A 27 x 30 window is available in several styles, but check the listed dimensions, frame type, and installation opening before ordering. The Kinro 30 x 27 model is best for mobile-home replacement; the 30 x 27 aluminum slider suits basement or shed ventilation; and the 27 x 30 household window offers a close match for its stated size. The other options below have different dimensions, so they may not fit a 27 x 30 opening without a suitable redesign or adjustment.
| Product | Listed size | Best suited for |
|---|---|---|
| Kinro mobile-home window | 30 x 27 inches | Mobile-home replacement |
| Basement and shed aluminum window | 30 x 27 inches | Ventilation and sliding operation |
| Household sliding window | 27 x 30 inches | Basements, sheds, and garages |
| NeatiEase shed windows, two-pack | 30 x 30 inches each | Sheds and outbuildings |
| NOTASA vinyl single-hung window | 24 x 36 inches | Buyers needing a different opening size |
Kinro 30 X 27 Mobile Home Window
This Kinro window is the strongest match for a mobile-home replacement project among the listed options. Its dimensions are 30 x 27 inches, which is the same nominal size as 27 x 30 when the orientation is reversed. Confirm which dimension is width and which is height, and compare the product measurements with the existing opening before purchase.
The window has a vinyl frame, 3/4-inch insulated Thermopane glass, a lower tilt sash, and an included screen. Its built-in nail or screw flange is intended to support installation. Choose this model if you need an insulated mobile-home window with a tilt-in lower sash. A limitation is that the listing identifies it for mobile homes, so buyers seeking a standard shed or house window should verify suitability for their project.
Aluminum 30 X 27 Sliding Window
This 30 x 27 window is designed for basements, sheds, and similar spaces where horizontal sliding operation is useful. It has an aluminum alloy frame, 5 mm tempered glass, and a removable screen made with 304 stainless steel mesh. The sliding panels are described as allowing natural light and ventilation.
Choose this option if you want a sliding window with a metal frame and screen for a basement or outbuilding. The listing also states an IP65 waterproof rating and describes the frame as rust- and corrosion-resistant. A caution: its 30 x 27 listed size may not match an opening measured as 27 inches wide by 30 inches tall. Verify the orientation and full frame dimensions first.
Household 27 X 30 Sliding Window
This product’s listed 27 x 30-inch dimensions align directly with the keyword size. It is intended for homes, basements, sheds, garages, and other spaces. The aluminum frame is described as rust-resistant, while the dual-track design supports sliding adjustment. Its split-panel layout has a fixed upper pane and a lower pane that slides inward with an insect screen.
It is best for buyers who want a 27 x 30 sliding design for ventilation in an enclosed room or outbuilding. The listing specifies tempered glass and a screen, which may help address safety and insect-entry concerns. The main limitation is that the product description does not provide installation-opening measurements, so check the actual frame and rough-opening requirements with the seller before ordering.
NeatiEase Two-Pack 30 X 30 Shed Windows
This two-window set is better suited to sheds, chicken coops, playhouses, and garages than to a 27 x 30 replacement opening. Each window is listed as 30 x 30 inches and features an aluminum frame, tempered glass, and 304 stainless steel wire mesh. The seller describes the mesh as a barrier against insects and larger animals.
Choose this product if you need two square windows for an outbuilding and value the stainless steel screen. The listing also highlights ventilation and sunlight. Avoid it if your opening is already sized for a 27 x 30 window unless you have confirmed that the larger square frame will fit; its dimensions differ from the target size.
NOTASA 24 X 36 Vinyl Single-Hung Window
This window is included as an alternative for buyers comparing operating styles, not as a direct 27 x 30 match. Its listed size is 24 x 36 inches. Features include double-pane insulated tempered glass, a rear drainage outlet, and a tilt-in sash intended to make cleaning easier from inside the home.
It is best for someone whose project calls for a 24 x 36 single-hung vinyl window and who wants insulated glazing. The listing describes benefits for temperature control and outside-noise reduction. Do not choose it as a drop-in replacement for a 27 x 30 opening without confirming the required frame size and installation details; the dimensions are different.
Buying Guide: How To Choose A 27 X 30 Window
Should you match the window size or the rough opening?
Start by measuring the existing window frame and the rough opening separately. A product’s stated size may refer to the window itself rather than the opening needed for installation. Check the manufacturer’s measurement instructions and confirm whether 27 x 30 means width by height. A 30 x 27 listing may be the same dimensions in the opposite orientation, but it is not safe to assume that without checking.
Which frame and glass type fit the project?
Vinyl options in this list include insulated glass and are aimed at home or mobile-home use. Aluminum models are listed for basements, sheds, and other utility spaces. Tempered glass appears on several products, while the Kinro model specifies 3/4-inch insulated Thermopane glass. Compare the stated materials and intended use with the conditions at the installation site.
Do you need a sliding or tilt-in sash?
Sliding windows open horizontally or vertically, depending on the model, and can support airflow without a sash swinging into the room. Tilt-in sashes are useful when interior access for cleaning is important. Confirm the exact operating direction and which panels move before purchasing.
What screen details should you compare?
Check whether a screen is included, removable, and made from the material you need. The listed choices include standard screens, fiberglass screening, and 304 stainless steel mesh. Do not assume that every screen provides the same level of resistance to insects or animals.
Frequently Asked Questions
Is a 30 x 27 window the same size as a 27 x 30 window?
The two measurements contain the same numbers but may indicate different width and height orientations. Confirm the product’s orientation and actual frame measurements before ordering.
Which listed window is closest to a 27 x 30 opening?
The household sliding window is listed as 27 x 30 inches. The Kinro and aluminum sliding options are listed as 30 x 27 inches, so verify orientation and fit.
Which option is intended for a mobile home?
The Kinro product is explicitly described as a mobile-home replacement window. Check its flange and installation requirements against the existing opening.
Are any of these windows sold as a two-pack?
Yes. The NeatiEase listing is for two 30 x 30-inch shed windows. Their size is larger and squarer than a 27 x 30 window.
Can the 24 x 36 window replace a 27 x 30 window?
Not as a direct size match. Its listed dimensions differ, so use it only if the project opening is appropriate or the installation can be redesigned.
