Casement Window Glossary

Laminated Glass

Laminate glass is a type of safety glass comprising of two pieces of glass with a clear vinyl inter lay. This glass may break under impact, but typically remains integral. Splinters and sharp fragments adhere to the inter lay. Laminated glass is ideal for area's where someone might fall against the glass, or to prevent forced entry.

Low E

Low E is a coating applied to one side of a glass pane to reduce it's emissivity. All Weather Clear Performance Low E uses silver oxide for a highly transparent, and low reflectivity low emissivity coating on our heat systems glazing.

Insulating Glass (IG)

Insulated glass units (IG or IGU) are a combination of two or more panes of glass sealed together using a spacer bar in a factory controlled environment. The sealed unit has an optimum air space which is filled with a gas fill such as air or argon gas, and produces a higher insulating glass panel.

Dual Pane

A glass unit consisting of two panes of glass held together by a sealant and a spacer, forming a sealed unit.

Argon Gas Fill

Argon is a colorless, odorless, non-flammable, non-reactive, inert gas. Argon gas fills are used to reduce heat loss in sealed units by slowing down convection in the air space. Argon gas is very cost efficient, and works in unison with Low E coated glazing.
