More than 20 years on the market
The company's success began in 2002, when two artists — Andrey Ragozin and Evgeny Tsapko — created a small creative workshop for producing wooden carved items. The masters' work was quickly noticed, and within a year they were invited to participate in the reconstruction of the Konstantinovskiy Palace in Strelna.
After the success of this project, the company focused on recreating palace interiors, furniture, church furnishings, and carved decorations in various artistic styles. They worked with cultural heritage sites: The Hermitage, the Alexandrovsky Palace, the Troitsko-Izmaylovsky Cathedral, the Sheremetyevsky Mansion, and many others.
The masters' task — and still is — to create wooden items with the highest level of detail and understanding of every element, based on impeccable knowledge of artistic laws and interior styles.

South Korean luxury brand HI WOOD: absolute leadership in molding production
The South Korean company HI WOOD is an undisputed global leader in the production of decorative molding from ultra-high density polystyrene of the premium and luxury segments, with an impeccable international reputation built over more than 35 years of presence in the global market. The company's production facilities covering more than 38,000 square meters are equipped with European high-class equipment for extrusion of polymer profiles of maximum dimensions from leading German, Swiss, Austrian, and Italian manufacturers with computer control systems based on artificial intelligence.
The material of crown molding A178 is produced using a unique patented continuous extrusion technology of high-grade polystyrene raw material with the use of special modifiers and nanoreinforcers developed by the company, increasing density to record 43-50 kg/m³. Closed-pore nanotechnological structure with pore size 0.04-0.08 millimeters ensures ideal balance between relative lightness and maximum mechanical strength of the grandiose dimensions 110x140 millimeters. Molten polymer mass at 195-208 degrees Celsius is extruded through a specially designed ultra-wide die made of hardened tool steel with geometric accuracy to 0.01 millimeter.
Quality control of HI WOOD products is performed at all stages of the production cycle. Finished crown moldings of maximum size are controlled by 48 parameters including geometric dimensions with tolerance not exceeding 0.1 millimeter on the massive profile of 110 millimeters height and 140 millimeters width, ideal surface quality without any defects, absolute straightness over the entire 2000 millimeter length.
Excellent technical characteristics of the maximum palace profile
The moisture resistance of maximum density polystyrene makesDecorative cornices made of polystyreneA178 absolutely universal solution for any rooms. Water absorption coefficient does not exceed 1.1 percent after 24 hours of full immersion in water at 23 degrees Celsius, which absolutely completely excludes any deformation even under extreme humidity conditions of luxury spa centers, hammams, Olympic pools, premium-class saunas, international aquaparks. The product maintains absolute ideal geometric dimension stability at relative air humidity ranging from 0 to 100 percent.
The temperature stability of ultra-high density polystyrene ensures flawless operation in an extremely wide range from minus 65 to plus 98 degrees Celsius without any change in the material's physical-mechanical properties or geometry of the grandiose 110x140 millimeter profile. The crown molding does not crack under extreme Arctic cold and does not deform under excessive heat in overheated rooms. 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 millimeter for a 20-degree temperature variation.
The mechanical strength of ultra-high density polystyrene is achieved through an optimized molecular structure with maximum concentration of polymer chains and special reinforcing nanoreinforcers. The bending strength reaches record 3.1-3.6 MPa, ensuring exceptional reliability of the grandiose massive product of 110 millimeters height and record width of 140 millimeters during long-distance transportation, storage, and installation at great heights.
The ecological safety of polystyrene is confirmed by international quality certificates ISO 9001:2015, ISO 14001:2015, ISO 45001:2018 and sanitary-hygienic certificates. The material does not contain toxic components, formaldehyde, phenols, heavy metals. The hypoallergenic nature of the material allows using the crown moldings in any rooms without restrictions.

The installation zone is cleaned with professional means. Loose areas are removed down to a solid base. Depressions deeper than 10 millimeters are filled with fiber-reinforced putty.
The prepared base is treated with professional deep-penetration primer in two to three layers with intermediate drying for maximum strengthening under the record-wide crown molding of 140 millimeters. Marking is performed using a professional rotary laser level. From the ceiling, a distance of 110 millimeters minus a gap of 10-15 millimeters is measured.
Reinforced professional-grade mounting adhesive is applied as a continuous wide strip of 15-18 millimeters across the entire width of 140 millimeters. Due to the maximum weight and width, a maximum amount of adhesive is required for secure fixation.
Additional mechanical fixation with professional anchor screws of length 80-100 millimeters is mandatory for the most massive crown molding. Screws are screwed in at intervals of 250-300 millimeters across the entire width of 140 millimeters into the structural base.
The cost of the A178 cornice is 4600 rubles per 2-meter section, which is 9-14 times lower than wooden counterparts of grandiose dimensions 110x140 mm and 5-7 times lower than polyurethane cornices from European manufacturers of maximum sizes.
