"Ursa" (insulation): characteristics and reviews

Heaters produced by Ursa (a subsidiary of URALITA concern) are at the moment extremely popular and in demand both for private homeowners and for large construction companies. This is explained by their remarkable performance and long life.

Where are the materials from Ursa used?

"Ursa" is a heater used not only for buildings, but also for the assembly of water pipes, heating systems, other communications, as well as for the construction of roads, bridges, aerodrome runways and in many other areas. In each case, the types of this insulation are used, the technical characteristics of which are as precise as possible for this particular purpose. Next, consider what types of this material actually are produced by the company at the moment.

Varieties of materials "Ursa"

The company Ursa presents to the attention of the Russian consumer just a huge number of different heaters, the main characteristic of which is more than excellent quality. All these varieties can be combined into two large groups - fiberglass materials and extruded polystyrene foam. Both are equally in demand in the Russian market.

Method for manufacturing fiberglass varieties

Insulation for walls "Ursa", as well as materials intended for insulation of floors, ceilings, roofs, etc., are made of a mixture of soda, sand and dolomites. The latter melts under the influence of very high temperatures. Long fibers are drawn from the resulting mass, from which mats or plates are made. Bonding of glass "threads" in a single fabric is made using environmentally friendly binders.

Advantages and disadvantages of fiberglass materials

This is the most popular variety, especially in the owners of suburban areas, building on their houses. The main advantages are:

• Very low coefficient of thermal conductivity - 0.032-0.046 W. For comparison, this index varies from 0.037 to 0.005 W for the same foam.
• Convenient dimensions. Glass-fiber insulation «Ursa» are produced both in mats and plates. In the first case, the most popular variety is the roll insulation "Ursa", the dimensions of which are 1200 * 4200 mm, and the thickness is 150 mm. The standard size between roof rafters and frame racks is 60 cm. In this case, the canvas is simply cut in half along. If the step between the elements is different, it is cut across, measuring the necessary distance along the length.
• Environmental Safety. In the production of some varieties, formaldehyde-containing materials are not used.
• Easy to install. Unlike many other, cheaper types of glass wool, "Ursa" has a very strong structure, and therefore, it is very difficult to break it.
• Fire resistance. Steklovata "Ursa" does not burn at all.
• Durability. This heater can withstand temperature changes from -60 to +220 g. He serves about 50 years.

"Ursa" - insulation, to the disadvantages of which can only be attributed to the relatively high cost.

Varieties of fiberglass "Ursa"

Thermal insulators of this brand are divided by density, degree of heat conductivity and application area into several main classes:

• URSA Geo. It is used for heat insulation of pipelines and sewer pipes. However, most often it is used in private and industrial housing construction for insulation from the cold of walls, floors, ceilings and roofs. Among the owners of countryside sites, the most popular is the "Ursa" M 11 insulation, which, among other things, can be used on the floor and in the interstorey floors. These are mini-plates of universal purpose. Type "Light" is intended primarily to cover unloaded structures - roofs and walls. Also in the URSA Geo line are sound-proof varieties intended for rooms with high humidity, for pipes, false floors, etc.
• PureOn. This variety consists of 95% natural components. At the same time, by the softness and fineness of the fiber, it is not inferior to cotton wool.
• TERRA. These are slabs of increased density of small dimensions, very convenient for use in private housing construction.

Glass-fiber insulation «Ursa»: reviews

The opinions of those who have already managed to use this kind of insulation, it is mostly more than positive. In particular, owners of country houses like that when installing plates and sheets, there is practically no harmful glass dust. Also, private developers like the fact that the "Ursa" material, unlike ordinary glass wool, does not crumple and does not lose shape. It is also noted that when working with slabs and mats, the pieces do not come off the canvas.

Those homeowners who have small children, very much praise a variety of PureOn, because it completely lacks phenol and other poisons. Heater "Ursa", reviews about which are only positive, for everything else, very easily cut.

Plates from extruded polystyrene foam

This kind of insulation "Ursa" also enjoys well deserved popularity with private developers and large construction companies. Most often, polystyrene plates of this brand are used to warm the foundations of buildings and structures. The fact is that they are absolutely not afraid of moisture and the impact of all sorts of aggressive chemical elements that exist in any soil. Mounting plates "Ursa" can be done absolutely without any additional protective material.

Advantages and disadvantages of expanded polystyrene plates from Ursa

"Ursa" is a heater, to the merits of which it is possible to attribute:

• Increased strength. Plates do not break and are capable of withstanding significant compression loads.
• Non-exposure to putrefaction. Styrofoam insulation "Ursa" is not affected by fungus and insects.
• The ability to effectively perform its function at temperatures from -50 to +75 g.
• Long service life - more than 50 years.
• Low coefficient of thermal conductivity - from 0.032 to 0.034 W. Thanks to this, when using this material, the heat loss in the building during the winter period is significantly reduced.
• Flexibility. Such slabs can be laid directly on the sand cushion without the need to give it additional rigidity.
• High density - from 35 to 40 kg per m ³ .
• Easy installation. You can cut slabs with a conventional knife. Many types of plates have a system of spike-grooves, to all the rest, allowing to avoid the appearance of cold bridges in the heat-shielding layer. This also greatly facilitates the installation of slabs.

The disadvantages of this variety can also be attributed to the high cost. Ursa foam polystyrene plates can not be mounted on wet surfaces. They must first be carefully dried. The fact is that "Ursa" - foam polystyrene insulation - is itself a vapor barrier, and therefore the wet structural elements under it will not dry out and will start to deteriorate.

Ursa insulation products from extruded polystyrene foam are represented on the Russian market by the only URSA XPS line. The standard sheet size is 1200 * 600 mm.

Opinion of consumers about expanded polystyrenes "Ursa"

As well as the glass wool of this brand, there are only positive responses about the polystyrene insulation of Ursa. For example, those homeowners who replaced with this material the previously used foam, note that the premises became much warmer. With the use of insulation "Ursa" can significantly save on electricity. Even in very cold weather, the walls of the houses, which were lined with it, remain very warm. A very good opinion exists in the consumer about a material such as insulation "Ursa" 50mm. It is not particularly expensive and is often used for warming foundations.

At installation there is no harmful dust, besides the heaters of this brand to everything else, being installed from inside the premises, are absolutely not afraid of condensate.

Cost of Ursa materials

The price for heaters of this brand depends solely on the variety. The cheapest is "Geo" heater "Ursa". The price for it is about 900 rubles per cubic meter. But in this case the cost also depends on the type. The above price is valid for the "Light" heater. The most expensive material of the line "Geo" - P-60 costs 4600 rubles per cubic meter.

The insulation of PureOne can be purchased at a price of 1500-1600 rubles per cubic meter. Expanded polystyrene version is about 3500-5500 rubles per m ³ .

As you can see, the insulation of "Ursa", the price for which is quite high, differs in fact, just excellent performance characteristics. Spent money in any case will not be lost.
