Installation Guidelines for RV Noble® Sheet Glass Sidewalls
The following installation guidelines represent RV industry standard installation practices for “free-hanging” exterior
sidewall panels:
1. String a line on the exterior of the frame studs from end-to-end to ensure straight walls. Straighten any studs that are
out of alignment.
2. If using aluminum or steel studs, lightly grind the studs to scuff the surface to improve the strength of the glue bond.
Also, grind down any large bumps. (The glue manufacturer will have preparation requirements for their glue system)
3. Wipe all studs (aluminum or steel) with a 99% alcohol solution.
4. Wipe all studs with an adhesive prep solution (Sika Corporation makes a prep solution specifi cally for their Sikafl ex®
adhesive).
5. Cover all studs with Sikafl ex 221. You may stop coverage a few inches from the edges where screws will be applied.
6. If a hoist is not available to lift sheet glass on the wall and hold until screwing panel to wall, then use a screw block
on the lower edge of unit. Set wall on blocks without touching the adhesive. Slide into position, and then push the
remainder of panel onto the wall frame.
7. Screw across the top of the panel beginning in the center and screwing to the ends of the unit. Be sure to use
self-tapping screws or pre-drill the holes. Do not drive the head of the screw into the glass surface, unless a pilot hole
has been rounded out larger than the head of the screw. Failure to do so may result in the glass cracking and the
crack lengthening with stress from the unit moving. Please pre-drill rather than using self tapping screws.
8. After the top is screwed, release the hoist (or unscrew the blocks on the bottom) and let the panel hang free allowing
the weight of the panel to fl atten the wall.
9. Run braces across the panel from top to bottom every two feet. The brace should have a chamber to force
pressure against the surface of the wall. Wider coverage on the bracing ensures uniform pressure of the panel to the
studs. Put the braces on an angle to allow multiple stud coverage with the same brace. Keep braces on overnight or
as long as recommended by Sika Corporation.
10. Route around door, window, and edges. Make sure the router does not chatter and do not route too fast. This will
eliminate potential glass cracking when routing.
11. The wall panel may be screwed around window and door openings, along the ends, and the bottom. Be sure the
screwing procedures mentioned above are followed.
