For door soundproofing, a tightly sealed door is required. The Door Seal Soundproofing kit allows you to keep sound contained by incorporating a special high density acoustic felt for a tight seal around you door. To soundproof your door, simply install the felt in your door, apply the foam pads to the door hinges and secure the aluminum threshold for a tight fit. Installation requires using a 1/4 in. router or dado blade to cut a groove on all four sides of your door. The felt is then glued into place. |
