Windows that work as hard as Calgary's winters are long.

Premium Lux windows, specified for Calgary's full temperature range and installed with the substrate detailing most contractors skip. Quieter rooms, even temperatures, and the kind of seal that holds through a 90 km/h chinook.

01 · Why it matters

A failing window is the single most felt problem in a Calgary home.

Drafty windows are not just an energy issue. They are the daily reminder that something in the home is not working. The whistle of wind in February. The chill at the baseboard six feet away from the glass. The condensation on the inside pane that should not be there. Calgary homeowners feel a failing window every cold front and every shoulder season, often for years before they replace it.

The deeper problem is what is happening behind the trim. Older window installations frequently have compromised flashing and air leakage paths that work against every other improvement to the home. New high-performance windows installed into the same compromised opening do not solve the problem. They just hide it.

A proper window replacement is a substrate decision as much as a glass decision. Done right, it changes how the entire room feels. Done wrong, the new window is just a slightly better version of the old draft.

02 · The EnerClear approach

The glass is half the job. The opening is the other half.

After decades of installing windows in Calgary homes, Sean has settled on one manufacturer. Lux is it. The product specification matters, but it is not what separates a Calgary window installation that lasts thirty years from one that fails in seven.

What separates them is the rough opening. Before any new window goes in, EnerClear inspects the framing and sheathing around the existing opening. We address rot, re-detail flashing, restore the air-seal continuity, and confirm the rough opening is square and properly sized for the new unit. Only then does the window go in.

That sequence is what delivers the comfort homeowners expect from a premium replacement. New glass alone closes maybe half the gap. The substrate detailing closes the rest.

03 · Why Lux

One manufacturer, specified for Calgary's full temperature range.

Not every window product is built for Calgary's climate. Lux is. After decades of testing options across hundreds of homes, EnerClear specifies Lux because it consistently outperforms competing brands on the metrics that matter in Calgary: thermal performance through extreme temperature swings, seal integrity under chinook pressure differentials, and long-term resistance to UV and freeze-thaw stress on the gasket systems. Lux also stands behind what they sell: responsive customer service, fast warranty support, and a long-term commitment that means the windows you install today are backed for years to come.

Window 01 · Primary

Lux triple-pane vinyl.

Our primary recommendation for most Calgary homes. Excellent thermal performance, low-maintenance, available in a full range of operating styles and finishes. Engineered for Calgary's full −40°C to +35°C range.

Window 02 · Premium alt

Lux Hybrid systems: PVC interior, metal-clad exterior.

A premium alternative for homeowners who want the look of painted wood with the performance of an engineered frame. Higher dimensional stability than vinyl in extreme heat or cold.

Window 03 · Architectural

Specialty and architectural glazing.

Where the home calls for it: large fixed picture windows, custom shapes, integrated patio door systems, and specified glazing for solar gain or noise control. Sourced through Lux when possible, through specified manufacturers when the application requires it.

04 · What you gain

What a quality window installation delivers.

Quieter rooms.

Modern triple-pane windows reduce exterior noise transmission noticeably, especially on a busy street or near schools. Most homeowners notice the change the first time a snowplow goes by at 6am and they do not wake up.

Even temperatures, floor to floor.

A properly sealed envelope reduces the temperature differential between rooms. The upstairs bedrooms stop being a different climate than the main floor.

Measurable energy savings.

Premium windows installed with proper substrate detailing reduce heat loss enough to register on the utility bill. The exact savings depend on the starting condition, but homeowners commonly see meaningful reductions in heating costs the first full winter.

A finished look that ties the home together.

Window upgrades change the elevation of the home, not just the rooms behind them. EnerClear coordinates frame colour, grille pattern, and trim detail with the rest of the exterior so the result reads as one intentional home.

05 · The full picture

Windows are where drafts live. They are rarely where drafts start.

Most window-only projects find that the actual air leakage was somewhere else: at the rim joist, behind the siding, around the soffit, or through compromised insulation. Replacing the window solves the symptom. Addressing the full envelope solves the cause.

When EnerClear approaches windows as part of a coordinated exterior project, we can air-seal and detail the rough opening with the same continuity used at the siding, trim, and insulation boundaries. The compounded effect is a tighter, quieter, more efficient home than any standalone window job can deliver.

06 · Common questions

What homeowners ask us about windows.

How do I know when my windows need replacing instead of repairing?

A few signals: condensation between the panes (failed seal), drafts you can feel from across the room, frames that do not operate smoothly, or windows older than 20 to 25 years. EnerClear assesses the full condition before recommending replacement. In some cases, targeted repair is the right call. In most cases, once one window is failing, the others are not far behind.

How long does a window replacement project take?

A whole-home window replacement on a single-family Calgary home typically runs three to seven days, depending on the number of openings and any substrate repairs needed. We give you a real schedule before work begins.

Why does EnerClear specify Lux?

After decades of installing windows in Calgary, Sean has settled on the manufacturer that consistently performs best in this climate. Lux delivers thermal performance, seal integrity, and long-term durability that consistently outperforms competing brands in Calgary's freeze-thaw, chinook, and UV conditions.

Can you replace windows in winter?

Yes, with the right protocols. EnerClear has installed windows in mid-winter Calgary conditions for years. The process changes (smaller openings open at a time, additional sealing, climate control inside), but the result is the same. A new opening means a day or two of minor disruption, and that short discomfort is far outweighed by decades of added comfort, lower bills, and quieter rooms once the new windows are in.

Do new windows pay back at resale?

Premium replacement windows are consistently among the highest-ROI exterior improvements in North America. Industry data places vinyl window replacements at roughly 67% cost recovery (NAR 2024 Remodeling Impact Report). The bigger return is comfort and efficiency every day you live in the home, plus stronger appraisal and listing performance when you sell.
