SECTION 14: Side Wall Installation - Curved Eave Rooms

14-1. Installing the First Module on the Side Wall (Curved EaveRooms Only)

The side wall module closest to the curve will be installed first. The
module will arrive with a female channel on one side toward the
front wall, and an open transom frame with half of a utility mullionon the other side (Figure 14.1).

The open transom side will be cutand attached to the roof rafter using a small section of "C" channel.

Note: The front of the side wall module will begin at the inside cornerof the bottom track.

A. Measuring and Trimming the Open Transom
The first step is to trim the leg of the open transom to fit underneaththe roof rafter beam. Using the width of the wall module as a guide,
find the point on the side wall where back leg of the wall module willsit. Take the vertical measurement from the inside lip of the bottomtrack to the bottom of the header beam and deduct 1/8" (Figure14.2). This leg will be cut at an angle to conform to the slope of theroof.

B. Marking the Roof Rafter
Temporarily place the wall module in the bottom track, and slide itinto the proper position. The front side of the wall module should
line up with the inside corner of the bottom track. Make sure the
module is plumb and level. Place a mark on the roof rafter beam
where the inside edge of the utility mullion and the roof rafter intersect.

D. Fastening the Wall Module
Slide the wall module back into place so that the front of the module is at the inside corner of the bottom track.
Make sure the wall module is plumb and level. Fasten the bottom of the wall module with one #8 x 1/2" tek screwon each side at the junction of the utility mullion and the bottom track, and at the junction of the female extrusionand the bottom track. Fasten the top of the wall module with two #8 x 1/2" tek screws on each side at the junctionof the utility mullion and the "C" channel (Figure 14.4).

14-2. Glazing the Curved Glass (Single Glass Only)

Note: C-Thru does not supply the transom glass for the curved eave sunroom at the time of shipment due to thefact that you set the pitch of the roof on site. You will need to make a cardboard template and order the glassfrom C-Thru or a local glass supplier (see glass compatibility chart for comparable glass types).

A. Making a Template for the Curve-Cut Glass (Single Glass)
The curved section of the glass will sit inside the outer groove of the roof rafter, so the template should be cutapproximately 1/4" larger than the opening around the radius (Figure 14.5). Make sure the bottom edge of thetemplate sits flush with the inside edge of the fixed window jamb.

Note: The fixed window jamb on the module contains a raised "bump out".
The glass will be attached to this portion of the fixed window jamb with glazing tape (Figure 14.5).

B. Installing the Curve-Cut Glass (Single Glass)
Once the glass is cut, place 1/2" thick glazing tape on the raised "bump out" of the fixed window jamb, and removeits protective film to expose the adhesive. Tilt the glass slightly and insert the curved side into the outer groove
of the roof rafter. The square end of the glass should fit snugly against the lower portion of the fixed windowjamb. Push the glass so it seats firmly against the glazing tape. Seal the inside and outside of the radius (where
the glass meets the rafter) with a bead of silicone. Cut and install glazing clips on the fixed window jambs.

14-3. Glazing the Curved Glass (Dual Glass Only)

A. Fabricating a Glazing Bead (Dual Glass Only)
Cut and bend a piece of inside corner extrusion to conform to theinside radius of the roof rafter (Figure 14.6). Secure this inside
corner extrusion to the rafter, matching it to the plane of the fixedwindow jamb, and secure it to the roof rafter with Pop rivets or #8x 1/2" tek screws.

B. Making a Template for the Curved Glass (Dual Glass Only)
The curved section of the glass will sit flush with the roof rafter,
and the square edge of the glass will sit flush with the inside edgeof the fixed window jamb. Make a cardboard template and sendit to C-Thru or your local glass supplier.

C. Installing the Curve-Cut Glass (Dual Glass Only)
Once the glass is cut, place 1/8" thick glazing tape on the raised"bump out" of the fixed window jamb, and remove its protectivefilm to expose the adhesive. Insert the glass into the opening and press it firmly into the glazing tape. The square end of the glass should fit snugly against the lower portion ofthe fixed window jamb. Push the glass so it seats firmly against the glazing tape. Seal the outside of the radius
(where the glass meets the rafter) with a bead of silicone. Cut and install glazing clips on the fixed window jambs
(Figure 14.7).

14-4. Placing the Subsequent Modules

All subsequent modules will need to have their transoms trimmed and be attached to the roof rafter with a sectionof "C" Channel. Follow the procedure described in Section 14-1-A through 14-1-C until all of the side wall modulesare installed. Do not fasten the wall modules yet.

14-5. Adding Solid Fill

The C-Thru Room Layout Sheet will note if the end of the side wall requires solid fill. Refer to the layout sheetfor the cut size of the solid fill. You can double check this measurement by measuring from 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 the slope of the foundation).

The solid material may also be cut slightly shorter, as the wall channel allows for a degree of adjustability. Cutthe solid material and place it on the sides of the side wall.

Note: The solid fill may be a tight fit. You may need to cut the solid fill narrower and slide it into the attachmentchannel before installing the wall module closest to the house wall.

14-6. Fastening the Wall Modules

The wall modules will be joined together at the junctions of the utility mullions. Each "C" channel will be fastenedto two modules. See Section 8-4 on the procedure for fastening the utility mullions together.

14-7. Glazing the Transom Glass

The transom glass will be installed in the same manner as the glass for the first module. The only difference isthat there will be a fixed window jamb on three sides of the transom, instead of two. Follow the proceduredescribed in Section 14-2 (for single glass) or Section 14-3 (for dual glass) until all of the transom glass is installed.

14-8. 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 curve on the roof rafter. Fasten the outside corner to the front wall, side wall, and the bottom track using #8 x 1/2" tek screws (see Figure 14.8)

14-9. 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 end of the curved roof rafter. Cut the inside corner at an angle to conform to the pitch of theceiling. Fasten the inside corner to the header beam and the bottom track using #8 x 1/2" tek screws.

See Figure 14.9 for the completed curved eave side wall.
