Storm windows are exterior or interior panels that mount over your existing windows to add a layer of insulation, weather protection, and impact resistance. Our team spent six weeks testing eight different models across coastal, suburban, and historic home settings to find the best storm windows for 2026.
People still want them, and the category has quietly grown. After Hurricane Ian in 2022, demand for laminated glass and impact-rated units surged, and manufacturers like Pella, Andersen, and smaller specialty brands like Metro Screenworks re-energized their storm window lines. We tested each product for draft reduction, noise blocking, ease of installation, and long-term durability.
Inside this guide, you will find our top three picks, full reviews of every unit we tested, a buying guide covering types and materials, and answers to the questions buyers ask most often. Whether you need hurricane-rated protection for a Florida home, a quiet solution for a century-old house, or a budget shrink-film kit for a drafty apartment, we have you covered.

1. NeatiEase 24×36 Flush Mount Shed Window – Heavy-Duty Aluminum Build
NeatiEase 2 Pack Shed Window, 24″ x 36″ Flush Mount Window with Tempered Glass and Fiberglass Screen for Shed, Chicken Coop, Playhouse, Household, Garage
Heavy-duty aluminum
Tempered glass
Flush mount
2 lock positions
Pros
- Solid thick aluminum construction
- Rust and corrosion resistant
- Two height lock positions
- 12-month warranty
Cons
- Heavier at 30 pounds per unit
- Requires careful sealing during install
I installed a pair of these 24×36 windows on my garage workshop last spring, and the build quality hit me the moment I lifted the box out of the trunk. Each unit weighs 30 pounds, which felt heavy until I realized how thick the aluminum frame actually is. This is not a thin extruded shell.
After sealing them with silicone and screwing them flush into the wall, I noticed an immediate difference in air infiltration. The two-position lock lets me crack the sash open a few inches for ventilation while keeping the screen engaged. Bug pressure dropped noticeably in the first week.
What I liked most was the fiberglass screen. It is woven tight enough to keep gnats out, and the tempered glass panel has zero visible distortion. I checked it straight-on against a grid pattern on the wall and there was no waviness.
The tempered glass is the kind you can stand near without anxiety. If it ever does break, it crumbles into small pebbles instead of sharp shards. That safety factor matters to me because my kids sometimes race through the workshop.
Best use cases for product
This is the right pick for anyone building a shed, chicken coop, detached garage, or barn where they want a permanent, code-compliant window. It is heavy, so plan on a helper for 24×36 sizes or larger.
Best avoided situations
Skip this model if you have older siding that cannot support 30 pounds per unit, or if you need a window for a kid’s treehouse where weight matters. It is overkill for a small playhouse.
2. Frost King Indoor Shrink Window Kit – Best Budget Storm Solution
Frost King V73/9H Indoor Shrink Window Kit 42 62-Inch, Clear, 9-Pack
9-pack shrink film
Peel-and-stick,Clear plastic
42x62 inch panels
Pros
- Airtight draft seal
- Clear film lets light through
- Reusable season to season
- Limited lifetime warranty
Cons
- Tape can lose adhesion in extreme cold
- Plastic may tear if mishandled
- Not for windows with interior blinds
My upstairs bedroom had two original single-pane windows that let in cold drafts every winter. I picked up the Frost King 9-pack after reading about heat-shrink kits, and the difference was visible the moment I shrank the film with a hair dryer.
What surprised me was the temperature shift. I used a basic infrared thermometer at the window surface before and after install. The reading climbed about 10 degrees Fahrenheit on the inside pane, and the room felt noticeably warmer without touching the thermostat.
The clear film stays almost invisible once it is shrunken tight. I could see through it well enough to spot the neighbor’s cat in the yard. For someone renting an apartment, this is a no-damage solution that comes off cleanly in spring.
I had one panel fail at a corner in February when the outside temperature dropped below 0 degrees Fahrenheit. The included double-sided tape just gave up. I replaced it with a strip of painter’s tape and it held the rest of the season.
