URSA insulation

Quality insulation of your home is one of the most important tasks of any homeowner. Of course, with a diligent approach, the owner of the house will strive for high efficiency of thermal insulation, bearing in mind at the same time affordable prices for insulation materials, environmental and fire safety of the design. And to guarantee such a combination can only high-quality product of well-known manufacturers.

One of the most popular thermal insulation materials is mineral wool made from environmentally friendly natural raw materials. If to argue from the positions of value, then the most profitable is the use of mineral wool based on fiberglass. But here, however, about glass wool you can hear a lot of "negative" - ​​low stability, fragility, propensity to stall and loss of volume, wetting, etc. Perhaps all this is so, if you acquire the unknown material of an unknown producer. But everything is quite different when choosing a high-quality insulation Ursa technical characteristics of which will be discussed in detail in this publication.

A few words about the history of the brand URSA

logo of the brand «URSA» can not be confused with one another - a white bear silhouettes with bear. This is how the word "ursa" is translated literally from Latin. This trademark was officially registered not so long ago - in 2002, but the history of production of thermo-insulating and building materials of this company is much richer.

The origins should be sought at the beginning of the 20th century - in 1907 the Spanish entrepreneur José Roviiralta decided to organize the production of innovative materials for building fibrous cement at the time. It is interesting that mineral raw materials, delivered from Russia - from the Ural Mountains, were originally used as raw materials. This circumstance gave the name of the company - "URALITA", which in literal translation means "Ural stones".

The case, as they say, went, it began to expand, and pretty soon the products of "URALITA" became recognizable and very popular all over Europe, and the company "crossed borders" and became a transnational concern.

At the end of the last century, the concern included Pfleiderer and Poliglas, the leaders in the manufacture of thermo-insulating materials. On then it was decided to combine all the research and production facilities operating in the insulation materials sector under a single brand - and the "white bear" - "URSA"

was born. Nowadays, the products under the brand name "URSA" are producedat 14 enterprises located in different countries of Europe. Three powerful plants operate on the territory of Russia - in the city of Chudovo, Novgorod region, and the city of Serpukhov - Moscow.

It is interesting that the plant in Chudovo is the oldest branch in the whole structure of the concern "URALITA" - this enterprise, which earlier specialized in the production of glass, has been counting its history since 1876.Now it is a powerful, fully modernized enterprise that meets the strictest international standards of quality and environmental safety.

Product line «URSA»

The main product of the brand "URSA" is a mineral wool insulation based on fiberglass, manufactured according to a special technology developed by the company's specialists, which eliminates or minimizes the characteristic shortcomings of glass wool. However, the assortment of "URSA" is not limited to this - there are absolutely innovative developments of fibrous thermo-insulation materials "URSA PUREONE" and heaters based on the extruded polystyrene "URSA XPS".In addition, the release of special membrane coatings is required to create effective thermal insulation systems.

Thermal materials of the "URSA GEO" range

This is the most common material in the company's assortment. Its basis is glass fiber, made from purified quartz sand with mineral additives. The special eco-technology produced by GEO, the subtleties of which, of course, are a production secret, makes the products absolutely safe for humans and the environment - the canons of the modern approach to "green building" are observed.

• Although in the production of mineral wool heaters we can not do without organic binders yet, their emission in URSA GEO is reduced to almost zero, that is, the premises will maintain a clean and healthy atmosphere.
• The most important advantage of URSA GEO heaters is the non-flammability and high temperature resistance. The material not only does not ignite, but also prevents the spread of flame.
• The material has a pronounced biostability - it does not lend itself to scaling or rotting, does not serve as a nutrient medium for any forms of life.
• Convenient forms of release of URSA GEO line heaters significantly simplify the installation of thermal insulation structures. Despite the apparent fragility, fiberglass has excellent strength and elasticity. In some cases, the installation of insulation boards or mats does not require even an additional fixation.
• Thermal insulation "URSA GEO" stands out against the general background of increased durability - it does not fall down, does not lose form and performance characteristics, and can serve faithfully for at least 50 years.

In the assortment of "URSA GEO" - about 20 items. It makes sense to consider those that are most often used in individual construction.

• "URSA GEO M-11"

This type of insulation can be safely attributed to the most popular - it is highly versatile, and is used in virtually any area of ​​private construction to create thermal insulation or noise insulation:

-for the insulation of interfloor or attic floors on beams or lags.

- for the insulation of frame walls or the creation of soundproofed internal partitions.

- can be used as a heater in multi-layer brick or stone walls.

- excellent for warming of loggias and balconies.

- used for thermal insulation of pipelines or ventilation ducts.

