Glass spacers—sometimes simply called spacers—are used in insulating glass units (IGUs) to create a space that physically separates the lites of glass. That space it creates is sometimes filled with inert gases that add to the insulating properties of the IGU.
What are warm edge spacers?
Warm edge spacer bars insulate the edges of a sealed unit and keep the panes of glass apart. When your home is warm in comparison to outside, heat escapes through the spacer, leaving the inside edge of the window colder than the rest of it. This then means you need more heating in order to warm up your home.
What does a spacer bar do?
A spacer bar is used to separate the panes of glass forming a cavity width that offers thermal insulation. The spacer bar also holds the desiccant, and the small holes in its surface allow the desiccant to adsorb water vapour from within the sealed cavity.
What are super spacers?
Super Spacer® is an insulating and energy efficient glass system. The edge spacers of these windows are made of all-foam construction with zero metal, giving them low conductivity. Super Spacer® is made of 100% polymer structural foam. It creates thermal efficiency through no presence of conductive materials.
What is the purpose of warm edge glass spacers?
A warm edge spacer is a type of spacer bar used in insulated glazing. It separates the panes of glass in double or triple glazing, or curtain walling and seals off the air cavity between each.
What is an intercept spacer?
Intercept spacers feature a unique, one-piece, tin-plated or stainless steel, U-channel design that creates an effective thermal barrier to help reduce conducted heat loss through the window.

What thickness is double glazing glass?
Today’s standard double glazing units are generally 28mm in thickness with a configuration of 4-20-4mm, which represents, glass thickness, cavity depth and glass thickness. As standard, most double glazing should be supplied with argon cavity gas, at least 1 low-e coating and a warm edge spacer.
What is super spacer made of?
Super Spacer® is an insulating and energy efficient glass system. The edge spacers of these windows are made of all-foam construction with zero metal, giving them low conductivity. No other window spacers on the market today can offer this claim! Super Spacer® is made of 100% polymer structural foam.
What are the spacer bars of IGU made of?
The basic spacer bars are (were) made of aluminium, which is a very good heat conductor. The combination of glass and aluminium spacer bar in the composition of IGU therefore represents a thermal bridge, which reflects in the low temperature of the edge of the inner glass pane and consequently in the formation of a condensate.
What is insulated glass unit (IGU)?
Insulated Glass Unit (IGU) is a structure consisting of two or three glass panes spaced apart with a spacer bar and hermetically sealed, and forming one or two insulated chambers filled with inert gas or dried air.
What is the spacer bar filled with?
To ensure the air within the sealed unit remains dry, the spacer bar is filled with a molecular sieve desiccant. Warm Edge Spacers have evolved as a result of research into IGU spacer systems which break the thermal bridge at the transition of the glass and frame edge.
What is a thermal bridge in IGU?
The combination of glass and aluminium spacer bar in the composition of IGU therefore represents a thermal bridge, which reflects in the low temperature of the edge of the inner glass pane and consequently in the formation of a condensate. Alternatives are so-called “warm edge” spacers.
