3-Sided Exposure - Flat Roof
For Wrap Around Porches, Imagine Another Side and Use These Concepts
About the Diagrams
Your project will consist of 1 or more panels. The configuration diagrams to the right demonstrate general concepts and possibilities from an arial view (plan view or satellite view). You can create any configuration of your choosing using these concepts. Download Worksheet
When You Will Need Assistance
Most clients order directly online, however, If heights vary by more than 2" (like sloped rooflines)
or if your panels require notches to avoid obstacles, we will need to assist you. How to prepare.
Principles to Remember
Identify a clear path and then measure along that same path
It is common for a few inches of panel to hang off end of track to snap
Measure twice and check your math
Velcro attachment is side mounted while tracking attachment is undermounted
Never use a magnetic connection at a corner (weak hold)
Therefore a panel MUST straddle an irregularly-shaped CORNER column
If corner columns are regular (like a 4x4 post), take an exterior path and break panels snapping them independently to the outside faces of corner posts
Be sure to order tracking hardware and fasteners separately
Important Measurement Adjustments
The sum width of all your panels needs to be wider than your actual exposure for overlapping magnetic doors or overlapping a structural surface (like a wall or column) and a little more so that you can have a relaxed fit.
It all depends upon how you measure. Did you measure just the exposed opening or did you overlap some surface when you measured already accounting for overlap? Use your good judgement. Curtain projects that are too narrow, don't work. Curtains that are too wide are sloppy loose and unstable in the wind. Hint: It is easiest to plan all your panels first using exposed widths (to get the math right) and then make all adjustments at once.
Width Adjustments - Assuming you measured just the exposure without any overlap
Automatically add 2-inches per panel regardless of width, then
Add another 1-inch per panel for EACH edge that will snap to some surface
Subtract 1-in for EACH edge connecting a Stucco Strip, and ignore width of stucco strip
For Tracking Attachment: Add another 1-in per 10ft of panel width for relaxed fit.
For Velcro Attachment: Add another 1-in per 20ft of panel width
Height Adjustments - These adjustments will give you a 1" overlap with floor
Tracking - Measure from underside of track mounting surface to floor (NO adjustments)
Velcro - Add 2" to height of just the exposed "hole" for 1" overlap top and bottom
If height of a given panel varies by 2" or less, use taller height
What is a Stucco Strip Again?
Remember from Step 3 that a "stucco strip" is just a mini 3 inch wide panel made of webbing material used when you do not want to "unsnap" as you draw your curtains improving usability.
One edge is snapped to a structural surface and the other edge forms a magnetic connection to a panel.
Configuration Concepts For Planning
10 Principles To Remember
1. Most Velcro® tape attached orders use an outside hang because you can utilize the natural structure of support columns and any railings you may have while maximizing usable porch space.
2. Tracking attachment commonly uses an inside hang especially for curtain panels that turn a corner because they swag prettier. Think about how your curtain will look both open.
3. Side bindings that meet at a support column both hide the seam and can be secured to the support column using marine snaps.
4. Curtain panels need to be a bit wider than your actual exposure for protective overlap.
5. Do not end panels at irregularly-shaped CORNER columns. Instead, let the panel turn the corner and seal to another panel using magnets. Panels can meet at non-corner irregularly shaped columns.
6. You should try to minimize the number of panels as the curtain is very pretty when it is seamless and you have less to seal. One or two exits are generally sufficient and you'll save on cost.
7. Masonry such as brick or stucco, can stress the netting fabric, so begin and end panel at masonry support columns and walls so only the sturdy binding can is directly exposed to masonry.
8. Consider right-angle straight tracks instead of curved track, if you plan to swag the curtain to a particular corner where the curtain panel turns that same corner.
9. The most overlooked items when ordering are fiberglass rods (2 per panel) and marine snaps.
10. Obstructions such as rain downspouts can be avoided with a panel split on either side of the obstruction.

A regularly shaped column has a perfectly straight edge from ceiling to floor. A 4in x 4in support post or, a 2ft x 2ft square-base, stucco column would be examples of regularly shaped columns. Regularly shaped columns are easy to snap to since the column has a straight continuous edge. If there are no obstructions, the best path for regularly-shaped columns is a path exterior to the columns, but to end a panel and start a new panel at corners. Each panel snaps independently to either side of a regularly shaped corner column.
Irregularly-shaped columns do not have a perfectly straight edge from ceiling to floor. Examples are fluted, spindled, tapered, or bungalow-style columns. Because the straight edge of the curtain will not match the non-linear edge of the column, you cannot achieve a good seal by snapping. For CORNER columns, let the panel "straddle" the corner with a path inside the columns. In the next step, we'll show you how th "pinch" the center of the panel to a corner column using our elastic cord.
Hint: If you have a panel split at an irregular column that is NOT a corner column, you can achieve your seal with a magnetic connection and then snap one panel to the irregular column for stability.
Almost Regularly-shaped Columns
You can treat these as regular columns if you take a path on the exterior side of these columns allowing the panels to run past the columns (recommended). Remember that if you are taking an outside path to "break" panels at corner columns rather than straddling a corner with a single panel. When these decorative caps have a thin profile with very little deviation from a straight edge, you can drape over the caps to snap. Open the diagram to see another trick.
You may also treat these as irregular columns and take a path interior to these columns, in which case you would not try to seal to a corner column. Instead, straddle the corner and use elastic cord (described in Step 4) to pinch center of straddled panel to corner column.
