Insulated Glass
Insulated glass, also named insulated double glazing, double glazed panels or double glazed units, it’s a hermetically sealed multi-glass combination consisiting two or more panes separated by a spacer filled with high efficient desiccant. To ensure the sealing effect, first sealing finished by polysulfide adhesive and second by strucural sealnt. The most important function of insulated glass is reducing thermal loss, achieve lower energy consumption and good transparency.
LETEL® Glass Offers Architectural Insulated Glass.
Thermal Insulation
The glass thermal conductivity is 0.688 while the air thermal conductivity is 0.027,glass has 27 times higher thermal conductivity than air.The air gap between double glazed units can take advantage of the low thermal conductivity inside to decrease thermal conductivity.
Insulated glass made with clear glass ,U value is only half of monothlic glass,in addition to high performance low-E coating,U value can decrease only 0.6W/M2.K.The glass has high termal insulation perfromance and used in passive house.
Sound Insulation
Insulated glass can reduce noise by 27-50 decibels, and 80 dB of traffic noise outside can be decreased to only 50 dBs to indoor.Combing with laminated glass,insulated glass sound insulation performance can be Maximized.
| Glass Configuration | 6-12-6 | 6-12-6-12-6 | 6-16-6-16-6 | 66.4+12A+66.4 |
|---|---|---|---|---|
| STC | 34 | 37 | 39 | 45 |
| OITC | 29 | 29 | 29 | 37 |
Dew Free
Dew occurs where condensation appears due to the difference between interior and exterior temperature.
Because the inner glass that is in contact with the indoor air is affected by the air barrier, even if the outer layer contact is low, there is no condensation on the glass surface due to the temperature difference. Insulated glass dew point up to -40 ° C ,if filled with argon ,dew point decrease to -80℃.
Long Lifetime
Insulated glass with structural silicon sealant warranty time is 10 years,actually the IGU lifetime can reach 20-50 years.
Light Weight
Even though the air space in insulated glass added the glass thickness,but the insulated overall weight is almost same as the glass weight.
6-12-6 insulated glass weight 30kgs/m2, this significantly decrease the overall building weight based on offering excellent thermal insulation and sound ,prfoof function.For skycrapers with hundreds meters high,the building safety can be ensured.
