Probkovyiy an oak cut as a sheep

Until recently the stopper associated at us exclusively with production industry wine-vodka. However materials from a bark of a pith oak are also excellent materials for processing. Materials for processing from a stopper have good warmly - and sound-proof qualities, and also fine acoustic properties. The walls which have been pasted over with a stopper, eliminate an echo and reduce noise between rooms on 17-20 dB. Any version of a stopper is characterised by the lowest heat conductivity, stability to differences of temperatures, changes Read more

Kak to force music to "sound"

Creation of good acoustics of a premise — one of conditio sine qua nons of qualitative functioning modern High end a stereosystem or a house cinema. However frequently the premise choice is made disregarding acoustic specificity of a premise. And the equipment choice becomes the first and unique step. As to acoustic registration of a premise the given question arises, as a rule, at the last stage of painting and decorating after experts in equipment installation express concern in an end result — quality of sounding in the given Read more

CHtobyi ears have not got tired

Sound and noise isolation are a component of protection against negative effect of environment. In many countries in a legislative order as much as possible admissible noise level in many areas of our life is already established. However there are still areas (for example, road and transport movement) which wait for the turn.

Sound insulation is necessary, as intensive acoustic effect is dangerous to all live. People are often treated to action of noise of the house, in the street, on work, during rest. As a result they become aggr Read more

Kak to be pulled out from a noise captivity

The correct choice of a necessary sound-proof material depends on a kind of noise, its level and the frequency characteristic, and also from maximum permissible levels (PDU), established for various premises. So, PDU for industrial premises with speech communication are established in limits — 80-85 dB, in administrative premises — 13-51 dB.

The physical characteristic of level of a sound is its force in decibels (1db = 1 erg / sq. sm*s=10 **-7 vt / sq.), representing the quantity of energy which is carried by by a wave Read more

Goryi turn in minvatu

Mineralnaya cotton wool is the fibrous material received from silicate rasplavov of rocks, metallurgical slags and their mixes.

Leading world manufacturers mineralovatnoy production as raw materials use exclusively rocks that allows to receive mineral cotton wool of a choice quality with a long economic life. Such material is recommended to be applied to responsible designs — in a case when long-term reliable work of the given structures is required. The mineral cotton wool received from domain slags, has no sufficient durability i Read more

Uteplitsya and not to be mistaken

The more thermoresistance of a material of which the house is constructed, the it is warmer. The tree in many times surpasses on teploizolyatsionnyim to properties a brick. The brick wall in the thickness of 510 mm (in two bricks) has almost same thermoresistance, as well as a wall from a wooden bar in the thickness of 100 mm.

The tree good teploizolyatsionnyie qualities, but all the same has enough of it for effective warming of the house. Traditional construction materials (ferro-concrete, a brick, a tree) are not capable to supply Read more

Ukryitsya polyfoam from a frost

Expanded polystyrene — ecologically pure, nontoxical warmly - and the sound-proof material applied in building throughout already 40 years and proved as most economic, convenient in application and having the most economic, high degree convenient in application of heat conductivity and paropronitsaemosti.

According to the provided norms to a building thermal protection the wall from expanded polystyrene in 12 sm on the teplosberegayuschim is equivalent in the thickness of all to properties:

Bumaga will warm vas

Do this time at the Russian builder a choice of a material for warming of a cottage, a shed or garage was insignificant. Sawdust decays, polyfoam will not rescue from a fire, with glass wool itself to communicate will not want. Occurrence in Russia «EKOVATYI», undoubtedly, will please the zealous owner. Ecologically pure, stable against fire, unreceptive to rotting and a mould, convenient in work and inexpensive «EKOVATA» keeps few chances to the competitors — to traditional heaters. Cellulose cotton wool is obliged by the unusual propert Read more
