Glass vs Aluminum Patio Covers: Complete Comparison Guide
Two premium patio cover options. Completely different experiences. Glass keeps you connected to the sky while aluminum wraps you in shade. Both handle Okanagan weather. Both last decades. The right choice depends on your patio’s orientation, your budget, and whether you’d rather see your view or escape the sun.

Glass Patio Covers Explained
What is a Glass Patio Cover?
A glass patio cover uses tempered safety glass panels supported by an aluminum frame. Think of it as a skylight for your outdoor space—full weather protection without losing the view overhead.
Most installations use 6mm tempered glass for standard spans or 10mm laminated glass for larger areas. The glass can be clear, tinted (bronze or grey), or frosted for privacy. Some homeowners opt for self-cleaning coatings that add $1,500-$3,000 but cut cleaning time in half.
Types of Glass Used
| Glass Type | Light Transmission | UV Block | Best For |
|---|---|---|---|
| Clear tempered | 90-100% | Low | Maximum brightness |
| Tinted (bronze/grey) | 50-70% | Medium | Glare reduction |
| Low-E coated | 70-80% | High | Heat control |
| Frosted/sandblasted | 40-60% | Medium | Privacy |
Pros of Glass Patio Covers
- Preserves views: See the sky, mountains, and Okanagan Lake from underneath
- Natural light: Bright space without feeling closed in
- All-weather protection: Rain, wind, snow—while watching it happen above you
- Modern aesthetic: Clean, contemporary architectural look
- Year-round use: Natural light reaches your patio even in short winter days
Cons of Glass Patio Covers
- Higher cost: Typically 80-100% more than aluminum
- Cleaning required: Bird droppings, leaves, and water spots are visible
- Heat gain: Can be hot underneath on summer afternoons (unless you go with tinted glass)
- Glare: Sunlight reflection can be intense at certain times of day
- Heavier: May require more robust support structure
Okanagan-Specific Considerations for Glass
Living in the Okanagan changes the glass equation. Here’s what we’ve learned from hundreds of local installations:
- Lake effect humidity: Freshwater means no salt spray corrosion—a non-issue here unlike coastal BC
- Summer heat: For south or west-facing patios, tinted glass is almost mandatory unless you want a greenhouse effect
- Snow visibility: You’ll see snow pile up on top—some people love the view, others find it unsettling
- Winter light: Glass captures those low winter sun angles better than solid covers, keeping your patio usable into November
- View priority: Lake and mountain views are what people move here for. Glass lets you keep them overhead
Aluminum Patio Covers Explained
What is an Aluminum Patio Cover?
An aluminum patio cover uses solid extruded aluminum panels—typically 6061-T6 alloy, the same marine-grade aluminum used in boat hulls. It’s powder-coated for color and corrosion resistance, and comes in flat roof, gabled, insulated, or louvered configurations.
This is the most popular choice in the Okanagan, and for good reason: solid shade, strong structure, zero maintenance, and significantly lower cost than glass.
Types of Aluminum Covers
| Type | Light | Features | Cost Range |
|---|---|---|---|
| Flat solid | 0% | Simple, clean lines | $ |
| Gabled | 0% | Pitched roof for snow/rain runoff | $$ |
| Insulated | 0% | Foam core reduces heat transfer | $$$ |
| Louvered | Adjustable 0-100% | Opens and closes for light control | $$$$ |
Pros of Aluminum Patio Covers
- Full shade: Complete sun protection—no squinting, no sunscreen
- Lower cost: Typically 40-50% less than glass for the same coverage area
- Zero maintenance: Rain keeps it clean, powder coat lasts decades
- Durable: 25-30 year lifespan with minimal attention
- Versatile: Multiple colors, styles, and attachment options available
- Cooler underneath: Significantly reduces patio temperature on hot days
Cons of Aluminum Patio Covers
- Blocks light: Your covered space will feel darker
- Blocks views: Can’t see sky, trees, or stars above
- Can feel enclosed: Less open and airy aesthetic than glass
- Rain noise: More audible than glass (insulated panels help)
Okanagan-Specific Considerations for Aluminum
- Hot summers: Shade is a major benefit when you’re seeing 30-35°C regularly from June through August
- Snow loads: All our aluminum covers are engineered for 40 PSF minimum (BC Building Code requirement for Kelowna)
- UV protection: 100% UV block is important for outdoor furniture—cushions and wood finishes last longer
- Low maintenance: Powder coat handles valley dust and occasional wildfire smoke without corrosion
- Budget-friendly: You can cover more square footage for the same investment

