Installation
Guidelines
Marlon FS can be installed in most types of frames including PVC,
wood, steel and aluminium. The framing system must retain the sheet
but allow thermal movement. Only compatible sealants must be used,
these include silicone, EPDM, neoprene or 'plasticiser free' chloroprene
materials of proven performance. Please note that PVC gaskets are
not compatible with polycarbonate.

| Cutting
marlon
fs
is easy to saw and cut on standard workshop equipment. It can be
machined on conventional milling machines with standard high speed
tools. Notches adversely affect the mechanical properties of polycarbonate
and should be avoided.
Drilling
Any commercially available metal drill without a specially ground
bit is suitable for use with marlon
Fs

The following
point should be observed when drilling MARLON FS:
· Do not use cutting oils
· The sheet may break as a result of notching
· Fixing threads should only be used if there is no alternative
· The hole should be at least 1.5 x hole diameter from the
edge of the sheet.
Thermoforming
The parameters for thermoforming will vary depending on the equipment
being used. This information is for advice only. Experimentation will
usually be necessary in order to achieve the best results from a particular
thermoforming setup.
Thermoforming will reduce outdoor weather performance of UV protected
material. Consequently it is essential to have a well controlled and
minimised heating time and to avoid excessive stretching, due to heating
or mould design. In practice some experimentation is required for
the individual thermoformer to find his optimum conditions.
Protective film should be removed before pre-drying or any thermoforming
process, as otherwise it will adhere very strongly to the surface.
Line Bending
1. For line bending pre-drying is not normally required.
2. A recommended temperature between 155°C and 165°C.
3. The width of heated material must be approximately five
times the sheet thickness.
4. Up to and including 4 mm thick can be bent when heated from
one side only.
5. Over 4 mm it is necessary to heat from both sides.
6. Bending sharp internal corners should be avoided. Use a
former radius at least equal to the sheet thickness.
