Sandwich Panel - Essential Solution For Energy Saving
A sandwich panel is a type of roofing system that consists of two metal sheets with an insulating core in between. Sandwich panel roofs are widely used in industrial, commercial and residential buildings because they offer many advantages over traditional roofing materials.
Sandwich Panel
Sandwich panel is widely used in Prefabricated House walls and roofs. Although EPS is one of the best material that has a very high efficiency in heat insulation, there is a trade off with fire protection. EPS stands for expanded polystyrene, which is a lightweight and rigid plastic material that has good thermal insulation
- Easy To Install
- Excellent Thermal Insulation
- High Structural Strength and Durability
- Smooth And Clean Surface
Sandwich Panel has a wide range of applications, such as roofs, walls, floors, partitions, cold storages, container houses, etc.
Sandwich panel EPS can be classified into different types according to the thickness of the core and the surface material. For example:
– Sandwich panel EPS 50mm: This type has a core thickness of 50mm and a steel sheet surface. It is suitable for external walls, interior walls, floors, etc.
FAQ
Solar Panels on Sandwich Panel Roof Tops
Solar Panels can be installed on sandwich panel roof tops. Since they are lightweight and strong, this makes them ideal to use it together with solar panels.
- Use a mounting system designed for sandwich panels
- Make sure the sandwich panels are strong enough to bear that additional solar panel loads
- Seal any penetrations on the roof so that there is no leakage.
What Are Other Infill Materials?
There are some variety of infill materials, like Polyurethane (PUR), Polyisocyanurate (PIR), Rockwool. The last one is inorganic material that makes it fireproof.
Can We Use Aluminium for the skin of panels?
Aluminium also widely used for sandwich panels to make more corrosion resistant. Strength of aluminum is lower comparing the steel counterparts so thicker sheets should be used.
Which thicknesses should I choose?
For external walls and roofs, 50mm infill thickness is selected, but if there is a need for better heat insulation as in the cold rooms, then 100mm thick is chosen.
