Service Temperature |

-4°F to +212°F.

Installation |
MWI
recommends fastening the ridge cap with "one-steppers".
This unique fastener automatically oversizes the hole in
the polycarbonate, which allows for thermal expansion.
Holes must be more than 2" away from the end of the
sheet. Fasteners must be applied so that the washer sits
evenly on the sheet: they must not be overtightened as
this will prevent thermal movement. The polycarbonate
ride cap is 10'6" to allow for 6" end lap

Fire Performance |
The
fire performance of Marlon CS Longlife has been
independently tested and the following classification
obtained:
- ASTM D635-98 NO BURN
|
|
Venting |
| An
important feature of Marlon CS Longlife is that its
softening point is below 390° F. When a fire in a
building is underneath a Marlon CS Longlife sheet it
will soften and allow smoke, heat and gases produced by
the fire to escape. This 'venting' property means that
damage within the building can be reduced. |
