Buying guide: choosing the best acrylic sheets 1/2 inch thick
Thickness and size
All four sheets are 1/2 inch thick: the SimbaLux sheet states 13mm nominal, from 12.7mm to 13.3mm, while the Fab Glass sheet states 12mm. Sizes run from 12 by 12 inches for the SimbaLux sheet, through 24 by 48 inches for the CALPALMY 2-pack, to 48 by 96 inches for the Fab Glass sheet, which states 32 square feet against 16 square feet for the CALPALMY 2-pack. Pick the size that covers the sign or display with the fewest cuts, and check the stated sheet size against the project before ordering, since a 48 by 96 inch sheet needs far more storage and handling room than a 12 by 12 inch panel. More on acrylic sheets 1/2 inch thick sits in the engraving materials section.
Cutting and engraving
Every full-data listing states laser cutting: the SimbaLux sheet also lists tablesaw, jigsaw, drill, router and bandsaw, with clean cut edges without burrs and sharper laser engraving from its cell cast design, while the CALPALMY 24 by 48 sheets list engravers, tablesaw, power saws, electric jigsaw, drill and hand tools, and warn that an acrylic knife cannot be used. The Fab Glass sheet lists laser, table, mitre and hand saw, plus snips and hacksaws, and states it bends with a heat gun and thermoforms. Match the tool list to the tools on hand, and note that the title-only CALPALMY 12 by 12 sheets state no cutting tools at all.
Clarity and weather resistance
The SimbaLux sheet states Grade A clear finish with weather and UV resistance for the sheet itself, not UV protection over an item it covers, while the CALPALMY 24 by 48 sheets state a glass-like finish, weatherproof and UV resistant construction, and resistance to yellowing, cracking and fogging across minus 40 to 190 degrees Fahrenheit. The Fab Glass sheet states exceptional optical quality with an ultra-clear finish on the edges. For outdoor signs and display, weigh the stated weather and UV resistance against the stated clarity, and keep the protective film or paper on until the sheet is installed.
Project Match
- Laser engraved signage: the SimbaLux cell cast sheet, with sharper laser engraving and clean cut edges without burrs, fits signs and display cases.
- Tabletops and shelving: the CALPALMY 24 by 48 2-pack and the Fab Glass 48 by 96 sheet fit larger surfaces, with the Fab Glass sheet covering 32 square feet in one piece.
- Small craft projects: the 12 by 12 inch sheets fit signs, display stands and craft work with the least cutting.
How the scores add up
The HQ Score weighs performance, build, value, safety and warranty. For sheets, safety means stated shatter and impact resistance, scratch and chemical resistance, weather and UV resistance, and protective film or paper where the listing states them. Only one of the four listings states a warranty term. How we pick explains the weights.
| Product | HQ Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| SimbaLux 12×12 | 9.6 | 28 | 21 | 20 | 8 | 3 |
| CALPALMY 24×48 | 9.6 | 30 | 21 | 21 | 7 | 0 |
| Fab Glass 48×96 | 9.6 | 29 | 21 | 20 | 8 | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
FAQ: lasers and CNC
Can you cut acrylic sheets?
