Energy-efficient prefabricated houses

Prefabricated houses
Prefab elements of the house (walls, ceilings, roof truss) are produced in a manufacturing hall. This solution is better than traditional construction because:
The production of medium-sized house prefabricates takes from several to several dozen days. Their assembly on the construction site is only a few hours of work. That is why the technology of prefabricated wooden houses is gaining more and more supporters.
- It significantly speeds up the construction of the house.
- Weather conditions (rain, snow) do not affect the production process.
- The house elements are made very precisely, which facilitates further finishing.

WALLS
- The wall structure is pressed on a pneumatic table, which gives it exceptional compactness and rigidity.
- The prepared frame is reinforced on both sides with structural panels.
- The interior of the wall is filled with a layer of thermal insulation made of mineral wool. Channels for electrical installation and spaces for plumbing installation are prepared.
- And for central heating.
- Following the principles of warm installation and using expansion seals and special collars, windows and external sills are installed in the walls.
- A layer of thermal insulation (e.g., polystyrene with adhesive and mesh) is installed on the external walls of the building.
CEILINGS
- The wooden beams are cut accordingly.
- According to workshop drawings and screwed together.
- So as to create ceiling panels.
- A structural MFP or OSB board is then screwed to the prepared wooden frame.
- The ceilings are then filled with acoustic insulation made of mineral wool.
- A wooden grid for plasterboard panels is nailed to the ceiling structure. The panels are installed on-site after installation work is completed.
ROOF
- The wooden beams for the roof construction are cut according to workshop drawings.
- Visible elements of the roof structure.
- Are sanded and painted in the production hall.
- Locks and mounting holes are made in the roof elements.
- The roof structure is assembled directly on the construction site.

PARTITIONS
Cross-section of an external wall
1. GKFi board - eliminates the need for additional internal wall plastering, eliminating wet work and drying requirements, as in the case of traditional plaster.
2. Vapor barrier - prevents moisture from penetrating from the interior into the partition. This protects the structural wood and mineral wool insulation material from moisture (wet insulation loses its thermal insulation properties).
3. V100/MFP/OSB3 board - protects the structure from moisture, stiffens the construction, strengthens the wall, eliminating issues with nail, screw, and dowel fixation.
4. Wooden load-bearing structure - using this solution allows for filling the entire space between the beams with non-combustible mineral wool insulation material. Therefore, it is possible to achieve the highest thermal insulation parameters for our partitions, making our homes energy-efficient.
5. Mineral wool - provides excellent thermal and acoustic insulation. Thanks to its flexibility and elasticity, it perfectly fills the space between the beams, eliminating all types of linear and point thermal bridges that negatively affect the thermal insulation parameter of the partition.
6. V100/MFP/OSB3 board - serves as a load-bearing layer for the second layer of insulation made of polystyrene or optionally mineral wool and stiffens the structure.
7. Adhesive for external insulation - used to adhere polystyrene or wool to the V100/MFP/OSB3 board.
8. External insulation - serves as the second layer of insulation, further improving the partition's insulation properties.
9. Mesh-reinforced undercoat - a reinforced layer under thin-layer plaster.
10. Plaster - external facade layer (not included in delivery).

Cross-section of an inter-floor ceiling
1. Floor finishing - any finish such as wooden floor, terracotta, laminate flooring.
2. Concrete screed - adds weight to the ceiling, improving its acoustic properties and allowing for the laying of any floor finish.
3. Styrofoam - provides acoustic insulation from impact noise, allows for the installation of utilities such as water, electrical, central heating beneath the screed layer.
4. Building foil - protects against moisture ingress into the structure.
5. V100/MFP/OSB3 board - evenly distributes the load onto the floor beams.
6. Floor beams - structural element of the ceiling, allows for filling the space between beams with acoustic insulation.
7. Mineral wool - acoustic insulation, serves as thermal insulation during transitional periods when the upper floor is unfinished and only the ground floor is heated.
8. Vapor barrier foil - prevents moisture from penetrating into the ceiling structure, especially when only the ground floor is heated.
9. Supporting grid for gypsum fiberboard (GKF) panels.
