SECTION 4: Attachment Channels & Accessories
Identifying and inspecting Materials
Your room will be attached to the existing structure and foundation with a series of attachment channels. The following is a brief list of the attachment channels needed and the items required for their installation:
1. Bottom Track (Figure 4.1): affixed to the slab or deck. The walls of the sunroom will rest in the bottom tracks.
2. Wall Channel (Figure 4.2): affixed to the existing structures's walls. Used to attach the side walls of the room to the structure.
3. Roof Attachment Channel (Figures 4.3 & 4.4): affixed to the exiting structure above the wall channel. Used to attach the roof panels or sunroom rafters to the existing structure. Note that different roof attachment channels are used to attach the Weather Guard solid roof (Figure 4.3) and beam glass roof (Figure 4.4) to the existing structure.
4. Anchors: When attaching to wood applications, use 3-14g SST wood screws
5. Anchors: When attaching to concrete applications, use Hilti 3/8" Kwik Bolt II or approved equals (refer to ICC-ES Report #4627
6. Sealants: caulking, silicone, etc.
7. Metal flashing may also be required. See roof attachment (Section 5) for flashing details. Additional flashing may also be needed at the bottom track and wall channel.
8. Carpenter's pencil and chalk line.
Once the proper materials have been identified, inspect that they are free from damage. Many of C-Thru's extrusions will contain a screw guide. The screw guide is a line etched into the extrusions that can be used as a guide for fastener placement.
