Use triple

For the design of energy -saving houses, engineers propose to use triple glass packets. Between the glasses, the space is filled with inert gas (crypton or argon) — this allows you to prevent a loss of 50% heat. The greater the distance between the glasses inside the double -glazed window, the better it performs its functions. For even greater protection, the double -glazed window is mounted in the so -called deep frames, which tightly cover the edges of the internal glasses.
