Choosing a replacement window starts with the opening, not a feature list: a basement hopper, a double-hung window, and a single-hung window solve different problems. In this comparison, I rank the NOTASA 24 x 36 double-hung first for its two independently sliding sashes and tilt-in cleaning, the NOTASA 24 x 36 single-hung as a simpler alternative with similar glass and screen features, and the COLORPAPA hopper for compact basement or utility openings.

The main tradeoff is ventilation versus opening style and fit. Double-hung operation offers more ways to adjust airflow, while single-hung operation keeps movement to one sash. A hopper window is shaped for a short, wide opening and swings inward, which can be practical below grade but needs clear indoor space. All three use vinyl frames and insulated double-pane tempered glass, but none should be chosen by nominal size alone: measure the actual opening and confirm installation requirements before ordering.

Key Takeaways
- Best all-around operation: The NOTASA double-hung has independently sliding upper and lower sashes, giving it more ventilation flexibility than the single-hung pick.
- Simpler vertical-slider choice: The NOTASA single-hung retains tilt-in cleaning, a screen, and double-pane glass while limiting movement to one sash.
- Best for a short basement opening: The COLORPAPA hopper measures 32 x 14 inches and opens inward, so it suits a different opening shape and needs interior clearance.
- Shared basics matter: Each window lists vinyl framing, insulated double-pane tempered glass, and a drainage feature, but listed features do not replace checking installation details.
- Measure before choosing: The two NOTASA models are listed at 24 x 36 inches and the COLORPAPA at 32 x 14 inches; verify the rough opening, frame dimensions, and local requirements.

NOTASA 24 x 36 in. White Vinyl Double-Hung Window with Double-Pane Glass
I put the NOTASA double-hung first because it offers the widest range of everyday sash operation in this group. Its upper and lower sashes slide independently, so ventilation can come from either part of the window rather than only the movable lower sash. That distinction matters for buyers who want more control over how air enters and leaves a room. A built-in screen helps keep insects out when the window is open, while the tilt-in sash design supports cleaning from inside.
Its core materials are similar to the single-hung NOTASA: both are white vinyl, both list insulated double-pane tempered glass, and both include a screen and a rear drainage outlet. The double-hung earns the higher spot not because its glass is described as categorically better, but because its two moving sashes add ventilation flexibility. That extra operation can be useful in rooms where airflow options matter. It also means buyers should confirm how the sash mechanism is built and maintained, since the supplied description does not provide hardware details or performance ratings.
Compared with the COLORPAPA hopper, this is the more natural choice for a typical taller window opening rather than a short basement aperture. It does not swing inward as a hopper does, but it still needs suitable wall dimensions and installation clearance. The listed 24 x 36-inch size is not universal, and the package dimensions are larger than the nominal window size, so I would verify both the actual unit dimensions and rough-opening instructions before purchase. Its tilt-in cleaning claim is useful, though the description does not explain maintenance for every component.
This is the strongest pick for someone replacing a conventional vertical window who values selectable ventilation and indoor cleaning access. I would not choose it solely for generalized claims about energy or noise reduction: the description gives no tested ratings, and installation quality and glazing details matter. Buyers who want a more straightforward sash arrangement can choose the single-hung NOTASA instead; people fitting a low, wide basement opening should compare the COLORPAPA’s shape and inward swing.
Pros:- Independently sliding upper and lower sashes provide more ventilation arrangements than the single-hung NOTASA.
- Tilt-in sashes make indoor access for glass cleaning easier.
- Insulated double-pane tempered glass, a built-in screen, and a vinyl frame cover the main listed everyday-use features.
- Rear drainage outlet is designed to direct water away from the window.
Cons:- The listed 24 x 36-inch size may not match the home’s rough opening or replacement requirements.
- The description does not provide performance ratings, installation instructions, or detailed hardware-maintenance guidance.
- The cleaning description focuses on tilt-in sashes and does not spell out care for every window component.
Best for: Homeowners replacing a compatible 24 x 36-inch vertical window who want independent upper- and lower-sash ventilation, a screen, and tilt-in cleaning access.
Not ideal for: Buyers whose opening does not match the listed dimensions, who need a hopper-style basement window, or who require documented energy, sound, or code-performance ratings before selecting a unit.
- Window size:24 x 36 in.
- Window type:Double-hung
- Frame:White vinyl
- Glass:Insulated double-pane tempered glass
- Sash operation:Upper and lower sashes slide independently
- Cleaning:Tilt-in sashes
- Screen:Built-in
- Drainage:Rear drainage outlet
Our verdict“I rank this first for compatible vertical openings because its independently moving sashes offer more ventilation flexibility than the single-hung alternative.”
