A strong greenhouse covering should provide clear light, suit the roof or wall dimensions, and offer weather protection appropriate to its installation. For growers covering a larger area, the polycarbonate roofing panels in this selection are more directly suited to greenhouse use than the small acrylic craft and replacement sheets. They include formats from 1.97 x 6.56 feet to 4 x 26.2 feet, plus a 2 x 10-foot panel option.
The listed products vary in thickness, material descriptions, and stated UV or impact resistance, so check the details rather than assuming all clear sheets perform alike. This roundup ranks the purpose-made roofing panels first and keeps smaller acrylic and polycarbonate sheets for patching, small builds, or projects where their dimensions are a better match.
The best fit for most greenhouse-covering projects here is HHFSST Clear Roof Panels. Its listed 2 x 10-foot format is intended for greenhouses and agriculture, and the product states up to 85% light transmittance, UV resistance, and impact resistance. It is described as about 0.3 inches thick, though another specification gives about 0.05 inches, so verify the delivered panel thickness before designing a frame.
If you need a different sheet size or a roll-like long format, compare the other purpose-listed polycarbonate roofing panels.

Detailed Reviews: Best Acrylic Sheet For Greenhouse
Why it ranks #1: The 2 x 10-foot panels are listed for greenhouses and agriculture, with stated 85% light transmittance, UV resistance, and impact resistance.
A 2-by-10-foot format is the clearest differentiator of HHFSST’s transparent polycarbonate roof panels, helping cover a longer greenhouse run with fewer individual sheets. The listing also describes high transparency, up to 85% light transmittance, impact resistance, and waterproofing, positioning this sheet for light-facing outdoor coverage.
The 196.8-by-39.4-inch listed dimensions provide a long sheet format for greenhouse or agricultural roofing layouts, while the easy-to-cut description supports shaping panels for a project. Light transmittance is specified as up to 85%, linking its transparency to natural-light use. The listing also calls the material waterproof, bendable, and impact-resistant, which may help with fitting and outdoor coverage. Internal reinforcement is described as adding toughness and load-bearing capacity.
- Large 2-by-10-foot sheet format
- Light transmittance listed as up to 85%
- Described as easy to cut and bendable
- Waterproof with internal reinforcement for added toughness
- A 2-by-10-foot sheet can be awkward to handle and store in a small workspace.
Skip it if you need compact individual panels for small openings; KINLINK’s 24-by-36-inch PET sheets are smaller pieces.
Pick this long-format panel for greenhouse roofs or agricultural projects where a broad sheet and high light transmission suit the layout. Its size can simplify coverage, but measure handling and storage space before bringing it into a smaller work area.

#4 · Impact Resistant
4. CghhDY Greenhouse Panels
- dimensions: 4"L x 1"W x 1"H
- Material: Polycarbonate (PC)
Best for: Impact-Resistant Light Panels.
Why it ranks #4: These clear polycarbonate panels are explicitly presented for greenhouses and state high impact resistance, rainproofing, and suitability for natural-lighting roofs.
CghhDY highlights impact resistance far beyond glass and acrylic as the defining feature of its clear polycarbonate greenhouse panels. The listed 3.28-by-6.56-foot size offers a substantial sheet for natural-light coverage, while rainproofing, sun protection, and resistance to breaking support outdoor panel use.
The 3.28-by-6.56-foot size gives greenhouse builders a sizable clear panel for roof or wall lighting areas, and the product is described as lightweight for building-material use. Polycarbonate construction is associated with high light transmission and waterproofing, so the sheet can admit natural light while serving as a rain-facing cover. The listing also describes it as rainproof and sunproof, with impact resistance intended to reduce shattering concerns when struck by heavy objects.
- 3.28-by-6.56-foot clear panel size
- Polycarbonate material for light-transmitting coverage
- Described as rainproof and sunproof
- Impact resistance is described as exceeding glass and acrylic panels
- The supplied listing gives no panel thickness specification for installation planning.
Skip it if you need a stated thickness before laying out supports; Altovexis’s clear polycarbonate sheet specifies a 1 mm thickness.
Choose these panels for greenhouse lighting coverage where a sizable sheet, rain protection, and impact resistance matter. Check the project layout against the 3.28-by-6.56-foot size, and note that thickness is not specified in the supplied details.

