INSTALLATION INSTRUCTIONS, DIRECTIVES & RECOMMENDATIONS
CLARIFICATION: Wherever PALSUN is mentioned - PALGARD is included, unless noted otherwise.
1. Flat PALSUN® & PALGARD™ Glazing Installation on Supporting Frames.
Supporting Methods & Appropriate Load Tables:
a. PALSUN glazing should be installed, similarly to glass, in or on a supporting framework, on which the
glazing would be supported on all its edges (4 sides clamped), on 3 sides or on two long edges (2 sides
clamped), with or without a glazing groove, and clamped to that frame with glazing bars or profiles.
b. PALSUN glazing could be installed, similarly to glass, in the “wet” or “dry” methods:
Basic installation procedures follow. Other variations of said methods are also used.
1) “WET” METHOD: A compatible polymeric putty is applied along the window sash, on all its perimeter
as a base for laying the PALSUN glazing, exactly like it is done in “wet” glass installation.. Then the glazing
is laid in place, leaving enough thermal expansion gaps around it. Glazing bars are then covered with
same putty and installed on the perimeter, fastened to the window frame, clamping the glazing. Finally,
compatible elastomeric sealing compound, (like silicone) is applied all around, inside and out, to assure
window’s impermeability.
Alternate version of that method uses “dry” rubber strips or spacers instead of putty, both in the sash and
on the glazing bar, as base layers, with final silicone application around glazing edges.
“Wet” method is used in wood or metal frames, in regular windows or on heavy-duty framing such as
sound barriers. The method is now less popular, and the “dry” method gets to be preferred.
