LoE 272: Clear Views with All-Season Balance

LoE 272 is the balanced, all-season LoE. It keeps rooms bright, trims summer heat, and holds warmth in winter. In a dual-pane unit with argon fill, it delivers a noticeable comfort upgrade without the dim look of heavy tints—making it a great “default” choice for many orientations across the GTA.

At a glance: key performance (dual-pane argon)

Visible light

About 70% VT keeps interiors bright and natural.

Solar control

SHGC ≈ 0.41 limits summer heat while preserving daylight.

Insulation

U-factor ≈ 0.23 (center-of-glass) with argon helps hold heat on cold nights.

UV filtering

~84% of UV blocked (≈16% UV transmission) to help reduce fading.

Lower U-factor = better insulation; moderate SHGC = curbs summer overheating without making rooms feel dim.

Where LoE 272 fits best

Mixed orientations—fronts that see morning sun, sides with afternoon glare, and calmer north elevations. One coating that handles a bit of everything.

Main living areas—family rooms, kitchens, and offices where you want clear, neutral views and steady comfort year-round.

Renovations and glass-only replacements—a dependable “set-and-forget” spec when you want efficiency gains without a dramatic change in look.

How it balances light & heat

LoE 272 uses a dual-silver, microscopically thin metallic layer on the second surface of a sealed unit. That stack lets generous daylight through, reflects a portion of the sun’s infrared heat in summer, and bounces room heat back inside in winter. Add argon gas between the panes and the insulating boost is even stronger.

Good to know

Placement

Typically applied on the #2 surface for dual-pane builds, balancing clarity with solar control.

Neutral look

Clear, true-to-life views without a bronze or grey cast—a clean match for modern interiors.

Safety options

Available tempered or laminated for doors, bathrooms, and other safety-rated locations.

Standards

Engineered and rated under NFRC / ENERGY STAR test conditions for reliable comparisons.

LoE-272 vs other LoE choices

Helpful pairings & upgrades

Argon fill

The inert gas between panes slows heat flow and improves both winter and summer comfort.

Warm-edge spacers

Modern spacer tech reduces edge heat loss and helps limit condensation at the perimeter.

When to choose something else

If a room already overheats in summer or faces intense afternoon sun, step up to LoE-366. If you’re focused on maximizing winter sun on south glass, LoE-180 may be the better match.