View on AmazonWhy it ranks #5: The clear polycarbonate roofing panels are listed for greenhouse use and claim UV protection, waterproofing, hail resistance, and impact resistance.
Built-in UV protection paired with impact resistance defines these clear polycarbonate roofing panels, offering greenhouse builders a daylight-transmitting covering with weather-oriented features. The listing also specifies waterproofing, thermal insulation, cold resistance, anti-aging properties, and hail resistance, framing the panels for use where exposure and natural light matter.
The highly transparent polycarbonate is described as comparable to glass, so it supports natural lighting while serving as a roofing material. Built-in UV protection and anti-aging properties address outdoor exposure, while waterproofing is relevant to rain-facing greenhouse coverage. Impact and hail resistance, plus shatter resistance, speak to a more resilient panel choice around flying debris. Thermal insulation and cold resistance are also listed, making those features relevant when selecting coverage for changing conditions.

6. Robosource Polycarbonate Sheet
- dimensions: 36 x 36 x 0.06 in
- Material: Acryllic, Glass, Polycarbonate, plastic…
- Form: Sheet
Best for: Workshop-Cut Polycarbonate Sheet.
Why it ranks #6: This 36 x 36-inch, 1/16-inch polycarbonate sheet is shatter resistant and easy to cut, drill, and bend, but is not specifically listed as roofing.
Easy cutting, drilling, bending, and thermoforming make Robosource’s 36-by-36-inch polycarbonate sheet a practical choice for greenhouse builders who fabricate their own panels. Its 1/16-inch thickness and shatter-resistant material are clearly specified, while protective film helps preserve the clear surface through measuring and workshop handling.
The 36-by-36-inch sheet provides a square format for planning a small panel or cutting several smaller pieces. At 1/16 inch thick, it is a thin sheet that can be worked with snips or hacksaws, and the listing also supports drilling, bending, and thermoforming with simple tools. Polycarbonate is described as shatter-resistant and workable without cracking or chipping. EasyRuler protective film stays on during fabrication and peels away to expose the clear surface.
- 36-by-36-inch clear polycarbonate sheet
- 1/16-inch thickness is specified
- Can be cut, drilled, bent, and thermoformed
- Protective film peels off after fabrication
- At 1/16 inch thick, this sheet is a thin option for greenhouse panel projects.
Skip it if you need thicker individual clear pieces for small openings; KAITELA’s 1/4-inch cast acrylic sheets offer a thicker format.

7. KINLINK PET Sheets
- dimensions: 24 x 36 x 0.13 in
- Material: Polyethylene Terephthalate
- Form: Sheet
Best for: UV-Coated PET DIY Panels.
Why it ranks #7: The 24 x 36-inch, 1/8-inch clear PET sheets have stated UV resistance, but their size and material description suit small projects better than greenhouse roofing.
An anti-ultraviolet coating is the defining feature of KINLINK’s clear PET sheets, giving greenhouse DIYers a UV-resistant option in a familiar 24-by-36-inch format. The 1/8-inch sheets arrive as a two-pack, while protective surface paper helps keep fingerprints, stains, and scratches off during handling and project preparation.
The 24-by-36-inch format gives you sizable sheets to lay out for a small greenhouse project, and the 1/8-inch thickness identifies the material you’ll be working with. PET construction is specified as recyclable, non-toxic, and environmentally friendly, while the anti-UV coating adds UV resistance. Protective paper is useful during cutting or fitting because it guards the face from scratches, stains, and fingerprints; peel it away when the sheet is ready for use.
- Two clear 24-by-36-inch sheets per pack
- 1/8-inch PET construction
- Anti-ultraviolet coating provides UV resistance
- Protective paper guards against scratches, stains, and fingerprints
- The 1/8-inch sheet format may require support or joining for larger greenhouse spans.
Skip it if you need a large continuous roofing panel; HHFSST’s 2-by-10-foot sheet covers a longer run.
Choose this two-pack for greenhouse repairs or DIY projects that suit individual 24-by-36-inch PET sheets. Its UV coating and protective paper help with outdoor-oriented preparation, but plan around the sheet size and 1/8-inch thickness.

