Roofing PPS panel sandwich

Panel sandwich wall — the easy three-layer panels consisting from two external the zinced and painted sheets (covered with a protective film) and a heater layer from expanded polystyrene with a density of 15-25 kg/m3.

• Covering: The galvanized painted sheet metal 0,4-0,6 mm thick

• Filler: expanded polystyrene

• Sheeting: Polyethylene film 50 microns thick

• Panel thickness: 50-300 mm

• Working width of the panel: 950 mm / 1150 mm

• Panel length: to 16000 mm

• In addition: Various colors of external and internal surfaces of panels

It is known that today the most power effective heater applied in the construction and refrigerating markets is expanded polystyrene. Coefficient of heat conductivity of this material of 0,022 W / m*k.

The PANEL CONSTRUCTIONS company offers wall and roofing a panel sandwich with thermal insulation from PPS from which in short terms you will be able to construct or warm:

• shop, supermarket, mall;
• production, office building;
• logistic complex, refrigerating warehouse;
• climatic chamber;
• storage for vegetables, fruit;
• hen house, objects of agricultural purpose;
• service station, gas station, car wash;
• change house, protection post;
• the refrigerator, shop on wheels;
• the fast-built energy saving house, giving, garage, any other utility room.

Polyurethane call the chemical polymeric compounds which are formed in result of reaction between liquid isocyanates and polyols. At a certain ratio of an isocyanate and polyol the rigid penopolisterola having porous structure with the closed cells filled with gas with extremely low heat conductivity turn out. Besides excellent heat-insulating qualities rigid penopolisterola have sufficient hardness and can maintain considerable loadings.

Technological process of production a sandwich of panels with thermal insulation from expanded polystyrene is divided into two stages. At the first stage the profile of sheet material with "thorn groove" locks is formed, at the second stage already under a press to be made filling of intersheet space a PPS panel sandwich by expanded polystyrene which forms a heater layer. As thermal insulation only qualitative two-component polyurethane of production Dow Chemical is used.

Unique characteristics of PPS:

• low heat conductivity of expanded polystyrene (0,022 W / M*K) remains more than 50 years;
• low weight of PPS (40-42 kg/m3);
• high adhesive durability;
• environmental friendliness. On hygienic norms application in refrigerating equipment for food products is authorized;
• parovodonepronitsayemost;
• it is not subject to decomposition and rotting;
• does not collapse as a result of seasonal temperature fluctuations, an atmospheric precipitation;
• it is steady to aggressive (acid and alkaline) to Wednesdays;
• it is steady against influence of rodents and insects;
• it is steady against influence of a fungus and mold;
• good acoustic isolation.

Comparison of PPS with other heat-insulating materials

*** At a thickness of metal facings a sandwich of panels of 0.45 mm, PPS density - 42 kg/m3, density of mineral wool - 115 kg/m3, expanded polystyrene density - 50 kg/m3

As facing materials a sandwich of the PPS panels can be applied:

• rolled galvanized steel 0,45-0,6 mm thick;
• rolled galvanized steel with a polymeric covering polyester 0,45-0,6 mm thick;
• rolled stainless steel of the AISI304 brand (for foodstuff) or AISI430 (for nonfood products) 0,5-0,6 mm thick;
• paper with a density of 150-200 g/m2;
• folgirovanny paper;
• moisture resistant plywood or oriyentirovanno-struzhechny plate (OSB);
