求購low-e玻璃

For the glass, I need two different quotes.
a) Just with one single 6mm float glass (tempered)
b) 5+12A+5 insulated glass, filled with Argon, anddouble silver coated Low-E on one side, the most important data is U-value of this kind of glass is 1.1 W/ (m2 K) or U-factor is 0.19 (Btu/ft2-h-F), it is much more better energy efficient glass.
