PALSUN® PALGARD™
Glazing Guide

Notes for Tables 11 & 11a:
1. PALSUN glazing sheets should be installed with their curved edges sustained on the supporting arches, with
15 to 25mm ( 5 /
8
”-1”) edge engagement, depends on span, plus 2-3mm ( 3 /
32
”- 1/8”) thermal expansion gap.
2. Thin sheets (up to 6mm or ¼”) could be bent as relatively short glazing panels, 2.00 to 3.00m at 1000-1220mm
width (6’7” to10’ length, at 40” to 48” width). Thick sheets of 8mm (5/16”) and up could be cold curved only as
special order long panels (4.00 to 7.00m or 13’2” to 23’ long) particularly when installed in full 2050mm (6’9”)
width or close.
3. Supporting arches & clamps should withstand total maximum permitted loads without difficulty.
4. Spans less than 500mm (20”) are generally impractical for such installation method.
5. Lowest radius value depicted is minimal permitted radius for that specific PALSUN sheet.
6. Depicted spans are suitable for most common stationary structures, under pressure or uplift loads . Special
structures, like mobile pool covers, may use wider spans, subject to preceding approval.