Available in rolls of various lengths and widths - very convenient in self-assembly.

• "URSA GEO M-11 mini"

In the practice of private housing construction, there are often areas for insulation or noise insulation which is more convenient to use small format material. The manufacturer thought about this issue - "URSA GEO M-11 mini", being an analogue of the above-presented type, is produced in the form of narrow mats, rolled into rolls. This greatly simplifies the transportation of material on personal transport, and the conduct of independent installation work.

• «URSA GEO Private house»

The name of the species speaks for itself - it is a product of increased versatility, designed specifically for use in individual construction or for insulation of apartments.

Excellent for thermal insulation of beams or joists, for thermal insulation of frame walls, for the construction of internal light partitions with the required level of noise insulation.

Convenient packaging of material - it is designed for 20 m², which facilitates the calculation when planning construction or repair work.

• «URSA GEO Light»

If the owners are primarily interested in the economics of thermal or noise insulation works, then we can stop on the "lightweight" version of the insulation - "URSA GEO Light".

This material also has versatility - it can be used in horizontal unloaded insulation constructions( floors and ceilings on beams and lags), as well as for acoustic ceilings and interior partitions.

• «URSA GEO Pitched roof»

The material of specific designation was created specifically for the insulation of pitched roofing structures. At the same time, it provides reliable roof insulation and highly effective protection against external noise, which is especially important for mansard living quarters.

This type of production uses a special technology - "URSA Spannfilz", which can be translated as "elastic felt".The slabs have a pronounced elasticity and excel between the rafter legs, thus ensuring a good fixation, and the absence of "cold bridges".

Interesting and the form of release - plates in a roll. This makes it possible to easily cut material in any direction, minimizing waste at non-standard distances between the rafters.

• «URSA GEO Universal plates»

In some cases for conventional insulation work in a house or apartment it is more convenient not to use roll mats, but separate slabs. This is also provided in the product line - you can buy universal plates.

The main purpose of this material is the insulation of wall structures and the creation of soundproof partitions. However, they are not for nothing called universal - the plates are quite suitable for thermal insulation of floors, pitched roofs, cold floors on logs, balconies and loggias.

Convenient length and width of plates( 600 × 1000 mm) will greatly facilitate their installation in conditions, for example, a tight room or a limited working space.

• «URSA GEO Noise protection»

A special type of material, intended primarily for use in the construction of internal frame partitions. It has pronounced sound-absorbing properties( sound absorption according to class B).The special size of the roll( width - 610 mm) is calculated for installation between the frame guides located with a standard step of 600 mm.

However, these mats can also be used for insulation and noise insulation of ceilings, creating acoustic ceilings.

• «URSA GEO Frame»

The main purpose of this variety is the thermal insulation of structures on a metal or wooden frame. The range of thicknesses - from 100 to 200 mm allows effectively to warm the walls when erecting so popular in our time frame houses.

Designed mainly for vertical wall structures. The material has a high degree of elasticity( thanks to the already mentioned technology "URSA Spannfilz"), which ensures the stability of the thermal insulation layer and the absence of "cold bridges".It can also be used as a warming middle layer for "wells", for the insulation of roofs and ceilings over lags or beams. Can be used to create a warmed ventilated facade, but with the mandatory application of a windproof vapor permeable membrane.

Plates based on fiberglass, designed exclusively for external insulation of walls using "ventilated facade" technology. They have increased strength and dimensional stability. On the outside, they are covered with black glass fiber of high density and strength, which makes unnecessary use of additional wind protection.

If the insulation of the facade is planned two-layer, then such slabs are used for the outer layer.

• «URSA GEO M-11F»

A special kind of insulation mats specially designed for thermal insulation of rooms with high humidity( for example, baths or saunas).

On the outside, it has an aluminum foil coating. This layer creates a reflective screen that redirects the heat flow to the side of the room, and at the same time it becomes effective barriers preventing the penetration of steam into the thickness of the material. Thus, with internal insulation, there is no need to use additional vapor barrier membranes, which greatly simplifies installation.

Scope of application - thermal insulation of walls and ceilings in baths and saunas, but it can also be used in other insulation constructions inside the building.

Below in the table the main parameters of the mentioned URSA GEO heaters are listed. Thermal conductivity values ​​are indicated for temperatures of +10 and +25 ° C, as well as for normal( mode A) and wet( mode B) conditions of daily operation.

Insulating materials of the "URSA TERRA" line

A special type of thermal insulation materials of the brand "URSA" is the insulation of the "TERRA" line.

A special technology for their production implies the inclusion of additional mineral components in the quartz melt. The main thrust of such changes is an increase in the strength and elasticity of the material, its pronounced hydrophobicity. At the same time, higher thermal insulation characteristics were achieved.

