Rocky Mountain House, located 988 meters above sea level, has special requirements for window systems. According to the local Alberta Building Code 2019, all windows and doors must be able to withstand wind loads up to 4.3 kPa and temperature variations from -35°C to +35°C. The energy rating of windows for the region must meet the minimum ER-29 per CSA A440.2-14.
Technical characteristics of modern panoramic systems
Modern panoramic doors and windows from Canglow are NAFS-11 (North American Window System Standard) compliant and have the following features:
- Heat transfer coefficient U-value: 0.95-1.08 W/(m²-K).
- Solar heat gain coefficient SHGC: 0.39-0.42.
- Sound insulation: STC 34-38.
- Air permeability resistance: Class A3.
- Water resistance: 700 Pa.

Adaptation to the mountain climate
In the Rocky Mountain House environment, where the average annual rainfall is 495mm, proper window installation with drainage in mind is extremely important.
Patio doors are equipped with special drainage channels with a capacity of up to 8 l/min/m². All double-glazed windows are filled with argon gas with a concentration of 95%, which ensures optimal thermal insulation in case of significant temperature fluctuations.
Maximizing species characteristics
Given their proximity to Banff National Park and scenic views of the Palliser Mountains, modern panoramic systems offer maximum glazing area Frameless corner designs offer up to 270 degrees of viewing angle.
The ceiling heights in typical Rocky Mountain House homes (3.0-3.6m) allow for panoramic doors up to 3.2m high with sash widths up to 2.4m. Canglow’s double glazed garden doors are also well suited to the harsh climate of Rocky Mountain House.
Energy efficiency and comfort
The right windows can reduce heating costs by 25-35% At Rocky Mountain House, where the heating season lasts 220 days, the use of modern windows with Low-E coating and a warm spacer frame can reduce heat loss through the windows by 40-45% compared to standard double-glazed windows.
Multi-chambered profiles with a thermal break of 28-32 mm provide additional thermal insulation, reducing the probability of condensation at extreme temperatures to 0.02%. The used double-glazed units with Cardinal LoE-366 multifunctional coating provide 65% visible light transmission while blocking 95% of ultraviolet radiation. This is especially important to protect the interior from burnout in the high solar activity typical of Rocky Mountain House‘s high-altitude location (2,300 hours of sunshine per year).
The innovative triple contour sealing system with a Q-lon maintains a 99.9% Q-lon durability factor and provides Class A sealing according to ASTM E283. At the same time, the air permeability does not exceed 0.1 m³/(h-m²) at a pressure difference of 50 Pa, which significantly exceeds the requirements of the energy standard R-2000 for the region. Estimated service life of the seals is 22 years while maintaining the original characteristics.
Features of a professional installation
Installation of windows in Rocky Mountain House requires consideration of the seismic activity of the region (zone 1 on the Canadian seismic zoning scale). Installation is carried out using special fasteners designed for seismic loads up to 0.6 g. The use of expansion joints 12-15 mm wide to compensate for temperature deformations is mandatory.
Certification and warranties
All Canglow windows and doors are CSA certified and labeled. Products meet the requirements of the National Building Code of Canada and are backed by a 25 year manufacturer’s warranty on insulating glass units. Installation is performed by certified, licensed professionals.
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.
