Determination of Required Sheet Dimensions
The information below is presented to assist in ordering the required dimensions.
Determination of Thickness
In order to determine the required thickness, the following table lists the sheet thickness required for a given wind load and width
(at the narrow side of the sheet).
Wind Load - Pa* or N/m (psi)
400 (0.06) 800 (0.12) 1200 (0.17) 1600 (0.23) 2000 (0.29)

1000 (39) 5 (0.20) 6 (0.24) 8 (0.31) 8 (0.31) 10 (0.39)
1200 (47) 6 (0.24) 8 (0.31) 8 (0.31) 10 (0.39) 10 (0.39)
1400 (55) 8 (0.31) 10 (0.39) 10 (0.39) 12 (0.47) 12 (0.47)
1600 (63) 8 (0.31) 10 (0.39) 12 (0.47) 12 (0.47) NS**
1800 (71) 10 (0.39) 12 (0.47) 12 (0.47) NS** NS**
2000 (79) 10 (0.39) 12 (0.47) NS** NS** NS**
* For wind load in kg/m, multiply value by 0.1 (e.g. 400 N/m = 40 kg/m)
** NS - Required thickness exceeds largest available standard thickness (12mm or 0.47in.).
Example:
If the wind load is 800 N/m and the width of the sheet is 1200mm, a sheet of 8mm thickness should be used.
But if for the same wind-load the width of the sheet is 1600mm, a sheet of 10mm thickness should be used.
Determination of Sheet Size
Due to thermal expansion, PALSUN & PALTUF sheets have to be cut accurately at predetermined lengths smaller than the
dimensions of the frame. At the end of the frame, clearance must be left for expansion. The tables and diagram on the next page
explain how to calculate the required sheet dimension. In addition, there is a table showing the expansion clearance necessary for
various sizes of PALSUN & PALTUF sheets.
Installation
Choice of the Frame
PALSUN & PALTUF sheets can be mounted in most existing frames made of wood, rigid PVC, aluminum or other metals. It is recom-
mended to use neoprene or EPDM packing (never use soft PVC) to secure the sheet in its frame, rather than xing with screws.
Butyl rubber sealing strip or silicone sealant (PALRAM has tested and recommends Dow Corning Q3-7098 or Q3-3793 and Novasil
S 64) are also permissible. A list of compatible adhesives and sealants appears on the leaet, “Adhesives and Sealants Compatible
with Polycarbonate Sheets”.
