APPROVED COATED-SURFACE DETECTION METHODS
2.1 Detection of the coated surface is a critical step in correctly processing SunGuard Solar, High
Performance, SuperNeutral, and ClimaGuard Neutral 70 / Green 70 coated glass products.
The user must establish which surface has been coated:
When opening incoming packaging (packing tags will indicate the orientation of the
coated surface within the packaging; however, formal detection using one of the methods
outlined below is necessary)
When moving material
Before any subsequent processing of the glass
2.2 Common Methods Available for Detection
2.2.1 Commercial Coating Detector (Figure 1)
A coating detector that does not utilize metal contacts must be used. Metal contacts can
scratch the coating if applied to the coating surface.
Detectors, such as the one pictured, can be obtained from EDTM, Inc.®, in Toledo, OH, via
their Web site (www.edtm.com). Detectors are also available from MLM Enterprises in
Walbridge, OH, via their Web site (www.mlmenterprisesinc.com).
Figure 1. Commercial Coating Detector
2.2.2 Ohm Meter Detector
PROCESSOR
USER’S GUIDE
COMMERCIAL
Set an ohmmeter on a high-resistance setting (e.g., Rx 10,000).
Contact the glass surface (near the extreme edge only) with the positive and negative
terminals approximately 25 mm (1 in.) apart.
A meter reading registers if the terminals are contacting the coated surface.
No reading registers if they are contacting the uncoated surface.
When using this method, take care to avoid scratching the coated surface.

2.3 Sputter-coated films do not have the surface roughness of pyrolytic films and cannot easily
be felt. Touching the coated surface with bare hands or with gloves is not a reliable method
for detecting the coated surface. Skin oils are difficult to remove and can damage the coated
surface after prolonged exposure.
2.4 SunGuard SuperNeutral HT coated products are supplied with Temporary Protective Film
(TPF) on the coated surface. TPF is discussed in detail in Section 3.

TEMPORARY PROTECTIVE FILM (TPF) — SUNGUARD HT ONLY
3.1 For SunGuard SuperNeutral Heat Treatable products, Guardian has implemented a fullsurface protective film, designated “Temporary Protective Film” (TPF). TPF increases
fabrication yields while stabilizing the coated surface during storage.
TPF is a full-coverage, recyclable, polyethylene (PE) tape applied to heat-treatable doublesilver coatings.
TPF is applied directly to the coated surface by Guardian during the manufacturing
process.
The adhesive used in conjunction with the TPF is low tack and leaves no residue on the
coated surface, resulting in the cleanest, pre-furnace condition possible.
3.2 TPF is applied to the coated surface. The product must be cut, seamed, and washed with
the coated (TPF) side up.
3.3 TPF must remain on the surface of the glass during all fabrication steps prior to the furnace.
Figure 3. TPF Instructions
3.4 Follow the TPF removal instructions below. Do not attempt to start the removal of the TPF
with bare hands or gloves.
PROCESSOR
USER’S GUIDE
COMMERCIAL
EDITION 1.0
Jenuary 2009
Use double-sided tape and/or a tacky roller to start the removal process.
Start at the corner of the lite and lift towards the center of the glass.
Once the edge of the film is a safe distance of 50–76 mm (2–3 in.) from the surface,
removal by hand may be performed, provided that there is no direct contact with the
surface of the glass.
3.5 TPF must be removed prior to placing the glass the furnace.
3.6 For more information on TPF, please consult Guardian’s Product Application Note,

PROPER FABRICATION TECHNIQUES
5.1 The coated surface must always face up (away from conveyor rolls, felt covers or roller balls)
during fabrication to avoid the possibility of glass splinters and chips scratching the glass
surface. Refer to Section 2, “APPROVED COATED-SURFACE DETECTION METHODS,” in this
User’s Guide for more information.
5.2 Contact with the coated surface must be avoided during fabrication. Contact must be made
from the edges or with the uncoated surface of the lite as shown below. Never palm coated
glass.
Figure 4. Handling Coated Glass
5.3 The coating must not be handled with bare hands. Clean, dry gloves must be worn when
handling SunGuard Solar, High Performance, SuperNeutral, and ClimaGuard Neutral 70 /
Green 70 coated glass products.
5.4 Sharp objects, such as nails, screws, razor blades, steel wool, etc., can scratch and damage
the coating and must not be used on coated products.
5.5 Blades or other scrapers must never be used to scrape material off the coated surface, as
these may damage the coating and the glass.
5.6 The glass must be removed from the container such a way that cated surface facing up on
the table. Care must be taken to avoid sliding or rubbing one pane of glass against another.
5.7 If suction cup equipment is utilized, it must be properly maintained for pressure and

