For homeowners who want UV protection without losing daylight or their view, low-openness solar shades are the right choice. The single spec that matters most is openness factor: solar shade fabrics can block nearly all UV rays at very low openness, while fabrics with moderate openness still block a significant portion of UV. Color, price, and brand matter far less than that one number.
Here is the quick decision guide:
- Low openness fabrics offer maximum UV and glare protection, ideal for windows with intense sun exposure and valuable interiors.
- Moderate openness fabrics balance UV blocking and outward view, suitable for main living spaces.
- Higher openness fabrics prioritize view, allowing more light and some UV through.
To find the right openness for each window in your home, order free swatches and schedule a free in-home consultation with Made in the Shade Bucks County. A consultant brings samples directly to your home and measures on-site so you see exactly how each fabric performs in your actual light before ordering.

How do UV blocking window shades actually work?
Solar shades are roller shades made from technical screen fabrics with an open-weave structure often treated to intercept and reflect UV radiation before it reaches furniture, floors, and artwork.
The key distinction from standard roller or blackout shades is the purpose. Blackout shades block all light; solar shades are engineered to filter UV and reduce glare while keeping your connection to the outdoors. You can still see through them during the day, and natural light still fills the room.
Standard residential glass blocks most UVB rays but allows UVA rays to pass through, which can cause fading of fabrics, bleaching of wood finishes, and degradation of leather over time. Solar shades filter these invisible rays the way sunglasses protect your eyes, intercepting what your glass misses.
Pro Tip: Before ordering, request free fabric swatches from Made in the Shade Bucks County and hold them against your actual windows in the afternoon sun. The difference between a 3% and a 10% openness fabric is immediately visible in real daylight, and you will not regret taking that extra step.
What does openness factor mean for UV blocking and glare?
Openness factor is the primary specification manufacturers use to describe how tightly a solar shade fabric is woven. A lower percentage means a tighter weave, stronger UV and glare control, and a slightly darker interior. A higher percentage means a more open weave, better outward visibility, and less UV protection.
The numbers break down like this:
- Very low openness fabrics block nearly all UV rays, with minimal outward view, ideal for rooms with intense sun or valuable contents.
- Moderate openness fabrics offer a good balance of UV protection and visibility, popular for various living spaces.
- Higher openness fabrics block a meaningful portion of UV but allow more glare and heat.
Practical room-by-room guidance from solar shade fabric research:
- South- and west-facing windows usually need fabrics with tighter weaves due to intense direct sun.
- Media rooms and home offices benefit from tighter weave fabrics to reduce glare and protect screens.
- Living rooms with views can use moderate openness fabrics to preserve outlook while reducing UV.
- Rooms prioritizing daylight may use higher openness fabrics that reduce some UV but allow more light.
One thing worth knowing: dark fabric colors improve outward view clarity and reduce glare, but color does not equal UV protection. A light-colored 1% fabric blocks just as much UV as a dark one at the same openness. Choose color for aesthetics and glare preference; choose openness for UV performance.
What do UV protection solar shades actually protect in your home?
The benefits go well beyond a cooler room. Here is what solar shades concretely protect and improve:
- Furniture and upholstery: UV fading is cumulative. Sofas, rugs, and curtains near south- or west-facing windows can show visible color loss within a few years of unprotected sun exposure.
- Hardwood floors: Sun exposure is one of the leading causes of floor discoloration. Pairing solar shades with the right flooring material choices by room gives you a complete protection strategy.
- Artwork and collectibles: UV is the primary cause of pigment degradation in paintings, prints, and photographs. Low-openness solar shades are a practical first line of defense.
- Glare reduction: Solar shades make screens usable in rooms that would otherwise require blackout treatments during the day.
- Energy savings: Adding solar shades can cut window-related heat transfer by roughly 30% and may lower summertime cooling costs by an estimated 15%–25%. That is a meaningful reduction for a Bucks County home running central air through July and August.
Solar shades do have limits. They reduce UV and heat transfer significantly, but they are not a substitute for blackout shades when you need full darkness. They also do not provide full nighttime privacy when interior lights are on, because the view-through effect reverses after dark. Layering with drapery or a secondary blind solves that, which is covered in the alternatives section below.
For energy efficient window coverings that do double duty on UV protection and cooling costs, solar shades are the most practical single-product solution available.
How do you choose the right shade for each window?
The right solar shade depends on the window’s orientation, what is near it, and how you use the room. Working through a short checklist before ordering saves you from choosing a fabric that looks great in a showroom but underperforms at home.
