What are the Parts of a Window Screen?

Before you begin, it’s helpful to familiarize yourself with the parts of a window screen. A typical screen consists of a frame, mesh, and spline.

Frame

The frame is usually made of wood or aluminum and fits into your window’s opening.

Mesh

Mesh is the material that stretches across the frame, keeping bugs out and allowing air to pass through. It’s inserted into the frame’s groove or channel, which the spline holds in place. Mesh is usually made of fiberglass or aluminum and is available in different sizes and colors.

Spline

The spline is a rubber tube that fits into the frame’s groove, securely holding the mesh in place. The spline’s diameter varies depending on your groove’s width.

What Tools Do You Need to Replace Window Screen Mesh?

You’ll only need a few basic tools to replace a window screen, like scissors, a screwdriver, a utility knife, and a spline tool.

Scissors

You’ll need scissors to cut the screen to its required size.

Screwdriver

You’ll need a flat-head screwdriver to remove the old spline and push the new spline into the groove.

Utility Knife

Once installed in the frame, you’ll need a sharp utility knife to trim away the excess mesh.

Spline Roller Tool

A screen roller, also called a spline roller, is a simple tool with a wheel on each end. The tool rolls along the spline, pushing it into the groove.

What Type of Mesh Should You Use?

Window screen mesh or fabric comes in various materials, such as fiberglass or aluminum, and sizes to fit almost any window or door opening.

Aluminum Screen

When it comes to versatility, aluminum screen is a top contender. It’s sturdy, resistant to sagging, and less noticeable than other screen materials. However, aluminum is prone to creasing, and once it’s creased, it’s there forever.

You can choose from a shiny metal color or charcoal when buying aluminum screen.

Fiberglass Screen

Compared to aluminum, fiberglass screen does not crease and is easier to install. However, as it ages, I’ve noticed that it can fade, sag, weaken, and tear easily.

You can buy fiberglass screening in gray and charcoal, and it’s also available in a nearly invisible version and one that prevents tiny insects from squeezing through the holes.

Pet Screen

If you’re a pet parent, consider using pet screening that can withstand a pet’s weight and claws without being damaged.

For example, my friend Linda’s cats like to climb, so I used a pet-resistant mesh on the screen door I made for her.

Solar Screen

Solar screens significantly reduce the amount of heat entering your home, leading to cooler rooms and lower air conditioning bills. Solar screens also protect your floors and furniture from fading caused by the sun’s damaging UV rays.

What Size Spline Do You Need?

Once you decide what screen type to use, the next step is figuring out what size spline you’ll need to attach the mesh to your frame.

Spline is available in various sizes like .125″, .140″, .160″ and more.

To determine the right spline size for your project, you can either measure your old one or bring a piece to the hardware or home improvement store and match it up to the new spline.

I’m using .125″ spline in my wood window screen frame for this tutorial.

Window Screen Replacement Kits

You can purchase window screen mesh, spline, and a spline roller tool separately, or you can buy all of them together in a window screen replacement kit.

A window screen kit is an excellent place to start if you’ve never replaced a screen.

Before buying a kit, check that it contains enough screen to fit your frame’s opening and the right spline size for your frame’s groove.

Step 1. Remove the Old Screen

First, place your screen on a flat work surface. Then using a flat-head screwdriver, carefully pry the old spline out of the groove and remove the screen.

Step 2. Roll Out the New Window Screen

NOTE: For the best camera angle, I’m using photos from two screening projects – one with a red frame and one with a white frame.

Unroll your new screen material onto your frame, making sure it’s a few inches larger than the opening on each side, then use scissors to cut it to length.

Using my Kreg Workbench Clamps, I gently clamped the mesh to the frame while installing it to ensure a tight and wrinkle-free finish. You could also use spring clamps instead.

Step 3. Install the Spline

To begin, position the end of the spline into one corner and use a flat-head screwdriver to push it into the groove.

With one hand, gently stretch the spline while using your other to apply downward pressure on the spline tool. Roll it back and forth, pushing the spline into the groove until you reach the corner.

📝 NOTE: You may have to temporarily remove or reposition the clamps to continue installing the spline.

Using a flat-head screwdriver, push the spline into the groove on the next side.

Continue installing the spline around the perimeter of the frame until you reach the end.

Step 4. Remove the Excess Screen Material

When you reach the last corner, cut away the excess spline with a utility knife.

To remove the excess mesh, place the utility knife’s blade between the intersection of the spline and the groove and carefully trim the screen away.

Repeat this process on each side until the excess screen has been removed.
