Zip-UP Terms:

Wall Trim -  The “E” shaped trim that attaches to the walls or joists around the entire periphery.
Main Rail - These are the mounting pieces that will run the length of your deck attached to the furring strips.
Panel - Refers to the show surface of your Zip-UP UnderDeck™ System.
Seam Trim - This is the piece that allows for the extension of your UnderDeck application by capping the ends of Main Rails that do not end at Wall Trim. The next section is installed the same as the first.
Pitch Rail - Pitching Rails are used to slope your entire under deck system in the direction of your gutter. They come in 1 inch and 1/2 inch profiles and are stacked incrementally to provide good pitch.

Planning Your Ceiling:

You will want to make sure that your ceiling is centered such that you do not end up with a very small panel on either side of your deck. Measure your deck width to start. Since the center of Main Rail to center of Main Rail dimension is 12 1/8 inches, you will need to divide the deck width by this number to derive the amount of panels you need. If Your deck is longer than the length of panels available, you will need to plan for a seam. You can start from the center of your deck and work to the sides, or you can start from one side and work across the deck to the other side.

Estimating Materials:

To estimate your materials you will start with the Wall Trim. Sum the lengths of the sides of the deck and divide by 12 feet. Round up to the nearest whole number for the total number of Wall Trim needed.

The number of Panels will be derived from the width of your deck, taking into consideration your layout calculated in the previous step.

The amount of Main Rails for each section equals the number of Panels minus one. If your deck is longer than the length of Panel available, you will need to determine how many seams are required.

The amount of Seam Rail you need is based on the width of the deck and the number of seams needed.

Example A: A 12' x 12' Deck requires (4) 12' Wall Trim, (12) 12' Panels, and (11) 12' Main Rails.
Example B: A 24' x 24' Deck requires (8) 12' Wall Trim, (2) 12' Seam Trim, (24) 12' Panels, and (23) 12' Main Rails.
