- Size
Limitations:
Southwall Technologies'
wavelength-selective film has a coating width of 72 inches and, as a
result, Heat Mirror units must have one dimension which is 72 inches or
less. Unit lengths can be as long as 175 inches.
- Breather
Tube Instructions:
Some Heat Mirror units are equipped with
pressure equalizing breather tubes. DO NOT
TWIST, PULL OR CUT this
tube or pull out from unit. This breather tube must be
completely closed upon arrival by crimping twice with pliers.
If possible, units should be installed with the breather tube in an
upper corner position, pointing downward.
- Flush
or Structural Glazing:
In the event that the project dictates the
use of butt-glazed or structurally-glazed product,
this must be disclosed and written into the specification prior to
the project bid. Heat
Mirror fabricators must be apprised of this condition in
advance of quoting or fabrication.
- Polyurethane-Sealed
Units:
Standard Heat Mirror units are fabricated
with a polyurethane sealant which must not be exposed to
sunlight. The glass unit edge, spacers, and
sealant must be completely covered (captured) by the framing system
(9/16" minimum sight line coverage). These organically-sealed
units DO NOT lend themselves to two-sided or
structurally-glazed applications.
- Glazing
Materials:
Heat Mirror insulating glass units must be
installed with glazing materials and sealants compatible with
PRC-DeSoto PRC 4429HM polyurethane sealant, or with Dow CorningT 3-0117
silicone insulating glass sealant. It is the glazier/installer's
responsibility to verify framing design compliance and glazing material
compatibility prior to installation. For compatibility information
please call Alpen Energy Group.
- Heat Mirror Transparent Film:
The exterior side of each Heat Mirror unit is
clearly marked, and must be glazed accordingly to maintain warranty
coverage.
- Storage
Requirements:
Heat Mirror insulating glass units should be
installed promptly. If required, storage facilities must
be at moderate temperature, dry, and covered. Breather tubes must
be closed upon arrival. Units must
be covered or shielded from sunlight exposure.
GENERAL GLAZING INSTRUCTIONS:
|
(1) Glazing Materials:
Neoprene gaskets or non-hardening, non-corrosive glazing tapes or
sealants must be applied in such manner as to effect and maintain a
watertight, weatherproof seal for a period of time equal to the Heat
Mirror warranty. All glazing materials must be compatible
with polyurethane for Heat Mirror units sealed with this material.
|
(4) Weep (Condensate) System:
Insulating glass units must not be exposed to moisture accumulation or
high humidity dew points. The glazing system design and
installation must provide a positive weather seal and unobstructed weep
drainage.
|
|
(2) Setting Blocks: Neoprene
or silicone blocks must be placed at unit "quarter points" and equally
support insulating glass unit inner and outer lites. Setting
blocks should be 4" to 6" long and 1/8" wider than the thickness of the
unit as indicated in the GANA Glazing Manual.
|
(5) Sight Line Coverage (Bite):
Frame and gasket materials must provide a least 9/16" sight line
coverage (bite). Insulating glass sealants and spacers must
be completely covered by the framing system.
|
|
(3) Edge Clearance:
Unit must be centered in the opening so that minimum spacing (1/4")
exists between edge of glass and frame (1/8" on small units).
No wood or metal shall contact the glass at any point in the
frame. Face and edge clearances shall comply with GANA
Glazing Manual, Chapter IX minimum recommendations.
|
(6) Framing: Openings
must be square, in plane, and free of obstructions. Sash and
frames must be structurally adequate to support weight of unit and
prevent twisting stresses. Frame deflection must not exceed
L/175 or less, depending upon size (AAMA).
