Rapid construction using convenient sandwich panels has become quite popular in Ukraine in recent years. With their help erect office buildings, car washes, warehouses, hangars. The material consists of two metal sheets with an inner layer of thermal insulation. With the help of grooves, they are easily mounted in a variety of designs.
For the construction of low-rise residential buildings, panels are often used, the outer layers of which are made of pressed wood and resin, and the layer is made of expanded polystyrene. Such material for construction allows you to build housing with excellent thermal insulation properties, besides, it is highly environmentally friendly. The terms of construction with the use of sandwich panel technology are very short - from a couple of weeks to several months.
The advantages of this type of construction of objects are obvious:
-
Very low cost of housing: for 2-storey houses it can vary from 500 to 4000 UAH. per sq.m.
-
Projects of houses and other structures can be created individually at the request of the customer, as the material allows you to build objects of any complexity and design solutions.
-
Excellent heat-saving characteristics of buildings, as well as savings on foundation pouring due to the lightness of such a structure, have recently attracted more and more customers.
-
The ease of work on interior and exterior decoration is due to the smoothness of the panels, their combination with any kind of finishing materials, significant savings on putties and primers. For example, the creation of a garage from sandwich panels will take about 10 days, while its cost will compare favorably with the same building made of brick or concrete.
Disadvantages:
- According to some experts, the high fire hazard of expanded polystyrene can be attributed to the disadvantages of sandwich construction.
- There is also evidence of an increase in humidity in houses made of such material, which contributes to the growth of mold fungi on the walls.
- Another disadvantage is the gradual decrease in the thermal insulation properties of expanded polystyrene.
The recommendations of professionals are as follows: for the construction of residential premises, it is advisable to purchase sandwich panels with a layer of mineral insulators that have no claims to protective properties.