8. KAITELA Cast Acrylic Sheets
- dimensions: 12 x 16 x 0.24 in
- Material: Acrylic
- Form: Sheet
Best for: Small Cast Acrylic Greenhouse Panels.
Why it ranks #8: Four 12 x 16-inch, 1/4-inch cast acrylic sheets offer stated UV resistance and weatherability, but their small format is poorly suited to covering a greenhouse.
Laser-cut clean edges with no chips distinguish KAITELA’s clear cast acrylic sheets for greenhouse DIYers who want ready-finished small panels. The four-pack contains 12-by-16-inch sheets at 1/4-inch thickness, with glass-like clarity, weatherability, and UV resistance listed for the acrylic material.
Four 12-by-16-inch sheets provide several compact pieces for greenhouse windows, inserts, or related projects, while the 1/4-inch thickness offers a defined board profile. Cast acrylic is described as having glass-like clarity and UV resistance, relevant for a transparent outdoor-facing component. The sheets can be cut, sawed, drilled, routed, laser cut, painted, or hot bent, giving fabricators several ways to adapt them. Kraft protective paper is included on the sheets.
- Four clear 12-by-16-inch sheets
- 1/4-inch cast acrylic thickness
- Glass-like clarity with UV resistance and weatherability
- Supports cutting, drilling, routing, laser cutting, and hot bending
- The 12-by-16-inch format is limited for greenhouse roofs that need large continuous panels.
Skip it if you need a long roof sheet rather than small pieces; GHTCLDF’s 1.97-by-6.56-foot polycarbonate sheet covers a larger run.
This pack suits greenhouse builders making compact clear panels or custom inserts with several fabrication options. Its cast acrylic clarity and 1/4-inch thickness are useful considerations, while the 12-by-16-inch dimensions limit broad coverage.

9. Performore Acrylic Sheet
- Material: acrylic
- Form: Sheet
Best for: Acrylic Boards for Small Openings.
Why it ranks #9: The clear acrylic sheet measures 12 x 24 inches and is described for indoor and decorative uses, with no greenhouse roofing specifications provided.
A 12-by-24-inch footprint and 1/4-inch thickness define Performore’s clear acrylic sheet for greenhouse builders needing a manageable board rather than a roofing-length panel. The acrylic is described as glass-like, durable, and shatter-resistant, with lighter-than-glass handling and easy cleaning noted for practical applications.
The 12-by-24-inch sheet gives a compact rectangular piece for a small greenhouse opening, partition, or decorative panel, while its 1/4-inch thickness is specified for layout planning. Acrylic’s glass-like qualities support clear viewing, and the listing describes it as lighter than glass and shatter-resistant. Easy cleaning and maintenance are also noted, which can help when the sheet is used in areas exposed to spills or stains. The listed use cases also include indoor decoration and product design.
- Clear 12-by-24-inch acrylic sheet
- 1/4-inch thickness
- Described as lighter than glass and shatter-resistant
- Easy to clean and maintain
- The 12-by-24-inch board is a compact format, not a long greenhouse roofing sheet.
Skip it if you need a long transparent roof covering; Altovexis’s 4-by-26.2-foot polycarbonate sheet is sized for extended runs.
Use this board for a small greenhouse window, partition, or other compact clear component where a 12-by-24-inch acrylic piece fits. Its 1/4-inch thickness and stated easy-clean surface suit panel work, not broad roof coverage.

