Greenhouse Installation Guide
Drilling
1. Drilling should be carried out with a drill bit intended for metal. The hole
diameter must be 4 mm larger than the diameter of the screw to be used.
It is important to support the sheet in the vicinity where the sheet is being
drilled. The dust generated by drilling must be cleared away before the
insertion of the screw.
2. Special attention should be given to drill all the required holes perpendicular
to the face of the material.
Sealing
1. Compatible silicone sealants recommended for use with
Palram polycarbonate sheets:
Manufacturer Sealant
Soudal MS Clear
Bison Polymax
For information on alternatives, please consult your Palram
distributor.
2. Shaped foamed Polyethylene closure strip should be
used to prevent the entry of water, wind, insects or other
small animals between installed sheets. A seal between
the sheet and the edge purlin of the roof can be created
using a sealing strip in the form of the profile. It is held in
place by the same screw used to fasten the sheet to the
purlin. The sealing strip should be manufactured from
cross-linked polyethylene foam (XPE).

Chemical Resistance - Compatible Sealants and Adhesives
1. SUNTUF Plus sheets are resistant to a variety of chemicals and exhibit limited resistance to a second group of chemicals.
A third group of chemicals will attack and cause damage to the sheet. The degree of damage will depend on the severity
of attack and time of exposure.
2. Choose only sealants and adhesives which are compatible with SUNTUF Plus (see paragraph G) .
3. Beware of installing the sheets on wet paint, or other incompatible materials, which may damage the polycarbonate
sheets.
4. Use of sealants or adhesives not included in the recommended list must receive the Manufacturer’s explicit
approval. This can be obtained through your distributor. Use of materials not on the list, or which have not received
the Manufacturer’s explicit approval, may harm the sheet and will void all warranties and any responsibility of the
manufacturer for the performance of SUNTUF Plus.
5. Your local distributor can provide additional information and forward materials for evaluation of their comparability with
SUNTUF Plus.
