ClimaGuard Neutral 70 delivers energy efficiency, color neutrality, and, for busy fabricators, is extremely versatile.

3 ClimaGuard neutral 70 Handling and Fabrication Guide ClimaGuard Neutral 70 is a durable, neutral colour low-emissivity coating that is intended for use in insulated or laminated glass applications. This guideline is intended for the proper handling and fabrication of ClimaGuard Neutral 70 glass. Storage and unpacking GUARDIAN recommends that glass be unloaded under dry, indoor conditions. If outdoor unloading is required, care should be taken to avoid exposure to rain and snow, and glass should be moved indoors as soon as possible. Do not mark the coated surface with adhesive labels or wax crayons and do not drag suction cups or metal objects across the surface. The coating is resistant to damage by such materials, but handling practices that are more aggressive than those used with uncoated glass must be avoided. Case tags should remain with the original packaging and case tag numbers should be traceable to workin-process, and finished goods. Although the coated surface of ClimaGuard Neutral 70 is resistant to staining and chemical degradation, GUARDIAN s customer assumes responsibility for as-coated inventory that is held beyond 12 months from the original date of receipt from GUARDIAN. ClimaGuard Neutral 70 should be insulated or laminated within 2 days of heat-treatment. Surface identification When opening incoming packaging, the packing tags will indicate the orientation of the coated surface; however, formal detection using an approved detection method is required. GUARDIAN recommends using a coating detector. coated side uncoated side Inspection ClimaGuard Neutral 70 can be inspected, in reflection, for uniformity of coating by placing it in front of a black, nonreflective background with a diffuse light source located above or behind the inspector. This simulates the viewing condition where a person outside looks at the daytime reflection of an overcast sky in the Low-E residential glazing. Inspections should also be performed in transmitted light by placing the glass in front of a white, non-reflective background with a diffuse light source located behind the glass (light board). This simulates daytime viewing of the glass from the outside looking through the glass with white interior blinds or drapes. Cutting ClimaGuard Neutral 70 should be cut with the coating side up to minimize the risk of scratching or marking of the coating. Cutting wheel pressures will be very similar to those for uncoated glass. When the glass is moved across rollers or over an air-float table, the coated surface should face up to avoid abrasion or rub marks. Special care is advised when metal tape measures, straight edges or cutting bars come into contact with the coated surface, as abrasion or marking may occur. Multi-lite stacking should also be avoided to minimize abrasion or marking of the coated surface. The coating is resistant to damage, but handling practices that are more aggressive than those used with uncoated glass must be avoided. Edge preparation such as seaming or polishing should be done coated side up, as the rotation of the seaming table casters could cause a swirling pattern where the caster touches the coating if it were facing down. correct handling incorrect handling

4 Washing As with uncoated glass, automatic washing machines using warm water and detergents can be used with ClimaGuard Neutral 70. To avoid abrasion or marking of the coated surface, GUARDIAN recommends that coated products should be washed with the coated surface facing up. When spot cleaning is required, use mild, fast-drying household glass cleaners with a clean, soft cloth. GUARDIAN recommends maintaining detergent wash water tank temperature between C ( F) during operation. Razor blades and steel wool must not be used on the Low-E coated surface. Heat-Treating ClimaGuard Neutral 70 is a single-product solution for annealed and heat-treated applications; as such, there is no separate heat-treatable (HT) version of this product. As with all Low-E glasses, the coating will reflect some radiant heat and so it will require a somewhat longer furnace cycle to achieve the same uniform temperature as uncoated glass of the same thickness. ClimaGuard Neutral 70 must be heat treated with the coated side up to minimize the risk of scratching or marking of the coating. In testing, ClimaGuard Neutral 70 was successfully heat-treated at furnace settings and cycle times similar to pyrolytic coated Low-E glass. Insulating Glass ClimaGuard Neutral 70 is intended for use in insulating glass units, with the coated surface facing the air space. The coating may be placed on either the number 2 surface or the number 3 surface depending on the application requirements. ClimaGuard Neutral 70 should not be used in monolithic or non-sealed applications. It is important to confirm that the glass is effectively cleaned and that full sealant adhesion is developed to the coated surface. ClimaGuard Neutral 70 Low-E has been tested, and found compatible, for IG construction, without edge deletion, with a variety of Hot Melt Butyls, Polyisobutylenes, Polysulphides, Urethanes and One and Two Part Silicones. Please contact GUARDIAN to confirm sealant compatibility or for any questions. Laminating ClimaGuard Neutral 70 may be used in embedded (facing the PVB) or exposed (facing the airspace) laminated applications. ClimaGuard Neutral 70 may only be laminated with an exposed coated surface if the final glazing package will be an insulating glass unit with the coated surface facing the air space. The ClimaGuard Neutral 70 coating is not damaged by normal laminating processes. Care should be taken to minimize excess PVB remaining around the edge of the glass prior to autoclaving, as this can be difficult to remove from the coated surface. Do not use razor blades or steel wool to remove deposits from the coated surface. Edge deletion of the coated surface is not required for embedded or exposed laminated configurations of ClimaGuard Neutral 70 that incorporate approved sealant materials. Impact testing on laminated glass should be performed to ensure compliance with safety glazing requirements. Packing When packing ClimaGuard Neutral 70 coated glass for shipping with the coating exposed, it is preferable to use a slot-racking system that prevents glass-to-glass contact. It is acceptable to stack individual lites of ClimaGuard Neutral 70; however, care should be taken to ensure proper interleaving is used to minimize the potential for abrasion to the coated and uncoated surfaces.

