SECTION 12: Side Wall Installation - Straight & Gabled Rooms

Note: For side walls on curved eave sunrooms refer to Section 14.

Note: Most sunroom side walls are installed after the installation of the WeatherGuard or glass roof. You may install the side walls before the roof only on rooms with straight or gable WeatherGuard roofs. Simply install the walls before the header beam (see below).

12-1. Measuring and Cutting the HeaderBeam
The header beams will arrive in stock lengthsand will need to be cut. Measure the lengthfrom the edge of the roof attachment channelto the inside corner of the front wall justbelow the roof (Figure 12.1). This will be the cut length for the header beam.

Note: On straight eave rooms, cut a 2-1/4”
x 3/4” notch (Figure 12.2, Detail “A”) to allowthe header beam to sit flush with the roof
panel. The end of the header beam will alsoneed to be cut at an angle to fit tightly againstthe house wall.

Note: On gabled rooms, cut a 2-1/4” x 1/2”
angular notch (Figure 12.2, Detail “B”) toallow the header beam to sit tightly againstthe roof attachment channel.

12-2. Installing the Header Beam

Slide the header beam over the side wall attachment channel and secure it at the junction of the screw guidelines with a #8 x 1/2" tek screw on each side (Figure 12.3). Line up the inside of the header beam with the outside
edge of the front wall. The header beam should be directly above the bottom track. Temporarily secure theheader beam to the roof panel or roof rafter from the underside with #8 x 1/2" tek screws.

Note: If there is a door in the side wall, refer to the Door Installation in Section 15.

12-3. Preparing the Side Wall Modules

A. The wall modules for the side wall room are individually numbered and will correspond with the module numberslisted on the CThru room layout sheet. Refer to Section 8.1A to help identify the modules.
Note: When placing modules in the bottom track, make sure the weep holes on the windows are facing outward.

B. On concrete foundations and deck applications, the foundation may not be level. See Section 8.1B on trimmingthe solid material on the kickplate to compensate for a sloped foundation.
Note: The tops of the side wall modules on gabled roof rooms should not need to be trimmed. They should allarrive the correct height. Proceed to Section 12-5.

12-4. Measuring the Correct Module Height (Straight Eave Rooms Only)

The side wall modules will all arrive at the same height. Straight eave rooms will need the tops of the transoms
trimmed to conform to the slope of the roof. Check the CThru Room layout sheet to see where first side wallmodule will be placed in relation to the house wall. Beginning at this point, take the vertical measurement fromthe inside lip of the bottom track to the bottom of the header beam and add 1" (Figure 12.4, Detail "A"). Usingthe width of the module as a guide, take this same measurement on the side wall where the opposite end of thewall module would sit. Again, add 1" to this measurement (Figure 12.4, Detail "B").

Note: For side walls with glass transoms, the modules will arrive with "open" window frames. Follow the same procedure as if the module has a solid transom. The glass installation will be covered in Section 13.

12-5. Cutting and Placing the Side Wall Modules

Transfer this measurement to the wall module and chalk a line along the slope of your cut. Use a 10" circular saw to cut the module to the correct height. Once the correct slope is cut, the module can now be placed intothe wall. Lift the module, tilt it slightly, and slide it into the header beam. Return the module back to perpendicular, and rest it into the bottom track. If the module does not clear the bottom track, remove more material from the top of the module.

Note: Repeat these steps until all of the wall modules have been placed.

Note: Do not fasten the wall modules at this point. You may need to slide each module back and forth to placethe subsequent modules.

Note: If the outside fin of the side wall channel was cut (in Section 7-2), it may now be re-attached using #8 x5/8” tek screws.

12-6. Adding Solid Fill

The CThru room layout sheet will note if the ends of the side wall require solid fill. If the side wall requires solidfill, refer to the layout sheet for the cut size of the solid fill. You can double check this measurement by measuringfrom the inside of the "H" channel of the module closest to the house to the inside of the wall attachment channel
for the width, and the height of the module for the height (both sides may be slightly different to account for theslope of the foundation). Cut the solid material and place it on the sides of the side wall (Figure 12.5). You may
need to slide the modules back and forth to fit the solid fill closer to the house wall. The solid fill at the front of
the sunroom should reach the inside edge of the front wall and will be concealed by the inside and outside
corners.

IMPORTANT! THE MODULES AND THE WINDOW FRAMES MUST BE PERFECTLY LEVEL AND PLUMB
IN ORDER FOR THE WINDOWS TO OPERATE PROPERLY. BEFORE PROCEEDING, TEST EACH MODULE
WITH THE WINDOW SASHES TO MAKE SURE THE WINDOWS FIT AND LOCK PROPERLY.

12-7. Fastening the Wall Modules Together

You will be attaching the modules together by the utility mullions affixed on either end of each module. Be sureto mate a male and female utility mullion together for a proper fit. A sheet metal screw or Pop rivet will be needed
every 24" to attach both sides of the utility mullion together. Fasteners should be placed to the inside of the UtilityMullion, thus allowing the fasteners to not be exposed. Vinyl cladding will be added on top of the utility mullion(on Omega rooms only), and an aluminum cover plate for Alpha systems during the Electrical Installation section
of this Sunrooms-manual.

12-8. Fastening the Wall Modules to the Bottom Track and Header Beam

The modules will be fastened with sheet metal screws at the base where the vertical mullions and bottom track
intersect. Use the guide line in the bottom track to place the screws. Fasten two sheet metal screws per utility
mullion connection at the base on the room's exterior. Repeat this process at the top of the modules where thevertical mullions and header beam intersect

12-9. Cutting and Attaching the Outside Corner
The outside intersection of the front wall and side wall will be covered with an outside corner extrusion. The outside corner will arrive in stock lengths and will need to be cut to size. Measure the height of the corner fromthe foundation to the bottom of the roof. Note that on a straight roof, the side wall half of the outside corner willbe cut at an angle to conform to the slope of the roof. On the gable roof, the front wall half of the outside cornerwill be cut at an angle to conform to the slope of the roof. Find this angle and cut the outside corner to length. Fasten the outside corner to the header beam and the bottom track using #8 x 1/2" tek screws.

12-10. Cutting and Attaching the Inside Corner
The inside intersection of the front wall and side wall will be covered with an inside corner extrusion. The inside corner will arrive in stock lengths and will need to be cut to size. Measure the height of the corner from thefoundation to the ceiling. Cut the inside corner at an angle to conform to the pitch of the ceiling. Fasten the inside corner to the header beam and the bottom track using #8 x 1/2" tek screws.