The increased rigidity and elasticity of "URSA TERRA" heaters, while maintaining their inherent elasticity, simplifies the installation of thermal insulation structures on surfaces of complex geometric shapes or in pronounced irregularities.

Special treatment of the material gives it special hydrophobic properties - drops of water roll down the surface, not penetrating into the interior of the heater.

In order to visually isolate the materials of the URSA TERRA line, they are given a special exterior color - greyish-greenish color.

The assortment range is represented by three types of material:

• "URSA TERRA 34 PN"

The material is available in the form of plates with a convenient width of 600 mm, which simplifies their installation.

The main scope of application is external insulation of facades along the frame with subsequent siding of the walls. Can be used for frame walls, for ventilated facade systems with fixing of the finishing lining on the brackets. Successfully applied for brick multilayer walls, made on the principle of "wellwork" with an internal insulation layer.

It is not excluded to use floors and ceilings for thermal insulation on beams or lags, for warming a sloping roof with the placement of slabs between the rafters and a continuous layer under them.

Refers to the category of professional insulation materials.

• «URSA TERRA 34 RN Technical mat»

This is the optimal solution for technical thermal insulation. Due to its elasticity and flexibility, the mat will take any curvilinear position, ensuring that it is fully adhered to the surface. This quality makes it possible to use such mats for insulation of pipelines of any diameter, ventilation boxes, tanks, hydro and heat accumulators, various technological equipment.

A low mass of insulation will not have a significant weight load on pipes or ventilation ducts. Neighboring mats perfectly fit together, without requiring a particularly accurate fit.

• «URSA TERRA 34 PN Noise protection»

Elastic and elastic plates of this type are probably the most optimal solution in terms of providing noise insulation when building internal partitions. Their thoughtful width of 610 mm is specially designed for a tight installation between the guides of the standard frame construction.

The tests show that the installation of URSA TERRA 34 PN Noise protection boards in a conventional drywall partition on a wooden or metal frame can reduce the level of penetrating noise by two to three times.

Apply this material and for overlapping on logs or beams - at the same time, a reliable barrier to noise is created, and effective thermal insulation.

Insulating materials of the "URSA PUREONE"

series The appearance of URSA PUREONE series heaters seems to mark literally a revolution in the production of mineral fibrous thermoinsulating materials. Even an inexperienced glance immediately shows how different they are from their "brethren".It is a snow-white mineral wool with absolutely special qualities.

For the production of such materials, natural components are used - quartz sand of the highest degree of purification. But the main "highlight" of this technology is a complete rejection of binders based on formaldehyde resins and phenols, the use of recycled products is completely ruled out.

As a binding fiber in a single mass of the component, acrylic is used, which although it is an organic compound, but is known for its absolute neutrality, safety for human and animal health, harmless to the environment.

By the way, the unique pure white color of the materials "URSA PUREONE" is not the result of any coloration, since the natural shade of the quartz melt is just such - bright white. And the acrylic component just keeps this natural color.

The environmental safety of heaters on acrylic binders has been extensively tested in accordance with the most stringent international standards. According to the unanimous conclusion of the specialists, the thermal insulation "URSA PUREONE" meets the highest requirements of cleanliness and safety, and therefore is allowed to be used in children's educational and medical institutions. Naturally, it will suit perfectly for the conditions of a residential house or apartment.

Acrylic processing of quartz fibers gives them special elasticity. They become much less brittle, that is, the insulation does not "dust", it is convenient to work with it, since even to the touch it resembles a natural cotton fiber and is not capable of causing skin irritation.

The increased elasticity of fibers is also a big plus to the soundproofing capabilities of the material. In such an elastic environment, sound waves quickly lose their energy, dissipate, become unable to "swing" the partitions for further sound propagation.

The assortment of "URSA PUREONE" is represented by three types of material:

• "URSA PUREONE 34 PN"

This universal insulation is made in the form of slabs, convenient for mounting on any building structures. It has excellent thermal insulation properties and the highest noise attenuation - it belongs to the class "A".

Application areas of this material are practically unlimited, that is from the roof top to the thermal insulation of cold floors on the joists or beams from below, including, of course, the insulation of the facade walls from the outside or from the inside, creating acoustic ceilings and partitions.

• «URSA PUREONE 35 QN»

Specifications and applications of this type of insulation are similar to the previous one. The main difference is in the applied technology of "elastic felt" about which it was already mentioned above. Such boards are more convenient in installation between the guides of the frame structures and between the rafter legs of the roofing system.

