Case Study: Full-Home Window Upgrade in Kelowna
Overview
Set in the scenic Glenmore area of Kelowna, this two-storey family home needed a full window replacement to improve energy performance and modernize the look of the property. The original windows were beginning to show signs of failure—foggy panes, poor insulation, and difficulty opening and closing.
The homeowners reached out to AlphaTech Windows & Doors to help enhance their home’s efficiency, curb appeal, and comfort.
Project Objectives
- Replace all windows with modern, energy-efficient models
- Improve temperature regulation for both summer and winter seasons
- Enhance exterior appearance while keeping within the existing design
- Maximize long-term durability and minimize future maintenance
The AlphaTech Solution
We began with a thorough assessment of the home, followed by a custom measurement and design process. Each window was manufactured to fit the existing openings perfectly—no cutting corners, no patchwork.
Key upgrades included:
- Energy-efficient double-pane Low-E glass units with argon gas for thermal insulation
- Slim-profile vinyl frames in a neutral tone that matched the siding
- Full perimeter weather-sealing to eliminate air infiltration
- A mix of fixed, slider, and casement windows to balance style and airflow
Tailored for Kelowna’s Climate
Kelowna’s Okanagan climate presents a unique challenge: hot summers, cold winters, and occasional wind exposure. The new windows were selected to perform well across all seasons:
- Low-E coatings help block excess summer heat and damaging UV rays
- Double-pane units retain indoor warmth during winter without the cost of triple-pane
- Ventilating sliders improve airflow during spring and fall shoulder seasons
