Realize All the Benefits of High Solar Gain Glass. LoE-180 is the perfect cold remedy. Ideal for passive solar applications, it allows winter sun’s heat to pass into the building while blocking heat loss to the outside. In a double-pane unit with argon fill, Cardinal LoE-180 glass delivers an ER of 45,U-factor of 0.26 and visible light transmission of 77%.

This means high levels of cold weather comfort for occupants. Moreover, the warmer indoor glass surface means relative humidity can be controlled and maintained properly, improving occupants’ comfort and surroundings. Building owners and/or managers benefit from significant energy savings. mayBecause LoE-180 transmits more natural light, architects may be able to reduce lighting loads, resulting in even more savings. Naturally saving energy is also good for the environment.

Cardinal LoE-180 glass can be supplied in stock sheets and can be tempered and laminated for stock delivery. Maximum stock sheet size: 96”x144» (2.43 meters x 3.65 meters).

Cardinal LoE Glass Sets the Standard for Energy-Efficient Glass. Our patented, state-of-the-arts puttered coatings are unmatched by any other glass manufacturer. These high-transmission coatings are virtually transparent, blocking the heat and reducing solar gain, while optimizing light transmission. Infact, our LoE2 and LoE3 coatings actually out perform tinted glass, which is often used.

Cardinal produces nearly 700 million square feet of coated glass annually, at seven coating plants across the U.S. Our Intelligent Quality Assurance Program (1.Q.) ensures the quality of every piece of glass. Using our patented inspection systems, we thoroughly examine the glass for exterior and room side colour, visible transmission/reflection, IR reflection and edge deletion.

Get Superior Thermal Performance Year Around. LoE2-272 is ideal for any climate and weather. Just look at the numbers. In a double-pane unit with argon fill, Cardinal LoE2-272 glass delivers an SHGC of 0.40, U-factor of 0.25 and visible light transmission of 70%. All with no haze or bluish cast.

This means high levels of year-round comfort for occupants. Moreover, the warmer indoor glass surface means relative humidity can be controlled and maintained properly, improving occupants’ comfort and surroundings. Building owners and/or managers benefit from significant energy savings. And because LoE2-272 transmits more natural light and reduces solar gain, architects may be able to reduce lighting and air conditioning loads, resulting in even more savings. Naturally saving energy is also good for the environment.

Cardinal LoE Glass Sets the Standard for Energy-Efficient Glass. Our patented, state-of-the-art sputtered coatings are unmatched by any other glass manufacturer. These high-transmission coatings are virtually transparent, blocking the heat and reducing solar gain, while optimizing light transmission. In fact, our LoE and LoE2 coatings outperform tinted glass often used.

Cardinal produces nearly 700 million square feet of coated glass annually, at seven coating plants across the U.S. Our Intelligent Quality Assurance Program (I.Q.) ensures the quality of every piece of glass. Using our patented inspection systems, we thoroughly examine the glass for exterior and room side colour, visible transmission/reflection, IR reflection and edge deletion.

Get the Perfect Balance of Solar Control and High Visibility. Just look at the numbers. In a double-pane unit with argonfill, Cardinal LoE3 -366 glass delivers an SHGC of 0.27, U-factor of 0.24 and visible light transmission of 63%. All with no interior-darkening tints and virtually no exterior reflectance.

This means a high levels of year-round comfort for occupants. Moreover, the warmer indoor glass surface means relative humidity can be controlled and maintained properly, improving occupants’ comfort and surroundings.

Building owners and/or managers benefit from significant energy savings.And because LoE3 -366 transmits more natural light and reduces solar gain, architects may be able to reduce lighting and air conditioning loads, resulting in even more savings. Naturally, saving energy is also good for the environment.

Double-pane windows become triple-pane performers

There i’s no need to go to triple-pane windows to meet the various energy-saving guidelines. No need to invest in redesigning your windows and altering your manufacturing processes either. A double-pane IG unit with LoE-i89 can meet the guidelines.

LoE-i89 is sputtered onto the indoor lite, the #4 surface, thus reflecting escaping heat back into the room and lowering U-Factors. Coupled with our LoE2 or LoE3 glass and argon fill, this double-pane unit delivers performance much better than clear triple-pane — a centre of glass U-Factor of just 0.20 compared to 0.37 with clear triple-pane.

To surpass the U-Factor performance of our LoE-i89 double-pane unit, you would need to go to a triple-pane unit with a low-E coating in each gap.
