Why you should prefer mixed construction over prefabricated houses.
(mixed vs. prep)
Factory production is the only common point between composite and prefabricated. Beyond that, the differences in relation to the similarities of the two (2) constructions are huge. Architectural flexibility as well as the construction of high-rise buildings is the fundamental difference between them. Below you will read in more detail the differences between the two (2) constructions.
The way the composite structure is constructed from a metal frame is far superior to the prefabricated structures. It allows the housing of buildings with large openings (ie without intermediate columns) with the construction of relatively low beams, which is often impossible in prefabricated structures. So everyone can design what they want without the limitations they encounter in a prefabricated house due to the predetermined dimensions in their construction molds.
Because they are light constructions, their use is indicated in additions to existing buildings, something that is impossible in the prefabricated buildings (Prefabricated houses). Most of the time, reinforcement of the existing building is not required due to the low weight of the metal frame and the construction materials (YTONG masonry, dry construction, etc.)
Flexibility in architecture compared to prefabricated houses that do not have… Architectural flexibility and improved aesthetics: The much thinner grid of placement of the columns ensures much more flexibility in the design of the building, ie much greater ease in shaping the floor plan
Superiority in the degree of seismicity over common constructions because concrete as an inelastic material does not have the ability to deform to the forces of the earthquake and return to its original state. When a crack occurs, in an impending earthquake due to the memory of the concrete the forces affect the building cumulatively resulting in extensive damage.
- In composite construction, in addition to the freedom of architectural design versus prefabrication (Prefabricated constructions), we have the possibility of constructing multi-storey buildings. A prefabricated building may not exceed three (3) floors in height in relation to the metal structures used against crowns for the construction of multi-storey buildings and skyscrapers.
- In a composite construction, even in the event of damage after an earthquake, the replacement of a member (Metal column-Metal beam, etc.) is a process of a few days, as opposed to prefabricated structures where damage repair is often impossible.
- Because they are light constructions, it is advisable to use them in additions to existing buildings, something that is impossible in prefabricated buildings (Prefabricated houses). In most cases, reinforcement of the existing building is not required due to the low weight of the metal frame and the construction materials (YTONG masonry, dry construction, etc.)
- Smart Building after years of experience and research in the field of construction and in collaboration with the National Technical University of Athens (NTUA) has established in its construction the external thermal insulation. External thermal insulation achieves excellent energy indicators based on the restrictions established by KENAK in recent years on building permits. The Thermo Facade embraces the building externally so that changes in the outside temperature find an obstacle and do not pass to the building materials, which have no thermal insulation properties by themselves, something that happens in the prefabricated buildings (Prefabricated houses) where the insulation is in the middle of masonry.