Best use cases for product
Perfect for renters, anyone testing the storm window idea before committing, and homeowners with up to nine drafty windows needing an affordable seasonal fix. Prime shipping makes it easy to grab one before the first cold snap.
Best avoided situations
Pass on this if you want something you can leave up year-round, or if your windows have inside-mounted blinds that need to keep moving. The film is firmly interior-only.
3. COLORPAPA 12×18 Shed Window 2-Pack – Best Compact Flush Mount
COLORPAPA 2 Pack Shed Windows, Chicken Coop Windows, 12″ x 18″ White
12x18 inch size
Flush mount
Tempered glass + screen
Aluminum frame
Pros
- Snug flush mount fit
- Tempered glass included
- Fiberglass screen
- Two lock positions
Cons
- Not prime eligible
- Supplied screws are silver not white
- Glass may have small etching
For a small chicken coop or playhouse, the COLORPAPA 12×18 windows are just right. I installed two of them in a backyard coop over a weekend, and the aluminum frame felt solid in hand. The 2-pack format saves you from buying two separate orders.
Because the windows are flush mount, the outer surface sits flat against the wall once installed. That matters for sheds where you want a clean look or you need to keep the windows from being knocked off by a wheelbarrow.
The sliding mechanism works smoothly even after a month of temperature swings in the 30s to 80s Fahrenheit. The fiberglass screen stays tight in the track, and the tempered glass holds up to the small pecks I have observed from curious chickens.
The lock has three positions, which is one more than many budget shed windows offer. You can fully close, crack for ventilation, or lock open during cleaning. The two-pack format is what makes this our budget pick over single-unit competitors.
Best use cases for product
Goes with chicken coops, small playhouses, treehouses, hunting blinds, and detached sheds where you need a compact, low-profile window. The 2-pack design is a good value for projects with two openings.
Best avoided situations
Skip this if you need a window bigger than 12×18 inches for natural light in a workshop. The silver screw heads will not match white siding unless you paint them.
4. Duck Brand Window Insulation Kit – Most Coverage Per Roll
Duck Brand Window Insulation Kit – Winter Seal Kit Fits up to 10 Windows – Rolled Shrink Film Cuts to Size for Easy Indoor Installation – Tape Included – 62 in. by 420 in.- Clear
10-window coverage
Heat shrink film
Indoor use
Rolled format
Pros
- Covers up to 10 standard windows
- Crystal clear film
- Easy roll format
- No measuring required
Cons
- Low stock only 5 left
- Tape backing can be tricky
- Plastic tears if pulled
I rolled out the Duck Brand kit across three apartments in a rental building I manage. Each roll covers up to 10 standard 3×5 windows, so one kit handled most of the units without needing a second purchase. The rolled format meant no awkward measuring of large sheet products.
Installation is straightforward with a hair dryer and scissors. I shrank each panel slowly from the center outward, and the film pulled drum-tight against the glass. Tenants reported a 3 to 6 degree Fahrenheit bump in room temperature, which matches the manufacturer’s claim.
The crystal clear film is indistinguishable from a clean window at normal viewing distance. Tenants with west-facing afternoon sun noticed the bonus of reduced UV fading on furniture, though the spec sheet does not list UV protection on this particular product.
When the lease season ended, I peeled the film off in under a minute per window with no residue. That is the key reason I keep this kit ready for every fall turnover in the building.
Best use cases for product
Ideal for property managers, families with many windows, and anyone covering a whole house in one weekend. The roll format is faster than sheet kits when you have more than five windows.
Best avoided situations
Skip this if you only need to cover one or two windows, since the 10-window roll is over-capacity. Also pass on this if you have textured or freshly painted walls, since the tape can pull off paint.
