Sandwich panels PUR Classic (PUR "Classic") based on the PU foam system of the international manufacturer Dow Chemical - three-layer panels with thermal insulation from rigid polyurethane foam with a density of 42-45 kg / m3.

Allow to reduce costs for cooling or heating due to thermal conductivity of 0.022 W / m * K.

According to PPU Europe, 115 mm thick PU foam saves 162 kWh per sq. m of insulated surface.

The unique, deepest 20 mm docking profile on the market ensures that there are no cold bridges.

Service life of panels: from 50 years.

Sandwich panels PUR Classic (PUR "Classic") on the PU foam system of the international manufacturer Dow Chemical provide thermal insulation of the room and do not absorb water.

PUR Classic panels with polyurethane foam are intended for:

• for the construction of refrigerating chambers , freezing industrial warehouses;
• insulation of existing buildings in the food, agro-industrial, pharmaceutical industries;
• for low-rise frame construction of houses and cottages.

  The products are certified and undergo strict quality control (TU 5284-003-7798354).

ProfHolod produces PUR Classic

• for walls,
• for ventilation shafts, air ducts, ventilation ducts, etc.

Recommendations for choosing the thickness of a sandwich panel 

Design

Structurally, the sandwich panel is a three-layer structure:

- external sides: coating of high-grade metal of Russian production (Novolipetsk Metallurgical Plant, Severstal, INSAYUR Group of Companies), thickness 0.5-0.7 mm;

- filler: rigid fine-mesh polyurethane foam, foam density in sandwich panels 40-42 kg / m ³ ; thermal conductivity coefficient of polyurethane foam insulation k = 0.022 W / mK

Metallic coating options for wall panels:

• Cold rolled galvanized steel;
• Cold rolled galvanized steel, painted with polyester paint in color as per RAL catalog;
• Pural coated cold rolled galvanized steel;
• Cold rolled galvanized steel with plastisol coating;
• Cold rolled galvanized steel coated with polyvinylidene fluoride (PVDF).

It is possible to manufacture panels using non-standard coatings:

• Kraft paper;
• Foil on paper base;
• OSB;
• Chipboard;
• Plywood;
• Alumozinc;
• Glass magnesite;
• Plastic;
• Laminated material, etc.

The newest Italian-made equipment (periodic line of SAIP company, continuous line of PuMa company) for the production of PPU wall sandwich panels, the use of high-quality materials and components, high professionalism of specialists guarantee the durability and reliability of ProfHolod products.

Locks

Sandwich panels PUR Classic ("PUR Classic") "ProfHolod" are manufactured with the deepest joint profile "thorn-groove" 20 mm on the market, which provides:

1. Maximum thermal and waterproofing of joints
2. Elimination of cold bridges
3. Minimum consumption of polyurethane foam when joining

Depending on the thickness of the wall panels, ProfHolod will produce a single, double or triple thorn-groove.