- Identify sun direction and intensity. South- and west-facing windows get the most UV load. Note which rooms feel hottest in the afternoon.
- Assess what needs protecting. Hardwood floors, upholstered furniture, artwork, and rugs near windows are the highest-priority targets. The more valuable the contents, the lower the openness you want.
- Decide on view vs. privacy. A 1% shade gives strong UV protection but a more filtered view. If the window overlooks a garden you love, 3%–5% may be the better trade-off.
- Consider screen use. Home offices and media rooms benefit from tighter openness to eliminate glare on monitors and TVs.
- Think about layering. If you need nighttime privacy or occasional full darkness, plan for a secondary treatment from the start rather than retrofitting later.
When talking to a vendor or consultant, ask these questions directly:
- What openness percentages do you carry, and can I see swatches in my home?
- What is the manufacturer warranty on the fabric and hardware?
- Is motorization available, and does it integrate with Alexa or other smart-home platforms?
- Do you offer professional measurement and installation?
Pro Tip: Watch for vendors who quote openness in vague terms like “light filtering” without giving you a specific percentage. A reputable supplier will hand you a spec sheet or a swatch card with the openness number printed on it. If they cannot, keep looking.
Why professional measurement matters more than most homeowners expect
A solar shade that is measured incorrectly loses much of its UV-blocking value before it is even installed. The “light gap,” the space between the fabric edge and the window frame, is where UV and glare leak through. Custom-measured solutions with slim headrails and side channels minimize that gap and protect interiors far more effectively than a shade that is close but not precise.
For standard, square windows in newer construction, careful DIY measurement is possible. But older homes in Bucks County and Mercer County often have windows that are not perfectly square, frames that have settled, or trim profiles that complicate a clean inside-mount fit. A professional measurement catches those issues before the fabric is cut.
The typical timeline for a custom solar shade project runs from initial measurement through delivery and installation. Made in the Shade Bucks County handles measurement and installation as part of the service, and products carry manufacturer warranties, most with limited lifetime coverage, that protect your investment after the install.
Motorization, smart-home controls, and child-safe lift options
Motorized solar shades are worth considering for any window that is large, hard to reach, or part of a room where you want consistent, repeatable light control. The practical benefits are real: you can lower every south-facing shade at noon with a single command and raise them again at sunset without touching a cord.
Control options available through Made in the Shade Bucks County’s window motorization offerings include:
- Remote controls: Handheld remotes for individual shades or grouped zones.
- Wall switches: In-wall controls that replace the look of a standard light switch.
- Smart-home integration: Hub-connected systems compatible with Alexa and other major platforms, allowing voice commands and automation scenes.
For homes with children, cordless lifts remove the loop hazard entirely. The Consumer Product Safety Commission has long identified corded window coverings as a strangulation risk for young children. Cordless and motorized options eliminate that risk while also giving a cleaner visual appearance. Child-safe lift options are available across the solar shade range.
Motorization is particularly practical for large windows, skylights, and any opening where manual operation is awkward. It also makes UV protection more consistent: when raising and lowering shades is effortless, homeowners actually use them at the right times of day rather than leaving them up through peak sun hours.
How do solar shades compare to window film, blackout shades, and exterior awnings?
Each UV-control option has a different role. Solar shades are the most flexible, but they are not always the only answer.
| Option | UV Block | Adjustability | View | Best Use |
|---|---|---|---|---|
| Solar shades (1%) | Up to 99% | Fully adjustable | Maintained during day | Primary UV/glare control, most rooms |
| Solar shades (3%) | ~97% | Fully adjustable | Maintained during day | Balance between UV protection and view |
| Window film | Up to 99% (continuous) | Permanent | Maintained | Always-on protection for high-value interiors |
| Blackout shades | — | Fully adjustable | None when closed | Bedrooms, media rooms needing full darkness |
| Exterior awnings/screens | Very high (blocks before glass) | Seasonal/retractable | Reduced | South/west patios, large glazing |
Layering window film with solar shades gives the strongest continuous UV protection: film handles the UV load when the shades are raised, and the shades add glare control and adjustability when lowered. This combination makes the most sense for rooms with irreplaceable art, antique furniture, or flooring that cannot be replaced easily.
Exterior screens block sunlight before it reaches the glass, which is the most effective approach for heat reduction on south- and west-facing exposures. Made in the Shade Bucks County offers outdoor patio shades for exactly these situations, and they pair well with interior solar shades for a layered system.
