If you’re wondering, “Do exterior solar shades work?”, the short answer is yes. They’re among the most effective strategies for cooling your home, reducing glare, and protecting your patio and interior from UV damage.
Exterior installations, like exterior solar blinds, block sunlight before it even reaches your windows, making them significantly more efficient than indoor treatments.
How Effective is an Outdoor Solar Shade?
Exterior shutters and shades are the most effective at reducing solar heat gain, according to the U.S. Department of Energy. One study also shows that exterior shading can offer more than five times the solar protection compared to a white interior roller blind.
Performance of an Exterior Solar Blinds
Optimal performance depends on fabric weave tightness, commonly called openness percentage, and color.
Lower openness fabrics (1–5%) can block up to 95–99% of UV rays and provide more heat reduction and glare control. Medium openness (5–10%) balances visibility and protection—ideal for maintaining views while offering moderate heat and UV blockage.
UV Blocking Estimates
| Openness % | UV Blocking | Visibility |
|---|---|---|
| 1% | 99% | Very low visibility |
| 3% | ~97% | Minimal transparency |
| 5% | ~95% | Moderate view-through |
SelectBlinds offers openness percentages from 1% to 14% for exterior shades.
Benefits of an Exterior Solar Shade
Energy Efficiency & Comfort
Exterior shades intercept solar heat before it warms your patio or windows and interior air. Installing them can reduce indoor peak temperatures and lower cooling costs substantially — especially on west- and south-facing patios or windows.
UV & Glare Protection
By absorbing or reflecting sunlight before it passes through glass, exterior solar shades deliver real UV protection. This slows fading on patio furniture and prevents harsh glare during afternoon hours.
Visual Comfort with Ambient Views
Lower openness (tight weave) fabrics offer maximum heat and UV blocking, but limit outward visibility. Mid-range to high openness keeps views intact while still delivering meaningful sun control, making them ideal for for people who still want to enjoy their back or front yard.
Durability Tailored for Outdoors
Exterior solar treatments use weather-resistant hardware and UV‑stabilized fabrics, ensuring day-after-day performance in outdoor conditions. This makes exterior solar blinds a practical choice for patios and porches.
Are Exterior Solar Shades Worth It?
Absolutely — here’s why:
- If positioned in front of your home, they can eliminate solar heat before it enters your house, outperforming interior solutions in efficiency and comfort.
- With up to 99% UV blocking at low openness and lasting durability, they’re smart both cosmetically and practically.
- They increase backyard comfort, especially in summer months.
