Introduction of sandwich panels
1. Introduction
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.
2. Size:
Length: 1500-3000mm(usually 2270mm)
Width: 610mm
Thickness: 60/75/90/100/120/150/180mm
3. Advantage:
Sound-insulation
Best hanging force
Area –saving,fire-proof
Waterproof and damp proof
Anti-seismic and impact resistance
Largest Span and height thin webbed wall
Energy-saving, light weight, environment-friendly
Most civilized, healthy and high efficient construction
4. Application:
For interior and exterior wall partition on steel or concrete
structure building, new construction or renovations. It can replace
construction materials such as block, wire spatial grid structure
perlite board, perlite porous board and etc. It can widely be
applied to wall materials of various high and low buildings such as
bank, office building, hospital, school, hotel, mall, amusement,
old house reconstruction, residence and workshop.
