Specifications

Willing int'l has already exported different kinds of panel, such as polystyrene sandwich panel, rock wool sandwich panel. 

EPS Sandwich Panel Features

Polystyrene Sandwich Panel:

1) Structure: a) Upper and lower layer: uses many kinds of metal sheets or decorative polywood sheets

                   b) Middle: condensed polystyrene foam board

2)EPS Sandwich Panel Width: 1,000mm, 1,180mm

3)EPS Sandwich Panel Thickness: 40mm, 50mm, 60mm, 75mm, 80mm, 100mm, 125mm, 150mm, 175mm, 200mm, 225mm, 250mm

4) Length: depending on the design and conditions of transportation

5) Thermal conductivity: 0.032kcal/m.h.cFeatures

Rock Wool Sandwich Panel:

1) Rock wool is non-combustible material, so the rock wool panel has good fire resisting proper. The test shows the temperature of the panle fire-proof is as high as 10001°C

2) Roof and Wall panel thickness 100 REI 120

3) Roof and Wall panel thickness 80 REI 60

4) Roof and Wall panel thickness 50 REI 30

5) 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 the degree of combustion)

6) Rock wool panel achieves a notable reduction in air borne sound transfer, particularly when specifying a perforated liner.

The impact of rain and hail on the metal sheet, a problem on most standard constructions is greatly reduced when adopting CX-RW panels. The CX-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 ISO 717/82Payment terms: irrevocable L/C at sight, T/T (30% deposit, balance before delivery)
