Efficient and Effective

Warm-Edge Spacer System

A window’s spacer system, or the component that separates glass layers, is remarkably impactful on the energy efficiency of the entire unit. The traditional spacer system can increase heat loss and cause condensation to form on the edge of the glass.

Window World s Warm-Edge Spacer is designed to block the path of escaping heat far more effectively, reducing condensation on winter glass. Non-conducive edges eliminate any glass-to-metal contact and contribute to a reduction of edge-to-glass temperatures, creating a more energy-efficient window. Featuring a unique design, these spacers are far more effective than their dated predecessors.

Temperature Control

High-performance Low-E coatings help maintain the perfect temperature

SolarZone Low-E glass coatings are created by applying a microscopic, undetectable metallic coating to the surface of an insulating glass unit. Its intelligent design blocks heat gain from the sun’s reflected rays in the summer but allows warmth from shorter solar rays into the house during cold, winter months.

See the difference Toggle between summer and winter to see Low-E Glass in action.

Winter Summer

Ideal Insulation

Argon gas is the perfect insulation for your windows.

We use argon gas as an insulating agent in our window products to help increase energy savings in your home. This colorless, odorless, nonreactive gas is the third-most-prevalent gas in our atmosphere. Its extremely low thermal conductivity and high density make it an ideal insulating agent.

See the difference Toggle between standard and SolarZone™ to see effects of argon gas insulation.