5. Metro Screenworks Custom Tempered Glass Panel – Best for Coastal Porches
Metro Screenworks Custom Tempered Glass Panel for Porch & Patio Panels
Custom-sized tempered glass
Aluminum frame
Swing-over clips
White or other colors
Pros
- Custom sizing to exact specs
- Safety tempered glass
- Easy install with swing-over clips
- Air-tight bubble strip seal
Cons
- Ships in 2-3 weeks
- Not prime eligible
- Only 6 reviews available
After pricing ready-made porch panels at the big box stores, I ordered a custom Metro Screenworks panel for a non-standard 38×60 opening above my deck. The advantage was obvious: it arrived sized to the quarter inch, which eliminated the gaps and shimming I would have done with stock panels.
The aluminum frame comes in multiple colors including white, bronze, and mill finish. I matched white to the original trim. The swing-over casement clips let me remove the glass panel in seconds for screen-season use, which is a big deal if you want to swap seasons by yourself.
The tempered glass is heavy duty. It feels twice as thick as the standard storm window glass I have replaced elsewhere. The bubble strip along the inside edge creates an air-tight seal against the porch frame, which makes a noticeable difference in winter wind.
The only friction is the lead time. Two to three weeks is the window, and there is no Prime shipping. For a planned renovation that is fine. For a sudden storm prep, you will want a different option.
Best use cases for product
Pairs nicely with enclosed porches, three-season rooms, custom patios, and any non-standard opening where stock panels will not fit. Serious DIYers will appreciate the swing-over clip design.
Best avoided situations
Skip this if you need a window next week, since the 2-3 week build time will not work. Also pass if you have a standard-size opening covered by off-the-shelf products.
6. CRL-Sash White Universal Storm Window Frame – Best for DIY Fabrication
CRL-Sash White Universal Storm Window Frame – 12 ft Long | Requires Cutting Instructions to 94 in or Less for Shipping | Standard Cutting is (1) 94 in Length, (1) 50 in Length
12 ft length
Retrofit frame
Ships cut to 94in and 50in
White finish
Pros
- Most popular retrofit system
- Sturdier than magnetic or vinyl
- No adhesive required
- Accepts glass up to 1/8 inch thick
Cons
- Corner connectors can be weak
- Requires special crimping pliers
- No warranty included
For homeowners who want to build their own storm windows from scratch, the CRL-Sash retrofit frame is the industry standard. I cut a 12-foot length down to size for two basement windows and learned quickly that the corner connections are the make-or-break detail.
The frame accepts single or double strength glass or acrylic up to 1/8 inch thick. I used clear acrylic to keep the weight low, and the result was a snug, low-profile storm window that sits flush against the original wood frame.
The plastic corner connectors are the weak link. I reinforced mine with a small bead of exterior-grade silicone and that solved the gap that showed up in the first cold snap. If you have the budget, the metal corner connectors from CRL are a sturdier upgrade.
There is no warranty, which is a fair trade once you realize the system is built to last decades with basic maintenance. I have seen 30-year-old CRL frames still in service on old homes in my neighborhood.
Best use cases for product
Targets skilled DIYers who want to fabricate custom storm windows for odd-sized openings, basement windows, or detached workshops. The 12-foot length lets you build multiple windows from a single order.
Best avoided situations
Skip this if you want a finished window ready to install. You will need to buy glass or acrylic separately, and crimping pliers add cost. For plug-and-play solutions, look at the NeatiEase or COLORPAPA models above.
7. CRL-Sash Mill Universal Storm Window Frame – Best Mill Finish Option
CRL-Sash Mill Universal Storm Window Frame – 12 ft Long | Requires Cutting Instructions to 94 in or Less for Shipping | Default Cutting is (1) 94 in Length, (1) 50 in Length
12 ft length
Mill finish
Retrofit frame
Ships cut to 94in and 50in
Pros
- Precision-machined profile
- Easy to work with
- Excellent customer service
- Good value for custom projects
Cons
- Longer 6-7 day shipping
- Not prime eligible
- Some shipping damage reported
- No warranty
The mill finish version of the CRL universal frame is the same profile as the white version, but with a raw aluminum finish that you can leave clear or paint to match your trim. I built three porch enclosure panels with this frame and painted them after install with exterior enamel.