NOTASA White Vinyl Single-Hung Window, 24 x 36 in.
The NOTASA single-hung is the more restrained alternative to the double-hung model above. It keeps the same listed 24 x 36-inch format, white vinyl construction, insulated double-pane tempered glass, screen, tilt-in cleaning, and rear drainage outlet, but its vertical-sliding layout uses one moving sash. For a buyer who does not need both halves of a window to open, that simpler arrangement may be the better match. The tradeoff is clear: ventilation comes through the opened sash, rather than through independently adjustable upper and lower sections.
Because the shared materials and listed size are close to the double-hung’s, the choice is mainly about operation, not a major difference in the stated glass package. I rank it second because it gives up the double-hung’s ventilation options while retaining the useful cleaning feature. The tilt-in sash and included screen help it remain practical for routine use, and the vinyl frame is described as resistant to rust, UV rays, and harsh weather. Those are product claims, not a replacement for checking the unit’s test data or installation requirements.
The COLORPAPA is a less direct competitor: its 32 x 14-inch hopper is made for a short, wide opening, often in a basement or utility space. If the opening is tall and narrow enough for a vertical slider, the NOTASA may suit the shape better; if it is low and wide, forcing a single-hung format would be the wrong comparison. The single-hung also avoids the hopper’s inward swing, although opening still changes the window’s usable space and ventilation is limited to one sash.
I would favor this model when a homeowner wants a familiar vertical window and values tilt-in cleaning but has no strong reason to open the upper sash. It is not the right pick for someone seeking the broadest airflow arrangement in the lineup, since the double-hung offers more control. Nor should its nominal dimensions be treated as a guarantee of fit: the listing gives package dimensions larger than the window size, so I would confirm the product’s actual frame size, rough opening, and installation method before committing.
Pros:- Tilt-in sash supports cleaning from indoors.
- Included screen allows ventilation while helping keep insects out.
- Double-pane insulated tempered glass and reinforced vinyl framing are specified.
- Rear drainage outlet is designed to channel water outside.
Cons:- Only one sash moves, so ventilation options are more limited than on the double-hung NOTASA.
- The listed 24 x 36-inch size may not fit a particular rough opening.
- The listing does not provide quantified energy, sound, or air-leakage performance.
Best for: Buyers replacing a compatible 24 x 36-inch vertical window who prefer a single movable sash and want tilt-in cleaning and an included screen.
Not ideal for: Homeowners who want independent upper- and lower-sash ventilation, or anyone whose opening is better suited to a short, wide hopper window.
- Window size:24 x 36 in.
- Window type:Single-hung, vertical sliding
- Frame:Vinyl with reinforced framing
- Glass:Insulated double-pane tempered glass
- Sash operation:One vertical-sliding sash
- Cleaning:Tilt-in sash
- Screen:Included
- Drainage:Built-in rear drainage outlet
Our verdict“I recommend this as the simpler vertical-slider choice when a movable lower sash is enough and the opening does not call for a hopper.”
COLORPAPA Vinyl Hopper Basement Window, 32 x 14 in, White
The COLORPAPA hopper fills a different role from the two NOTASA windows. At 32 x 14 inches, it is a short, wide unit intended for openings that do not suit a standard vertical slider. Its inward-opening design offers ventilation without a sash projecting outside, a useful distinction where exterior space is constrained. The tradeoff is on the room side: the sash needs clear interior space to open, so furniture, shelving, or a narrow utility area could make operation awkward.
The listed construction includes a heavy-duty vinyl frame and insulated double-pane tempered glass, alongside a built-in drainage system. The description says the frame is intended to resist warping, cracking, and corrosion and does not need painting. Compared with the NOTASA picks, the COLORPAPA gives up their stated tilt-in cleaning arrangement and included screens, while emphasizing its compact hopper form and inward opening. The provided details do not specify a screen, so buyers who need one should verify whether it is supplied or available separately.
I place it third overall because it is more specialized by opening shape, not because a hopper is inherently a weaker replacement window. For a basement or utility opening measuring close to its stated format, its inward operation and drainage design may make more sense than either 24 x 36 vertical slider. For a taller conventional opening, the NOTASA double-hung or single-hung is the more appropriate style. These products are not interchangeable just because each has vinyl framing and double-pane glass.
