Prevent Bugs, Wind, and Dirt with Reticulated Foam Weep Baffle 

Our reticulated foam weep baffle is the perfect way to prevent air, bugs, and dirt from entering. While it allows water to exit the window system, the reticulated foam weep baffle works to eliminate clogging for free airflow. We can customize the reticulated weep foam baffle for any window design or size. And this material is extremely easy to place into the profile. 

  • Various PPI (pores per inch) available to match design requirements
  • Available with or without adhesive
  • Final product supplied bulk packed

Sill Pad Air Dam

Looking for a cost-effective way to prevent air from coming through the balance pocket? Frank Lowe's innovative sill pad air dam is designed for both single-hung and double-hung windows. Perfect for both aluminum and vinyl windows, our sill pad air dam also works on unpainted or painted windows. In either case, applying is easy and will never leave any residue or adhesive. Our sill pad air dams are highly effective at preventing:

  • Air coming through the balance pocket
  • Whistling noises
  • Winter condensation from freezing on glass
  • Dirt buildup collecting on the lock rail

Best of all, they work perfectly no matter what balance system you are using:

  • Constant Force
  • Spiral 
  • Block and Tackle
  • Works with all sill systems — pocket or sloped sills

When you apply the sill pad air dam, you'll never need to perform a lock rail adjustment because each pad is engineered with cutting-edge foam technology that quickly compresses and bounces back. You can opt for sill pad air dams in white, black, with or without adhesives, and in a vast array of custom sizes.

Custom Accessory Gaskets for Windows and Doors 

When it comes to gaskets for windows and doors, Frank Lowe will meet your needs and exceed your expectations. We offer hardware gaskets that are available in standard as well as custom designs. Although many of our accessory gaskets are crafted from polyethylene, we can customize your gaskets from several other materials. Other customization options include:

  • With or without adhesive
  • In gray, black, white, or tan to match windows 

And when we ship the final product to you, it's supplied kiss cut on rolls with the web scrap already removed. Our ability to go further and do more leads to faster and easier application in your assembly or manufacturing process. We also offer accessory gaskets bulk packed for easier kitting projects.
