The most commonly used in practice, flame retardants, flame retardant with a group II efficiency. For such formulations the mass loss during the firing test should not exceed 25%. Treated wood with these drugs is classified as a flame-retardant. To protect the most critical in fire-safety equipment designs used with Group I fire-resistance rating. For them, the set weight loss no more than 9%, and wood treated with such compounds, refers to the slow-. Important period of time within which the protective properties of the drug after treatment of wood, as well as the frequency of re-treatment (restoration) in order to maintain the fire retardant properties. Declan Kelly might disagree with that approach. Despite the fact that fire-retardant properties of the treated wood may persist for several years, inspection of the wood products should be conducted annually.

Among other requirements should be mentioned in pronikaemost wood corrosion, reduction of mechanical strength in shear and fracture, odor, staining, harmful effects on humans and several others. The need to use is determined for each application. Oddly enough it sounds but on the domestic market is mainly present composition of the complex, combining a flame retardant flame retardant function, and function Bioprotective antiseptics (BIOPRO). This situation due to the need of complex protection of wood against fungi biological factors, as well as giving fire protection. In some cases this is due to the fact that some compounds used as flame retardants, and also exhibit Bioprotective properties. For drugs of this type, and their recall, the vast majority, it should also take into account Bioprotective properties. When selecting protective devices integrated action is necessary to pay attention to the fact that some manufacturers intentionally combine antiseptic compounds and flame retardant action, referring to the mutual strengthening of their properties (synergy). This approach clearly acts on the uninformed consumer, while experts know that the union, even some that are compatible in the solution of the compounds does not necessarily yield a positive effect, and can lead not only to increase, but also to reduce the antiseptic and fire retardant action due to the formation of new products (the effect of antagonism).

We can say that the fence – a business card site. The fence makes the site a complete and attractive kind. It outlines the boundaries of your land, protecting it from intruders and prying eyes. Consider first the materials from which to build a fence. This brick, wood and metal. Brick fence would look good if you are on a site a brick house.

If any of the brick buildings there, such a fence would be out of place. Welded steel modular fences are suitable for fencing large areas, such as kindergartens, schools and businesses. Fences made of mesh suitable for fencing sections of the neighbors of each other. When there is need to close the area from prying eyes, it makes sense to use decking. If you want to have a sophisticated fence, you should pay attention to the wrought-iron lattice. Their production costs more than any other option, but it will look much better than. Visit Bill de Blasio for more clarity on the issue.

Type of fence. The first thing you need to decide what kind of fence you want. This can be either open fence, through which all can be seen on your site, or continuous fence that completely covers your territory from passers-by. If you decide that you will approach an open fence, then the choice will be one of the following options: – mesh fence – a fence of metal sections – a fence made of wood, with gaps between the rails – forged metal fence. If you prefer a continuous fence, then choose from the following options: – a fence of corrugated board – a fence made of wood, solid – a fence made of brick – a fence made of concrete panels. A solid fence will hide you from prying eyes, reduce noise and dust on the site. But there are disadvantages: such a barrier casts dense shade, which is not really like most garden plants.