Before choosing it, I would check exact frame and rough-opening dimensions, the direction and clearance of the inward swing, and any applicable egress or ventilation requirements. The listing gives the window as 32 x 14 inches and the product dimensions as 32 x 14 x 3 inches, but installation compatibility still depends on the existing opening and how the unit is fitted. Its stated materials provide a useful starting point; the supplied description does not include performance ratings, installation steps, or warranty information.
Pros:- Compact 32 x 14-inch hopper format targets openings unlike the taller NOTASA windows.
- Inward opening provides ventilation without a sash projecting outside.
- Double-pane insulated tempered glass and heavy-duty vinyl frame are specified.
- Built-in drainage system is designed to direct water away from the frame.
Cons:- The inward-opening sash needs clear space inside the room.
- The description does not list a screen or tilt-in cleaning feature.
- The stated dimensions may not fit an existing opening, and installation details are not provided.
Best for: Homeowners replacing a compatible short, wide basement or utility-room opening who want an inward-opening hopper and a vinyl frame.
Not ideal for: Buyers with a conventional tall vertical opening, limited indoor clearance, or a need for a confirmed included screen or tilt-in cleaning feature.
- Window size:32 x 14 in.
- Window type:Hopper
- Frame:Heavy-duty vinyl
- Glass:Insulated double-pane tempered glass
- Opening direction:Inward
- Drainage:Built-in drainage system
- Color:White
- Weight:17.96 lb
Our verdict“I would choose this over the vertical sliders only when the opening suits a hopper and there is room inside for its inward swing.”
How We Picked
I ranked these three products by how well their stated features match common replacement-window jobs, rather than treating them as interchangeable. The list includes two vertical-sliding windows and one hopper, so my first question was whether each design fits a distinct opening and ventilation need. The double-hung ranks first because its upper and lower sashes move independently, creating more ways to manage airflow than the single-hung design. That flexibility makes it the broadest fit among these specific options, though it does not make it suitable for every opening.
I also compared glass, cleaning access, screens, drainage, and frame material. All three listings describe insulated double-pane tempered glass and vinyl frames, which gives buyers a common baseline. The NOTASA models specify tilt-in cleaning and included screens; the COLORPAPA description emphasizes inward opening and built-in drainage. These details affect daily use, but I do not treat general claims about comfort or durability as a substitute for verified performance ratings, installation guidance, or local code checks.
Fit and operation carry the most weight in my ranking. A 24 x 36 vertical slider cannot be swapped automatically for a 32 x 14 hopper simply because both are white vinyl windows. I also account for the downsides: inward swing needs interior clearance, the single-hung sash offers fewer ventilation configurations, and a listed size may not match a home’s rough opening. The product information provided does not specify performance ratings, warranty terms, or a full installation method, so I leave those questions for buyers to confirm with the seller or installer.

Factors to Consider When Choosing Best Replacement Windows
I would choose among these replacement windows in this order: confirm the opening and installation requirements, choose the window style that works in that space, then compare the included features. A window can have suitable glass and frame materials yet still be the wrong replacement if its size, swing, or operation conflicts with the room.
Start with the opening and installation method
Measure the existing window and opening carefully, and distinguish the actual unit dimensions from the rough opening required by the installation. The two NOTASA models are listed as 24 x 36 inches; the COLORPAPA is listed as 32 x 14 inches. Those numbers point to different shapes, but the product details supplied here do not fully explain installation tolerances or whether the listed size refers to the frame, sash, or another measurement convention. Confirm the manufacturer’s installation instructions and have a qualified installer assess the opening when needed. Check for rot, water damage, out-of-square framing, and any work required around the trim before ordering. A replacement window is a poor fit if it only matches the visible glass area but not the prepared opening.
Match the window style to how you use the room
The double-hung NOTASA offers independent upper- and lower-sash movement, making it the most flexible of these three for choosing where air enters and exits. The single-hung NOTASA keeps a vertical-slider format but limits movement to one sash, which suits buyers who do not need the extra opening arrangement. The COLORPAPA hopper is a different shape and operation: it opens inward and is aimed at a short, wide opening such as one in a basement or utility space. Think about nearby furniture, counters, walkways, and exterior obstructions. The hopper’s interior clearance needs can decide the choice before its glass or frame does.
Understand the glass claims without assuming a performance rating
All three products describe insulated double-pane tempered glass. Double glazing is intended to reduce heat and sound transfer compared with a single pane, but the supplied product details do not include measured energy, air-leakage, or acoustic ratings. I would not use a general description as proof that a window meets a particular climate, energy code, or noise-control goal. Ask for applicable performance documentation and confirm the glass configuration, spacer, and any coatings with the seller or installer. Tempered glass is a stated construction detail, but the exact requirements for a particular opening can depend on location and building rules.
