Sunboard (PVC Foam Board): Thickness Guide, Uses and Buying Tips

Posted by



Sunboard is the go-to sheet when you need something very light, easy to print on and resistant to water. It is the most budget-friendly of the three popular sheets, and it works for everything from shop signs to furniture panels. This guide covers thickness, uses and buying tips.

What Is Sunboard?

Sunboard is the Indian trade name for PVC foam board, also called PVC foam sheet. It has a closed-cell foam core and a smooth, matte skin on both faces. That structure makes it stiff for its weight, resistant to moisture and easy to cut, drill and fix.

Maestroglas offers PVC foam boards in several grades. MaestroEco foam boards run from 2 mm to 15 mm, and MaestroHard covers heavier-duty needs across a wider thickness range.

Sunboard Thickness Guide

ThicknessCommon uses
2 mm to 3 mmPrinted posters, lightweight signs, craft projects
4 mm to 5 mmStandees, display boards, shop signage
8 mm to 10 mmExhibition panels, partitions, name boards
12 mm to 15 mmFurniture parts, wall cladding, shelving
15 mm and aboveHeavy-duty fixtures, cabinets, bathroom panels

As a rule, pick a thicker board for larger spans or any piece that must carry weight or hold screws.

Top Uses for Sunboard

  • Advertising panels: direct print or vinyl-mounted signs
  • Exhibitions and events: stall walls, backdrops and standees
  • Interior signage: name boards, directional signs and wall graphics
  • Furniture and interiors: cabinets, partitions, bathroom and kitchen panels
  • DIY and education: models, school projects and craft work

Why People Choose Sunboard

  • Light weight: easy to carry, hang and install
  • Water resistance: suits damp areas where wood-based boards swell
  • Printable surface: takes digital print, vinyl, paint and lamination
  • Easy to work: cuts with a knife, saw or router and holds screws and adhesive
  • Value: costs less than acrylic for most opaque applications

Printing and Fabricating Sunboard

  1. Clean the surface with a dry cloth before printing or sticking vinyl.
  2. Use a sharp blade for thin boards and a fine-tooth saw or router for thick ones.
  3. Seal the edges with paint or edge tape for a neat finish on visible sides.
  4. Glue with PVC-friendly adhesive and clamp lightly while it sets.
  5. Pre-drill screw holes in thicker boards to prevent splitting.

Buying Tips

  • Tell the supplier your use and span so the right thickness is recommended.
  • Check that the surface is smooth and even for clean printing.
  • Choose a higher density grade for furniture or screw-fixed parts.
  • Ask for a sample before a large order.
  • Compare grade and thickness, not just price per sheet, since lighter boards are not all alike.

Frequently Asked Questions

Is sunboard waterproof? Sunboard is water and moisture resistant and does not swell like wood-based boards, which is why it suits bathrooms and kitchens.

Can I print directly on sunboard? Yes. Its smooth surface works well with digital printing and vinyl.

Is sunboard suitable for outdoor use? It can work outdoors for short to medium periods, but long-term sun exposure may fade or warp it. Use acrylic for permanent outdoor signs.
