Premium Window Solutions
Drafty windows cost you money and make your home uncomfortable. At Transformer Exteriors, we install energy-efficient replacement windows built for Calgary’s extreme cold, strong winds, and temperature swings. Fully licensed, insured, and local.
- Drafts or cold air feeling near windows
- Condensation between glass panes (failed seal)
- Rising energy bills (heating or cooling)
- Difficulty opening, closing, or locking
- Visible rot, warping, or damage to frames
- Outside noise is too loud
- Windows are single-pane (original to older homes)
- Windows over 15–20 years old (vinyl) or 30+ years (wood)
Don’t wait – a drafty window can cost 500 extra per year in heating.
WHY NEW WINDOWS MATTER IN CALGARY
Problem | Consequence | Our Solution |
Drafts & cold spots | High heating bills, discomfort | Triple pane + argon gas |
Condensation between panes | Failed seal, poor insulation | Full frame replacement |
Sticking or rotting frames | Air leaks, water damage | Vinyl or fiberglass frames |
Outside noise | Poor sleep, stress | Laminated or triple pane |
Faded furniture/flooring | UV damage | Low-E glass coating |
Calgary wind | Air infiltration | Professional sealing & flashing |
WINDOW STYLES WE INSTALL
👉 Most popular in Calgary: Casement (best seal) + Picture (max light)
Style | Best For | Key Feature |
Casement | Ventilation + tight seal | Crank opens outward, multipoint lock |
Awning | Rainy climates | Hinged at top, opens outward |
Horizontal Slider | Budget-friendly | Slides left/right, no crank |
Single Hung | Traditional homes | Lower sash opens upward |
Picture / Fixed | Natural light | Does not open, maximum glass |
Curved / Geometric | Architectural interest | Arches, circles, custom shapes |
Rake / Angle | Unique roof lines | Follows roofline angle |
GLASS PACKAGES
| No. | Window Glass Type | Features & Benefits |
| 1 | Double Pane (Standard) | • Two glass layers |
| 2 | Triple Pane (Recommended for Calgary) | Three glass layers with dual argon gas fills, offering better insulation, noise reduction, and less condensation. |
| 3 | Low-E Glass (Included with Both) | Special coating reflects heat indoors, blocks UV rays, and improves comfort during summer and winter. |
| 4 | Laminated Glass (Optional) | Extra security and sound reduction with a protective plastic layer between glass panes. |
For Calgary winters, we strongly recommend triple pane – the upfront cost pays back in energy savings within 5–7 years.
REPAIR VS. REPLACEMENT
| No. | When to Repair ($) | When to Replace ($$$) |
| 1 | Broken hardware such as cranks, locks, or handles | Failed seals causing condensation between panes |
| 2 | Single broken pane without seal failure | Windows over 20 years old |
| 3 | Minor localized frame rot or damage | Noticeable drafts from several feet away |
| 4 | Foggy glass affecting only one pane | Frames with major rot, warping, or structural issues |
| 5 | Small repairs that maintain existing performance | Planning siding or roofing upgrades at the same time |
| 6 | Repairable cosmetic or operational issues | Older single-pane windows with poor insulation |

👉 We’ll advise based on your existing windows.
FRAME MATERIALS
Material | Best For | Lifespan | Pros | Cons |
Vinyl | Most homes | 20–30 years | Affordable, low maintenance, energy efficient | Limited colors |
Fiberglass | Extreme weather | 40–50 years | Strongest, handles Calgary temp swings | More expensive |
Wood | Historic / high-end | 30–40 years | Beautiful, natural insulator | Requires maintenance |
Aluminum | Commercial | 30–40 years | Very strong | Conducts heat/cold |
👉 Our recommendation: Vinyl for most homes (best value). Fiberglass for north-facing or extreme wind areas.
ENERGY PERFORMANCE
In Calgary’s climate (heating-dominated), look for:
Rating | What It Means | Target |
U-Factor | Heat loss (lower = better) | ≤ 1.0 (triple pane) |
SHGC | Solar heat gain | 0.25–0.40 (blocks summer heat) |
ER (Energy Rating) | Overall efficiency (Canada) | ≥ 30 (triple pane) |
👉 All our windows meet or exceed Energy Star Canada requirements for Zone A (Cold).