Compare cleaning access, screens, and ventilation
For routine upkeep, the two NOTASA descriptions specify a tilt-in sash, which can make the glass easier to reach from indoors. The double-hung offers the more adjustable ventilation arrangement; the single-hung trades that flexibility for a one-sash design. Both list a screen. COLORPAPA emphasizes inward opening instead, and its supplied details do not list a screen or tilt-in cleaning feature. Confirm those items if they matter to your room. Also ask whether screens are removable for cleaning and how the sash operates in practice, since product summaries do not describe every maintenance step or hardware detail.
Check frame, drainage, and exposure conditions
Each pick uses a vinyl frame and lists a drainage feature: a rear outlet on the NOTASA models and a built-in drainage system on the COLORPAPA. These features are intended to manage water, but they do not remove the need for correct flashing, sealing, and installation. Compare the window’s exposure to wind-driven rain, direct sun, and temperature extremes, and ask for documentation that matches local conditions. Vinyl can reduce the need for painting compared with some frame materials, but long-term performance depends on frame construction, installation, and care. Do not assume that a drainage outlet can compensate for a poorly prepared or incorrectly sealed opening.
Confirm code, warranty, and installer requirements
Before purchase, check whether the window must meet local rules for ventilation, safety glazing, energy performance, or emergency escape. Basement openings can have specific requirements, so the hopper’s compact form should not be treated as proof that it meets any egress requirement. The product information here does not state warranty coverage, certified performance ratings, or complete installation directions. I would request those details, confirm who handles damage or missing parts, and agree on installation responsibilities before ordering. For a replacement that affects exterior water management or a required escape opening, use a qualified professional familiar with local codes.
Frequently Asked Questions
Which of these replacement windows is the most versatile?
Among these three, I rank the NOTASA double-hung as the most versatile for a compatible vertical opening because its upper and lower sashes move independently. That gives it more ventilation arrangements than the single-hung model. It is not automatically the right choice for every room: the opening must fit, and a short, wide basement opening may be better matched to the COLORPAPA hopper.
What is the difference between the NOTASA double-hung and single-hung windows?
The double-hung has independently sliding upper and lower sashes, while the single-hung has one vertically sliding sash. Both listed NOTASA models are 24 x 36 inches and include double-pane tempered glass, a screen, tilt-in cleaning, and a rear drainage outlet. I would pick the double-hung for more ventilation control and the single-hung when one moving sash is enough.
Is the COLORPAPA hopper a suitable replacement for a standard vertical window?
Not usually without an opening that matches its 32 x 14-inch hopper format. It is designed for a shorter, wider space and opens inward, while the NOTASA models are vertical sliders listed at 24 x 36 inches. Compare the actual frame and rough-opening measurements, then check that the inward sash has room inside. A window style should match the opening and its use rather than being selected by material alone.
Do these windows have documented energy or sound ratings?
The supplied descriptions say that all three use insulated double-pane tempered glass and describe benefits such as reduced heat or noise transfer. They do not provide quantified energy, air-leakage, or acoustic ratings. If a specific performance level matters for your climate or location, ask for product documentation and verify it against local requirements rather than relying on general feature claims.
What should I measure before buying a replacement window?
Confirm the existing unit and rough-opening dimensions, including width and height at more than one point, and check whether the opening is square and sound. Also verify the exact product frame dimensions, installation method, trim needs, and swing clearance. The listed dimensions for these products differ substantially, and a nominal 24 x 36 or 32 x 14 measurement alone does not confirm a fit. Ask the seller or installer to clarify measurement conventions before ordering.
Conclusion
My pick depends first on the opening and then on how you want the window to operate. For a compatible vertical opening where adjustable ventilation matters, I would choose the NOTASA double-hung; it ranks first because both sashes move independently, and it also lists tilt-in cleaning and a screen. For someone who wants a straightforward vertical slider and does not need both sashes to move, the NOTASA single-hung is the simpler alternative. If the job is a short, wide basement or utility opening with room for an inward swing, the COLORPAPA hopper is the more relevant shape.
I would not order any of them until the opening dimensions, installation method, and local code requirements are checked. The product descriptions give useful differences in sash operation, glass, screens, and drainage, but they do not provide complete performance ratings or installation guidance. Choose by fit and intended use first; then confirm the details that the listing does not establish.