Snow Load & Weather Performance
Snow Load Ratings
This matters in the Okanagan. The BC Building Code requires structures in Kelowna to handle a minimum snow load of 40 PSF (pounds per square foot). Higher elevations like Big White or SilverStar require custom engineering.
- Glass covers: Engineered for 40+ PSF with proper frame design and 6mm+ tempered glass
- Aluminum covers: Standard designs meet 40+ PSF—the material is inherently strong and lightweight
- Higher elevations: We engineer for specific locations when needed
Other Weather Considerations
| Weather | Glass | Aluminum |
|---|---|---|
| Rain | Full protection, quiet | Full protection, more audible |
| Wind | Solid, may whistle at gaps | Solid |
| Hail | Tempered glass resists damage | Minimal impact on aluminum |
| UV | Transmits UV (unless coated) | Blocks 100% |
Best Use Cases
Choose Glass If:
- View is priority: Lakefront property, mountain views, mature trees you want to see
- Light matters: North-facing patio, shaded yard, or you just hate dark spaces
- Aesthetic preference: Modern, open, architectural look is what you’re after
- Winter use: Want natural light during our short winter days
- Budget allows: Willing to pay the premium for the experience
Choose Aluminum If:

Which is better for hot Okanagan summers, glass or aluminum?
Aluminum provides full shade and keeps areas significantly cooler. Glass transmits heat unless you use tinted or Low-E coated panels. For south or west-facing patios in Kelowna, aluminum or tinted glass is recommended. Clear glass on a south-facing patio can feel like a greenhouse by mid-afternoon in July.
Can glass patio covers handle Okanagan snow loads?
Yes. Properly engineered glass covers use 6mm+ tempered glass and reinforced frames rated for 40+ PSF (BC Building Code requirement for Kelowna). Every glass cover we install includes engineering certification for local snow load requirements. Higher elevation areas may require additional engineering.
Do glass patio covers break easily?
No. Tempered safety glass is 4-5 times stronger than regular glass. If it does break (extremely rare—we’ve never had a failure), it shatters into small, harmless pieces rather than dangerous shards. This is the same glass used in car windows and shower doors.
How often do glass patio covers need cleaning?
Most homeowners clean 2-4 times per year. If you’re near deciduous trees, you may want to clean more often in fall. Self-cleaning coatings (hydrophilic technology) reduce cleaning frequency by 50-70% but add $1,500-$3,000 to the project cost.
Can I add a fan or lights to an aluminum patio cover?
Yes, and this is one of aluminum’s advantages. The solid roof easily accommodates ceiling fans, recessed lighting, patio heaters, and speakers. We can pre-wire during installation or you can add electrical later—the structure supports it either way.
Which adds more home value, glass or aluminum?
Both add value to your home. Glass covers may have a slight edge on premium lakefront properties where preserving views matters to buyers. Aluminum is a better value proposition overall—lower cost with a solid return on investment. Either option is significantly better than no cover at all.
What’s better for a hot tub area?
Aluminum is typically the preferred choice. It provides full shade (keeping spa temperatures comfortable), offers privacy, and requires no maintenance despite constant steam exposure. The last thing you want is to be looking up at water spots and debris while you’re trying to relax.
