Drayton Valley, located in central Alberta, is characterized by a continental climate with extreme temperature fluctuations from +35°C in summer to -40°C in winter. The city is observed to experience more than 200 freeze-thaw cycles per year, which places severe stresses on building structures.
Technical requirements for translucent structures
The National Building Code of Canada (NBC) and local Alberta regulations (ABC 2014) require that windows and doors in Drayton Valley meet the following specifications:
- Heat transfer resistance (R-value) not less than 3.3 for windows and 2.9 for doors.
- Heat transmittance coefficient (U-factor) not more than 1.67 W/(m²-K).
- Solar factor (SHGC) in the range of 0.25-0.4.
- Air permeability class A3 (less than 0.34 l/s/m²).
- Water resistance class B7 (550 Pa).

Technical solutions for extreme climates
Modern glazing for the climatic conditions of Alberta is based on advanced technological solutions. The basis of the construction is energy-efficient glass with Low-E low-emission coating. The inter-glass space is filled with inert gas argon with a concentration of 90%. Distance frames are made of high-tech composite materials. The profile system is a multi-chamber PVC profile with a thermal break providing maximum thermal insulation.
Features of the door design
Garden and patio doors at Canglow are fitted with a multi-point locking system and reinforced 2.5mm thick steel inserts to resist thermal deformation. The 52mm thick double-glazed units are filled with krypton, providing a heat transfer resistance of up to 1.1 W/(m²-K). All constructions are NAFS-11 certified for Zone C.
Peculiarities of window installation
Installation of window constructions in Drayton Valley conditions is carried out in strict accordance with CSA A440.4-19 standard. The technology involves the use of vapor barrier tapes with standardized vapor permeability. The installation joint is filled with specialized foam with a density of 25 kg/m³. The outer contour is sealed with weather-resistant materials. The final stage is the mandatory installation of sills and soffits protecting the installation joint from atmospheric influences.
Addressing typical problems of continental climate
To prevent freezing and condensation, the innovative Warm Edge system with composite distance frames is used. The special drainage system with frost-resistant valves can operate at temperatures down to -45°C. EPDM-rubber seals retain their elasticity from -50°C to +120°C.
Energy efficiency and payback
According to research, installing windows and doors in Drayton Valley conditions provides energy savings of up to 2,840 kWh per year. At current heating rates, this represents a cost savings of 380-420 CAD annually. Canglow products meet the criteria of Alberta’s Energy Efficiency Alberta program.
Durability and environmental friendliness
Independent testing in a climatic chamber confirms the retention of characteristics after 1500 cycles of temperature and humidity exposure. The profile system is environmentally certified by Vinyl Council Canada and does not contain lead stabilizers. The production is ISO 14001:2015 certified, which confirms compliance with environmental standards.
Warranties and certification
All Canglow products have the necessary certificates. The company provides an extended 25-year warranty on double-glazed units, subject to professional installation by certified specialists.
FAQs
The time depends on the scope of work and the complexity of the project. On average, window replacement in a typical apartment can take 1-2 days. For a private house, the process may take 3-5 days. However, large or complex projects may require more time. It is better to discuss exact terms with our managers.
Yes, it can be done at any time of the year, including winter. Modern technology and materials allow work to be carried out even at low temperatures. However, winter installation requires additional precautions and may take a little longer. The advantage of winter replacement is the ability to immediately assess the quality of the thermal insulation of the new windows.
The main signs that it’s time to upgrade your windows:
- Drafts and heat loss.
- Condensation between the panes.
- Difficulty opening and closing.
- Visible damage to frames or glass.
- Increased noise from the street.
- Significant increase in heating bills.
Yes, quality replacement windows can increase property values. New energy efficient windows make a home more attractive to potential buyers because they promise savings on utility bills and increased comfort. By some estimates, replacing windows can increase property values by 5-10%.
Usually the windows themselves (profile and double-glazed units) are guaranteed for 3 to 5 years. The installation work is usually guaranteed for 1 to 3 years.