5 Hot weather or cold weather? ClimaGuard neutral 70 is the answer ClimaGuard Neutral 70 helps you save money and makes your home or office a more comfortable place to live or work. ClimaGuard Neutral 70 will provide the following benefits over traditional double or single glazed windows. Cold Weather Climates On a winter s day the temperature outside may be 0 C, the average temperature inside your home would normally be maintained at around 22 C. Depending on your glazing choice the surface temperature of your glass inside your window would be as follows: Single Glazing 3.2 C (4mm clear gas) Traditional Double Glazing 12.4 C (4mm / 12mm a.s. / 4mm - air filled clear unit) ClimaGuard Neutral 70 Double Glazing 16.4 C (4mm / 16mm a.s. / 4mm - 90% Argon filled unit, ClimaGuard Neutral 70 on surface #3) It is this difference in the surface temperature of the glass that dictates whether you get condensation build up, and cold downdrafts caused by your glazing. ClimaGuard Neutral 70 maximizes the usable space around windows as well as reducing your heating energy costs. Inside winter conditions - heat is absorbed and re-radiated back into the room when a ClimaGuard Neutral 70 coating is incorporated into an I.G. unit. Outside winter conditions Reduction in heat loss Reduction in cold spots in the room Reduction in condensation on the windows Reduction in down drafts around the windows Hot Weather Climates During the summer, the temperature outside may be 35 C, on average the temperature inside your home would normally be maintained at around 22 C. Depending on your glazing choice the Total Heat Gain would be as follows: Single Glazing 421 W/m² (4 mm clear gas) Traditional Double Glazing 343 W/m² (4 mm /12 mm a.s. / 4 mm - air filled clear unit) ClimaGuard Neutral 70 Double Glazing 247 W/m² (4 mm / 16 mm a.s. / 4 mm - 90% Argon filled unit, ClimaGuard Neutral 70 on surface #2) 28% better performance than traditional Double Glazing (The lower the total Heat Gain number the better the performance) Total Heat Gain = total net heat gain to the indoors due to both the air-to-air thermal conductance and the solar heat gain. The units are W/m². Traditional insulating glass transfers about 80% of total solar energy into the living ambience, often creating intolerable heat in our homes during the summer. By using ClimaGuard Neutral 70 glass, solar heat getting into the room can considerably be reduced because this type of glass transmits only 57% of total solar energy. Therefore, the inside glass temperature will be lower, and in case of air conditioning, remarkable energy savings can be achieved. Inside summer conditions HEAT Outside summer conditions - radiant heat is absorbed and re-radiated back into the environment when a ClimaGuard Neutral 70 coating is incorporated into an I.G. unit Reduction in solar energy transmission Reduction in transmission of radiant energy (long wave energy during the daytime or nighttime)