There is a difference and in the form of release - it is easy to transport and install "slabs in a roll".

• «URSA PUREONE 37 RN»

Same universal and highly efficient material, but available in the form of long mats.

This type of release is especially in demand for fast installation in large areas or for insulation and noise insulation of curvilinear building structures.

The main technical and operational parameters of the URSA PUREONE line heaters are listed in the table below:

Heaters of the URSA XPS line based on extruded polystyrene foam

In the range of thermal insulation materials of the trade mark " URSA" also provide heaters designed for the most extreme operating conditions - with increased mechanical stress, high humidity or even direct water exposure.

We are talking about insulation based on extruded polystyrene foam - this material is characterized by high resistance to heat transfer and, at the same time, pronounced mechanical strength.

In the production process carbon dioxide is used as a blowing agent - it is completely harmless to the environment. The addition of special flame retardants to the component composition sharply increases the fireproof characteristics of the material, although, of course, it is completely impossible to classify it as non-combustible.

Extruded polystyrene foam has practically zero water absorption, resistance to freezing and thawing cycles, so it is perfect for thermal insulation of the underground part of the basement and walls of the basement. It is used to create insulated blinds around the base of the building, since without special problems it transfers direct contact with water or vegetation. The only thing he really "fears" is ultraviolet radiation. But with proper installation and protection from direct sunlight, the longevity of the material is estimated at 50 years or more.

URSA XPS plates have adjusted dimensional parameters, they are equipped with special lamellas for joining adjacent elements, which greatly simplifies and speeds up installation.

• "URSA XPS N-III"

This is a universal hard foam polystyrene plate, which is widely used in all areas of construction.

Used for insulation of flat roofs of any complexity. In the case of pitched roofs, it is possible to arrange a solid layer of slabs over the rafter structure.

In wall constructions can be used as a warming layer for "wells".Excellent for creating a thermally insulated plaster facade.

Widely used for insulation of floors on any substrate, including - with subsequent pouring of screed or as a basis for further installation of the system of "warm floors".

Used for insulation of plinths, finely buried foundations, external and internal walls of basements.

Excellent for warming balconies or loggias in urban apartments.

The surface of the plates is given a special texture unevenness, relief, which facilitates the execution of plaster works on them.

• "URSA XPS N-III-G4"

Similar to the "URSA XPS N-III" for the technical characteristics of the slab, but presented in a wider range of thicknesses. The price for them is somewhat less, since by reducing the content of flame retardant additives, the combustibility class is also lowered to G4.In this regard, the recommended use - basements, foundations, plastered facades, floors with subsequent pouring screed.

• "URSA XPS N-V"

This type of slabs belongs to the category of the most durable, capable of withstanding extremely high loads, which, in principle, predetermines a specific scope from the application.

They are used for insulation of deep-lying foundations, floors in rooms where high loads are expected( for example, production halls), flat roofs, roads and railways, aerodrome runways. In private construction, the use of such insulation seems to be clearly redundant.

Branded membranes of the "URSA SECO" line

The creation of insulation constructions on walls and roofs often involves the mandatory use of special film coatings, with different "mechanism" of action, depending on the location. The "URSA" also provides this aspect:

• " URSA SECO A" is a vapor permeable diffuse membrane that is used to protect the mineral wool from wind and direct moisture penetration, but does not prevent the free release of water vaporin atmosphere.
• "URSA SECO AM" is a membrane similar in design, but thanks to a special three-layer structure with higher strength characteristics, steam diffusion and water resistance. Perhaps even use as a temporary roofing cloth for up to 2 months.
• « URSA SECO B» is a vapor barrier film that protects the insulation layer from direct moisture and water vapor. It is placed over the insulating layer inside the premises.
• « URSA SECO D» is a hydro and vapor barrier film of increased strength, the main application of which is the installation of reliable under roofing waterproofing. It has good resistance to ultraviolet, and therefore can be used as a temporary roof for 2 months. The material is capable of withstanding very significant loads during the installation of the roofing system and during its operation.

The main parameters of URSA SECO are given in the table:

	SECO A	SECO AM	SECO IN	SECO D
Surface density, g / m²	100 ± 10%	100 ± 5%	65 ± 5%	90 ± 5%

So, the main assortment of heaters and related materials of the brand "URSA", appliedin private construction. Tables and description will help you choose the best option, and it remains only to determine the thickness of the insulation layer. In this matter, the reader will also be provided with the necessary assistance.

How to determine the required thickness of insulation?

There is a fairly simple calculation algorithm. Its essence is set out in a special publication of our portal dedicated to the main heaters for external walls of .There is also a convenient calculator, which will simplify the independent calculations.
