WALL SANDWICH PANEL
Secret Screwed wall sandwich panels are great construction materials for all types of buildings, including leisure, hospitals, industrial, retail, commercial, equipment storage, garages, boxes, cold and freeze stores houses and for thermal insulating packing for existing buildings.
ADVANTAGES OF PU SANDWICH PANELS:
Strong heat isolation- High level of fire resistance
- High density
- Weather resistance
- Design flexibility/simplicity
- Easy superficial cleaning
- Construction lightness (building opportunity without the foundation in several cases)
- Materials multiple usage ability
- Stands out for economy of construction (does not need additional repair working)

SANDWICH PANEL CATALOGUE
CONSISTENCE
Sandwich panel metal surface consists of galvanized iron sheet and organic covering.
Organic covering is characterized with corrosion stability that contributes long service life of the material.
According to the corrosion type upper site metal cover of sandwich panel consists of: organic layer 25µm and galvanized layer 20 µm that can be raised up to 200 µm upon requirements
PREPAINTED GALVANIZED SHEET IRON
Panex uses prepainted galvanized sheet iron in coils that is produced according to ECCA
(The European Coil Coating Association) standards.

POLYURETHANE SOLID FOAM
In sandwich panels we use polyurethane foam with the best heat isolation performance. Polyurethane foam is waterproof material and has antibacterial characteristics.

HEAT ISOLATION
To achieve the desired results in case of low thermal insulation materials it is necessary to
increase material thickness. While in case of polyurethane foam the minimum thickness of
material is remained.
According to thermal insulation values, multifunctional usage and exploitation durability, today polyurethane foam is the optimal solution.

MECHANICAL STABILITY
Lifting capacity is an important issue while sandwich panel selection for the specific building. Factors such as own weight, wind load, snow load and temperature can effect on building as together as separately.
Sandwich panel consistent metal sheets and fillers between these two sheets have low lifting capacity but composition which is made by these materials is a new system and its lifting capacity is compatibly improved.

FIRE RESISTANCE RATING
PUR material is effective while fire. Polyurethane foam with its chemical coponents can reduce and prevent fire from spreading that increase product efficiency.
Panex polyurethane panels are classified with B2 fire resistance rate (based on TS EN 14509 standarts)
