Heaters manufactured by Ursa (a subsidiary of the URALITA concern) are currently extremely popular and in demand by both private homeowners and large construction companies. This is explained by their remarkable performance and long service life.
Where are Ursa materials used?
Ursa is a heater that is used not only in the construction of buildings, but also in the assembly of water supply systems, heating systems, other communications, as well as in the construction of roads, bridges, runways of airfields and in many other areas. In each case, varieties of this insulation are used, the technical characteristics of which correspond as closely as possible to this particular goal. Next, we will consider what types of this material are currently being produced by the company.
Varieties of materials "Ursa"
The Ursa company presents to the attention of the Russian consumer just a huge number of a variety of heaters, the main characteristic of which is more than excellent quality. All of these varieties can be combined into two large groups - fiberglass materials and extruded polystyrene foam. Both those and others are equally demanded in the Russian market.
The method of manufacturing a fiberglass variety
The insulation for Ursa walls, as well as materials intended for insulation of floors, ceilings, roofs, etc., are made from 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 boards are made. Bonding glass "threads" in a single cloth is made using environmentally friendly binders.
Advantages and disadvantages of fiberglass materials
This is the most popular variety, especially among owners of suburban plots building houses on them. Their main advantages include:
- Very low coefficient of thermal conductivity - 0.032-0.046 watts. For comparison - for the same foam, this indicator varies from 0.037 to 0.005 watts.
- Convenient sizes. Ursa fiberglass insulation is available both in mats and slabs. In the first case, the most popular variety is Ursa coil insulation, the dimensions of which are 1200 * 4200 mm and a thickness of 150 mm. The standard size between the roof rafters and the racks of the frames of houses is 60 cm. In this case, the canvas is simply cut in half lengthwise. 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 of 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. Glass wool "Ursa" does not burn at all.
- Durability. This insulation can withstand temperature extremes from -60 to +220 gr. He has been serving for about 50 years.
"Ursa" is a heater, the disadvantages of which include only a relatively high cost.
Varieties of fiberglass "Ursa"
Thermal insulators of this brand are divided according to density, degree of thermal conductivity and field of application into several main classes:
- URSA Geo. It is used for thermal insulation of pipelines and sewer pipes. However, most often it is used in private and industrial housing construction to isolate walls, floors, ceilings and roofs from the cold. The most popular among owners of suburban areas is Ursa M 11 insulation, which, among other things, can be used on the floor and in floors. These are universal mini-cookers. The “Light” type is intended mainly for covering unloaded structures - roofs and walls. Also in the URSA Geo line are soundproof varieties intended for rooms with high humidity, for pipes, raised floors, etc.
- PureOn. This variety is 95% natural. At the same time, it is not inferior to cotton wool in softness and fineness of fiber.
- TERRA. These are high-density plates of small sizes, very convenient for use in private housing construction.
Fiberglass insulation "Ursa": reviews
The opinions of those who have already managed to use this kind of insulation about it are mostly more than positive. In particular, the owners of country houses like the fact that during the installation of plates and sheets there is practically no glass dust harmful to health. Private developers also like the fact that the Ursa material, unlike ordinary glass wool, does not crease and does not lose shape. It is also noted that when working with plates and mats, pieces do not come off the canvas.
Those homeowners who have small children greatly praise the PureOn variety, as it lacks phenol and other poisons. Ursa insulation, reviews of which are only positive, is also very easy to cut.
Extruded polystyrene boards
This type of insulation “Ursa” is also quite deservedly popular among private developers and large construction companies. Most often, polystyrene boards of this brand are used to warm the foundations of buildings and structures. The fact is that they are completely not afraid of moisture and the effects of various kinds of aggressive chemical elements found in any soil. Ursa slabs can be mounted completely without any additional protective material.
Advantages and disadvantages of polystyrene boards from Ursa
"Ursa" - a heater, the advantages of which include:
- The increased durability. Plates do not break and are able to withstand significant compression loads.
- Intolerance to decay. Expanded polystyrene insulation “Ursa” is not affected by fungus and insects.
- The ability to effectively fulfill its purpose at temperatures from -50 to +75 gr.
- Long service life - more than 50 years.
- Low coefficient of thermal conductivity - from 0.032 to 0.034 watts. Due to this, when using this material, heat loss in the building during the winter period is significantly reduced.
- Flexibility. Such plates can be laid directly on a sand cushion without the need for additional rigidity.
- High density - from 35 to 40 kg per m 3 .
- Easy to install. Plates can be cut with an ordinary knife. Many types of plates have a spike-groove system, among other things, to avoid the appearance of cold bridges in the heat-protective layer. It also greatly facilitates the installation of plates.
The disadvantages of this variety include the high cost. Ursa polystyrene boards cannot be mounted on wet surfaces. They must first be thoroughly dried. The fact is that Ursa, a polystyrene foam insulation, is itself a vapor barrier, and therefore wet structural elements under it will never dry out and begin to deteriorate.
Ursa extruded polystyrene insulation materials are presented on the Russian market by the only URSA XPS line. The standard sheet size is 1200 * 600 mm.
The opinion of consumers about polystyrene "Ursa"
Like the glass wool of this brand, there are only positive reviews about Ursa polystyrene insulation. For example, those homeowners who replaced the previously used polystyrene with this material note that the rooms have become much warmer. With the use of insulation "Ursa" you can significantly save on electricity. Even in very severe cold weather, the walls of the houses sheathed by him remain very warm. A very good opinion exists among the consumer about such a material as Ursa insulation 50mm. It is not particularly expensive and is often used to warm foundations.
During installation, no harmful dust appears, in addition, heaters of this brand, among other things, being installed inside the premises, are not at all afraid of condensation.
The cost of materials "Ursa"
The price of heaters of this brand depends solely on the variety. The cheapest is "Geo" insulation "Ursa". The price for it is about 900 rubles per cubic meter. But in this case, the cost also depends on the type. The price indicated above is valid for “Light” insulation. The most expensive material of the Geo line - the P-60 costs 4,600 rubles per cubic meter.
PureOne insulation can be purchased at a price of 1500-1600 rubles per cubic meter. The polystyrene foam option costs about 3,500-5500 rubles per m 3 .
As you can see, Ursa insulation, the price of which is quite high, differs in fact by simply excellent operational characteristics. In any case, the money spent will not be wasted.
