VEROLITE™

POLYCARBONATE TWINWALL SHEETING

PAGE THREE

Easy Instructions
1. Always install the sheet with the flutes oriented vertically. When used as a roof covering, design with at least a 5º slope, never horizontal.

2. Remember to allow for expansion and contraction in every installation. Bronze and grey panels change more in size. Use extrusions that allow for sufficent edge engagement plus the expansion allowance.

3. Panels can be cut with protective masking in place with a fine tooth saw or sharp knife. Remember to remove the masking prior to final fixing in place. Chips from cutting should be blown out of the flutes.

4. The specialy treated weather side is identified on the masking. This side must always face the exterior.

5. In vertical installations, the top flutes should be capped with an extrusion or tape and the bottom left open for drainage.

There are many aluminum and polycarbonate glazing systems available for use with Verolite. Polycarbonate extrusions are made from the same material as the Verolite sheets. They are available in several profiles including end caps and joining "H" shapes. Also available is a two-piece joining extrusion which consists of a base, which is fastened to the frame and a cap which snaps into place to hold the sheets. These profiles are non - structural and depend on the frame of the structure for support.

Sealants
Use silicone sealants compatible with polycarbonates such as:

#999-A with 1205 Primer,
Dow Corning Corp.,
Mississauga,Ont. & Midland Mich.

Silglaze N Gesil N,
General Electric Co., Waterford, NY. (Always check compatibility to polycarbonates before using elastomeric adhesive and soft gaskets for dry installation system.)
