Dowel suitable for foam - features and tips on choosing

As during the construction itself, and in the further finishing and maintenance of any building have something to attach to the walls - elements of engineering communications, household appliances, furniture items and the like.This process of "chipping - Drilling" is familiar to every man.There are many ways to fix a variety of products on the surface, and of course, for this purpose, a variety of fasteners.

But when it comes to buildings of blocks, there are certain difficulties.The reason - the high porosity of the aerated concrete, which does not work with any fasteners.By the way, experts such characteristic foam is considered one of his "cons".And at the same time it is so popular material for the construction of the budget that we have to work with many of them.How to be?

order to securely fasten anything on the blocks, you need to use only special plugs for foam.They are manufactured or made of metal, or of plastic (usually nylon).The material they are "drives" in two ways - by screwing or "landing" in the pre-drilled hole.

Metal

used when provided increased load on the fastener, or if it is stipulated fire safety requirements.In the "body" are spacer segments (4 pieces), providing rigid fixation at the place of installation.On the outside of the many special dowels are located projections (teeth), providing a more reliable "coupling" with the wall material.

Plastic

considered universal, as are applied universally, if the "hung" (attachable) structure does not have too much weight, or is not subjected to excessive mechanical stress.At home dowels are used most frequently with diameters ranging from 4 mm to 12 mm.They can screw almost any metiz - screw, screw, screw.

products that are installed by screwing in the foam, are on the surface of the characteristic thread.The length of the dowels is in the range from 3 to 6 cm. Sale or come in packs (20, 25, 50, 100 pieces), or "bulk" and sold individually.

If we talk about the cost of the anchors, the cheapest, of course, nylon.Is available for sale such products usually sets in their original packaging.The price depends on two parameters - the length and diameter.But it still has its own set for each region.

example, products "Sormat" will cost 160 rubles / pack.(4 or 6 mm -25 pcs.).The same dowel 8 mm sold for 250 rubles / pack, 10 mm -. 490 rubles / pack.

Metal products are more expensive.6 mm in diameter - about 1 250 rubles, 8 mm - 1 580 rubles, 10 mm - 1790 rubles (25 pieces packaging).

should also be said about such a product as dyubel- "nail".It is used not often, as is suitable for mounting only on the objects with a high density blocks.On average, the cost - 75 rubles (package 50 pieces).

Tips for Choosing

• Construction ventfasada, exterior finish - for the job is recommended to use metal dowels.For example, a professional hardware brand «SHR».
• Dyubel- "nail" applies only to placement of relatively light objects - painting, wall lamp, and the like.
• should buy Anchor «GB» type for mounting massive products or suffer from increased load.Plug in such cases is less reliable.

In other cases, the use of plastic products is enough.
