The first layer is the inner part of the wall, which forms the interior of the home. Different materials are used depending on the project:<\/p>\n
* plasterboard;
\n* OSB or chipboard panels;
\n* cement-fiber boards.<\/p>\n
This layer provides a smooth base for finishing works such as painting, plastering or decorative coatings. It also improves the acoustic comfort in the rooms.<\/p>\n
2. Vapor barrier membrane<\/strong><\/p>\n After the inner lining, a vapor barrier membrane with an aluminum layer is placed, which plays a key role in the system.<\/p>\n Its main functions are:<\/p>\n * blocks moisture from indoor spaces; This layer creates a complete barrier to water vapor, which is critical to the durability of the structure.<\/p>\n 3. Metal supporting structure<\/strong><\/p>\n The main load-bearing element of the wall is the metal frame, built of:<\/p>\n * profiles 150\u00d755 mm; This system guarantees:<\/p>\n * high resistance to loads; Unlike wooden structures, metal does not deform, does not crack, and is not affected by weather conditions.<\/p>\n 4. Thermal insulation \u2013 stone wool 200 mm<\/strong><\/p>\n Between the profiles, 200 mm thick Rockwool AIRROCK ND stone wool is laid, which provides:<\/p>\n * excellent thermal insulation; This layer is a major factor in reducing heating and cooling costs.<\/p>\n 5. Breathable membrane<\/strong><\/p>\n A vapor-permeable membrane is placed on the outside of the structure, which:<\/p>\n * protects the wall from rain and external moisture; This creates a so-called "breathing wall" that maintains a healthy microclimate.<\/p>\n 6. Exterior cladding<\/strong><\/p>\n The final layer is the facade coating, which can be:<\/p>\n * rebated metal panels; In addition to the visual function, this layer protects the building from weather influences and gives it a finished look.<\/p>\n All layers work together as an engineered balanced system:<\/p>\n * the inner layer stops moisture; This principle eliminates:<\/p>\n * condensation in the walls; The result is an energy-efficient house with low maintenance costs.<\/p>\n High energy efficiency<\/strong><\/p>\n The system significantly reduces heating and cooling costs.<\/p>\n Fast construction<\/strong><\/p>\n Construction is many times faster than traditional methods.<\/p>\n Long life<\/strong><\/p>\n Galvanized steel and quality materials guarantee durability over time.<\/p>\n No deformations<\/strong><\/p>\n There are no problems such as shrinkage, cracking or twisting.<\/p>\n Excellent noise insulation<\/strong><\/p>\n Stone wool significantly reduces external noise.<\/p>\n Design flexibility<\/strong><\/p>\n Possibility of different facade solutions and a modern look.<\/p>\n The LSTK construction is ideal for:<\/p>\n * single-family houses; It is especially suitable for people looking for fast, high-quality and energy-efficient construction.<\/p>\n How long does it take to build a LSTK house?<\/strong><\/p>\n Depending on the project \u2013 between 2 and 4 months for the construction and basic finishing works.<\/p>\n Is the structure sustainable?<\/strong><\/p>\n Yes, the metal structure is designed to withstand serious loads and climatic conditions.<\/p>\n Is there a risk of condensation?<\/strong><\/p>\n No, thanks to properly arranged layers and membranes.<\/p>\n What is the insulation?<\/strong><\/p>\n 200 mm thick rock wool is used, which provides excellent performance.<\/p>\n Our LSTK construction is a modern solution for modern construction, combining strength, efficiency and comfort. Each layer has its own function and together they create a system that works long-term and reliably.<\/p>\n If you are looking for a house with low costs, fast implementation and high quality, LSTK technology is the right choice.<\/p>","protected":false},"excerpt":{"rendered":" Modern construction in Bulgaria is increasingly moving towards energy-efficient, fast and reliable solutions, with one of the most preferred being the construction of houses from light steel structures (LSTS).
