harmful formaldehyde is sealed inside the slab.

All materials, including wood, paint, and polymers, have pores by nature. Research pertaining to formaldehyde penetration through wood did not involve wood. When selecting OSB, this should be considered.

Vigilance when buying

Recently, the domestic consumer’s financial affairs have not been fed. People attempt to buy materials at low prices as a result, but low prices may indicate low quality material. It will have a substantial amount of formaldehyde in it, much more than what is considered acceptable.

Thus, you should be aware of the following qualities when purchasing glued material:

1. The presence of a pungent odor. Toxic glue gives a sharp unpleasant odor that gives to the nose.
2. The presence of a certificate. This document should receive every seller from the manufacturer. Sometimes the procedure can be voluntary, but a conscious manufacturer will still provide documentation.
3. Marking of the product. Each sheet must be marked. According to OSB slabs, technical specifications are as follows: the indicator of harmfulness for a person is indicated at the end.
4. Price. The low price of the material, as well as the sale in the spontaneous market from an incomprehensible seller will not give any guarantees regarding quality, as well as safety.

It is best to avoid purchasing anything that seems suspect. Spending too much on a high-quality product puts the customer’s health at risk. This is particularly valid for young kids.

Actions after the purchase

Whoever read the article before heading to the store is lucky. These readers can consider their options and balance the benefits and drawbacks.

Formaldehyde doesn’t leak out indefinitely; eventually, even in materials manufactured in violation of environmental regulations, its concentration drops to a safe level. However, to do this, you must take the following steps:

1. Ventilate the material before installation until a characteristic pungent odor is completely disappeared. It is necessary to do the same with the room if the installation is already completed. Imagonation will take a little more time.
2. The surface of the material cannot be wetted with water. Because of this, formaldehyde stands out stronger-in proportion to an increase in humidity.
3. The room temperature should not exceed 30 degrees.
4. If the clothes smell of a poisonous smell, it should be thoroughly washed several times.

If you don’t care about the money, you could at least borrow money for a couple of weeks or purchase an air purifier that has a photocatalytic filter. For a brief period, a toxic material in the air can be neutralized using such a device.

There is a tried-and-true technique to determine with certainty whether the installed OSB-plate is the source of the health problem. You must install an aquarium with fish in a room that has OSB material on it. The fish won’t survive if the airborne formaldehyde concentration is higher than what is allowed.

The room flower Dieffenbachia has the capacity to draw poisons from the atmosphere. Its existence will contribute to a decrease in formaldehyde levels.

There are several important points of contention in the discussion surrounding the possible health risks associated with the use of OSB (Oriented Strand Board) in home facades. OSB supporters contend that because of its strength, affordability, and ease of installation, it is a sensible material for use in contemporary architecture. It is prized for its ability to withstand moisture and maintain structural integrity, both of which can lengthen the exterior life of buildings.

However, the materials used in the production of OSB are the source of worries regarding its potential health effects. When wood chips are bonded together in OSB, formaldehyde-containing adhesives have the potential to release volatile organic compounds (VOCs) into both indoor and outdoor spaces. Long-term exposure to these VOCs has been connected to respiratory problems and other health risks, which has alarmed some medical professionals and environmental activists.

Regulations and manufacturing improvements have reduced formaldehyde emissions in OSB products in spite of these worries. In an effort to reduce any possible health hazards connected to conventional OSB materials, some manufacturers now provide low-VOC or formaldehyde-free alternatives.

In the end, the decision to use OSB for home facades strikes a balance between pragmatic factors and environmental and health risks. The cost-effectiveness and structural advantages of OSB must be weighed against the possible health hazards posed by volatile organic compounds (VOCs) for both builders and homeowners. Reducing exposure risks and maintaining indoor air quality can be achieved by selecting low-VOC alternatives or making sure there is enough ventilation before, during, and after installation.

This article looks at both arguments for and against the effects of Oriented Strand Board (OSB) on health. Although OSB is valued for its strength in construction and affordability, formaldehyde emissions and other chemicals used in its manufacturing process raise concerns about possible health risks. Supporters contend that because contemporary OSB products adhere to stronger regulations and have lower emissions, there are less health risks. Critics draw attention to ongoing worries and offer plywood as an alternative for people who are sensitive to indoor air quality. The purpose of this article is to shed light on whether OSB presents serious health risks, enabling builders and homeowners to choose construction materials wisely.
