Best Practices for Installing Magnetic Screen Doors on Arched and Irregular Shape Openings

Understanding Arched and Irregular Openings

Types of Non-Standard Shapes

• Full Arch: Complete semicircular top
• Segment Arch: Partial arch (less than semicircle)
• Eyebrow Arch: Wide, low curve
• Gothic Arch: Pointed top
• Trapezoidal: Angled sides (wider at top or bottom)
• Rounded Corners: Soft curves at corners instead of sharp 90° angles
• RV Doors: Curved, non-standard recreational vehicle openings

Why Standard Screens Fail These Shapes

A standard rectangular magnetic screen door simply cannot fit an arched or irregular opening. You'll always have gaps at the curves, ugly overhangs, or a screen that's too small to provide any real coverage. Only a custom screen door by dimensions can match your exact shape.

How to Measure Non-Standard Openings

For Arched Doorways:

1. Measure the Width
At the widest point (usually the bottom), measure left to right at three points: top, middle, bottom. Use the smallest measurement.

2. Measure the Height
From the floor to the highest point of the arch. Do this at left, center, and right positions.

3. Measure the Arch Curve
This is the critical part. Use a flexible measuring tape or a piece of string:

• Run it along the curve of the arch from left to right
• Note this "arc length" separately from the straight width
• Take multiple measurements along different points of the curve

4. Create a Template
For complex shapes, create a template using cardboard or butcher paper cut to match your exact opening shape.

5. Take Photos
Photograph the opening from multiple angles—front, side, and close-ups of any unusual features. These help ensure accuracy.

For Slanted/Trapezoidal Openings:

1. Measure all four corners individually
2. Note which corners are higher/lower
3. Measure the maximum width and height
4. Measure at multiple points along the slant
5. Measure the frame depth at multiple points

For RV & Camper Doors:

1. RV doors often have curved frames—measure the curve carefully
2. Note any irregularities in the frame
3. Measure depth at multiple points
4. Account for vibration and movement when selecting adhesive

Installation Best Practices for Arched and Irregular Screens

Surface Preparation Is Critical

Irregular shapes create more surface area for adhesive. Clean thoroughly:

• Remove all old adhesive residue
• Clean with rubbing alcohol
• Ensure surface is completely dry
• For RV doors, also clean any curved surfaces especially well

Work in Sections

For arches, install the straight sections first, then work into the curve:

• Top-down approach works best
• Press firmly along curves to ensure adhesive contact
• Use painter's tape as temporary guides
• Don't rush the curve sections

Dry Fit Multiple Times

• Dry-fit without adhesive first (multiple times if needed)
• Hold the custom magnetic screen in place and test the fit
• Adjust before committing—the adhesive is forgiving but not infinitely adjustable
• For French doors with arches, check that the magnetic closure works at the meeting point

Account for Temperature Changes

Temperature affects adhesive bonding:

• Install in moderate temperatures (50-80°F)
• Allow extra cure time before full use
• Check the seal after the first week
• For RV doors, check adhesion more frequently due to vibration

Common Mistakes to Avoid

1. Guessing the shape — Always measure, never assume
2. Ignoring frame depth — Depth matters for adhesive contact
3. Rushing surface prep — Clean thoroughly or the screen won't stay
4. Installing in wrong weather — Extreme temperatures affect adhesion
5. Not checking after first week — Settling can affect the seal
6. Skipping the online configurator — ZOORSCREEN's tool helps catch measurement errors
