3A Composites Sandwich Panel System comes with concealed installation systems to meet the building’s aesthetics, wind load, water tightness, airtightness, insulation and fire safety requirements. This system is used as non-load bearing walls and partitions for facade and roofing applications.
Apart from providing a variety of sizes, thickness and colour options 3A Composites Sandwich Panel System can also meet various engineering needs and design requirements. This includes options for joint types such as concealed or exposed joints.
| Applications | Types of buildings |
|---|---|
| Exterior wall, interior partition, roofing and ceiling. | Data centers, manufacturing facilities, warehouses, cold storages, clean rooms and medical facilities. |
Wind load and permissible panel sizes
The diagram indicates the available range of panel sizes and permissible range lengths at a given panel width, depending on the wind load applied. The diagram applies to panels supported on four sides (corners fixed). Dimensional values for other systems are available on request.
| SYSTEM FEATURES |
|---|
ENERGY SAVING:
With excellent heat insulation performance, 3A Composites Sandwich Panel System can largely reduce heating/cooling expenses and keep the space inside the buildings at desired temperature throughout the year.
ENVIRONMENTAL PROTECTION:
The system uses natural and environmentally friendly materials that meet the environmental protection requirements in the countries of the European Union and the US.
SOUND INSULATION AND ABSORPTION:
Due to the use of high-density mineral wool, 3A Composites Sandwich Panel System has good sound absorption performance and also meets the requirements of various construction standards.
LARGE PANEL SIZE AND EVEN FLATNESS:
The system has a specially constructed composite structure produced on a continuous line that allows for a perfectly flat panel surface without the need for reinforcing ribs.
LIGHTWEIGHT:
3A Composites Sandwich Panel System has high strength and light weight – the weight of a 100 mm is about 22 kg/m2, which is much lower than a traditional concrete wall.
DURABILITY:
The system is designed to withstand harsh conditions and comes with a 10 year warranty.
QUICK INSTALLATION:
3A Composites Sandwich Panel System can be easily installed by fixing two long sides to meet horizontal or vertical layout requirements. It uses a specially designed dry fastening system which allows for a quick installation.
TECHNICAL SUPPORT:
3AC technical team provides assistance around product selection, fixing systems and installation methodology.
FIRE RATING/RETARDANCY:
3A Composites Sandwich Panel System has extremely high fire resistant mineral wool core.