10. KINLINK Cast Acrylic Sheets
- dimensions: 12 x 12 x 0.25 in
- Material: Acrylic
- Form: Sheet
Best for: Small Thick Acrylic Greenhouse Inserts.
Why it ranks #10: These 12 x 12-inch, 1/4-inch acrylic sheets are described for DIY projects rather than greenhouse roofing, making their small format the least suitable.
A 1/4-inch thickness distinguishes KINLINK’s clear cast acrylic sheets, giving small greenhouse inserts a thicker board format than thin roofing sheets. The two-pack measures 12 by 12 inches per sheet, and protective paper covers the surface to help prevent scratches, stains, and fingerprints during project preparation.
Each 12-by-12-inch sheet offers a compact size for small greenhouse openings, sample panels, or DIY components rather than broad roof coverage. The 1/4-inch acrylic thickness supplies a clearly stated board profile, while the manufacturer describes the material as durable, lightweight, and non-toxic. An ultra-clear surface supports visibility through the sheet, and protective paper helps keep the face clean during handling. The listing also mentions suitability for laser cutting, useful for custom-shaped work.
- Two clear 12-by-12-inch sheets
- 1/4-inch acrylic thickness
- Ultra-clear surface
- Protective paper guards against scratches, stains, and fingerprints
- The 12-by-12-inch sheet size is too small for covering broad greenhouse roof sections without joins.
Skip it if you need long continuous greenhouse coverage; HHFSST’s 2-by-10-foot polycarbonate sheet spans a much longer run.
Consider this two-pack for small greenhouse windows, inserts, or acrylic DIY components where a 12-inch square and 1/4-inch thickness fit. It is not a broad roofing format, so plan the layout around its compact dimensions.

View on AmazonAvoid a thickness and coverage mismatch
Confirm the stated thickness and usable coverage before building or modifying a greenhouse frame. The product data can contain inconsistencies: HHFSST lists a thickness of about 0.3 inches in its features but gives a 0.05-inch product dimension, while its size is stated as 2 x 10 feet and its dimensions as 196.8 x 39.4 inches. Those figures do not fully agree, so check the actual panel and seller details before choosing fasteners or spacing supports.
Also distinguish a small sheet from a roofing panel: the 36 x 36-inch Robosource sheet and 12 x 16-inch KAITELA sheets may suit repairs or small enclosures, but they do not cover the same area as the multi-foot roofing formats. Measure the frame opening and account for overlaps and attachment edges; product dimensions alone do not specify the finished coverage after installation.
Polycarbonate is not acrylic
Most products presented as greenhouse roofing in this selection are polycarbonate, not acrylic. That distinction matters when matching a replacement panel or comparing material requirements: the product titles sometimes use acrylic terminology, but the listed material for the roofing options includes polycarbonate. The acrylic products are small cast sheets, including KAITELA’s 12 x 16-inch panels and KINLINK’s 12 x 12-inch pair, while the purpose-listed roof options reach several feet in length.
Polycarbonate roof products also make specific claims such as UV protection, impact resistance, or rainproofing, but the details differ by listing. Do not assume that a clear sheet is automatically interchangeable with an existing greenhouse panel.
Verify the material, dimensions, thickness, and mounting arrangement against your structure, especially when replacing only one panel in a system designed around a particular profile.
How to Choose Greenhouse Sheets
Panel size and coverage
Choose a panel format that covers your frame with manageable seams and edges. Listed roofing sizes range from GHTCLDF’s 1.97 x 6.56-foot panels to HHFSST’s 2 x 10-foot panels and Altovexis’s 4 x 26.2-foot sheet. Smaller sheets include Robosource’s 36 x 36-inch panel and KAITELA’s 12 x 16-inch sheets.
Measure the structure before ordering and allow for the actual mounting layout; the listings do not specify finished coverage after overlaps. Buyers covering a substantial roof should favour the larger purpose-listed formats, while someone repairing a small opening may find a smaller sheet easier to handle.
Material and intended use
Match the material and stated use to the job rather than relying on a product title that calls a panel acrylic. The main greenhouse roofing options identify polycarbonate, while KAITELA, Performore, and KINLINK list acrylic sheets; KINLINK’s 24 x 36-inch option is PET. Several polycarbonate listings explicitly mention greenhouse roofing, whereas the smaller acrylic products describe craft, indoor, or general DIY uses.
A buyer replacing greenhouse roof panels should start with products listed for roofing and confirm that their material suits the existing frame. For small cut-to-size projects, the acrylic or PET sheets may better suit the task, but their stated dimensions make them less practical for broad roof coverage.
Thickness and stated protection
Compare thickness and the specific protection claims, and verify conflicting details before installation. Altovexis lists a 1 mm polycarbonate roofing sheet; Robosource lists a 1/16-inch polycarbonate sheet, and the KINLINK PET option is 1/8 inch thick. HHFSST describes about 0.3 inches in its features but gives about 0.05 inches in its dimensions, so its thickness needs confirmation.
UV or impact claims also vary: HHFSST states UV and impact resistance, while GHTCLDF lists UV and aging resistance. Buyers exposed to hail or strong weather should prioritize panels whose listing states relevant protection, then confirm installation compatibility; small project users may prioritize a thickness and size they can cut and handle.
Which greenhouse sheet should you choose?
For a greenhouse roof covering a larger area, choose HHFSST Clear Roof Panels first: its 2 x 10-foot format is listed for greenhouse and agricultural use, with stated UV and impact resistance. Confirm its conflicting thickness information before ordering. If you need a shorter panel, GHTCLDF Polycarbonate Panels offer a 1.97 x 6.56-foot greenhouse roofing format.
For long roof runs, Altovexis Roofing Sheet provides a 4 x 26.2-foot size and a stated 1 mm thickness. CghhDY Greenhouse Panels and YBCNXWPSZ Roof Panels are other purpose-listed polycarbonate options.
Choose Robosource Polycarbonate Sheet for a smaller shatter-resistant cut-and-drill project. The acrylic and PET products are better treated as small project or repair materials, not default choices for covering a full greenhouse.

