“If a car, then Mercedes, if a heater, then Ursa (URSA)” - and this statement really takes place. Founded in 2002, the brand under the Spanish-German foundation has proved to everyone who is in charge here.
According to a study by Global Research & Data Services "Insulation" in 2010, the company was the leader in the Russian market for the manufacture of fiberglass products.
It is enough to go to any hardware store and our hero will certainly be among the eminent manufacturers. Why is URSA mineral wool so good? Specifications will show a clear answer to this question.
Features of Ursa material
Insulation Ursa based on fiberglass
Universal insulation Ursa effectively reduces heat loss and creates a comfortable indoor climate. Low specific gravity helps to reduce the volume of building materials, energy consumption.
The URSA trademark produces 2 types of products:
- thermal insulation based on Ursa expanded polystyrene (EPS);
- based on fiberglass.
The first category includes material made by extrusion technology. The foam particles are combined with the foam under pressure and heat. The hot mass passes through the extrusion head of the unit and Ursa extruded polystyrene foam is obtained.
The second category is insulated by combining dolomites, quartz sand and soda. Substances melt, additives are placed in the mass for gluing the components. The hot composition is forced through the nozzles of the extrusion unit.
Technical characteristics of mineral insulation
Indicators of density and size of roll insulation and Ursa boards
The category of mineral insulation includes materials made from natural constituents such as fiberglass. Products are sold in slabs or rolls. The structure does not include phenolic substances for linking ingredients, therefore Ursa mineral wool is an environmentally friendly product.
The composition contains sand, soda, and other non-combustible materials, therefore, the insulation is characterized by increased fire safety indicators. The manufacturer indicates a period of 40-50 years of operation without destruction and loss of quality.
Insulation density
The density of a material is determined by the ratio of weight to volume. For glass wool, the indicator is determined on a scale of 15-85 kg / m3, depending on this, the scope of use is selected. In private houses, a material with an index of up to 30 kg / m3 is used, and industrial insulation requires a foam of a higher density.
Specific thermal conductivity
The characteristic shows the ability of roll and board materials to conduct heat from heated to cold layers. The transfer of energy occurs due to the movement of elementary particles in the composition of the insulation. Ursa mineral wool has a low ability to transfer heat, therefore, good insulation of structures and pipelines is obtained.
The lower the coefficient of thermal conductivity, the better the protection against cold. For mineral wool, the indicator is within the range of 0.031-0.045 W / mK. This amount of energy passes through the thickness, which indicates the high thermal insulation properties of the interlayer.
Temperature range of application
Flammability and thermal conductivity specifications
The characteristic defines the temperature range at which the insulation retains the specified properties. The manufacturer guarantees that Ursa polystyrene does not change the declared qualities at ambient temperatures down to -60˚С. The upper figure is + 310˚С.
These indicators apply only to the atmosphere, because.the surface of the insulation can withstand other temperature loads, the limit of which is + 100˚C, and some categories retain their properties at + 180˚C. The insulation belongs to a universal class and is suitable for protecting various structural elements from the cold in any climatic conditions.
The material is marketed in the form of rolls or slabs. Roll products are produced with a thickness of 5-20 cm, the width varies in the range of 60-120 cm. The length of the mats is 3-18 m, and the sheets are produced in the size of 1.25 m.

All these firms can be compared with each other by density insulation. The densest are Ekovata and Ursa. Rockwool and Izomin have an average density, and the Park insulation is the least dense. The next comparative property is the environmental friendliness of the insulation composition. The most safe are: Izomin, Ursa, Knauf, Rockwool and Ekovata. They do not rot, burn, and do not emit harmful substances. You can also compare according to the possible area of application. If the insulation is lightweight, then it can be used to insulate the room from the inside - these are Park and Krauf. Insulation with more heavy weight can be mounted on facades, these are: Rockwool, Ursa, Izomin.
Line of materials based on EPS
The materials have a low thermal conductivity (0.028-0.035 W / mK), have increased strength and low specific gravity (45 kg / m³), which reduces the weight of the structure.Extruded polystyrene foam is characterized by closed cells in the structure, the diameter of which does not exceed 0.2 mm. This structure provides moisture resistance in damp conditions.
URSA XPS

Main advantages
The service life without loss of properties is comparable to the operating time of the structures, the insulator ages simultaneously with them and does not require replacement. The high tensile strength of extruded polystyrene foam is its positive quality, due to which the material performs protective functions and works as additional structural elements that can withstand some loads.
When cutting, the fiberglass crumbles, so you need to work with gloves and a mask
Advantages of Ursa materials:
- ecological cleanliness;
- increased soundproofing qualities;
- long term of work;
- resistance to temperature shocks;
- wide range of applications;
- elasticity and firmness;
- fire resistance;
- ease;

- not subject to decomposition and decay.
There are some downsides to use. For example, mineral wool decomposes on direct contact with alkalis, and fine fibers fall out of glass wool during the cutting process.
Applications
Ursa slab insulation can be used as a substrate for asphalt
Universal thermal insulation Ursa is used in the process of any construction. The versatile characteristics allow the protection to be used for difficult curved surfaces.

Reliable thermal insulation is established with a minimum thickness that is comparable to thicker layers of other materials. Internal insulation made of Ursa material does not reduce the horizontal and vertical dimensions of the room.
Ursa Pureone - sustainability
Snow-white mineral wool, distinguished by a special production technology. The main advantage is the absolute safety of use. Its use is permitted in institutions with high sanitary and hygienic requirements: kindergartens, hospitals.
Material composition and characteristics
It was possible to achieve such qualities due to rejection of binders made from phenols, formaldehyde resins, recycled products... They were replaced with acrylic. The component is an organic compound, it is harmless to the environment, people, animals. The bright whiteness of Ursa Pureone products is the result of the combination of fused silica and acrylic. Additional dyes are not used in production.
Useful: Tool for building a frame house
Performance properties of Pureone line heaters:
- thermal conductivity - 0.34-0.37 W / m * ° С;
- vapor permeability - 0.51 mg / m * h * Pa;
- water absorption - 1 kg / sq. m in 24 hours;
- flammability level - NG.
Variety of product line
The company offers three options for thermal insulation mats:
- Ursa Pureone 34. From the presented model range it is distinguished by the highest class of sound insulation. High technical parameters, including thermal efficiency, make the material in demand in various fields. Insulation is used when finishing noise-absorbing structures, assembling various types of transport, creating acoustic ceilings, as external insulation of walls, attics.
- Ursa Pureone 35. In terms of properties, it is almost identical to the previous position. An additional plus - increased elasticity due to the "elastic felt". Release form - slabs in a roll.
- Ursa Pureone 37 RN. Insulation is produced in the form of elongated mats. Insulation thickness - 50/100 mm, width - 60 cm, length - 125 cm. The increased dimensions make it easier and faster to install the heat insulator on large areas.
