Window and door screens keep bugs and debris out while still letting in fresh air. Choosing the right screen can make your home more comfortable and look nicer, too.
When you’re picking a screen, it’s important to think about things like the mesh size, strand size, and spline size. To get the best fit and performance, you’ll need to measure your windows and doors carefully and choose the right materials.
This guide will walk you through everything you need to know about screen sizes, materials, spline dimensions, and how to choose the right screen for your needs.
Demystifying Screen Mesh Sizes and Materials
When you’re shopping for screens, it helps to know the lingo. Here’s a breakdown of screen mesh sizes and the materials they’re made of.
Screen Wire Size: Mesh Size and Strand Size Defined
Screen wire size has two components:
- Mesh size refers to the number of openings per square inch. The mesh size determines what can pass through the screen. It also affects how rigid the screen is. A higher mesh count means smaller openings, which is helpful if you want to keep out small insects.
- Strand size (wire gauge) refers to the thickness of the wire. A larger strand size means the screen is stronger and can cover wider spans without sagging. Strand size matters when you want a durable screen that can withstand damage.
Common Screen Materials
Screens are made of many different materials, including:
- Fiberglass, a common and affordable material that provides basic insect protection.
- Aluminum, which is more durable and long-lasting than fiberglass. It’s a good choice for areas that see a lot of wear and tear.
- Vinyl-coated polyester, a very durable material that resists stretching and sagging. It’s often used in pet-resistant screens.
Specialized Screen Types
Some screens are designed for specific purposes:
- Pet screens are made to withstand damage from pets. They’re made from strong, durable materials like vinyl-coated polyester.
- No-see-ums screening has an extra-fine mesh that keeps out even the tiniest insects. It’s essential in areas where small, biting bugs are common.
- Solar screening blocks sunlight and reduces heat gain inside your home. It can lower your energy costs and protect your furniture from fading.
Choosing the Right Screen Spline
Replacing window or door screens can be easy, but it’s important to get the right size of screen spline. Spline is the vinyl cord that holds the screen material in place within the frame. If you pick the wrong size, the screen might come loose or sag.
Understanding the Role of Screen Spline
The right spline size is key to a successful screen installation. Choosing the right size will prevent the screen from popping out or drooping.
Measuring Spline Size
Spline is measured by its diameter, which tells you how thick it is. To find the right size, measure the width of the groove that holds the spline on your screen frame. You can use calipers or a ruler to get an accurate measurement.
Spline Size Selection
You’ll want to match the spline size as closely as possible to the width of the groove. That way, the fit will be snug and secure. You should know that different types of screening material may need different spline sizes. For example, tougher materials like PetScreen® and TuffScreen® are thinner, so you may need a smaller spline.
If you’re not sure which size to get, you can look at a spline diameter chart. These charts convert measurements between inches and millimeters, and they can also give you specific recommendations based on the type of screen you’re using.
What factors affect how long screens last?
Screen performance and longevity depend on a few key things:
- Environmental considerations: Sunlight, moisture, and extreme temperatures can shorten the lifespan of your screens. Think about using UV-resistant and corrosion-resistant materials.
- Intended use: What do you need the screen for? Insect protection? Pet resistance? Solar control? Choose materials and mesh sizes that are up to the job.
- Maintenance and care: Regular cleaning goes a long way. Use mild soap and water to get rid of dirt and debris.
- Frame material and construction: A sturdy, well-built frame is essential. Aluminum frames are a good choice because they’re durable and resist corrosion.
Don’t forget to measure your windows and doors carefully before you start shopping! A poorly-fitted screen won’t do you much good.
Tips and tricks for installation
If you’re doing the job yourself, here are a few things to keep in mind:
- You’ll want to have the right tools. A spline roller or screen mouse will help you install the spline, and a utility knife or scissors will help you trim away extra screening.
- Stretch the screening material as evenly as possible across the frame to get a nice, snug fit. You’ll also want to apply enough pressure when you roll the spline in.
- If your screen starts to sag, you can try re-splining it or tightening it up. And if the screen is damaged, you can patch it or replace it.
Frequently Asked Questions
How do I size a screener?
Sizing a screener depends on your specific needs. You’ll want to consider the material you’re screening, the desired throughput (how much material you need to process), and the available space. Start by determining the particle size you need to separate, then select a screen mesh size slightly smaller than that. For throughput, estimate the volume of material you’ll be processing per hour and choose a screener with sufficient surface area. Don’t forget to factor in the physical dimensions of the screener itself to ensure it fits your workspace.
What size are screenings?
“Screening size” is a bit ambiguous. Are you asking about the physical dimensions of a screening machine, or the size of the openings in the screen mesh? Screen mesh sizes are typically measured in microns or millimeters, referring to the diameter of the holes. Screening machines, on the other hand, can range from small, portable units to large, industrial-scale systems occupying significant floor space.
What are standard screen sizes?
There’s no single “standard” screen size, as it varies widely depending on the industry and application. However, common screen mesh sizes include those used for separating sand, gravel, or powders, and are often measured in mesh numbers (e.g., 20 mesh, 40 mesh), which correlate to the number of wires per inch. Machine sizes are even more diverse, ranging from small benchtop models to large, multi-deck industrial screeners.
What are the most popular screen sizes?
The popularity of screen sizes depends on the application. For example, in the food industry, finer mesh sizes are popular for sifting flour or removing impurities. In construction, larger mesh sizes are common for separating aggregates like sand and gravel. For home use, smaller, hand-held sieves with varying mesh sizes are often preferred for tasks like sifting flour or straining liquids. It really boils down to what you’re trying to achieve.
Wrapping Up
Choosing the right screen involves thinking about mesh size, material, and spline size. The right screen can make your home more comfortable, function better, and look more attractive.
When you’re making your choice, be sure to consider your own unique needs and the environment where the screen will be used.
