PDS Light

The PDS Light Door Seal is designed to seal the small gap between the door slab and door stops, preventing sound and air from leaking through the perimeter of the door. Its ultra low-profile design allows it to install directly over existing wood or metal door stops, making it ideal for both new construction and retrofit applications.

The soft, compressible foam core creates a tight acoustic seal while allowing the door to close smoothly with minimal force. This makes it an excellent choice for residential, studio, and commercial soundproofing projects.

For high-STC rated soundproof doors, pair the PDS Light with a PDS Rubber Door Seal to create a dead air space between the two seals. This combination maximizes door jamb gasket performance, achieving near zero sound loss around the door perimeter.

Each PDS Light Door Seal includes all required fasteners and manufacturer installation instructions. Below is a summary of the installation process.

The PDS Light is designed to mount directly over existing door stops. Installing it over the stops is essential, as the seal’s thin profile will not properly close the perimeter gap if mounted elsewhere.

Use the included fasteners to secure the seal through the slotted mounting holes, which allow for side-to-side adjustment—ideal for doors that are slightly bowed or uneven. For best performance, the 1/4" rubber should compress to about 1/8" when the door is closed, ensuring proper soundproofing and a tight seal.

Once the seal is correctly aligned, install the included cap cover to conceal the fasteners for a clean, professional finish. Make sure the seals are in their final position before installing the cap, as removal may damage the finish. Replacement cap covers are available, if needed.

To ensure a precise fit, accurate measurements are essential before cutting your PDS Light Door Seal pieces.

Width (Header Piece):

Measure the distance between the two vertical door stops at the top of the door frame. This measurement determines the exact length to cut your PDS Light header piece.

Height (Leg Pieces):

Measure from the floor or top of the threshold to the bottom edge of the horizontal door stop (after installing the header piece). This measurement determines the correct height for each PDS Light leg piece.

Refer to the diagram below for a visual guide on how to measure and cut your PDS Light components accurately. Proper measurements ensure a tight, continuous seal for maximum sound isolation and energy efficiency.

Independent soundproofing tests show that the PDS Light Door Seal performs as well as or better than larger perimeter door seals commonly found online from other manufacturers and suppliers. Our testing confirms that seal size is not the key factor in sound isolation. What matters most is the seal’s material quality, ease of installation, and its ability to compress properly while maintaining full contact with the door surface.

The PDS Light is engineered with high-quality acoustic foam that compresses 25% to 50% with minimal force, creating a continuous airtight seal along the entire door perimeter. This ensures maximum STC performance and consistent sound isolation without increasing door-closing resistance.
