LIGHT GAUGE STEEL FRAME HOUSES

We are proposing you  the best quality of materials at an affordable price. Here you will be able to follow the building process and find the proof for the standards of our company.

Basement foundation is with 40 cm thickness. Nylon is applied underneath. Within the price we include, kaloubi, reinforcement shara on 2 levels Y 12/15 quality. Concrete is with quality B500 C.Above the concrete after installation of electricity and plumbing pipes, we apply XPS polystyrene of 3 cm for damp insulation and on top – screed 10 cm with quality C25

For foundations under the level of the ground we apply the following insulations:

  • Flint coat

  • Bitumen felt 4 mm

  • Damp proof membrane – 5 mm

Skeleton of the construction

 

The skeleton of the construction is realized with light gauge steel frame with the technology of the company FRAMECAD from New Zealand.C sections with the following sizes are used for the different walls

 

Interior walls and between floor structure – C89mm x 41mm x 0.75mm and C89mm x 41mm

Exterior walls – C150mm x 41mm x 1.15mm

 

Steel is galvanized and ensures a long lasting skeleton with a life more than 100 years. The steel frame is installed and screwed to the concrete slab, construction process will take approximately 2-3 weeks. Galvanized steel structure does not get corrosion; therefore the security of the structure is more than 100 year. Weather conditions can not cause any contraction, distortion, splitting or twisting of the steel. Galvanized-metal structure is much more resistant to fire, keeping structural integrity longer. Contains no harmful chemicals for the maintenance of wood, and pesticides and ingredients which may cause allergies. Resistant to fungal attacks and does not require any expensive and toxic treatment against termites.In case of designs with big open spaces, may be would be required the use of heavy gauge steel columns.

Inside walls

Inside walls are made of:

  • Vidiwall by Knauf – Fiber reinforced gypsum boards – 12.5 mm thickness / Density 1250 kg/m3, Water vapour resistance factor μ ~ 18, Resistance to fire acc. to EN 13501-1 A2 s1d0

  • Steel frame structure 8.9 cm,

  • Inside the metal skeleton we use rock wool insulation 5 cm layer for thermal and sound insulation/Heat conductivity calculation value: λ = 0.040 W/m2K /

  • Vidiwall by Knauf – Fiber reinforced gypsum boards – 12.5 mm thickness / Density 1250 kg/m3, Water vapour resistance factor μ ~ 18, Resistance to fire acc. to EN 13501-1 A2 s1d0

  • Waterproof stucco for connections and walls

  • Stabilizer Paints 

Outside walls:

External walls – from inside to outside: 

  • Vidiwall by Knauf –Fiber reinforced gypsum boards – 12.5 mm thickness / Density 1250 kg/m3, Water vapour resistance factor μ ~ 18, Resistance to fire acc. to EN 13501-1 A2 s1d0

  • Steel frame structure 15 cmBetween the metal structures we install a double layer of 10 cm rock wool, ensuring thermal and sound insulation. /Heat conductivity calculation value: λ = 0.040 W/m2K /

  • OSB waterproof Grade3 – 9mm

  • Vapour membrane

  • Steel structure 3 cm, galvanized /

  • Cement board by Knauf – Aqua Panel – 12.5 mm

  • Net + 2 layers of thermal glue Knauf

  • Stabilizer

  • On the outside the facades can be finished with grafiato or paint according to the requirements of the customer

 

Between floor structure in case of 2 and more floor buildings

The structure of a 2 or more floor houses is presented by 40 cm trusses positioned every 40-50 cm which after that are covered with a metal deck A34/06. After installation of the electrical and plumbing pipes the between floor structure already covered with metal deck is finished with a layer of 7-10 cm concrete, on top of which we are already able to install parquet or tiles, according to the wishes of the customer. Between the floor trusses and the ceiling you will find a layer of sound and thermal insulation of rock wool – 5 cm /Heat conductivity calculation value: λ = 0.040 W/m2K /.

 

  • Trusses 40 cm positioned every 40-50 cm

  • Resilient tape for sound insulation

  • Metal deck A34/06Concrete 7-10 cm

  • Rock wool sound and thermal insulation– 5 cm /Heat conductivity calculation value: λ = 0.040 W/m2K /.

Roof structure

 

As soon as the skeleton of the house is installed and depending on the design of the house, the roof will be closed according to the building specifications. Within the price proposed you have the choice of standard ceramic tiles for your roof / Portuguese and French type/ or a flat roof of light concrete covered with the required insulation. Underneath the roof you will find the metal trusses of 30-40 cm positioned every 40-50 cm which ensure the structural integrity of the roof which are covered with waterproof OSB / class 3/ and a layer of XPS fibran. Between the roof trusses and the ceiling you will find a layer of sound and thermal insulation of rock wool /Heat conductivity calculation value: λ = 0.040 W/m2K

 

Flat roof structure:

  • Trusses 40 cm positioned every 40-50 cm

  • Metal deck A34/06

  • Light Concrete 10 cm

  • Rock wool sound and thermal insulation– 5 cm /Heat conductivity calculation value: λ = 0.040 W/m2K / between the metal structure

  • Cement base insulation – 3 layers or bitumen felt

Pitch roof structure:

  • Trusses positioned every 40-50 cm

  • Waterproof OSB Grade 3 – 11 mm

  • Water membrane – 2mm

  • XPS fibran heat insulation 3 cm

  • Roof tiles /Portuguese and French type/

  • Rock wool sound and thermal insulation– 5 cm /Heat conductivity calculation value: λ = 0.040 W/m2K / between the metal structure

Plumbing installation:

After the roof has been finished we start the installation of the plumbing and electrical systems:Standard polypropylene tubes are built-in the floor and the walls (pipe-in-pipe with rubber of German origin/ . Solar Systemcomprising a pressure cylinder 200 lt in two panels, plastic water tank 1t and water pressure pump are installed.Our cost includes the installation of all sanitary and accessories for the bathrooms and kitchen. Systems are tested and propose a guarantee for the use of high quality materials

Electrical installation:

The electrical installation will be single-phase. Electrical installations are made in accordance with the requirements of AHK and are based on architectural plans.
Within the price you will have provision for air conditioners for each room, Telephone, Internet, Cable TV

 

Switches and sockets included are:
