It is necessary to release end faces of sheets from packing and to protect them with the face tape before polycarbonate installation immediately. Thus the end face of sheet turned to a bottom, should be protected with the punched aluminum tape, and the top end face - with continuous aluminum tape (hermetic tape). If the top end face does not contact directly to environment, it is possible to apply an adhesive tape of suitable width instead of a special tape. In case if the top end face will be monolithic, is admissible to refuse application of a continuous tape in general. The bottom end face isn't exposed to be monolithic under no circumstances - it should be mounted openly for maintenance of an effluence of a condensate.
It is recommended to protect the punched tape at the bottom end face structured profiles with the russian “П” or “Г” letters, thus the profile should be mounted so that to provide a free exit of a condensate. (It is recommended to use profiles «Novattro»).
The short side of many face profiles on the sheet should be turned outside as only it has a protective UV-layer. Face profiles «Novattro» have a protective UV-layer on all external surface that gives more possibilities for installation and usage.