Window film is permanent and nearly invisible, which makes it a strong choice when you want always-on protection without changing the look of a room. The trade-off is that it cannot be adjusted for privacy or darkness. Solar shades give you that flexibility. For most homeowners, the practical answer is to use layered window treatments rather than treating it as an either/or decision.
How to care for solar shades and what to look for in a warranty
Solar shade fabrics are durable, but they do require basic maintenance to keep performing well over time.
- Dust regularly: Use a soft brush attachment on a vacuum or a dry microfiber cloth. Dust buildup on the fabric surface reduces light transmission and can trap moisture.
- Spot clean carefully: Use a mild soap solution and a soft cloth for small stains. Avoid soaking the fabric or using abrasive cleaners, which can damage the weave and any UV-blocking coating.
- Inspect annually: Each spring, raise the shade fully and examine the fabric for signs of wear, discoloration, or thinning at the edges. UV exposure degrades even high-quality fabrics over many years of intense sun.
- Check hardware: Inspect the headrail, brackets, and any motorized components for smooth operation. Catching a small mechanical issue early prevents a larger repair later.
Before purchasing, confirm two things with your supplier: the specific warranty terms (most quality manufacturers offer limited lifetime coverage on fabric and hardware) and whether free swatches are available. Seeing a fabric sample in your actual window under real daylight is the only reliable way to evaluate how it will perform, and any reputable supplier should offer that at no cost.
Key Takeaways
Solar shades with a 1% openness factor provide the maximum UV blocking for most homes, blocking up to 99% of UV rays while preserving natural light and outward views. Fabrics with 3% openness still offer strong performance, blocking roughly 97% of UV, balancing protection with a preserved view.
| Point | Details |
|---|---|
| Openness factor is the key spec | Choose 1% for maximum UV block (~99%); 3% for strong UV protection (~97%); 5%–10% when view and daylight are the priority. |
| Color does not equal protection | UV blocking comes from the weave and openness, not the fabric color. |
| Light gaps reduce effectiveness | Professional measurement and slim headrails close the gap where UV leaks around the shade. |
| Layering adds full-day protection | Combining solar shades with window film or drapery covers UV when shades are raised and adds nighttime privacy. |

The case for getting this right the first time
There is a version of this purchase that goes wrong in a predictable way. A homeowner picks a solar shade based on color and price, installs it without precise measurement, and ends up with a fabric that looks fine but has a 10% openness and a half-inch light gap on each side. The UV protection delivered is a fraction of what the spec sheet promised.
The openness factor guidance in this article is not complicated, but it does require knowing your windows: their orientation, the gap between frame and fabric, and what you are actually trying to protect. A south-facing living room in a 1970s colonial in Doylestown has different needs than a modern addition with floor-to-ceiling glass in Princeton. Getting the right answer means looking at the actual window, not just a product page.
That is the practical argument for a measured, in-home approach. Seeing swatches in your own light, with a consultant who can confirm the openness spec and the fit, removes the guesswork that leads to underperforming shades. Motorization and child-safe options are worth discussing at the same time, because retrofitting them later costs more and sometimes is not possible with the hardware already installed.
The fabric, the fit, and the controls all matter. Getting all three right on the first order is the goal.

FAQ
Do window shades block UV rays?
Yes. Solar shades are specifically designed to filter UV rays, with low-openness fabrics (1%–3%) blocking up to 99% of UV. Standard roller or blackout shades block light but are not engineered for UV filtering the way solar shade fabrics are.
What is the best window covering to block the sun?
Low-openness solar shades (1%) are the most practical choice for maximum UV protection in most rooms, blocking up to 99% of UV. 3% openness shades offer strong protection (about 97% UV block) with preserved daylight and view. For maximum protection in high-value spaces, layering solar shades with window film provides near-continuous UV blocking even when the shades are raised.
Does UV blocking window film actually work?
Window film can block up to 99% of UV rays continuously, making it one of the most effective single interventions for fading protection. Its limitation is that it is permanent and cannot be adjusted for privacy or darkness, which is why many homeowners pair it with adjustable solar shades.
What openness percentage is best for UV protection?
A 1% openness fabric delivers the highest UV protection, blocking approximately 99% of UV rays. For most living spaces where some outward view matters, 3%–5% openness offers a strong balance, blocking roughly 95%–97% of UV while keeping the room bright.
Can Made in the Shade Bucks County help me choose the right solar shade?
Yes. Made in the Shade Bucks County offers a free in-home consultation where a consultant brings fabric swatches to your home, evaluates each window’s orientation and light conditions, and recommends the right openness and fabric for each room, with professional measurement and installation included.
