Air-Filled IG Units

Why Choose
​Air-Filled IGU

​Often enough when considering of purchasing replacement vinyl windows or patio door that the question arises on whether to choose gas versus air for an insulating glass unit (IGU).  The insulating glass unit is comprised of two lites of glass, making-up four sides for optimum insulation.  The glass panes are separated by aluminum spacer bars and sealed to produce a hermetically sealed area and prevent any condensation within the unit. IGU’s reside inside the vinyl frame panel and are specifically designed to keep your space warm during winter or cold through the summer period.  In selecting low-e silver coated glass and filling the space between double panes with argon, krypton or any other gas and even dehydrated air can further enhance energy, solar and acoustic of windows and doors insulation performance.

Gases such as Argon are denser than air, which in turn will reduce heat transfer in IGU’s by 16% over dehydrated air. For even greater results, Krypton and Xenon, are alternative choices that most consumers may resolve to purchase depending on he width of the frame structure to increase their vinyl window energy efficient scores.However, these usually recommended substitutes are much more expensive due to being a scarce resource with limited amounts concentration in the atmosphere.   ​

​The other concern involves maintaining the gas fill levels over time. Gas and air leakage are inevitable; nevertheless, rate at which gas or air leaks varies between the two. Scientists usually refer to this basic principle as “ The law of Partial Pressures.” Whereby negative pressure within the IG unit will force the glass to deflect, and as a result cause visibility distortion.* Thus consumer will be able to see glass corrosion changes in the forms of various stains, and smear marks that will distort the window view. Consequently, thermal advantages will be lost.
​
Therefore Eco Glass promotes to both private homeowners and business affiliates to consider a more affordable and equally reliable air-filled IG Units that will prolong your vinyl window service.
