Technical characteristics and types of insulation Ursa

Minvata Ursa is used for insulation of walls, roofs, communications. Insulation keeps you warm and reduces incoming noise. The material is of high quality and has a long service life. The company has been producing Ursa insulation since 2002 and has developed a number of innovative technologies for the production of products.

Features of Ursa material

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 high temperature. 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

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, 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

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 relate only to the atmosphere, since the surface of the insulation can withstand other temperature loads, the limit of which is + 100˚С, and some categories retain properties at + 180˚С. 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.

Line of materials based on mineral components

Mineral wool is characterized by fibrousness depending on the initial component underlying. The structure is spatial, corrugated, the layers are divided horizontally or vertically.

The manufacturer designates products depending on the raw material composition:

• Fiberglass products are marked with the Geo prefix. The products are classified as safe for humans and environmentally friendly materials.
• A product with the PureOne index is created on the basis of glass threads. The composition contains acrylic components. This type of insulation is installed to protect against the cold in childcare facilities and hospitals.
• The non-combustible material Terra is ideal for insulating wooden buildings. The composition includes natural ingredients, the insulation does not harm the environment and humans.
• Thermal insulation based on extruded polystyrene foam is marked with the XPS attachment and is a durable and reliable insulating version of the insulation.

Ursa thermal insulation is manufactured in accordance with technological standards that regulate the content of the binder.

Ursa GEO

The heat insulator is allowed for use in rooms with a high risk of ignition, since the material does not emit harmful components when heated.

Ursa Geo products are available in the following range:

• Light;
• Pitched roof;
• Frame P;
• Mini;
• Facade;
• Noise protection%
• Universal plates.

Mats with one foil side are designated M-11F and M-11, double-sided - M-25F, M-25, M-15. Plates are marked P-60, P-15, P-45, P-20, P-30.

With a low specific gravity, Geo products provide high-quality protection against cold and noise, thanks to the original fibrous structure. The material does not decompose, does not burn, rodents and insects do not settle in the thickness.

Ursa PureOne

The characteristics of Ursa insulation show that the material is 95% natural substances, which have passed quality control during the production process. The material is produced in accordance with sanitary international standards and is included in the class of environmentally friendly insulators.

Line names:

• 35QN rolls with dimensions 1200 mm x 3900 mm;
• plates 34PN with dimensions of 1250 mm x 600 mm);
• rolls 37RN 1200 mm x 100 mm).

The products are flexible when installed in curved structures due to the thinner fibrous elements in the structure. The material does not emit dust and odor during installation. The white color is obtained through the use of quartz sand.

Ursa TERRA

The products were developed for private buildings, but also meet the requirements of professional construction. Plates of this type are distinguished by their small size and rigidity with sufficient elasticity and flexibility.

An assortment of Terra brand insulation is produced:

• plates 34 PN;
• mats for insulation of highways and ventilation ducts 34 RN.

The sheets are characterized by a good thermal and sound conductivity index and show moisture resistant qualities. The production technology provides for the use of water-repellent additives.

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 weight (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

In the EPS product category, only one type of product is produced. The material has a universal application, but it is more often used for insulation work during the construction of railroad embankments, runways, lower and underground floors of buildings.

URSA XPS range:

• high strength material N-V, sold in slabs 60 x 125 cm;
• N-III sheets are produced with straight and stepped side edges;
• N-III-G4 slabs are produced with a thickness of 3-10 cm, size 60 x 125 cm.

Products do not react to the action of acids, fats, alkalis, lime, bitumen and other corrosive substances, but decompose when in contact with tar, hydrocarbons, gasoline and formic acid.

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.

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;
• vapor permeability and biostability;
• 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

Universal thermal insulation Ursa is used in any construction process. The versatile characteristics allow the protection to be used for difficult curved surfaces.

Areas of use:

• pitched and flat roofs;
• foundations in damp places;
• walls outside, inside and as an intermediate layer;
• partitions;
• heating mains;
• highways and railroad elevations;
• airfield strips;
• outbuildings, balconies;
• saunas and baths.

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.

Installation of thermal insulation Ursa

Mineral wool is attached to the walls and pressed with 50x50 cm bars so that there is an air space between it and the finishing layer. Wooden elements are mounted at a distance of the width of the roll so that they hold the edges of the canvas. Expanded polystyrene plates are glued to the surface of walls or floors using cement-adhesive mortars or polyurethane composition. Before gluing, walls, ceilings or floors are treated with primer for better adhesion. On them, a screed or starting putty is performed using a plaster mesh.

For reliable attachment to vertical surfaces, special dowels with a large head (up to 10 cm) are used. The ventilation gap between the insulation and the wall of the house ends at the bottom and top with vents - mounting holes for normal air flow. Rolls and slabs are tightly stacked side by side. If the material is put in 2 layers, the next layer overlaps the joints of the previous one for maximum efficiency.

If a frame is used, a finishing finish is attached to it in the form of sheets of chipboard, fiberboard, OSV, plastic panels or MDF. The Ursa insulator works well with all types of building finishes.
