Spacers
SPACERS
A spacer is placed within an insulating glass unit to separate two or more lites of glass. Tecnoglass’ insulating glass spacers are available in two colors, three materials and a variety of thicknesses. When specifying an insulating glass unit, it is necessary to specify all three; color, material and thickness.
Materials
Tecnoglass offers three spacer material options: Aluminum, Stainless Steel and Warm-Edge. More stringent energy requirements have increased the demand for alternate spacer material options in order to improve the edge-of-glass U-value.
Finishes
The spacers are available in a black painted finish or a mill finish that has a silver tone. The color doesn’t affect the solar performance of the insulating glass. Most existing buildings feature mill finish spacers, since they have been the standard in the glass industry for years. However, more designers are taking advantage of the cleaner appearance of the black painted finish. This finish tends to better blend in with gaskets and framing, thus minimizing the spacer’s visual impact.
Thickness
The thickness of the spacer is the space between two glass lites in an insulating unit. The thickness of Tecnoglass’ 1” insulating units are created using a 1/2” (13.2 mm) nominal thickness spacer, but other alternative thickness spacers are available as well. The solar performance is affected by the thickness spacer, so it is essential to specify the thickness desired.
Aluminum
This is the most popular and most frequently used spacer because of its availability and malleability.
The available thicknesses are:
Stainless steel
The stainless steel spacer has 1/10 of the thermal conductivity of an aluminum spacer. The available thicknesses are:
Evo
The Evo spacer reduces the edge conductivity, therefore reduces the heat transfer into the building. The available thicknesses are:
