Default Luxury Coach Engine Compartment Soundproofing

Luxury Coach Engine Compartment Soundproofing

These instructions are best suited for installing a 2" Vinyl Sandwiched Foam, and will also work for installing the heavier 2" Lead Foam which was used on many highend coaches and buses for years. You may be replacing damaged lead foam that is dangling down. The lead foam is great and probably the best product out there but not necessary. The db noise reduction of the 2" Vinyl/Foam is still superb, lighter, easier to cut and install. You can combine other products as noted below. If you decide to go with the product Sean (NewellCrazy) posted in the basement thread here: http://www.luxurycoachlifestyle.com/...nsulation.html, you can also double it up to get the thickness or install your own vinyl layers. If stalling the 1" product in a single layer and you want to pin, speed washer and cap it, you will have to cut all pins accordingly. After reviewing the information and pictures below, you should catch on as to how it's done. The only diagrams I could find were for a yacht engine compartment but the principle is the same.


[TABLE]
<tbody>[TR]
[TD="colspan: 2"] Step 1: Measuring and Making Patterns:
Measure inside surfaces to be soundproofed. Transfer measurements to materials or make cardboard patterns noting example: "Engine Bay Compartment Right Side" and so on... Be sure to allow for material thickness at corners. Double check for fit by placing cut patterns into enclosure. Top panel goes in first allowing the use of adjacent vertical panels for additional support at the outer edges of top panel.

Note: For larger installations, sheets of material may be joined together by applying spray adhesive to both exposed edges and butting together. Finish-off by applying seam tape to front and back surfaces.

For additional engine compartment soundproofing, you can use additional carpet Underlayment. Acoustic Carpet sound insulation Underlayment is an important part of a motor coach engine compartment soundproofing attenuation and insulation package..[/TD]
[TD="width: 50%"] Q. How many pin sets do I order? A. One pound per sq ft. vinyl/foam a minimum of 20 pin sets, a 2 lb per sq ft. vinyl/foam a minimum of 25-30 pin sets.[/TD]
[/TR]
</tbody>[/TABLE]
[TABLE]
<tbody>[TR]
[TD] [/TD]
[TD] Step 2: Layout and Cutting of Material:
Arrange patterns on reflective side of soundproofing insulation, nesting for best utilization of material. The silver facing side should face upwards for cutting. Using a sharp utility knife or a serrated knife, or table ban saw etc., carefully cut panels to contour indicated from patterns. Use firm steady strokes, holding blade sideways in vertical position with cutting edge at low angle to prevent tearing of material. Repeat cutting strokes until all material has been cut through. Install panels "Dry" to check for correct fits and allowances. Note installation sequence and repeat during final installation.[/TD]
[/TR]
</tbody>[/TABLE]
[TABLE]
<tbody>[TR]
[TD] Step 3: Installation of the Pins

Fasteners:

Now that the material is cut to fit, fasteners should be installed at this time. If you are using "Screw Fasteners" see step 6 for attachment and spacing. Use mechanical fasteners on all overhead surfaces as well as vertical surfaces to ensure backup in the event of adhesive failure. Fasteners should be permanently attached with screws, nails, staples, epoxy, etc., to overhead at the center, and additional fasteners approximately 1/2. the distance, along a diagonal to each corner. Use one fastener or more for each 2-3 square feet of surface, with fasteners spaced approximately 16 inches apart for the 2lb per sq ft. 20" apart for 1lb per sq ft. The same spacing holds true for "Screw-in-Fasteners".
To insure that you center the pressure directly over the pins, we suggest you use a clear plastic cup to push the pin through the vinyl/foam. If your using our PSA, once you've cut your panel to size then peal back 2" of protective coating so you can apply the soundproofing tape all around the panel, when completed then remove the remainder of PSA coating and affix to surface.


- If you are using "Screw-in-Fasteners" see step 6 for attachment and spacing.
Note: Installing top panel first allows the use of adjacent vertical panels for additional support at the outer edges of top pane.
[HR][/HR] If you're placing soundproofing against metal or fiberglass in your engine compartment , use 3M-5200 quick cure to secure our pins, takes 24 hrs to cure, you'll need approximately 1 pin 20" on center for 1lb per sq ft. 16" on center for 2lb per sq ft. View step # 1. Use 2" tape for 1/2" & 1" Vinyl/Foam & 4" tape for all other thicknesses[/TD]
[TD="width: 50%"] What you'll need using Vinyl/Foam because of the weight;For all 2# vinyl/foam place pins 16" on center
For all 1# vinyl/foam place pins 20" on center
For 2" -1-1/2" vinyl/foam use 4" tape to completely cover foam.
For 1" vinyl/foam use 2" tape.
1 Can of Adhesive spray; covers 54 sq. ft.

