Light Steel Frame Construction

CONSTRUCTION STANDARDS OF ACERO FRAME HOUSES

Light Steel Frame Construction technology allows to erect any type of building: single- and multi-family houses, schools, hospitals, commercial or industrial buildings, warehouses, gazebos, garages, sports facilities, shop floors, workshops, logistics centers, car showrooms and service stations, social facilities, exhibition halls, buildings intended for farming purposes, barns, canopies and other.

At the stage of designing the house, we care about the appropriate location so that it is possible to generate solar energy. It is most preferred for the biggest elevation to face south and to be glazed to the greatest extent possible.

We want the body of Acero Frame energy-efficient house to be rigid; however, proper arrangement of rooms is equally important. Living rooms should be located in the sunny part of the building. Kitchen, bedroom, bathroom and utility rooms should be located in the north and east. Good design is an investment that in the future will enable to minimize operating costs.

Building partitions as well as materials used for their construction have the biggest impact on building’s energy efficiency. The largest energy losses occur in wall, roof and slab partitions, so these are the areas that we pay special attention to. We carefully select components such as windows and doors and various insulating materials such as wool, polystyrene, vapor barrier films as well as insulation and assembly tapes. That is why our houses are created as one compact, rigid and energy-efficient body. Starting from the ground – we create energy-efficient ground slabs ensuring heat transfer coefficient of 0.16 to 0.11 W / m2K. Our walls guarantee rates of U = 0.19 to 0.14 W / m2K while roofs and slabs of U = 0.20 to 0.16 W / m2K. For demanding clients we offer passive partition walls of U=0,1 W/m2K heat transfer coefficient!

Windows generate heat losses up to 40%. Therefore, we recommend high-quality windows and doors at the level of U = 1.1 to 0.5 W / m 2 K. As one of the few companies we do “warm assembly” of windows and doors on complete tape and sealants systems. As far as the whole concept of tightness and enegy-efficiency is concerned, this is extremely important.

Our houses are designed in such a way as to completely eliminate thermal bridges within the connections in construction, windows and doors as well as shutters. Individual projects are thoroughly analysed in terms of construction and insulation. Research team of Warsaw University of Technology constitutes our support in developing project’s details.

Assembly works are carried out only by assembly teams, which have appropriate experience, are adequately trained. It is necessary to preserve insulation of a house, its tightness and quality.

Heating devices in Acero Frame energy efficient houses used for heating and preparing domestic hot water are based on the latest solutions, i.e. condensing boilers and heat pumps. These installations are extremely effective and can generate a significant amount of heat at reduced costs. In our houses we mostly design floor installations based on low temperature parameter, which guarantees savings and also offers an ideal temperature and warmth. We use mechanical ventilation, which provide a constant flow of air that is independent of weather conditions. To minimize energy loss and provide proper comfort, we combine mechanical ventilation with heat exchanger for the purpose of recovery of the heat.

We will obtain very good tightness of the building and healthy room temperature through an appropriate design of the building, selection of best solutions and materials as well as meticulous execution. Therefore, during construction phase, we carry out a so-called pressure test. During this test we measure tightness of the building, which in turn enables us to confirm the tightness that we guarantee. As one of the few companies we confirm guaranteed parameters and tightness, which is the essence of a true energy-efficient house. In addition, each time we make pictures of the building using thermal imaging camera.

With rising costs of utilities and decline in natural resources, we should think about optimizing the energy consumption in our homes. By means of our intelligent building system, investors can save on costs of energy carriers which they use in their homes. This system allows full media monitoring, managing and optimization. You can optimally manage the heating, ventilation, lighting and other utilities in your home. Intelligent building management system will free you from these activities, so that you can dedicate yourself to what you really care for.

Proces budowy

  • Paving the building and excavation
  • Arrangement of elements: external sewage and optional ground heat exchanger
  • Applying geotextile on the entire excavation intended for separation of the land
  • In the case of high groundwater level – laying the drainage system with an inspection chamber
  • Filling the excavate with sand and gravel mix (permeable aggregate) and its corresponding concentration
  • Laying and assembling thermal insulation fittings (vertical and horizontal), serving also as shuttering for pouring the concrete. Places where vertical installations penetrate thermal insulation are additionally sealed with special foam
  • Laying the reinforcement of reinforced concrete slab
  • Optional arrangement of radiant heating and water system
  • Installation of consoles for guide rails intended for levelling the slab. Reinforced concrete slab for framework must be perfectly straight (high tolerance is of 5 mm for 10 m)
  • Pouring the concrete on a shuttering. During this process, we constantly thicken the concrete
  • We can use fiber-reinforced concrete, which replaces the traditional steel reinforcement
  • After the initial hardening of the concrete, we additionally make places where walls are built the same height
  • We assemble the walls of the reinforced concrete slab using special anchors
  • In places where structure of reinforced concrete slab meet we use special sealing foam (dilation suppresses vibrations between materials that differ in terms of physical properties)
  • We connect walls using self-drilling screws
  • Foams are also used in every junction point between steel elements of the walls and slab/ flat roof / roof
  • In the case of roof / flat roof we install waterproof tongue and groove panels on the steel construction
  • After assembly of the entire steel structure, we build prefabricated chimneys
  • Installation of roof windows and roof hatches
  • Application of vapor-permeable foil
  • Installation of batters and counter-batters
  • Application of the final roofing: metal tile sheets, roof sheets, clay roof tiles, concrete roof tiles
  • Installation of flashing and guttering system
  • In the case of bitumen roofing shingles we put waterproof tongue and groove panels on counter battens
  • In the case of a flat roof we put trapezoidal sheet on a steel construction. On top we apply pitched hard insulation. Finally, we put a membrane of the flat roof
  • For steel walls construction we put waterproof glued panels
  • We mechanically install thermal insulation to panels
  • In window openings we execute warm installation of windows by using: wind and vapor barrier tapes as well as expanding tapes
  • Installation of external window sills
  • On top of the insulation we put plaster system
  • Installation of PVC roofing panels – optionally wooden ones
  • Filling the walls construction by using thermal insulation
  • The system allows free use of any finishing materials: clinker, clinker tiles, ceramic tiles, stone tiles, sandstone, wood, composite material, steel panels, aluminium panels, etc.
  • Mechanical ventilation
  • Electrical system
  • Installation of hot and cold water
  • Installation of internal sewage system
  • Installation of traditional radiator central heating system, optional radiant heating or mixed Heating systems (on the ground floor underfloor heating, upstairs – traditional radiator heating)
  • Optional installation of central vacuum cleaner and solar installation
  • For steel construction we use vapor barrier films
  • Finally, we install plasterboards filled in the connection points, ready to paint
  • Filling walls construction with glass wool, which acts as sound insulation
  • Finally, double-sided finishing of the walls in the form of plasterboards filled in the connection points, ready to paint
  • For steel construction of a slab we put trapezoidal sheets from the top
  • On top of the panels, we put an even layer of floor covering
