insulating units


Insulating glass refers to two or more lites of glass hermetically sealed around the edges with an air space between to form a single thermal unit.

For insulating units there is reduced heat transfer across the air space. The effect is even more pronounced when further panes and air spaces are added. High air temperatures, low rates of air movement.

warm edge spacer


Super Spacer is considered the best option in reducing condensation and reducing metal conductivity between the glass & spacer. Super Spacer is considered True Warm Edge Technology, when combined with a low Emissivity glass & argon gas, it is widely recognized by Energy Star.

thermal edge


Still considered warm edge which feature is a metal core with a polymer bridge that enhances thermal performance. Thermal edge spacers are less conductive that aluminum, glass edge touch the polymer, not the aluminum, therefore establishing a warm-edge.

This reduces condensation and raises the temperature of the edge of the glass, prevents moisture vapor on glass eliminating likelihood of fungi, bacteria & molds.


Aluminum Spacer


Aluminum Spacers are still manufactured but rarely used in vinyl windows & government buildings. Commercial projects are normally the spacer of choice for its cosmetic appearance & structural performance.
