Endura Flap Thermo Panel with Dual-Pane Glass

This panel is built for homeowners who want insulation and security without replacing their sliding door. The dual-pane Low-E glass works alongside the magnetic sealed Endura Flap to limit drafts and solar gain, creating a more comfortable environment than single pane inserts.

The Endura Flap is designed to remain flexible in subzero conditions while resisting deformation in heat. Its three sided magnetic closure forms a consistent seal, helping it stay shut during heavy gusts, even up to 50mph!

The aluminum frame balances strength and profile. At one inch thick, it fits securely into most sliding door tracks while maintaining a streamlined appearance. Adjustable height locks compress the panel into place, creating a stable fit without drilling into the door frame.

When a panel insert prevents your sliding door’s native latch from engaging, the included steel Slide Lock provides a dedicated locking solution. It mounts to the frame and creates a secure stop point so the door cannot be forced open from outside.

Panels are available in three standard height ranges or custom built to match uncommon track measurements. Taller or wider configurations ship in two sections for easier transport, then assemble with included hardware before installation.

With controlled pet access, durable materials, and thoughtful security integration, this panel is engineered to deliver everyday convenience without compromising the performance of your sliding glass door.
