1/2" Clear Extruded Acrylic Sheet - 48" x 96"

Maximum-duty acrylic for specialized applications requiring extreme thickness and exceptional structural performance. At 1/2" thick, this extruded acrylic sheet represents the upper limit of standard sheet availability, delivering unmatched rigidity, crystal-clear transparency with 92% light transmission, and the substantial material presence required for large aquarium installations, architectural glazing, and specialty display applications. When specifications demand absolute maximum acrylic material, 1/2" delivers performance that standard thicknesses cannot match. Manufactured by Optix® (Plaskolite), the trusted name in premium acrylic.
Thickness: 1/2" (0.472") Size: 48" x 96" Weight: ~94 lbs Material: Extruded Acrylic (Plexiglass)

Why Choose 1/2" Clear Acrylic at Full Sheet Size?

Why Choose 1/2" Clear Acrylic at Full Sheet Size?

The 1/2" thickness represents maximum-duty acrylic for applications that cannot be satisfied with thinner materials. This extreme sheet delivers exceptional structural mass for the longest possible unsupported spans, handles significant water pressure for large aquarium viewing panels, and provides the substantial material thickness required for architectural installations demanding both maximum rigidity and superior optical clarity. At approximately 94 pounds per full sheet, this is serious material for specialized applications where engineering specifications or design requirements mandate absolute maximum acrylic thickness.

With 92% light transmission—superior to polycarbonate's 88%—this thickness maintains acrylic's renowned optical clarity advantage while delivering structural performance that approaches thicker polycarbonate in rigidity under static loads. The full 48" x 96" size enables large-scale installations for major aquarium projects, architectural feature walls, and commercial display applications where crystal-clear transparency and extreme material presence both matter. When design specifications require the confidence of maximum available acrylic, when aquarium installations demand substantial pressure-resistant panels, or when architectural projects need unmatched clarity with maximum structural capacity, 1/2" acrylic delivers.

This Thickness Excels When You Need:

  • Maximum acrylic structural capacity - Exceptional deflection resistance for extra-long unsupported spans exceeding 72 inches or extreme-load applications requiring absolute maximum acrylic rigidity
  • Large aquarium water pressure resistance - Substantial thickness required for major aquarium viewing panels, water features, and marine display installations where material must withstand significant hydrostatic pressure
  • Architectural statement installations - Maximum material presence for feature walls, artistic installations, and architectural elements where substantial thickness adds visual impact alongside structural performance
  • Unmatched optical clarity with maximum thickness - 92% light transmission in maximum available acrylic thickness for applications requiring both superior transparency and extreme structural capacity
  • Specialty engineering requirements - Meets demanding specifications for applications where calculations indicate standard acrylic thicknesses provide insufficient capacity for safety factors or performance requirements

Trusted Manufacturing Quality

Our clear extruded acrylic sheets are manufactured by Optix®, a premium brand from Plaskolite—one of North America's leading acrylic producers. Optix® acrylic meets ASTM D4802 standards for extruded acrylic sheet, ensuring consistent quality, optical clarity, and performance. Extruded acrylic offers excellent dimensional stability and superior optical properties, making it the professional choice for specialty applications requiring maximum material thickness with exceptional clarity.

When to Choose 1/2" Acrylic Over Other Thicknesses

Select 1/2" acrylic when engineering specifications explicitly require maximum available acrylic thickness, when you're constructing large aquarium viewing panels requiring substantial water pressure resistance, or when architectural installations demand extreme material presence with superior optical clarity. This thickness is also specified for specialty display applications requiring maximum structural capacity, large-format artistic installations needing substantial material, and any application where absolute maximum acrylic delivers necessary performance that standard thicknesses cannot provide.

For most architectural glazing, display applications, and protective installations, 1/4" or 3/8" acrylic provides adequate performance at substantially lower cost and weight. However, when specifications mandate maximum acrylic material, when aquarium applications require extreme pressure resistance, or when architectural designs demand the visual and structural impact of maximum thickness with crystal-clear transparency, 1/2" delivers unmatched performance. This is specialty material for applications where standard thickness is genuinely insufficient and optical clarity remains paramount.

Technical Specifications - 1/2" Extruded Acrylic

Technical Specifications - 1/2" Extruded Acrylic

Nominal Thickness 1/2" (0.472" actual)
Sheet Dimensions 48" x 96" (full sheet)
Approximate Weight 94 lbs per sheet
Light Transmission 92% (crystal clear)
Impact Strength 17 times stronger than glass (not suitable for high-impact applications)
Temperature Range -40°F to 180°F continuous
Material Type Extruded Acrylic (PMMA - Polymethyl Methacrylate)
Manufacturing Brand Optix® by Plaskolite
Material Standard Meets ASTM D4802 for extruded acrylic sheet
Surface Finish Gloss on both sides with protective masking
Recommended Span 72+ inches unsupported (application dependent), 90+ inches with frame support
Scratch Resistance Superior to polycarbonate (harder surface)
UV Resistance Good outdoor weathering (will yellow less than polycarbonate over time)
Flammability UL 94 HB rating (burns when ignited, not self-extinguishing)

Note on Impact Resistance: While acrylic is 17 times stronger than glass, it is significantly less impact-resistant than polycarbonate (which is 250 times stronger than glass). For high-impact applications, protective barriers in high-traffic areas, or outdoor installations subject to abuse, we recommend polycarbonate sheets instead. Acrylic excels in applications where optical clarity, scratch resistance, and structural rigidity under static loads are priorities.

Note on Outdoor Use: Acrylic has excellent UV resistance and weathers better outdoors than polycarbonate, resisting yellowing for 10+ years. However, its lower impact resistance makes it unsuitable for applications where vandalism, hail, or impact damage are concerns. For protected outdoor applications and architectural installations with minimal impact risk, 1/2" acrylic performs excellently.

Note on Aquarium Applications: For aquarium viewing panels and water features, consult engineering guidelines for proper thickness based on water depth and panel dimensions. Professional aquarium builders typically use specialized calculations to ensure adequate safety factors for hydrostatic pressure loads. The 1/2" thickness is specified for larger aquarium installations where substantial water pressure requires maximum acrylic material.

All sheets ship with protective masking on both sides to prevent scratches during fabrication and installation. Remove masking after installation is complete.
