FAQS

Are there special paints to use?

  1. Any paint used must be compatible with polycarbonate and free of solvents which will attack the sheet.
  2. It is highly recommended to check with the supplier of the paint to insure that not only is the paint compatible with polycarbonate but also to verify the nature of the application is conducive with the type of paint being used.

Are there special adhesives to use for bonding 2 sheets together?

  1. Urlane #5774 & Urlane #5776
  2. Weld-On 55
  3. GE RTV108 & Construction 1200
  4. Attach sheets mechanically
  5. Always check with the supplier of these adhesives to insure compatibility with polycarbonate sheets.

Are there special silicones to use?

  1. Any silicone used must be 100% silicone and cannot contain a PVC base.
  2. GE Ultrapruf II SCS2902 or DOW 795
  3. Always check with the silicone manufacturer/supplier to insure their product is compatible with polycarbonate sheets.

What is the Correct Orientation for Flutes?

Exterior Applications – flutes must always run vertical or parallel with the slope. This allows any condensation build up, caused by different surface temperatures on the interior and exterior surfaces, to drain (weep) out of the flutes of the sheet.
Interior Applications – flute direction is not an issue since the sheet surfaces are almost always the same temperature, and condensation should not be an issue.

What are the basic installation steps?

  1. Field verify all dimensions and make sure all panels are trimmed and or cut to size.
  2. Make sure all flutes are clear of dust or debris. The use of high pressure air or shop vac can help with this step.
  3. Tape the exposed ends with our breathable filter tape which prevents further dust, dirt or debris from entering the inside of the sheets.
  4. Remove plain bottom masking from the bottom of the panels and wipe down with an anti-static solution (Novus is an approved provider).
  5. Install profiles and sheets.
  6. Remove printed masking from the top of the panels immediately after install. Wipe down top surface with an anti-static solution.

How important are Do’s and Don’ts?

Don’t walk on sheets, especially when installed.
Do seal sheet ends with solid and vented tape; always – it is a must do. Don’t store sheets in direct sun light. Do call for technical assistance – 800-537-0095. Don’t expose Polygal Sheet to solvents or other chemicals. Do pre drill & pre cut sheets prior to installation, & blow out sheet flutes with high pressure air prior to taping. Don’t use any PVC based material below duromator 80 as PVC will attack polycarbonate.

How are Polygal Bent Sheets Formed?

Polygal Sheets are usually cold formed, and MUST be thermoformed if a radii less than the minimum radii for cold forming is desired. When cold forming Polygal Sheets, the sheets are always bent along the length (direction of flutes) and the length must be greater than sheet width. The minimum cold form radii are shown below.
  • 4.5mm (3/16”) – 2’ 4” (0.71m)
  • 6mm (1/4”) – 3’ 5” (1.05m)
  • 8mm (5/16”) – 4’ 7” (1.40m)
  • 10mm (3/8”) – 5’ 9” (1.75m)
  • 16mm (5/8”) – 9’ 2” (2.79m)
  • 16mmTC – 13’ 0” (3.96m) Triple Clip System
  • 25mm (1”) – 14’ 9” (4.50m)

Do I need specials tools to cut and drill the sheets?

Polygal Sheets can be cut and drilled using standard wood working tools.
  • Cutting – standard circular, jig, or table saw with a blade having 8-12 teeth per inch. Thinner gauges can be cut with a box knife.
  • Drilling – standard wood drill bits. Trimming – standard box cutting knife.
Self Extinguishing – when flame source is removed. Emit – carbon monoxide & carbon dioxide gas when burning (the same as red oak in a fire place).
