The implementation of a passive house requires the use of special building materials that will pay off in the future with low bills. Learn about our next project, this time a single-family passive house.
Energetic Project with its team visited Michalowice, where Ms. Olga and her husband have set their sights on a passive house with a floor area of 182 m2.
Foundations
They relied on traditional foundations built with footings and footings. They were made of C16/20 concrete.Sand backfill and drainage drainage were used. The foundation walls were built of 24 cm thick concrete blocks with cement mortar.
Damp proofing was applied. Coating insulation was laid, followed by 0.2 mm x3 PE film. In 85 m2, the bucket film was laid, and 22.59 m2 of foundation walls were covered with waterproofing membrane.
20 cm extruded polystyrene foam was also laid to insulate the foundation.
Walls, windows, doors
External structural walls were made using the IZODOM technique. Using this material, 168 m2 of exterior walls were erected.
The partition and interior walls were made of Porotherm bricks, but this time in a different thickness: 11.5 cm and 8 cm. A total of 130 m2 of partition walls and 39.79 m2 of interior walls.
The walls were insulated with 30 cm thick polystyrene foam and finished with thin-coat silicone plaster.
Triple-glazed, energy-efficient windows, totaling nearly 47 m2. Six pieces of energy-efficient roof windows were also placed. One exterior door, one interior door with skylight, and 12 interior doors were put in. The garage door, as befits a passive building, insulated, Segmented, in a warm assembly.
First floor and ceiling over first floor
A 10 cm thick lean concrete base was poured, and 3x 0.2 mm PE foil was spread on it. The first floor screed was made of C12/15 concrete, armed with steel mesh and insulated with 20 cm thick polystyrene foam. The whole was covered with 2 cm of flooring.
A 25×25 cm reinforced rim was poured over the walls. The floor above the first floor was created from an 18 cm thick reinforced concrete slab, with 14 cm polystyrene foam put in place, screed reinforced with 3 mm mesh and 0.2 mm PE film. The whole was covered with a 2 cm floor.
On the first floor we find a garage, a study room, boiler rooms, a toilet, a kitchen with a pantry, a living room with a dining room, as well as a hallway and a lobby. From the living room we can go out to the terrace.
Attic and roof
The attic floor was finished with a ceiling, built with GK boards (1.25 cm), vapor barrier film, a steel frame for GK boards, a 5×20 wood beam with 20 cm PUR foam and a 2 cm OSB board with PE film.
The attic features a large bedroom with a walk-in closet, two bathrooms and two bedrooms. There was also room for a laundry room.
Outside you will find two balconies with a beautiful view, measuring 8.5m x 3m and 6.5m x 1.2m, which have been protected with polystyrene foam (20 cm), heat-weldable membrane, liquid film for outdoor terraces and a two-centimeter frost-resistant terra cotta floor.
Roof
The roof was built with 7×20 cm rafters with 20 cm thick PUR foam on “wires”. Underneath, a vapor barrier film reinforced with mesh was applied. In the living area it was encased in plasterboard, on an established steel frame for plasterboard.
Under the 2x5cm counter-battens, a vapor-permeable film was applied to the outside, and full boarding was laid, with 5x6cm battens. The roof was covered with ceramic tiles.
Installations and driveway
The entire house is heated with Termofol heating mats. Recuperation was also used to recover heat from the exhaust air to the incoming air. In addition, air conditioning was installed in the attic to cool down on hot days.
In front of the house, Bruk-Bet paving stones were laid on an area of about 50 sqm for convenient access and access to the outer door.
