The lightness and large size of SIP panels makes this material one of the best for the construction of country houses. All the main parts for the construction are produced at the factory, the required amount is brought to the site and assembled as a designer. A large team is not needed for this, a task can be handled by a team of 2-3 people. In addition to the assembly readiness of the material, the simplicity of its docking is also attractive. Consider the key stages of the technology of building a house from SIP panels.
Which foundation is right?
In the case of SIP panels, there is no need for an expensive, powerful base. A finished house using Canadian technology weighs no more than 15 tons, so just select the economical strip foundation. In accordance with building regulations, the foundation is laid on the depth of soil freezing, in our case, it is enough if angular grouts along the entire perimeter are laid at this depth.
Second stage: floor overlap
Assembly of the house from SIW panels is possible at any time of the year; construction does not have wet stages. Installation begins with the installation of floor ceilings. If the span is not more than six meters, standard panels are used for floor ceilings. Insulation of the inside of the panels is carried out with an antiseptic and bitumen mastic.
The joints between the panels are fixed with screws and sealed with foam. To give rigidity to the construction along the horizontal axis, strapping bars are placed in the technological grooves of the ends. Installation of floor ceilings can be completed within a few hours.
Mount the walls
Before starting the installation of the first wall panels, a strapping loop for the walls is prepared. To do this, a longitudinal beam 10 cm thick is attached to the floor with self-tapping screws. The template will help to verify the correctness of its placement. The structure is fixed to the foundation with anchor bolts, drilling holes through panels and beams. All parts must be treated with antimicrobial and water repellents.
The panels that form the corner are mounted first. To the first, the second is placed at right angles. Due to the strong fixation of the corner elements, the structure acquires the necessary rigidity. Next, the panels are mounted in series using a tongue-and-groove connection. The connection of the panels to each other is fixed with self-tapping screws or large ship nails.
When all the panels forming the walls of the first floor took their places, their technological grooves on top are filled with polyurethane foam and closed with strapping boards. Simultaneously with the construction of the perimeter, the space of the first floor is divided into zones by partitions from panels. An additional structural rigidity is provided by the overlap connecting the walls to each other.
The same technological cycle is repeated on the second floor. The ceiling is assembled similarly to the installation of the floor, the frame of the previous floor serves as a support for it, floor slabs are attached to it with self-tapping screws.
Attic and roof: no rafters
Roof mounting is one of the standard technologies for working with SIP panels. Rafters are not needed when erecting a roof; the inherent rigidity of the panels allows them to withstand all meteorological loads.
The lower base for the roof panels is a Mauerlat, fixed around the perimeter, and the top - a ridge beam, fixed between the gables. Stacked panels are attached to the timber at the top and bottom with screws. The fixing of the roof panels to each other occurs similarly to wall elements - self-tapping screws or ship's nails.
The attic located under the roof of SIP panels will always be warm. The design of the panels is such that the roof does not need vapor barrier. The roof can be made of any material known today: bitumen, ceramic or metal tiles, and others.
Sealing the finished house
Having completed the assembly, the structure is sealed, coating all joints with polyurethane adhesive. This is a very important stage, the thoroughness of its implementation ensures long-term operation of the house.
Installation of doors and windows
Openings for doors and windows are provided by the project and prepared in the factory, this greatly simplifies installation.
Exterior and interior home decoration
Outside the house can be faced with brick or siding, lining, timber, natural stone or its artificial imitation. The perfectly smooth inner surface of the walls is also suitable for any finishing materials: wallpaper, staining, tiling and others. The use of drywall will give the walls additional fire resistance.
Engineering Communication
Communications are laid upon completion of the assembly of the frame. All of them will be easily accessible due to their external location. If necessary, they are covered with drywall partitions or suspended ceilings. Water supply and sewerage in a one-story house are made under the floor, special mines are arranged for a two-story building. A distinctive feature of construction using SIP is its flexibility in communications. All wooden elements that will come into contact with water supply and sewage are additionally impregnated with waterproof compounds.
Factory production of all elements, the ease of panels makes installation possible in the shortest possible time.
The advantages of houses from SIW panels compared to houses using traditional construction technologies are obvious:
- Strength. Sip panel can withstand up to 200kg load per 1m2 with a deflection of no more than 12mm.
- No shrinkage and smooth walls. Exterior and interior decoration can be purchased immediately after installation.
- The increased fire resistance. Temperature range from -50ºC to + 50ºC
- Lightweight construction. Canadian home weight average
no more than 15 tons - Increased heat capacity. For heating a house using SIP technology, 4-6 times less resources are needed than for heating a brick.
