Energy Efficiency for Ottawa's Climate
Ottawa experiences some of Canada' most extreme temperature swings—from -30°C winters to +35°C summers. Windows are a major source of heat loss and gain, but Alta Honeycomb Shades fight back.
How honeycomb cells work:
- Air pockets trap air at the window surface
- Creates an insulating barrier against temperature transfer
- Reduces heating costs in winter
- Blocks solar heat gain in summer
- Decreases strain on HVAC systems
The R-value (insulation rating) increases with cell size and configuration. Double cell construction offers maximum insulation for Ottawa's harsh climate.
Cell Sizes & Configurations
Alta offers multiple cell sizes to suit different windows and priorities:
Single Cell
- ⅜" cell – Compact, ideal for smaller windows
- ¾" cell – Most popular, balanced proportion
- 1¼" cell – Larger windows, contemporary look
Double Cell (Architella-style)
- Two layers of cells for maximum insulation. The honeycomb-within honeycomb design dramatically increases R-value—ideal for Ottawa's extreme temperatures.
Choosing Your Cell Size:
- Smaller cells suit smaller windows and traditional proportions
- Larger cells work on picture windows and modern spaces
- Double cells prioritize energy efficiency over stack height
Our specialists will recommend the right configuration.
