Sound Proofing - part 2

The installation of the sound proofing on the aft, port, starboard, and ceiling of the engine compartment is compete.  The work took more time than anticipated, but that is par for the course in the boat world.  I am pleased with the aesthetics of the sound proofing.  Between the white of the new bilge paint and the reflective silver color of the sound proofing panels, the engine room appears quite bright and smartly institutional.

The final paragraph of sound proofing part - 1 attempted to briefly describe the mechanical fasteners used to affix the sound proofing.  I fear my words fell short, and since a picture is worth one thousand words here is a couple of images to describe the process.

installing sound proofing mounting pins on the engine room access panel

  The mounting pins are available in self adhesive or screw on (pictured above).  Trusting the mechanical fasteners over the adhesive, the majority of the pins I used were the screw in type.  The self adhesive model proved essential in some of the hard to reach crannies of the engine room.

Once the pins are in place the pre-cut foam panels are pressed onto the pins.  The point of the pins easily pass trough the panel and extent out the face.   The pins are then cut flush to slightly proud of the surface of the panel.  Caps that grab the pins are pressed on to hold the panel in place.

The installation instructions mandated one pin for every square foot of panel and tape around the perimenter.  I used well beyond that number of pins in the hatches and on the ceiling.  The hatches required additional pins due to the inability to secure the perimeter of the panel with tape.  Gravity dictated additional pins in the ceiling.  I used far less than one pin per square foot on the port, aft, and starboard walls because many of the engine components attached to the walls and the tape around the perimeter of the panels serve to secure the sound proofing.
