Automatic Door Bottom - Heavy Duty - Anodized Aluminum

Description: This automatic door bottom is specifically designed to create the best sound seal possible for normal sound levels. The aluminum casing is fitted with a self-extinguishing, closed-cell sponge neoprene or solid neoprene insert which serves as its primary seal. Additionally, the interior of the aluminum anodized casing is fitted with rubber for extra protection.Sponge Neoprene vs. Solid Neoprene: Both seal materials have high sound control properties and are very durable. However, solid neoprene will hold up longer over the years and should be used when applied to high frequency traffic or rough floor surfaces, such as concrete. This product is available as a surface mounted or semi-mortised application, as shown in the illustrations. It is non-handed and can be applied directly over the floor surface or above a doorway saddle, though a saddle is recommended for higher sound control (a saddle is highly recommended when applied over a carpeted area). Available in three anodized finishes and length is custom cut to size, up to 60". Installation screws and instructions provided. How it Works:This product utilizes a concealed flat spring mechanism which is activated by the pressure of closing the door (The brass nut at teh head gets pushed in by the door jamb, which lowers the seal). The high quality neoprene rubber seal drops, filling gaps up to 1”, upon the closing of door to create a tight seal and raises up automatically when the door is opened to ensure smooth door operation. Our door bottoms have been tested through 5 million cycles and provide the same excellent quality as our mortised automatic door bottom.Automatic Door Bottoms can be trimmed on the field up to 3-6", depending on the size ordered. Note, For maximum sound contrtol, we recommend keeping the gap between door and floor at no more than 3/8". Larger gaps can be treated with a door saddle or an added wooden strip to the underside of the door.Please Note, images are for illustrative purposes only. They are not actual photos. Therefore, actual color may vary slightly and size may be enlarged to show detail. Launching a Full Soundproofing Project:Doors are a significant weak link in any soundproofing project. The first issue with doors are the many air gaps around the door bottom and jambs. Proper sealing of doors are a must in any soundproofing project. This can be achieved by using automatic door bottoms and door gasketing.The second issue is the gap between the door frame and the drywall. Remove the door molding and stuff the gap with soundproofing rubber and caulk all gaps with an acoustical caulk.Finally, the door panel itself is the culprit as it is 1 single layer. Be sure to use a solid wood door (not a hollow core door). Then install a layer of 1/2" Medium Density Fibreboard (MDF) directly onto the door with Green Glue Damping Compound in between. MDF can be routed and painted beautifully. (If the looks of the door are not an issue you can use drywall or plywood).
