Advanced technology of compact profile production

The material of the A53 cornice is produced using continuous extrusion technology of premium-grade polystyrene raw material with the use of special modifiers that increase density to 36-40 kg/m³. Closed-pore structure with pore size of 0.1-0.2 millimeters ensures optimal balance between lightness and mechanical strength of the product. Molten polymer mass is extruded through a precision forming die with geometric accuracy up to 0.05 millimeters, creating a profile with perfectly repeating configuration along the entire length of the plank.

Moisture resistance of polystyrene makesDecorative cornices made of polystyreneA53 is a universal solution for any room. Water absorption coefficient does not exceed 1.8 percent after 24 hours of full immersion in water, which eliminates deformation, swelling, or loss of decorative qualities. The product maintains stable geometric dimensions at relative air humidity ranging from 20 to 95 percent, allowing use of the cornice in bathrooms, kitchens, glazed balconies, laundries, saunas without any restrictions.

Polystyrene's temperature stability ensures flawless operation in a range from minus 35 to plus 75 degrees Celsius without changes in physical-mechanical properties. The material does not crack during freezing, typical for unheated country houses in winter, and does not deform during heat in overheated attics in summer. The linear thermal expansion coefficient is 0.07 mm/m per degree, which at a plank length of 2000 millimeters results in a size change of only 0.14 millimeters over a 20-degree temperature difference, practically eliminating thermal deformations.

Mechanical strength of high-density polystyrene is achieved through an optimized molecular structure with increased concentration of polymer chains. The bending strength limit is 2.4-2.8 MPa, ensuring reliability of the compact product during transportation and installation.installation of decorative cornices made of polystyreneA53 does not require special care — despite its small dimensions, the profile withstands moderate mechanical loads without forming dents or chips.

Acoustic properties of porous polystyrene provide partial reduction of airborne noise penetration through construction joints. The porous structure of the material partially absorbs sound waves in the high-frequency range typical for household noise, voices, and household appliance operation. The cornice around the room creates an additional acoustic barrier for sound transmission through technological gaps between the wall and ceiling.

Professional technology of rapid installation

Surface preparation before installing the compact cornice A53 requires minimal effort due to the profile's ability to compensate for minor irregularities. The installation zone is cleaned of dust, cobwebs, and oily contaminants using a dry brush or damp sponge. Loose plaster areas are mechanically removed, and dents are filled with gypsum putty. The surface is treated with a deep-penetration primer to strengthen the surface layer and improve adhesive bonding.

Installation line marking is performed using a laser level or plumb line to ensure strictly horizontal positioning of the profile. From the ceiling, the distance equal to the cornice height minus 5-7 millimeters of compensatory gap is measured. Control points are marked every 600-700 millimeters and connected by a continuous line. Horizontal alignment is checked using a bubble level at least 1200 millimeters long.

Angular joints are cut using a miter box with 45-degree slots or a circular saw with a fine-toothed blade. For internal angles, the plank ends are cut from opposite sides to ensure tight fitting. The cuts are sanded with fine sandpaper P120 to remove burrs. If the room geometry is not ideal, the cut angle is adjusted using trial fitting methods.

Polystyrene adhesive of the 'liquid nails' type is applied to the back of the cornice in dashed lines with intervals of 150-200 millimeters. Due to the lightweight profile, the amount of adhesive may be less than for bulky items. After a 1-2 minute wait, the plank is pressed against the wall with even pressure.Barnaul polystyrene cornice purchaseA53 are secured with painter's tape for 3-4 hours until the adhesive begins to set.

Straight cornice sections are joined with a minimal gap of 0.5 millimeter. The ends of the joining planks are cut strictly perpendicular to the profile axis. A thin layer of adhesive is applied to the ends, and the planks are pressed tightly together. The formed joint is filled with white acrylic sealant, excess is wiped off with a damp sponge. After polymerization, the joint is sanded with fine sandpaper.

Final finishing includes filling gaps between the profile and surfaces. Gaps up to 2-3 millimeters are filled with acrylic sealant, smoothed with a moist putty knife.
