Sheffield® Fusion-Welded Vinyl Windows

About

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 barrier, while the extra-thick, fusion-welded frame 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 mainframe on double-hung and sliding windows complement any home’s style.

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