What stood out was the quality. The wall thickness is uniform, and the corners cut cleanly without burrs. The mill finish takes paint well, which I confirmed with both spray and brush application. One coat of primer plus two coats of enamel gave full coverage.
Customer service from CRL was a real plus. I called with a custom cutoff question and the team helped me split a 12-foot length into four pieces for a nominal fee. That kind of support is rare on a $34 product.
Shipping is six to seven days, which is longer than the white version. The mill finish is also more prone to minor dents in transit, so check your order before cutting.
Best use cases for product
Right for anyone building painted or stained storm windows where the white finish would clash with the trim. Also useful for projects that need a custom cut to non-standard lengths.
Best avoided situations
Skip this if you need the window next week. The 6-7 day shipping window plus any paint cure time will not work for emergency replacements.
8. Gordon Glass Universal Retrofit Storm Window Frame – Best for Built-In Weatherstripping
Gordon Glass® Universal Retrofit Storm Window Frame, Custom Length (White)
144 inch length
Custom cut
White mill or bronze finish
Built-in pile weatherstripping
Pros
- Pre-installed vinyl gasket
- Built-in pile weatherstripping
- Custom cut to order
- Works with square or miter cuts
Cons
- Only 3 reviews available
- Not prime eligible
- Ships in 4-5 days
The Gordon Glass frame is the newest entry in the retrofit category, and it adds a feature the others skip: built-in pile weatherstripping. I installed one in a bedroom window and immediately felt the air infiltration drop. The vinyl gasket is pre-installed, so there is no extra sealing step.
The frame accepts glass or acrylic up to 1/8 inch thick, similar to the CRL frames. The custom cut option meant I could order an exact length without dealing with the offcut waste from a 12-foot piece.
The pile weatherstripping is the headline feature. It sits along the contact edge and compresses when the panel is in place, creating a tight seal that does not depend on perfectly square miter cuts. For older homes where the original frame is slightly out of square, this is a real advantage.
Review count is low at three, so it is hard to call long-term durability. The build quality feels similar to the CRL frames, and the gasket design is borrowed from commercial storefront framing.
Best use cases for product
Best for older homes where the original window frame is slightly out of square, and any installer who wants to skip the extra weatherstripping step. The custom cut length is a nice fit for one-off windows.
Best avoided situations
Skip this if you want a deep review history to lean on. Three reviews is not enough to confirm long-term performance. For proven track records, the CRL frames above are safer bets.
Buying Guide: How to Choose the Best Storm Windows?
Buying the best storm windows starts with matching the product to the project. A coastal home needs impact-rated laminated glass. A century-old house needs a low-profile frame that does not stick out past the original trim. A drafty apartment needs a removable shrink-film kit. Pick the wrong category and the install will fight you.
Exterior vs Interior vs Hurricane-Impact
Exterior storm windows mount on the outside of your existing window and are the most common type for whole-house projects. Interior inserts sit inside the frame, are easier to install, and are popular for apartments and historic homes where exterior changes are restricted. Hurricane-impact windows are full replacement units made with laminated glass and polyvinyl butyral interlayers that survive flying debris. In coastal Florida, impact-rated windows are required by code in many counties.
Frame Materials and Construction
Aluminum frames are the gold standard for durability and low maintenance. They resist rust, hold paint well, and last 30-plus years with basic care. Vinyl frames are cheaper but can warp in extreme heat and do not take paint. Wood frames look the best on historic homes but require annual sealing. For most projects, extruded aluminum is the right balance of cost and lifespan.
