LoĒ²-270 Glass

Go beyond ordinary low-e glass. Let LoĒ²-270 help you handle the weather – any weather. Solar control for just about the coolest windows under the sun.

The patented LoĒ²-270 coating provides high performance solar control and visual clarity.

The sun doesn’t stand a chance against LoĒ²-270. It’s the perfect glass for fighting the heat. It reduces solar heat gain by 50% or more when compared to ordinary glass. In fact, its solar heat gain coefficient is better than code requirements. And because of its clarity, LoĒ²-270 outperforms tinted glass typically used in sunny climates.

The superior insulating capability of LoĒ²-270 is a key factor in the construction of comfortable windows for cold climates. The dramatic comfort improvement from windows with warm glass surfaces also means the relative humidity of the indoor air can be controlled and maintained properly. Proper humidity levels (not too much, not too little) will improve comfort and promote a healthier living environment.

EnviroGuard LoĒ²-270 windows are ideal for all weather conditions in most climates. In summer, its patented coating blocks 86% of the sun’s harmful ultraviolet rays and 63% of the sun’s heat. It even outperforms the tinted glass often used in warm climates. You can see out and the light shines in, with no heavy bronze or smoke colored tints to darken the personality of your home. In winter, it reflects heat back into rooms.

FOR EVEN GREATER FADE RESISTENCY AND COMFORT IN ALL CLIMATES, CONSIDER ENVIROGUARD LoĒ³-366.

Save energy with glass so smart, it can control your comfort.

Although windows provide beautiful views and wonderful natural light, they can also account for up to 50% of the heating and cooling energy consumed in a home. In the summer, EnviroGuard LoĒ²-270 windows keep your home cool and comfortable by rejecting the sun’s heat and damaging rays. In the winter it helps your home stay warm and cozy by blocking heat loss to the cold weather outside. In short, it can save energy year around.

* Thermostat settings are the largest variable in establishing the heating and cooling energy savings potential with window replacements. If you tolerate the discomfort from your current windows and don’t change thermostat settings with the weather, consider the savings suggested from the “Fixed Thermostat” column. If on the other hand you frequently adjust the thermostat, add space heaters to compensate for cold rooms, or close drapes/blinds to block the sun consider the additional savings suggested in the “Equal Comfort” column.

Heat/Cool portion of your energy bill: DOE estimates that in 2005 the average house spent $2,003 on utilities and that 43% of this total ($886) is for heating and cooling energy. (http://buildingsdatabook.eren.doe.gov/TableView.aspx?table=2.3.10). Savings values are average of multiple locations within climate zone. “Average” house as described in the Buildings Data Book at http://buildingsdatabook.eren.doe.gov/TableView.aspx?table=2.2.7 The model house is described as a mid-1970’s single-story dwelling with natural gas furnace, central air-conditioning, adequate insulation, and double-pane windows. Window orientation set as uniformly distributed on all sides to represent a neighborhood average and the total window area set to 15% of the floor area. Interior shading devices are presumed to be closed 50% of the time throughout the year. “Fixed Thermostat” conditions are 70°F for heating and 75°F for cooling. “Equal Comfort” thermostat settings determined using window thermal comfort research from the University of California at Berkeley (http://www.cbe.berkeley.edu/research/pdf_files/SR_NFRC2006_FinalReport.pdf). The existing double-pane windows used heat/cool thermostat setpoints of 72°F/74°F to match the comfort of LoĒ²-270 glass at 70°F/78°F. House heat/cool energy simulations used the Resfen program from Lawrence Berkeley National Lab (http://windows.lbl.gov/software/resfen/resfen.html).