[/TR]
</tbody>[/TABLE]
[TABLE]
<tbody>[TR]
[TD] [/TD]
[TD] Step 4 - Sealing Exposed Edges:

Seal all exposed edges, wear and chafe points with Seam tape to prevent fumes, moisture, or other foreign matter from contaminating the soundproofing. Overlap approximately 1/2 inch on reflective foil facing, fold tape down over exposed edge of material and fold remaining tape onto rear surface. Work pressure sensitive adhesive onto reflective foil and on to foam by carefully rubbing entire surface of tape until maximum adhesion is obtained.[/TD]
[/TR]
</tbody>[/TABLE]
[TABLE]
<tbody>[TR]
[TD] Step 5 - Final Installation:

At this point, all panels should be trimmed for exact fit, with all exposed edges sealed and protected with tape, sequence of panel installation noted, mechanical fasteners in place, and all attachment surfaces clean and ready for application of adhesive.

You are now ready for Final Installation. Apply adhesive and install one panel at a time. Install top panel first. Caution: Take care to avoid injury from sharp projecting pins on hangers when pushing soundproofing into place. Following directions and precautions on can, spray two coats of adhesive (spray 2nd coat in opposite direction for best results) onto prepared (clean) mounting surface, allowing drying time between coats, and carefully apply a light coat of adhesive to back of soundproofing. When sufficiently tacky, accurately position and firmly press pan into place. Accurate positioning is critical - cement bonds instantly upon contact! Caution: Apply adhesive sparingly![/TD]
[TD="width: 50%"] Hanging pins, now is the time to use them. Install screw keeping with the same spacing that is in step 3. If you're affixing either vinyl sandwiched foam or a lead foam product to metal or fiberglass, use 3M 5200 quick cure to affix the pins. Allow 24 hrs to cure.[/TD]
[/TR]
</tbody>[/TABLE]
[TABLE]
<tbody>[TR]
[TD] Step 6 - Installing of Speed Washers Screw in Fasteners
Push speed washers onto projecting fastener pins until soundproofing is slightly compressed. Caution: Do not over compress soundproofing or tear reflective facing. When all speed washers are correctly installed, use a pair of wire snips to cut protruding pins approximately 1/8 inch beyond speed washer. See Step 3. Install protective caps when supplied. Recess pins 2-3" off corners 18" on center for 2lb & 20" for 1lb per sq ft.[/TD]
[TD="width: 50%"] Step 7 - Finish Taping of Seams and Joints:
Apply reflective seam tape to all exposed joints and corners, by accurately positioning centrally over joints, and firmly pressing into place. Rub entire surface until maximum adhesion is obtained.
[/TD]
[/TR]
</tbody>[/TABLE]
[TABLE]
<tbody>[TR]
[TD] Step 8 - Carpet Underpayments Options:

Carpet underlay materials are intended to be installed with the foam down against the deck or floor, and the vinyl barrier towards the carpet. Material that is installed upside down will not provide as much quieting as a properly installed sound insulation underlayment.

Having the carpet & engine area noise insulated, will give you optimum noise attenuation.
[/TD]
[TD="width: 50%"] Step 9 - Compartment Headliners Options:

Headliners may be installed directly to any surface. In some instances such as the overhead, it may be desirable to mount the material to thin panels which may be blind fastened to the overhead beams or structure with interlocking, removable fasteners such as head-lock pads. With a panel system, the material may be wrapped around to the back of the panel. The removal of the foam from the material that is to be wrapped around the panel edge will result in a sharper edge. This may eliminate the need for wood trim work at seams or edges.

These materials should be handled carefully during the installation to avoid any sharp folding of the vinyl back on ' itself, which may result in creasing of the material. If a crease is inadvertently made in the vinyl, it may be relaxed with heat when in place. If not yet installed, pull slightly during placement, to stretch the wrinkle out of the material.

Larger sections may be laid into place after cutting and by carefully folding back the material onto itself one half at a time to be bonded into place.Spray glue on both the foam and the surface to be covered. Always maintain a radius where folded, especially on the second half bond as the first half bond ends abruptly and may cause creasing if the material is pulled back against it. A cardboard tube may be of assistance on flat areas in this process.