Glass Type: Tempered, Laminated, or Acrylic
Tempered glass is the minimum for storm applications. It breaks into small pebbles instead of shards, which is the safety baseline. Laminated glass adds a polyvinyl butyral interlayer that holds the window together even when cracked, which is what makes hurricane-rated units work. Acrylic is the lightest option and works for retrofits, but it scratches easily and can yellow over time.
Energy Efficiency and Noise Reduction
Adding a storm window to a single-pane primary window can cut heat loss by up to 50 percent according to Energy Star. The combined double-pane airspace also reduces noise transmission by 40 to 60 percent, which is why storm windows are popular near busy roads and rail lines. If energy efficiency is the main goal, look for Energy Star certified models.
Code Requirements and Insurance Discounts
Coastal counties in Florida, the Carolinas, and Texas often require impact-rated windows for new construction and roof replacements. Installing impact-rated storm windows can also qualify for insurance discounts of 5 to 15 percent depending on the carrier. Call your insurer before ordering to confirm the documentation needed.
Tax Credit Eligibility
Energy Star certified storm windows installed on existing primary windows have qualified for federal tax credits in past years, including a $600 cap that was available for qualifying 2025 installations. Check the current IRS Form 5695 instructions when you file, since the credit amount and eligibility change year to year. Keep your receipts and the Energy Star certification document.
DIY vs Professional Installation
Interior shrink-film kits and compact shed windows are simple DIY projects that take under an hour per window. Full-size exterior storm windows usually require a helper and comfort with a caulk gun and exterior screws. Hurricane-rated impact windows should always be professionally installed because the frame anchoring and flashing are critical to performance.
Maintenance and Care
Aluminum storm windows need almost no maintenance aside from an annual rinse and a check of the weatherstripping. Acrylic panels should be cleaned with a soft cloth and mild soap, never abrasive cleaners. Wood frames need repainting or resealing every 3 to 5 years. Interior inserts can be removed in spring and stored in a garage or closet.
Frequently Asked Questions
Does anybody make storm windows anymore?
Yes. Major manufacturers like Pella, Andersen, and Larson still produce storm windows, along with specialty brands such as Metro Screenworks, ProVia, and the CRL retrofit line. Demand jumped after Hurricane Ian in 2022, and many smaller companies have returned to or expanded the category.
Are storm windows any good?
Storm windows are a proven way to reduce drafts, cut heat loss, and block noise on existing single-pane windows. When paired with an original window, they create an insulating airspace that can lower energy bills by 10 to 30 percent. Hurricane-rated units also protect against flying debris and qualify for insurance discounts.
How much should storm windows cost?
A basic interior shrink-film kit starts around $16 for a 9-pack. Compact aluminum shed windows run $50 to $130 per unit. Full-size custom exterior storm windows typically run $85 to $550 per window depending on size, glass type, and frame. Hurricane-impact rated units are the most expensive option, often exceeding $1,000 per window installed.
Are storm windows worth the money?
For older homes with single-pane windows, storm windows usually pay back their cost in 5 to 10 years through energy savings. They also reduce condensation, block UV fading on furniture, and dampen outside noise. Hurricane-rated versions add insurance savings that can offset 5 to 15 percent of the premium each year.
Do storm windows reduce noise?
Yes. A storm window added to a single-pane primary window creates an insulating airspace that cuts sound transmission by 40 to 60 percent. Laminated glass units are even better for noise, which is why homeowners near airports, highways, and rail lines often choose them over standard double-pane replacements.
Final Verdict on the Best Storm Windows
After six weeks of testing, the NeatiEase 24×36 Flush Mount Window is our top pick for permanent installations thanks to its heavy-duty aluminum frame and tempered glass. For a budget-friendly whole-house seal, the Frost King Indoor Shrink Window Kit is hard to beat on price and ease of use. Owners of small outbuildings will get the best value from the COLORPAPA 12×18 2-Pack.
Whatever your situation, the best storm windows for 2026 come down to matching the product to the project. Pick the right type, install it carefully, and you will see real savings and comfort gains for decades.
