Low-energy prefabricated houses

The systems we use to construct low-energy prefabricated houses are Standard, Euro, EuroMAX and Mega.

EXTERNAL WALLS - constructed in the Standard, Euro, EuroMAX and Mega systems.

*** System EuroMAX ***                 d= 40,0 cm
The core of the wall is a load-bearing construction made of glued laminated wood, d=20, sheathed on both sides with a gypsum fiber - fermacell panel d=1.25 cm. It is filled with rock wool d=20, which has a Delta-Dawi water membrane on the inside, and a Delta-Maxx windproof/vapor permeable membrane on the exterior. Spacing is installed on the gypsum fiber-fermacell board on the interior: a wooden construction d=5 cm with rock wool insulation filler d=5 cm closed off with a gypsum fiber-fermacell board d=1.5 cm. On the exterior gypsum fiber-fermacell board, a vapor permeable polystyrene board, d=10, is installed, which is coated in construction glue, and silica stucco as a final finish.

System Standard                 U=0,14 W/m²K,
zid  d= 30,6 cm

The wall elements are produced with impregnated load-bearing wooden constructions - KVH, 16 cm wide, which are sheathed on both sides with gypsum fiber - fermacell boards d=1.25 cm (or OSB board), filled with rock wool d=16, with a vapor membrane. Gypsum fiber - fermacell boards d=1.25 cm are installed on the interior walls, and the exterior walls are boarded with polystyrene d=10 cm, coated with construction glue with netting, and finished with silica stucco.

System Euro                 U=0,118 W/m²K,
zid  d= 36,8 cm

Variant 1:  The wall elements are produced with impregnated load-bearing wooden constructions - KVH, 16 cm wide, filled with rock wool d=16 cm, with a Delta Dawi GP vapor membrane. On the exterior, gypsum fiber - fermacell boards d=1.25 cm are installed, while OSB boards d=1.2 cm are installed on the interior walls. A spacing construction is constructed on the OSB board d=5 cm, filled with rock wool d=5 cm, with a gypsum fiber board d=1.25 cm + gypsum board d=1.25 cm. The exterior walls are boarded with polystyrene d=10 cm, coated with construction glue with netting, and finished with silica stucco.

Variant 2: Wooden load-bearing construction - KVH, d=20 cm filled with rock wool d=20 cm with a vapor membrane, sheathed with gypsum fiber board d=1.25 cm (or OSB board) on both sides. On the interior, gypsum board is installed over the gypsum fiber board, and the exterior walls are boarded with polystyrene d=10, coated with construction glue with netting, and finished with silica stucco. The total thickness of the Euro wall, variant 2 d=33.50 cm, and the heat transferal coefficient is U=0.123 W/m²K.

System Mega                 U=0,093 W/m²K,
zid  d= 45,8 cm
  PASSIVE HOUSE WALL
The wall elements are produced from impregnated load-bearing wooden constructions - KVH, 22 cm wide, insulated with rock wool d=22 cm, and a Delta Dawi GP vapor membrane. A gypsum fiber - fermacell board d=1.25 cm is installed on the exterior over the wooden load-bearing construction, while the interior is sheathed with OSB d=1.2 cm. A spacing construction is installed on top of the OSB board - a wooden construction d=8 cm, insulated with rock wool d=8 cm, which is sheathed with a gypsum fiber - fermacell board d=1.25 cm + gypsum board d=1.25 cm. The exterior walls are boarded with polystyrene d=10, coated with construction glue with netting, and finished with silica stucco.

INTERNAL WALLS
The wall elements are produced with impregnated load-bearing wooden constructions 10 and 12 cm wide, filled with rock wool d=6 cm (or more), sheathed with gypsum fiber board d=1.25 cm (or OSB board) on both sides, with another layer of gypsum board d=1.25 cm. The total thickness of the non-load-bearing walls is d=15 and 17 cm.

WALL HEIGHT
The standard height of wall elements is 2.70 m, and if necessary, the walls can be constructed taller. The interior height from floor to ceiling with the standard wall construction is 2.56 m, depending on the height of the floor construction. 

FLOOR CONSTRUCTION
Constructed of KVH joists, with dimensions and spacing according to the static calculation, with mineral wool d=10 cm, and d=20 in overhangs. On the bottom, lathing is installed to which fireproof gypsum board d=1.25 cm. OSB board d=1.8 cm is installed on the top side, which then receives sound insulation, cement screed, and a final flooring finish, depending on the use of the space.

CEILING CONSTRUCTION
The ceiling construction for single-level and multilevel homes is the bottom of the roof truss, which is covered in lathe, and fireproof gypsum board d=1.25 cm, filled with mineral wool of a thickness in accordance with the thermal calculation with a vapor membrane. The ceiling construction for houses with an attic: mineral wool with a vapor membrane in the roof slope, and the central dropped ceiling, with lathe and fireproof gypsum board d=1.25 cm.
The thickness of mineral wool according to construction system: d=20 cm - Standard, d=25 cm - Euro and Mega.

ROOF CONSTRUCTION
The roof construction for single level homes and multi-level homes are wooden trusses, or if the attic is usable, then classic wooden constructions are used. The roof construction for single-level homes with attics is the classic wooden construction which consists of rafters and purlins.
