Setting blocks are also used to provide stress relief as vinyl windows contract and expand over different temperature conditions. Our setting blocks will help prevent the glass from cracking and help protect the integrity of the glazing bead.

Die-Cut Window Gaskets

Does your fenestration application need a specific gasket? There's no need to settle! We will work closely with you to create the perfect die cut window gasket to enhance your product. We  offer a full complement of industrial grade materials and can create custom die-cut window gaskets from any of them. Best of all, we will provide guidance and help you choose the best material for your unique product needs.

Foam Wrap Tape, Jamb Foam, or Window Wrap Tape

We offer foam wrap tape or jamb foam in both standard and compressed formats. Our jamb foam is designed to prevent air leakage from around original construction window installations and replacement installations.

It eliminates the need for spray foam sealer or insulation stuffing by providing a seal around the window between the window jamb and the rough opening. Crafted from quality materials, our easy-to-apply window wrap tapes are designed to:

  • Create tight seal between window and framed opening;
  • Be easy to use in a simple peel-and-stick format for quick application; and
  • Reduce shipping and storage costs with our compressed format.

Chimney Blocks /Jamb Plugs / Air Dams / Balance Plugs

Chimney blocks, jamb plugs, air dams, or chimney plugs are essentially designed to prevent air from flowing up the window balance track by sealing the area surrounding the balance. With our custom jamb plugs, chimney blocks, air dams, or balance plugs, your windows will:

  • Achieve higher energy efficiency,
  • Experience reduced wind noise, and
  • Have less condensation at the rails.

Regardless of the type of balance being used or how the product is mounted, Frank Lowe can create the perfect chimney block for your fenestration application — including offset or center holes — even double balance systems. We offer balance plugs for an endless array of fenestration products:

  • Single/dual/off-center/no-hole
  • Available in custom sizes
  • Promote compliance with building codes (AAMA/WDMA -101/I.5.2/A440-08)
