e) Specialized Systems for Polycarbonate Glazing:
Particularly designated profile systems for use with solid
polycarbonate glazing are produced by (or for) contractors
specializing in polycarbonate glazed structures. These series offer
deeper rabbet depth and are produced in heavy gauge suitable
for the thickest PALSUN sheet and relatively heavy loads, intended
for specially shaped, high-end public & office buildings. Such
profiles are not freely available for purchase, and could be
acquired only as parts of complete projects. Such profiles are
usually more elaborate and may offer additional properties as
external condensed vapor drainage systems for skylights as well as
internal channeling solutions for rainwater infiltration.
Profile illustrated on Fig. 27 can be used either as vertical post or as
overhead skylight support girder, as it has internal channeling for
infiltrated rainwater.
Profiles fitted with external condensation water drainage systems are more suitable & efficient for
overhead skylights, as they provide extra protection from cold drippings from above.
Any of these options would require specific
accessories like designated EPDM glazing profiles of
specific shapes to fit the intended purposes and
profile, along with the more common compatible
silicone sealant, self-adhesive sealing & spacing strips
etc. required for these types of structures.