If suction cups must contact the coated surface during movement of the individual lites,
they must be clean and dry.
The minimum number of suction cups must be used to safely move the product.
If suction cup frames are used to move and position lites on a tilt table, the drop height
must be minimized to eliminate any sliding of the cups against glass. All glass must be
aligned so as to have no more than a +6 mm (1/4 in.) difference between the edge of the
glass and the drop table.
5.8 All Guardian product tags must remain with the original packaging. Lites must always remain
traceable to original Guardian case tags.
5.9 SunGuard Solar, High Performance, SuperNeutral, and ClimaGuard Neutral 70 / Green 70
coated glass products must be washed immediately after any edge grinding, polishing,
seaming or other fabrication steps.
8
www.SunGuardGlass.com
5.10 If lubricants or coolants are used in processing, the resulting glass grit slurry may become
highly alkaline (with a pH of 8.0 or higher) and will damage the glass and coating if not
removed promptly.
5.11 Glass must be placed on racks for movement to the next process after cutting. The
preferred method of separation is foam-covered cork tabs with the static foam side
contacting the coated surface or with polyfoam strips/sheets.
If A-Frames are used, like sizes must be stacked together.
Different sizes must be separated by foam tabs or polyfoam strips (see Section 10,
“INTERLEAVING MATERIALS,” in this User’s Guide for more information on glass
separation when transporting).
Harp racks present a scratch hazard to the SunGuard coatings and are not
recommended. If the processor chooses to use harp racks, the following actions are
recommended:
– Keep harp racks clean and well maintained.
– Avoid sliding the coated surface against the harp cords.
– Never put more than one lite in a slot.

9.16 The set-point temperature of the furnace must be at or below 700°C (1290°F).
9.17 Because of the thermal-reflective properties of SunGuard Solar, High Performance,
SuperNeutral, and ClimaGuard Neutral 70 / Green 70 coated glass products, adjustments
to the furnace profile and conveyor speed will be necessary in heat-treating processes. As
a general rule:
Furnace temperatures must be decreased.
Furnace residence time must be increased.
Each of the above must be adjusted in direct proportion to the improvement in reflective
properties of the glass being heat treated.
9.18 The thermal-reflective properties of SunGuard Solar, High Performance, SuperNeutral,
and ClimaGuard Neutral 70 / Green 70 coated glass products will render top-mounted
measuring devices inaccurate.
Adjustments to the emissivity settings of top-mounted radiant pyrometers will be required.
Even with correct adjustments, top-mounted pyrometers can be inaccurate.
Surface temperatures are best measured from the bottom (uncoated side) of the
product.
9.19 After heat treating, the coated lites must be separated using interleaving. The preferred
method is to use foam covered cork tabs with the static foam side contacting the coated
surface (see Section 10, “INTERLEAVING MATERIALS,” in this User’s Guide for more
information on glass separation when transporting).
9.20 Heat-treated SunGuard Solar, High Performance, and SuperNeutral coated glass products
must not be re-heat treated after the initial heat treatment.
9.21 Glass temperature must be less than 50°C (120°F) prior to packing.
9.22 A visual inspection of both transmission and reflection of heat-treated glass must be
performed regularly and in accordance with Guardian quality standards. Refer to Section

INSULATING
12.1 Many processors have vertical insulating lines that tend to reduce deflection on standard
insulated glass. However, processors with horizontal insulating lines should be extremely
cautious regarding potential glass deflection. During horizontal glass insulation, the
unsupported upper lite can sag under its own weight, creating a concave effect in the
unit. The resulting deflection creates an observable concave or collapsed appearance on
the unit’s exterior. The amount of deflection is solely a function of the horizontal insulating
process and the weight of the glass. In fact, this appearance has been cause for rejection
on project sites.
12.2 The deflection is caused by a combination of the shape, size, weight and thickness of glass.
As an example, a horizontal insulating process involving a 2 meters x 2 meters (4 m²)
square unit could produce a 8-10 mm deflection in the center. However, a rectangular unit
of the same area (e.g., 1 meter X 4 meters) may exhibit no deflection. Aspect ratio is critical;
squares will always be at greater risk than rectangles. As an interim guideline, Guardian
recommends that the insulation crew measure deflection on square units and on any unit
greater than 4 meters².
12.3 The concave appearance may be reduced by placing the unit’s #1 surface against a solid
base for support during sealant application. Deflection is easily measured by attaching
string diagonally from opposing corners. The deflection should be measured where the
two strings intersect. Units exhibiting any measurable gap between the string intersection
and glass surface should not be shipped if any optical distortion is visibly apparent.
12.4Special care must be taken when using the Truseal, Duraseal or Duralite spacer system for
commercial insulated glass unit fabrication. Truseal has placed restrictions on the physical
size of the unit. The processor is responsible with complying with Truseal’s requirements
for insulated glass unit fabrication. Insulated glass units fabricated with the Truseal family
of flexible spacer systems require the application of a secondary seal. Please contact your
local Truseal representative or distributor for up-to-date information on product usage.
12.5 Quality control is a processor responsibility. The processor must ensure that the
performance and optical requirements of the project can be met with the available
capabilities at the factory.
12.6Guardian recommends that inspection for deflection be added to the insulator’s daily quality
routine. As a final check, representative units should be spot checked outdoors to confirm
acceptable optics.
12.7 For assistance with center-of-glass deflection, please contact your Sales Manager or
Technical Services Executive.
12.8 The coated surface must always face up (away from conveyor rolls, felt covers or roller
balls) during insulating to avoid the possibility of glass splinters and chips scratching
the glass surface. Refer to Section 2, “APPROVED COATED-SURFACE DETECTION
