The small gap that exists between the door slab and door stops (wood or metal strip the door rests against when closed) can be sealed using our PDS Light. Because of the ultra low profile, this perimeter door seal must install over the top of existing stops. The easy to compress foam allows the door to shut with a low closing force while fully sealing the sides and top of the door.
We recommend combining a set of PDS Light with a set of PDS Rubber to create a dead air space between the two rubber seals. Doing so will maximize the performance of the seal system to a near zero loss perimeter seal performance.
For the width, measure the distance between each vertical door stop. This measurement is the width you should cut for your PDS Light.
For the height, measure the distance between the floor, or top of the threshold, and the top horizontal stop. This measurement is the height you should cut for your PDS Light.
Use the drawing below for a visual explanation of how to measure and cut for the PDS Light. We recommend measuring and cutting on-site instead of having this product custom cut from the manufacturer. Cutting the PDS Threshold is simple as the material is made from a soft aluminum that can be cut by most saw blades.
Each PDS Light ships with the required fasteners along with full installation instructions from the manufacturer. A brief description of the installation can be found below.
The PDS Light is designed to install over the top of the existing door stops. Without installing over the existing stops, the profile of the PDS Light is too thin to seal the perimeter gap. The included fasteners screw into slotted holes allowing for easy adjustment from side to side if the door is bowed or uneven from top to bottom. The 1/4" foam should be compressed up to 1/8” for proper deflection. After installation is complete, the included cap cover is used to cover the fasteners. Make sure the seals are set in their final position before installing the cap cover as it is very difficult to remove without damaging the finish. Replacement cap covers are available if needed.
Our independent sound tests have shown the PDS Light to perform better than, or at least as well as, even the larger perimeter door seals like our PDS Heavy and other comparable products. We have found in our own testing that the size of the perimeter door seal is not crucial. The important attributes are the ease of installation, quality of the foam or rubber in the seal, and the ability to have the seal come in full contact with the door along the entire perimeter door seal.
