Casement windows – hinged on the side and opened with a crank – are popular in many US homes. But fitting a screen can be tricky because the mesh must not interfere with the crank handle or the outward swing. This guide covers three effective solutions.

The Challenge

Traditional frame screens mounted on the interior can block the crank or be pushed outward. Exterior screens are unsightly and hard to clean. You need a solution that stays clear of the operating mechanism.

Option 1: Adhesive Velcro Screens (Best for Renters & Simplicity)

Stick hook‑and‑loop tape directly onto the interior window frame. The screen presses onto the tape and does not touch the crank. When you want to open the window, the screen stays attached; the window opens outward. It's removable and leaves no damage. Ideal for 90% of casement windows.

Option 2: Retractable Screens (For Frequent Use)

A cassette mounted at the top or side of the window. Pull the screen down/ across when you need protection; roll it up when not. The cassette sits flush, and the screen does not interfere with the handle. Perfect for kitchens or living rooms where you open the window often.

Option 3: Custom Fixed Frame (Slim Profile)

A very low‑profile frame screwed into the window opening with the mesh placed as close to the glass as possible. The crank handle must clear the frame – measure carefully. This is the most durable but least flexible option.

Installation Tips

For adhesive screens, clean the frame with alcohol first. For retractable systems, you'll need a screwdriver and spirit level. Fixed frames require drilling and a spline tool.

Conclusion

Adhesive velcro screens are the easiest and most effective solution for casement windows. They cost little, install in minutes, and allow full window operation. MBORMC makes custom adhesive screens to your exact measurements.
