Insulating Glass Units (IG Units) can be made with air or other gases between the two sheets of glass. We use air-filled because the seals have a longer life with air. While we can provide Argon gas filled windows at an increased price, we caution that this could result in reduced life due to seal failure.

Capillary tubes are used in insulated glass in order to equalize pressure between the inside and the outside of the unit. During transit the insulated unit can travel the a variety of altitudes and the unequal pressure can weaken the seals, therefore shortening the life of the insulated unit. These tubes are to be removed prior to install and to be sealed with a silicon based sealant.

I used one day glass to order two pieces of glass to replace my bedroom window glass that where fogged up from failings dual pain window seal. I ordered the glass on online very easy just a couple of steps to order and four days later i had my glass done at half the cost of local glass company. Will check them in my contacts 👍

Ordered replacement windows for a roll up shop door. The new window glass units arrived packaged well with capillary tube (wire) provided. Pulled the wire and let them sit. Siliconed them shut and installed the window units. Perfect fit. The shop door looks great again.
