- Interior elements
- Exterior elements
Sandwich wall elements comprise a load bearing interior layer (thickness of the layer depends on the loads), exterior layer (usually 70–90 mm) and insulating material (glass or rock wool, polystyrene foam) installed between the two. Wiring ducts for electric, communications, etc. cables may be installed inside the wall elements.
Using sandwich elements has several advantages – among others, the speed of assembling the building, accuracy of dimensions of elements manufactured in the factory and wide selection of exterior finishes, sound-proofing and thermal insulation indicators complying with standards, fire integrity, ability to carry out construction work during the cold season.
Single-layer elements can be interior or exterior walls, load bearing or non loadbearing wall. Single-walls can also be acting as beam elements
