Uniquely short construction timelines for Canadian homes, independent of the time of year.
It takes only 2 – 3 months from selecting an off-the-shelf design or developing a custom one to finish, depending on the scope of work. Manufacturing a set of sandwich panels, their delivery to the construction site and installation takes only 10 – 15 days. The rest of the time is spent on manufacturing the foundation, installation of windows, stairs, doors, and roof, wiring, and installation of utilities, production of external and internal finishing.
Lack of a heavy foundation.
Unlike buildings built on traditional technologies, the Canadian houses of structured sandwich panels with the same or better consumer properties do not require a complex and expensive foundation. Given the strength of frameless structures and their relative lightness (about 17 kilograms per square meter), it is possible to use small foundation blocks, lightweight strip foundation, or metal screw piles as a foundation.
The highest energy-saving features..
Panels have high energy saving characteristics (ten times higher than in buildings made of brick and concrete), so the operating costs and especially heating costs are several times lower compared to brick ones, which is very important in conditions of the constant growth of prices for energy and organization of autonomous energy supply. In terms of heat-saving characteristics of the 15 cm wall of the structural insulating panel is superior to the 150 cm brick wall. Sandwich houses with 30 centimeters thick panels, even without heating, do not freeze in the strongest Arctic frosts.
ECO materials.
The starting materials for the manufacture of the panels are oriented chipboard OSB-3, polystyrene foam (polystyrene foam) as an insulator, and polyurethane adhesive, which gives the panels exceptional strength. Also, the glued beam is used to connect the sandwich panels. Oriented chipboard is a product of wood origin. It is formed by pressing rectangular wood chips under high pressure and temperature, using a water-resistant synthetic resin as an adhesive. Styrofoam is an environmentally friendly material with exceptionally high heat-saving characteristics. The bonding mortar is a polyurethane adhesive, completely harmless in use.
Mobility and autonomy of construction.
Since the kits of the Canadian houses are completely manufactured in factories and have lightweight, they are assembled and adjusted on-site by a team of 4 people, no construction equipment and mechanisms are required. There is no obligation to be connected to the power generating capacities and bases of construction materials, which allows conducting construction in isolated, remote, or hard-to-reach places. Besides, short assembly terms, minimum requirements to the foundation and almost total absence of special construction equipment and sites allow to construct low-rise buildings (up to 3 floors) with any technical and operational characteristics in places with complicated or limited assembly conditions. Such as point development in the existing infrastructure, architectural and archaeological monuments and reserves, complex soils, sites on engineering communications, and overpasses.
Low cost of construction.
The cost of the construction of the building frame for finishing with all floors, rough floors, partitions, and the roof (without roofing) on the proposed technology, including the cost of the project, the manufacture of a set of sandwich panels, its delivery, and installation, is comparable to the cost of the frame of the beam, but in its technical and operational parameters repeatedly superior to the buildings of brick or block.
The versatility of sandwich panels.
Structures made of sandwich panels can be manufactured in any architectural form and with any quality of finish, depending on the requirements of the building, ranging from outbuildings, garages, or cottages, and ending with 3 – 4 story townhouses and cottages. When building and finishing, they are compatible with all the materials, engineering systems, and life support complexes on the market. The frame, assembled from sandwich panels, is ready for external and internal finishing, installation of windows, doors, stairs, and roofing without additional preparation.
Excellent consumer properties.
In terms of heat-saving characteristics and sound-permeability, exterior walls and interior partitions made of structural thermal insulation panels are an order of magnitude superior to thicker walls made of bricks or concrete blocks. The thermal transmission coefficient is not less than U = 0.18 (W/m2K). Sandwich houses, complete with double-glazed windows and high-quality doors do not freeze with minimal heating even in the most severe frosts. When the panels are combined into a single building system, they have virtually no technological joints and gaps and create a very strong structure that can withstand a horizontal load up to 3000 kilograms per square meter and a vertical load up to 30 tons per square meter. Structural insulating panel houses are designed to last for up to a hundred years. They are moisture-resistant and resistant to adverse weather conditions, withstanding temperature fluctuations from minus 50 to plus 50 degrees, the maximum snow load, hurricane winds, and earthquakes of up to eight points. You can live comfortably in them even in the most extreme natural conditions. The panels have successfully passed comprehensive fire safety tests.
