Double Window Envelopes

A double window envelope solves a problem that single window envelopes only solve halfway. The single window shows the recipient address. You still have to print or label the return address on every envelope in a mailing run. The double window eliminates both. Two precisely positioned clear poly-film panels display both the return address and the recipient address directly from the printed document inside. For businesses running regular invoice, statement, check, or payroll mailings, that means the envelope is fully addressed before it's sealed without anyone touching a label, a printer, or a handwriting tool. At Business Envelopes, we carry double window formats for checks, invoices, statements, and standard #10 correspondence, in gum flap, peel-and-seal, and flip-and-stick closures, with free shipping on every order.

How Double Window Business Envelopes Work

The key to understanding double window envelopes is window placement. Unlike a single window envelope where only the recipient address field matters, double window designs have to align two separate address zones with two separate printed fields on your document simultaneously. The top window captures your company name and return address from the upper portion of the document. The bottom window captures the payee or recipient address from the standard address block position. When the document is folded correctly and inserted, both panels display the right information without any adjustment.

For check formats, the bottom window placement is especially critical. It's positioned to display the payee address while keeping the check amount, routing number, account number, and memo line concealed behind the opaque envelope body. That's the difference between a double window check envelope and a general-purpose double window envelope. The window height and position on a check envelope is calibrated specifically so financial fields never appear in the visible panel. Our check formats align with QuickBooks, Quicken, Sage, and all standard laser check layouts without any document reformatting required.

Double Window Envelopes: Every Format We Carry

Double Window Check Envelopes, Gum Flap

Check-size format with two windows aligned to standard laser check address fields. Security tint interior blocks check contents from showing through the envelope body. Moistenable gum flap for traditional sealing. Compatible with QuickBooks, Quicken, and standard business check formats.

Double Window Check Envelopes, Peel and Seal

Same check-format window alignment and security tint, with peel-and-seal closure instead of gum flap. No moisture required. The protected adhesive liner prevents pre-activation during storage, and the bond sets on contact under firm pressure. Faster per-piece sealing on payroll and vendor payment batches.

Double Window Check Envelopes, Flip and Stick

The flip-and-stick reverse flap design uses an adhesive panel on the envelope body. Fold the short tab down onto the adhesive and press. No liner to remove, no moisture needed. Faster production throughput than peel-and-seal when envelopes are processed immediately after loading rather than stocked before a run.

Double Window #10 for Invoices and Statements, Gum Seal

Invoice and statement format in standard #10 size (4 1/8 x 9 1/2 inches). Top window shows return address, bottom window shows recipient address, both from the printed invoice or statement inside. Gum flap closure. Compatible with standard billing software layouts including QuickBooks and Xero.

Double Window #10 for Invoices and Statements, Self Seal

Same #10 invoice format with flip-and-stick self seal closure for high-volume billing runs. No moisture. Fold, press, sealed. Used by accounting departments, healthcare billing offices, and financial services firms processing monthly statement batches.

Double Window Envelopes for Invoices and Statements, Peel and Seal

Invoice and statement double window format with peel-and-seal closure. The liner-protected adhesive is the right choice when envelopes are stocked in advance of a mailing run rather than processed immediately, since the liner prevents pre-activation from humidity or stacking pressure.

#9 Double Window Envelopes, Peel and Seal

Double window format in the #9 size (3 7/8 x 8 7/8 inches). Fits inside a standard #10 outer envelope as a return or reply mailer. Both address windows display from the document or card inside. Used for return payment envelopes included in outgoing billing statements.

#10 Double Window Envelopes

Standard #10 commercial size double window for general business correspondence where both sender and recipient addresses need to show from the document inside. No label, no addressing, no printing on the envelope face. Clean white 24 lb wove stock.

Business Envelopes Printing: Custom Options on Double Window Formats

Every double window envelope in this catalog is available with custom printing on the exterior face. Return address, company name, logo, and tagline can all be printed directly on the envelope stock before it ships. For businesses that want the full branded treatment on outgoing correspondence, custom printed double window envelopes mean every piece that goes out carries both address panels from the document and the company identity on the face without any additional prep work at the office.

This is the configuration most accounting departments and billing operations settle on for recurring mailing programs. The envelope handles addressing automatically through the windows. The custom printing handles branding and return address verification. Nothing gets touched manually before sealing. For custom printing on double window formats, printed orders ship in 7 to 10 business days from proof approval. Artwork stays on file for reorders.

Business Envelopes Wholesale: Bulk and Volume Pricing

Double window envelopes are used in volume. Payroll runs, monthly billing batches, weekly accounts payable, quarterly statement mailings. The per-unit cost at standard retail quantities works for occasional use. For operations running these envelopes on a recurring schedule, bulk pricing reflects the actual economics of volume purchasing and makes a meaningful difference across a full year of mailing program costs.

We offer wholesale pricing on double window formats for businesses, resellers, and organizations that order regularly in quantity. No minimums on single orders, free shipping across the contiguous 48 states, and volume pricing that scales with quantity across all formats.
