Weatherseal Products

Schall-Ex® L-15/30 WS Pivot

The Athmer Schall-Ex® high-performance drop seal is the standard for sound isolation. 

The pivot model features an adjustable roller actuator which can negotiate the edge of your jamb, wherever the door sits in the frame.  

As you may know, in order for the whole thing to work, the drop seal needs to be mortised alongside the pivot closer body, so a thicker door is required to accommodate both. Using a FritsJurgens System M or System One pivot in the door, you are looking at a minimum 2-3/4" door to provide the required clearances.

Sure, the actuator is cool, but it's what's packed the profile that is really the reason to specify Athmer dropseals.

  • Sound reduction up to 50db
  • Parallel and self-leveling deployment (no dragging).
  • Self-extinguishing silicone seals.
  • Removable actuator for protection of seals during construction.



FOAM seal has an excellent sealing function regarding multiple aspects:

  1. Extraordinary memory - the polyurethane foam gives high durability and rebound performance
  2. Stability - high thermal conductivity and stain proof
  3. Available in various colors
  4. Sound-proof function - foam is a good absorbent of sound.

Economize on energy - powerful sealing performance that prevents hot air from coming in.

Expanding Foam Sealant Tape

Expanding foam sealant tape is a compressible tape that combines the sealing properties of closed cell foam with the flexibility and conformability of an open cell tape. New foam sealant tape replaces caulk, spray foam, putty and other liquid sealants to provide an airtight and watertight seal for over 20 years. Expanding foam sealant tape does exactly as the name implies to fill gaps, seal joints, and provide insulation in window and door applications by blocking air, vapor, moisture and dust infiltration, especially on irregular surfaces and spaces.

Foam sealant tape is also great for gasketing, weatherstripping and more. Saturated foam sealant tape is a clean and convenient alternative to traditional sealants, which can become messy and difficult to use, especially in varying temperatures and environmental conditions. On the other hand, LAMATEK’s expanding foam tape remains easy to use.

This unique tape is made from a resilient, open cell, expanding urethane foam that is impregnated with a proprietary saturant so it provides superior sealing qualities without the compression set or restrictions of most closed cell foams.

CX Series Kerf Mount Casement Seal

The CX series seal from Coda is a foam-filled bulb seal with a patent-pending rigid carrier design to aid in easy installation into vinyl profiles, as well as the ability to wrap a window after it has been welded. With Coda's patented installation process, operators can easily "roll" the bulb seal into a sash or frame with minimal effort and be sure the seal is installed securely and at the correct depth into the kerf slot.
