Krypton Gas

The first glass windows were single pane. Later, it was discovered that two panes create a dead air space that greatly reduces heat loss. After that, engineers found out that the type of gas between the two panes makes a big difference. (Remember, air is a gas too.)

In a sealed glass-insulating unit, the difference in temperature on each side of the glass causes an air current between the two panes (convection). Just like in a room, these air currents carry heat to the top of the window and cooler air settles at the bottom. The more air movement there is between the two panes of glass, the more heat is transferred from one side to the other. When the air space between the glass is filled with a heavy gas instead of normal air, there is less heat transfer between the inside and the outside of your home.

But what kind of gas?

Air - Many window companies still just use plain old air. It costs nothing and if the homeowner doesn’t ask… they’ll never know.

Argon - Others use Argon. Argon is 35% denser than air, so that’s a step up, but because it’s still a relatively light gas, energy is able to quickly transfer through a double pane window.

Krypton - Krypton is absolutely the best choice. An extremely dense gas, it is nontoxic, nonreactive, clear, odorless AND 185% denser than air and 105% denser than Argon! Triple pane Penguin Windows don’t just have one Krypton barrier… they’ve got TWO between the inside and outside of your home. It’s so efficient that Penguin Windows insulate better than the walls in some homes! So why doesn’t every window company use Krypton? Because Krypton costs a lot more to make and install than plain old air or Argon. If we were willing to sell double-pane windows with air or Argon we’d make a lot more money, but we’re committed to offering the highest quality, most energy efficient windows you can buy.
