Large Commercial Window Envelopes for Business Mailings

Western Sulphite® #14 window envelopes are a dependable option for businesses, offices, schools, accounting departments, medical offices, legal firms, municipalities, and other organizations that mail larger documents or high-volume correspondence. The 5" x 11-1/2" format provides extra room compared to smaller commercial envelopes, while the 24 lb white sulphite paper gives outgoing mail a clean, professional appearance.

Each envelope features diagonal seams, a flap-down design, and a traditional remoistening seal. The poly window is positioned for standard address visibility, helping streamline mail preparation when documents are printed with the address already aligned.

Printer Compatibility Note: This window envelope is not recommended for laser printers, as heat from laser printing may cause the poly window to shrink or warp.
