Outdoor curtains can make a patio, porch, or gazebo feel more comfortable by blocking some wind and sunlight. If your goal is to keep heat in, look for thick, closely woven fabric and a way to secure the panels so they do not billow. Keep expectations realistic: curtains can help reduce drafts around a partly enclosed space, but they are not a replacement for insulated walls or windows.
Our picks include options with thermal-insulation claims, wind-stabilizing features, and simple weather-resistant designs. Before you buy, check whether the listing includes one panel or a pair, then measure your opening and curtain rod.

Our Picks: Best Outdoor Curtains To Keep Heat In reviews
NICETOWN Biscotti Beige: A Longer Single Panel With Thermal Features
This NICETOWN curtain is sold as one panel and measures 95 inches long. Its triple-weave fabric is designed to block sunlight, and the product description also highlights thermal insulation. That combination may be useful if you want to limit sun exposure in warm weather and help a sheltered outdoor area feel less exposed when temperatures drop.
The fabric is described as waterproof, with the same color and material on both sides. A 1.6-inch stainless-steel grommet top fits compatible curtain rods. Since the listing includes one panel and does not give its width in the supplied details, confirm that the panel count and coverage suit your opening before ordering.
This is a practical choice when you need one long panel rather than a full pair. It may also work as a divider or for indoor use, but its thermal benefits outdoors will depend on how enclosed the space is and how well the curtain can be closed around gaps.
Pros:
- 95-inch length for taller openings
- Triple-weave fabric with thermal-insulation and sunlight-blocking claims
- Waterproof construction and matching fabric on both sides
- Machine washable, with low-temperature ironing recommended
Cons:
- Only one panel is included
- The supplied product details do not specify the panel width
Verdict: Choose this NICETOWN panel if you need a longer, single curtain with both weather protection and thermal features, and have checked that one panel will cover your space.
DIVA EN CAMINO DEC: A Two-Panel Set for Wider Openings
This set includes two panels, each 52 inches wide and 84 inches long. The triple-weave polyester fabric has a waterproof coating on both sides, and the 1.6-inch rust-resistant grommets are designed to fit many standard curtain rods. Together, the pair offers more coverage than a single-panel option, though the right fit still depends on the width of your opening and how much fullness you want.
The listing describes the fabric as thick and suitable for blocking sunlight and providing privacy. It also notes that darker colors generally block more light than lighter ones. That can matter if you want shade during the day, but blocking sunlight is not the same as trapping heat. For warmth, consider how well the curtains can close off breezes around the sides and bottom.
Length options are listed from 63 to 132 inches, so you can compare sizes for your setup. The main trade-off is that the supplied details do not mention a system for anchoring the bottoms in wind. In a breezy location, you may need another way to keep the panels from moving.
Pros:
- Two panels provide coverage for a broader opening
- Waterproof coating on both sides of the fabric
- Multiple length options are listed
- Grommet top makes the panels straightforward to hang on a compatible rod
Cons:
- No bottom anchoring system is specified in the supplied details
- Light blocking varies by color, so lighter shades may let in more light
Verdict: This set is a sensible option if you want two waterproof panels for a wider opening and do not need built-in wind anchors.
NICETOWN Windproof Thermal Curtains: Best for a Breezy Setup
This two-panel NICETOWN set is designed with wind exposure in mind. Each 52-by-84-inch panel uses 220gsm fabric with a waterproof pretreatment. The top has rustproof grommets, while the bottom offers grommets, rod pockets, or back tabs for hanging and anchoring. An included rope can help secure the panels and reduce flapping.
The triple-weave fabric is described as a thermal barrier that can reduce heat transfer. The product also claims UPF 50+ protection and says shaded areas may be cooler than direct sun. Those are manufacturer claims, not a guarantee of a specific temperature or warmth level in your own space. In practice, the ability to reduce drafts will depend on your setup and how securely you can close the curtain edges.
Compared with the other picks, this set has the most detailed wind-stabilizing design. The trade-off is that using its different hanging options may take more setup than a basic grommet-only curtain. It is a strong fit for a gazebo or patio where wind movement is a concern.
Pros:
- Two panels with multiple hanging and bottom-anchoring options
- Includes rope for added stability
- Thick fabric with waterproof pretreatment
- Thermal and UV-protection features are specified by the manufacturer
Cons:
- Anchoring and hanging options may take more setup than a basic panel
- Thermal and temperature claims will vary with the space and installation
Verdict: Pick this set if your main concerns are wind movement, weather exposure, and a more secure fit, while treating its thermal claims as helpful features rather than guaranteed results.
BONZER Waterproof Curtain: A Simple, Opaque Single Panel
The BONZER is a single 54-by-84-inch panel made from thick polyester. It has rustproof 1.6-inch grommets and is described as waterproof and opaque. That makes it useful when you want to screen one side of a porch or balcony from rain and outside views without buying a pair of panels.
The product description says the curtain can block some sunlight, but it does not make a specific thermal-insulation claim. Its thickness and privacy-focused design may help create a more sheltered feel, but shoppers focused on keeping warmth in may prefer one of the options with more explicit thermal features.
The fabric is the same color on both sides, and the listing suggests weight bags for added security in wind; those bags are not included. This makes it less ready for a gusty space than the NICETOWN windproof set, but its straightforward one-panel format may be a better match for a smaller opening.
Pros:
- One 54-by-84-inch panel for a single opening
- Thick, opaque fabric for privacy
- Waterproof polyester with rustproof grommets
- Machine washable on a gentle, cold-water cycle
Cons:
- Only one panel is included
- Weight bags for added wind stability are not included
Verdict: Choose BONZER for a simple, private, waterproof single panel; consider a more explicitly thermal option if heat retention is your top priority.
