history of the invention of drywall

dry plaster was invented in the United States.The exact translation of the term from English drywall - dry wall.In the late 19th century, it was invented by the prototype of drywall: a sandwich of several dozen layers of paper and layer of plaster.At the beginning of the 20th century building material has undergone improvements and took the form familiar to modern times.Later we added design edges of drywall.The first producer of plasterboard from Sweden launched a new construction material for sale in Europe.

Properties drywall from a position of environmental

Composition drywall:

1. Gypsum - a natural mineral product.It is made from sedimentary rocks.By purifying the feedstock from impurities, grinding, drying at a temperature of 1800 obtained gypsum powder.

2. cardboard sheets that serve as reinforcement.7

3. Gypsum mixture is poured between two layers spetskartona.

4. cardboard sheets are folded around the ends, closing the longitudinal edge of the sheet and forming a protective edge.

5. At a special car attached to the ends of the original form.

6. Produced plaster strip with lots of kilometers.Unit-cutter cuts the tape from the continuous sheets of standard length -. 2.5 m

7. Clipped standard drywall sheets are sent to the oven for drying.8. The finished product is packed in appropriate packages.9. Modern industry produces several types of plasterboard:

  • ordinary drywall.It consists of cardboard and gypsum layer.For surface used gray cardboard.Blue color marking is applied on top.Not impregnated with organic or inorganic, it is absolutely harmless to health.Suitable for interior decorating;

  • moisture-resistant drywall.Sheets before drying treated with a special anti-fungal and anti-bacterial compound that prevents soaking.Leaf differ in a pleasant green.Scope of construction materials: for bathrooms, showers, bathrooms, all rooms with high humidity;
  • fireproof drywall.Reinforcing mesh with fire-resistant properties.The sheet can withstand the impact of an open fire.The glass is used as a protective refractory material.When burned cardboard lining is sintered and maintains structural integrity.The combustion process is not accompanied by the release of carcinogenic volatile compounds;
  • combined plasterboard.Processing complex protection from wet and combustion.The structure does not include heavy metals or toxic additives.

If products with additional protection is available on the modern equipment from the manufacturer, comply with established health standards, all supplements are tested for compliance with safety regulations, providing the customer the relevant certificates.Determined harmlessness of protective materials to the environment according to the standards of European requirements.

Plasterboard harmful properties

harmful properties of drywall can be in violation of technological processes.In cases of using manufacturer unverified safety of substances or additives.When using mineral raw materials for gypsum from adverse environmental conditions for the area.Check compliance with the norms of the drywall and guests are required when buying the material, require the provision of quality certificates, conclusions sanitary epidemiology services, to purchase construction materials for a reliable company or from a reputable manufacturer.It turns out that the responsible approach to the manufacture of plasterboard manufacturer, excluded contaminants and damage to health.6

drywall harm health

In identifying the harmful effects of the drywall on the body should pay attention to the operating conditions and the scope of the construction materials:

  • plasterboard work is inevitably linked with a sharp material.The dust released during this gets into the respiratory organs.Constant inhalation of gypsum dust leads to irritation of the mucous membranes and provokes the development of SARS. Tip: work associated with the saw cut, cutting, drilling sheets to produce a respirator.Upon completion, a vacuum cleaner to remove accumulated dust-like debris.
  • Improper use of drywall.When using conventional gypsum board structure for the walls, in wet areas occurs following process: in the porous structure is formed under the influence of damp breeding ground for mold and fungus life activity of microorganisms.The formation of these colonies, brings harm to the body, it is the source of the unpleasant "wet" or "basement" smell in the room.

  • Performing slopes window openings of conventional drywall leads to condensation in the inner cavity of the slope, there is a moldy material.As a result, in the apartment penetrate mycotoxins.They adversely affect the immune system, causing episodes of allergic diseases. Tip: think carefully about the use of drywall, use the building material for the intended purpose.Use moisture-resistant drywall to finish slopes of window apertures indoors.If you treat a normal plasterboard fungicidal composition, the condensation will not damage the appearance, does not deform the material and will not create conditions for the development of harmful microorganisms on the surface.
  • sometimes occur as part of the drywall compound formaldehyde or phenol.This is not a frequent phenomenon occurs through the fault of the manufacturer.Choosing the material, do not trust cheap varieties drywall, especially in China.Domestic manufacturers are always supply marketable products accompanying documents.Demand the presentation of certificates of conformity at the point of sales.

Arguing about the dangers of drywall, consider the specific situation correctly use the material for its intended use.

Practical advice on how to reduce the harm from drywall

  • Plasterboard not recommended for use in a confined, unventilated space with humidity levels higher than normal.To trim or finish saunas, steam baths, showers, Jacuzzi better to use other construction materials with high water repellency characteristics.Especially not recommended for use in such spaces for drywall attachment headliner.Swollen, the material sags, deformed and could bring down the entire structure.
  • To build or finish the attic, utility extensions used fireproof plasterboard with a guaranteed resistance to high temperatures.

  • purchasing sheets, make sure that the marking on each unit.Plant material is labeled blue.If the surface is no inscription or she made a faint pencil, discard the product.Most likely, he is released without complying with the guests who are not certified or made of poor quality.
  • caulking at the joint follow special ready solution, designed for interior use in residential areas.Otherwise, get a source of emissions of harmful substances in the complete safety of drywall.
  • to seam seal the best material acts elastic putty.It prevents the occurrence of defective part in the design by changing the temperature conditions, and thus eliminates the possibility of the formation of mycotoxins.
  • carefully closing up the seam, provide sound insulation, remove the source of moisture penetration into the weld joints and prevent fungal infection base.
  • Technical drywall has an appearance similar to the usual dry plaster.The difference between the core sheets.For technical product used plaster poor handling.microscopic surface sheet dissipates dust into the air.The constant presence in the room, decorated in such material contributes to an allergic reaction, redness of the eyelids, nasal congestion.Use this type of drywall is recommended in non-residential rooms.

  • in a well ventilated area gypsum board serves as a moisture regulator.The porous surface absorbs excess moisture and starts to produce water vapor into the environment when changing the composition of the air.Plan a good ventilation system and drywall will serve not only for decoration, but also for the natural moisture or dry.
  • performing the installation of partitions, doorways, arches made of plasterboard, carefully select the dye surface.It must match the specifications of dry plaster, not to change its porous structure.

Plasterboard harm and benefit

analyzing the above information, the conclusion of harmlessness for finishing drywall home, hozpristroyki, office or public institutions.The main thing is to follow the recommendations of use of the material.Check the quality of the building material prior to the acquisition:

  1. Ensure that the gypsum layer is white, no gray inclusions.Ask
  2. check sheet to break.Bend and make an incision on the product line.A quality drywall breaks down strictly on blueprint, the edges are not broken, jagged peaks.
  3. sheet with peeling cardboard surfaces indicate a low-quality product.