Frequently Asked Questions
How should greenhouse panels be fastened to prevent wind or rain from entering?
Use the panel maker’s recommended fasteners and installation method, and secure panels to a frame with edges and joints carefully aligned. Seal joints with a material compatible with the panel, while allowing for any movement the instructions specify. Product details here do not provide fastening instructions, so confirm them before building or installing.
Does a clear greenhouse panel need UV protection on one side or both?
Check the product instructions or markings for whether UV protection is one-sided or provided throughout the panel. The HHFSST listing states UV resistance but does not specify which side is protected. Do not assume the panel is reversible; orient it as directed by its manufacturer, and ask the seller if the instructions are unclear.
How much light transmission do greenhouse plants need?
There is no single light-transmission figure that suits every plant or greenhouse. Consider the needs of the crops and growing conditions, then compare those with a panel’s stated transmission. The HHFSST listing claims up to 85% light transmittance; the supplied titles do not give comparable transmission figures for the other options.
What should I check before choosing a panel thickness?
Match the panel to the frame and installation requirements, and verify the delivered thickness before designing around it. The HHFSST listing is inconsistent: it describes the panel as about 0.3 inches thick, while another specification gives about 0.05 inches. Its published verdict specifically advises confirming thickness before ordering.
Which listed panels suit a large greenhouse roof or a small repair?
For a larger roof, the published verdict favors HHFSST Clear Roof Panels, listed in a 2 x 10-foot format for greenhouse and agricultural use. It points to the 4 x 26.2-foot Altovexis sheet for long runs and Robosource for smaller cut-and-drill projects. Acrylic and PET sheets are better treated as small-project or repair materials.
Final Words
For most greenhouse-covering projects in this selection, start with HHFSST Clear Roof Panels: the listing identifies greenhouse use, a 2 x 10-foot format, UV resistance, impact resistance, and up to 85% light transmittance. Verify its conflicting thickness information before planning the frame. Compare GHTCLDF for a shorter panel or Altovexis for a long run; reserve acrylic and PET sheets for smaller projects or repairs.
