HOW ABOUT OUR SANDWICH PANEL

The sandwich panels are connected to each other with a unique joint which giving stability and flexibility. Each panel is easily inter-changeable. The panels come with galvanized as well as aluminum sheets with an attractive baked enamel coating, PVC-foiled or uncoated.

The core material is Rockwool, EPS (Expanded Polystyrene) or XPS (Extruded plastic polystyrene) with a density determined by customer’s requirement.

The panels have excellent properties. The demand for fire protection, sound reduction and appearance are fulfilled by the combination of selected materials as PVC coated steel sheets and mineral wool.

The panels widely use as the structural and heat insulate material which related to platform lift, petroleum, architecture, chemical, packing, cold storage, military affairs, spaceflight, airflight, transportation, industry design.

ROCKWOOL WALL PANEL

ROCKWOOL WALL PANEL is a perfect solution for buildings that require high sound insulation, have a fire risk or those in which inflammable/explosive materials are stored.

With thicknesses between 15, 25, 30, 50, 80-150 mm, as well as external or secret fixing options, mineral wool sandwich wall panels produced in compliance with the international standards create a comfortable, reliable, and energy-efficient environment in your buildings. It offers aesthetical solutions for your buildings with lined and micro lined surface types and a wide range of colors.

Rook wool is non-combustible material, so the rockwool panel has good fire-resisting property .the test shows temperature of the panel fire-proof is as high as 1000C,the test results obtained by Istituto Giordano S.P.A is as follow:

Roof and Wall panel thickness 100 REI 120 Roof and Wall panel thickness 80 REI 60 Roof and Wall panel thickness 50 REI 30

The roof and wall panels,thickness 50-80-100mm,were classified 0/1 for reaction to fire.(Materials are assigned a class from 0 to 5,the higher the class, the higher degree of combustion.)

Effective Characteristic of Sound Resistant

Rock wool panel achieves a notable reduction in air borne sound transfer,particularly when specifying a perforated liner.The impact of rai and hail on the metal sheet , a problem on most standard constructions ,is greatly reduced when adopting HKF-RW panel in thicknesses of 50-100mm with 100kg/m3 rock wool fibre insulation has achieved results of RW=29-30 dB according to UNI 8270/7 and 717/82.

EPS (EXPAND POLYSTYRENE) WALL PANEL

EPS “expanded polystyrene" foam, is an economic and lightweight thermal insulation material derived from petroleum in the form of foam, generally white thermoplastic consisting of 98% air and 2% plastic with closed porous structure.

Small polystyrene granules are heated with water vapor and expanded by inflating with pentane gas, an organic component. The pentane gas in numerous small closed pores, which form in the granules, is replaced by air during production and within a short time after production. After dried in special silos and inflated with water vapor again, the granules stick firmly to one another without any gaps and take the shape of the mold they are in, resembling honey combs; thus, EPS thermal insulation blocks are formed. This motionless and dry air, which is trapped in the granules with small closed pores, enables EPS thermal insulation to provide superior thermal insulation for buildings.

The polystyrene sandwich panel is EPS foam core material that inside between Upper and lower layer of metal sheets or decorative polywood sheets . Middle condensed polystyrene foam board.

With outstanding advantages, they widely being used in big projects like: industry factory, warehouse、public architecture, refrigerator, etc.

PU (POLYURETHANE) WALL PANEL

Polyurethane foam sandwich panel is fit for the projects which have serious require of keeping warm. Polyurethane core material is considered to the best material in keeping warm and thermal insulation.

The Polyurethane block material become steady after it froth, then combining with metal plates. The characteristics of this technique are: the polyurethane froth, after this chemical reaction is stable, we cut the polyurethane into pieces which with different thickness. The polyurethane sheet material has stable physical performance, it can combine with prepainted gaivanized steel sheets, the surface is smooth and the whole performance is excellent.

The characteristics of polyurethane foam sandwich panel:

Polyurethane foam sandwich panel(the abbreviation of Polyurethane is PU sandwich panel)have characteristics of high load intensity, small water-absorptivity , and the stability in either low temperature or the high temperature is good, the service life is long, thermal insulation performance is outstanding and so on.

Good supporting, heat resistant, sound-insulated, sound absorption, light quality, non-toxic, odorless, green environmental protection.

Polyurethane foam sandwich panel can cementation with the steel plates, the cements, the fiberboards, the bricks and many kinds of materials very strongly, in usual situation, it would not fall off and still strengthen its thermal insulation and waterproofing effects.
The unique produce foaming craft made the products have exquisite and even abscesses, the Thermal conductivity is low, the size stability is good, is very suitable for both of the low pressure and the high pressure construction.

Polyurethane foam plastics thermal stability is quite good, when the temperature is lower than 120 C, the volume and the intensity have no obvious change, its Thermal conductivity is small, when the density is 0.03kg/m3, the heat conductivity is only 63J(m.h.k)(15cal/m.h.k).

High in energy efficiency, offering comfortable and reliable environments, and in compliance with international standards, PU insulated Sandwich Wall Panels both cover your building and allow for an aesthetical appearance with external or secret fixing options, and with lined, micro lined and deep lined surface types.

PU insulated sandwich wall panels offer both aesthetic and smart solutions for your buildings thanks to its sandwich roof panels produced at desired heights ranging from 2-12 meters, in thicknesses ranging from 40-200 mm and in a wide range of colors.
