Sheffield

The superior performance of Sheffield® windows starts with innovation. Every precision-engineered component contributes to superior energy savings. The multi-chamber design helps trap dead air to produce an effective insulating barrier, while extra-thick, fusion-welded frames and sashes provide superior structural strength and create a permanent barrier against air and moisture infiltration, adding up to greater energy savings – and lower utility bills.

Sheffield windows feature a sloped sill helping to prevent air and water infiltration while maintaining a timeless, detailed appearance. Beveled mainframes on double-hung and sliding windows complement any home style.

Best yet, Sheffield windows are covered by Alside’s impressive Lifetime Limited Warranty* for complete peace-of-mind.

ClimaTech

Alside’s exclusive ClimaTech high-performance insulated glass package is a state-of-the-art combination of three energy-efficient elements, each contributing to a superior glass unit that may help to pay for itself in energy savings through all seasons.

Solarban® 60 Low-E glass from PPG

Solarban 60 Low-E glass (low emmisivity) helps reduce energy costs in two ways. In summer, Solarban 60 helps block out long-wave radiation (direct sunlight) from the sun, keeping your home cooler. In winter, Solarban 60 helps retain furnace heat while allowing warming, short-wave solar rays to enter the home, putting less strain on your furnace to maintain a comfortable warmth.

Intercept™ Warm Edge Spacer from PPG

The Intercept Spacer System is designed to keep the edges of the window glass warmer. Even with insulating glass, if the edges are not sealed properly, the insulation of the window as a whole may be compromised. The Intercept spacer creates a “warm edge” seal for superior insulation and reduced likelihood of condensation at the edges of the window.

Insulating Argon Gas

Argon gas is a colorless, odorless, nonflammable, nontoxic, inert gas that is sealed between the two panes of glass. Heavier than air, and completely safe to humans and animals, the argon gas provides an additional layer of insulation, increasing energy-efficiency and also acting as a sound barrier to help deaden outside noise.

ClimaTech Features

• Improved winter and summer thermal comfort
• Increased heating and cooling season energy and cost savings
• Reduces peak loads for lower HVAC costs
• Helps reduce window condensation
• Helps deaden outside noise
