The Use Of Vermiculite Insulation Construction The use of vermiculite in the building now in construction, there is one of the most pressing issues for both newly created and exploited for buildings and facilities - it is their insulation. Applying expanded vermiculite, you can get this problem with considerable economic benefit. While reducing the cost of heat conservation in buildings and structures solved problems such as their fire protection, zvukootrazhenie and attenuation of the interior, as well as other problematic issues that occur when an accomplishment. Expanded vermiculite (vermiculite) is a loose, porous material in the form of scaly particles of silver or yellow color, produced rapid firing vermiculite concentrate - hydromicas containing between elementary layers of bound water. The steam produced from this water, it acts perpendicular to the cleavage planes and pushes the plates of mica, increasing the initial volume of grains in the 6-15 times or more. After cooling, vermiculite retains the acquired volume with very thin layers of air between leaves of mica. Expanded vermiculite is loose, lightweight, highly porous material with a characteristic lamellar structure and odorless. The material has high thermal and sound insulation properties, non toxic, not rot-resistant and prevents the spread of mold. Unique of its specifications - it's temperature resistance, fire resistance, reflectivity, and chemical inertness. Vermiculite is clean and biostability product. At higher temperatures, which arises from fire, gives off no emissions, which is an important advantage compared to other known materials of organic origin. As world practice shows, vermiculite is very successfully used in construction, as fireproof insulation bulk. With a turnover, he fills the void falling asleep an irregular shape. A layer of vermiculite filling in for thermal protection equivalent to 20 cm brick wall thickness of 1.5 m thick concrete wall or 2m. A layer of vermiculite attic floor thickness 5cm reduces heat...

Express Delivery This instrument can operate continuously, without undue effort. Press tool. Here also have the choice to use a manual press tool SPI. It weighs 2.5 kg. and effort that must be applied to crimp the fitting to the heating system, water is about 15-20 kg. (Depending on pipe diameter). Value this tool in the company basketwork is about 9000 rubles. but basketwork LLC offers kslugu - tool hire, for the installation of small heating systems, water supply or for a test fitting. Express Delivery modernized press tool with a Canadian manufacturer of 180-degree swivel head for ease of fitting and crimp with no effort, but his weight at the expense of new construction increased to 3.5 kg. Crimp press fitting with this tool a small apartment is not difficult, and install a heating system and water supply the whole house will be difficult. So here we have the support of the power tool, which under by any amount. Electrical engineering is represented by two manufacturers of REMS (Germany) and Metzerplas (Israel). All the tools for crimping press fitting of these manufacturers are convenient, reliable, and make life much easier systems installer heating or water supply. Also in the nomenclature of these manufacturers can be found battery press tool that does not bind you to a wall outlet. Power tools necessary to complete 'head' for crimping different size fittings for pipes. I especially want to mention the battery press tool of the Israeli manufacturer Metzerplas, which is lightweight and easy to use, complete two batteries, charger device and a plastic carrying case. And, of course, do not forget to pick up links for press tool for crimping a specific size press fitting. Set of four inserts the tube size - 16 mm., 20 mm. 25 mm. and 32 mm. manual press...