Easy-Going Waterproof Curtains: A Two-Panel Set for Weather Protection
This Easy-Going set includes two panels, each 54 inches wide and 84 inches long. The fabric is described as 100% waterproof, UV-resistant, and suitable for outdoor spaces such as patios, porches, and gazebos. Silver rustproof grommets with a 1.6-inch inner diameter are designed to work with compatible rods.
The product description emphasizes weather protection, fade resistance, and privacy. It does not specify a thermal barrier or heat-retention performance, so this set is best viewed as a weatherproof screen rather than a dedicated insulating curtain. Blocking rain and some exposure may still help make a sheltered area more usable, but it will not seal a space by itself.
Compared with BONZER, this option includes a pair of wider panels, making it more suited to covering a larger span. The supplied details do not describe a bottom tie-down system, so it may move in strong wind. The fabric can be cleaned with a wet cloth or water and is also machine washable in cold water.
Pros:
- Two 54-inch-wide panels are included
- Waterproof and UV-resistant fabric
- Rustproof grommets for hanging on a compatible rod
- Can be cleaned with a wet cloth, water, or a cold machine wash
Cons:
- No specific thermal-insulation claim is provided
- No bottom anchoring system is described
Verdict: Choose Easy-Going if you need a two-panel weather-resistant set, but look to a thermal-focused or anchor-equipped option for stronger heat-retention or wind-control features.
How to Choose Outdoor Curtains to Help Keep Heat In
Look for a Dense, Layered Fabric
Thicker, closely woven fabric is generally a better starting point for limiting airflow and creating a more sheltered space. Some of these curtains describe triple-weave construction or thermal insulation, while others focus mainly on waterproofing and privacy. Compare the product’s stated features rather than assuming every outdoor curtain offers the same warmth.
Think About How Enclosed Your Space Is
A curtain can only do so much if wind can move freely around the sides, top, or bottom. Curtains are most useful for softening drafts in a partly enclosed porch, gazebo, or patio. They will not provide the same heat retention as insulated walls, windows, or doors, and their performance can vary with the layout and weather.
Measure the Opening and Check the Panel Count
Measure the width and height of the space before ordering. Check whether the package includes one panel or two, and note the width and length of each panel. A single panel may be enough to cover one side, while a pair can span a wider opening. Allow for the amount of fullness you want instead of matching the curtain width exactly to the opening.
Choose a Secure Hanging Method for Wind
Grommets make curtains easy to slide onto a compatible rod, but they do not stop the bottom edge from moving. If your patio is exposed to wind, look for bottom tabs, extra grommets, rod pockets, or included ties and rope. The NICETOWN windproof set offers several bottom attachment options; other picks do not specify a built-in anchoring method.
Balance Light Blocking With Color
Outdoor curtains can reduce sunlight and help shade furniture, but the amount of light blocked may depend on fabric and color. One listing specifically notes that darker shades generally block more light than lighter shades. If your main goal is keeping a space warm, focus on fabric construction and limiting drafts as well as color.
Check Weather Claims and Care Instructions
Waterproof, water-resistant, and weatherproof are not interchangeable guarantees of performance in every storm. Review the product’s own description and consider how exposed the curtain will be. Also check care directions: the products here range from cold machine washing to gentle-cycle washing, and some recommend low-temperature ironing or drying.
Frequently Asked Questions
Can outdoor curtains really keep heat in?
They may help reduce drafts and make a partly enclosed area feel more sheltered, especially if the fabric is dense and the edges can be secured. They are not a substitute for insulation, and their effect depends on the space and conditions.
Which option has the clearest thermal features?
The two NICETOWN options specifically describe thermal insulation or a thermal barrier. The windproof set also has multiple anchoring options, while the longer Biscotti Beige panel is sold individually.
Are these curtains sold as single panels or pairs?
Both formats are represented. The Biscotti Beige NICETOWN curtain and BONZER curtain are each sold as one panel. The DIVA EN CAMINO DEC, NICETOWN windproof, and Easy-Going products include two panels. Check the listing details before ordering.
Do waterproof curtains block all sunlight?
Not necessarily. Waterproofing describes protection from water, not a specific level of light blocking. Some listings describe sunlight reduction, and one notes that darker colors generally block more light than lighter colors.
How can I stop outdoor curtains from blowing around?
Use a suitable rod and look for curtains with bottom tabs, grommets, or other attachment points. The NICETOWN windproof set includes rope and several hanging options. For other models, the supplied details do not specify built-in bottom anchors.
What should I measure before buying?
Measure the width and height of the opening, then compare those dimensions with each panel’s listed size. Confirm the number of panels in the package, the curtain length, and whether the grommet size is compatible with your rod.
Can outdoor curtains stay outside all year?
The products are described for outdoor use, and several have waterproof or weather-resistant features. Still, the supplied information does not guarantee performance in every climate or storm. Follow the care instructions and consider taking curtains down when conditions could damage them.
Final Recommendation
For the best balance of thermal features and wind control, the NICETOWN windproof set is the strongest match in this group because it combines a thermal-barrier claim with several ways to secure the panels. If you want a single longer curtain, consider the NICETOWN Biscotti Beige option. For a wider opening where weather protection matters more than explicit insulation, the DIVA EN CAMINO DEC or Easy-Going two-panel set may be a better fit. Measure carefully, secure the edges where possible, and remember that outdoor curtains can reduce drafts but cannot replace proper insulation.
