The material used to manufacture the glass spacer is one of the most important factors that deciding whether the windows are energy efficient or not. Glass spacers play an important role in a window’s overall performance,especially the thermal conductivity and thermal insulation performance, as they determine the amount of heat and cold that is able to pass through a window.
The 2 or 3 lites of glass panels in insulated glass are held apart by spacers.The quality of the materials used to produce spacers, their longevity, flexibility and thermal properties are critical.
WARM EDGE SPACER ADVANTAGE-INSULATED GLASS
Good spacer should have 4 important roles:
Absorb stress caused by thermal expansion and contraction
Block moisture and water vapor that can fog glass
Create a tight seal that prevents leakage of special gas fills
Increase the temperature of the edges of the insulated glass – this can help reduce condensation and increase overall energy efficiency of the window
Traditional double-glazed windows used metal spacer, typically aluminum. Aluminum is an excellent conductor of heat. During winter it conducts cold and makes the edges of the glass even colder. This decreases overall U-Factor of the window making it less energy efficient. In addition to the increased heat loss, the colder edge is easy to cause condensation. Aluminum spacer is usually square-shaped. This inflexible shape is typically a major reason for seal failures .
Warm edge spacer is new products that has low thermal conductivity,the advantage of warm edge spacer used in insulated glass and windows are:
Reduces Sealant Stress
Super Spacer’s thermoset polymer material expands and contracts and always returns to its original shape. Super Spacer sealed IG units last up to five times longer in durability tests than conventional single seal units.
Good spacer should have 4 important roles: Absorb stress caused by thermal expansion and contraction Block moisture prevents leakage of special gas fills
Improves Heat Flow Resistance
The all-foam formula blocks heat transfer and provides one of the best thermal performances available. Super Spacer resists heat flow 950 times more than that of aluminum. This means lower energy costs, less condensation/frosting and reduced chances for mold growth.
Good spacer should have 4 important roles: Absorb stress caused by thermal expansion and contraction Block moisture prevents leakage of special gas fills
Improves Glass Surface Temperature
Super Spacer’s extremely low thermal conductivity means less variation in the surface temperature of the
insulated glass unit. Super Spacer units withstand 140°F/60°C temperatures, 95-100% humidity and constant UV bombardment in the world’s toughest durability test – The P-1 chamber.
GLASS SURFACE TEMERATURE
Improves Sound Absorption
The closed-cell polymer foam in Super Spacer transmits very little sound compared to conventional aluminum spacers.
Acoustical laminated glass, Super Spacer and varying thicknesses of glass are recommended wherever noise from airplanes, trains or automobiles are a concern.
SOUND ACOUSTIC PERFORMANCE
Improves Condensation Resistance
Mold needs moisture to grow. Moisture can increase the likelihood of fungi, viruses and mites that can cause infections, allergies and asthma. The significantly reduced interior condensation or frosting means that the health problems associated with mold may be virtually eliminated.
