We Build The
Window You Need
When you partner with OpenUp® windows, we give you the option to select the high-performance glass that is best suited to your needs. Based on your geographic location and the requirements of your project, we can help you select the glass that will best serve you—for years to come.
Glass and Solar Energy
SHGC, or Solar Heat Gain Coefficient, relates to the ways that direct sun can heat up the indoor space. In practical terms: the lower the number the better it is.
Our standard glass offering is for a hard coat electrolytically applied coating. Better insulation value is achieved with double-silver and triple-silver soft coats. The triple- silver coatings are most valuable in sunny climates and throughout the southern states.
Let’s Talk Glass Options
The standard option for OpenUp® is 1″ thick insulated glass. The “IG” package is made up of two pieces of 3/16″ tempered glass for safety separated by a black spacer. This creates a 5/8″ thick air pocket between the two layers—doubling the insulation over a single pane of glass. We also offer argon gas to replace the air between the two panes of glass which adds additional insulating value.
The insulating value of the glass is increased by adding a thin metal layer to the inboard layer of the outer pane. This layer reflects long-wave heat radiation. U-value is the conductivity rate of the glass and is the inverse of the insulating value. The lower it is the better the insulating value.
If you need more information, we are only a phone call or email away.
10 + 40 Year Warranty
When you invest in an OpenUp® pass-through window, you can rest easy knowing that no matter what happens—you’re covered.
For the first 10 years, OpenUp® protects every piece of your window apart from the glass. For the next 40 years after that, Accoya® ensures that your wood is safe from weather and pest damage—guaranteed.
