Lightweight Sandwich Panel Eps Fiber Cement Wall Board
Introduction of sandwich panels
Light weight insulation wallboard batten use fiber cement board or calcium silicate board production equipment and technology and inorganic insulation board production equipment,finish only one process,it is divided double layer panel and core material and no core material of the double panel battens,the core material is mainly composed of silicate cement and EPS foam and adhensive,fiber combinations.Its mainly used as interior wall partition and exterior wall substrate,instead of clay brick and color steel plate and other building materials,its a energy -saving innovations material, and its doesn’t need to re-surface material processing,you can use just surface treatment and decorative finishes paint.Sheet completely prefabricated in the factory according to GB8624-2006<building material and products combustion performance grading >standards,the combustion performance is class A1, thermal resistance to meet the building’s exterior wall system requirements. The product is no toxic, tasteless, non-polluting, moisture proof, fireproof,mildew-proof, mothproof, light weight, sound insulation, environmental protection, energy saving and insulation,construction easily and etc features of the new multi-purpose building materials.

Application:
The sandwich panels can be used in large industrial plants,warehouses
supermarkets, hospitals, stadiums, cold storage, activities room, buildings plus
layer, clean workshop and heat insulation fire place.
The temporary facilities in the construction site, such as office, warehouse.
It is also widely used for cleaning workshops, industrial factory buildings, office
buildings, stadiums, villas, and public buildings, etc.
Advantages:
1) Being light in weight handling & installation become very easy.No brick and plasterign are required
2) 5% Additional floor are will be available on replacing 125mm birck wall with 50mm,75mm panels
3) Specially designed tongue and groove(patent) arrangement ensures a perfect joint and makes constrution faster
4) More suitable for seismic & cyclone prone zones
5) Excellent adhesion between core & facing sheets
6) Good Sound & thermal insulation properties
7) Humidity,water and termite resistant properties to withstand any adverse weather conditions
8) Panels have a fire rating of 4h.
