In Yellowknife, where winter temperatures regularly dip to extremes, window selection and installation become critical to comfortable living. According to the Canada Weather Service, the city experiences more than 220 days of below-freezing temperatures each year.
Peculiarities of glazing in the Far North conditions
Extremely low temperatures place special demands on translucent constructions. Research by the National Research Council of Canada (NRC) shows that at -40°C, the difference between the temperature at the window and in the center of the room should not exceed 2-3°C to ensure comfortable living conditions.
Frost protection technologies
Modern window replacement in the North involves the use of special technologies:
- Multi-chambered profile with thermal bridges.
- Triple glazing with Krypton filling.
- Thermally insulated spacer frames.
- Special frost-resistant seals.
- Reinforced condensate drainage system.
Specifics of installation in permafrost conditions
The window installation company must take into account the peculiarities of the northern climate during installation. Fasteners are selected taking into account the thermal expansion of materials at extreme temperature differences. Special frost-resistant assembly foams with operating temperatures down to -60°C are used.
Innovative heat-saving technologies
The use of insulating glass units with Low-E coating allows up to 90% of infrared radiation to be reflected back into the room. The inter-glass space is filled with krypton, which is 46% more efficient than argon at extremely low temperatures.
Condensate control in Northern conditions
When installing windows in the Far North, special attention is paid to ventilation and prevention of condensation. Special air inlets with heated air and forced ventilation systems for window jambs are used.
Energy balance of windows
According to research by the Canadian Centre for Housing Technology (CMHC), properly selected and installed windows can reduce heat loss by 35-40% compared to standard designs. This is especially important for heating costs in northern regions.
Protection against snow loads
Window constructions for northern regions are designed taking into account increased snow loads. Reinforced imposts and special reinforcement systems ensure resistance to snow pressure on horizontal elements of structures.
Frost-resistant fittings
Special fittings with frost-resistant lubricants and anti-corrosion coating are used for extremely low temperatures. The locking mechanisms are tested for performance at temperatures down to -50°C.
Thermal resistance of structures
Modern window systems for northern regions provide a heat transfer resistance coefficient of R-7 or higher, which meets the most stringent requirements of Canada’s energy code for northern territories.
Adaptation to the polar night
In conditions of long polar night, the light transmittance of glazing is of particular importance. Modern energy-saving glass ensures maximum visible light transmission with minimal heat loss.
