Window and door screens have evolved in remarkable ways over the years. From aluminum mesh to fiberglass. From large, hard-to-see-through yarns to micro-diameter threads that provide a clearer, better view.

Modern technology has given us screens that are made of much better materials than “old-school” aluminum mesh. Today we have durable, fire-retardant fiberglass yarns that are coated with a protective vinyl to make them hold up better for many years. Unlike aluminum, fiberglass mesh won’t rust, corrode or stain.

Mesh size is another important factor in window and door screens. Yarns that are smaller in diameter actually provide a better view of the outdoors and even allow more airflow through the screen. And the tighter the mesh, the more effective these screens are at keeping out insects—even the tiniest gnats.

The newest technology now allows screens to provide antimicrobial protection as well. This means that screens can protect against the growth of stain-causing bacteria and mold and mildew that can degrade the fabric. This, in turn helps make homes safer and healthier for families—because those bacteria and mold can cause illness or allergies. Screens that incorporate antimicrobial technology also stay cleaner for longer in between cleanings—an important benefit for busy homeowners and working parents who have less time to devote to cleaning!

One last thing to consider in regard to window and door screens is how “Green” they are—how good are they for the environment? Some screen manufacturers have had their new products tested to see if they meet strict chemical emissions limits, which contribute to the creation of healthier homes. BetterVue screens—offered on Gorell products—have achieved the prestigious GREENGUARD Indoor Air Quality Certification.

Even though it might seem screens are not as important today because we keep our homes closed up most of the year, it’s still important to ask about the screens that come with the windows or doors you’re planning to purchase because there will be times you want your windows and doors to be open. Screens provide beauty, protection against insects and bugs, and mold protection, as well as provide a breath of fresh air and a vie

This past winter produced record snowfalls and cold temperatures for many parts of the U.S. The gradual thawing of built-up snow and ice may have exposed your home’s exterior, particularly your windows and doors, to damp conditions for a prolonged period of time. You may have also experienced cold drafts from some of your windows. This can be a sign of worn weather-stripping or deteriorated exterior caulking. Spring is a great time to inspect your existing windows and doors to ensure proper operation and resistance to air and moisture infiltration. Below is a quick checklist of things to look for:

1. Inspect the caulking around the exterior of your windows/doors for cracks, breaks or separation. If sections are damaged or missing, it’s advisable to replace all  the  caulking in that area.  Remove the old caulking, clean the surface area and apply  a new bead of silicone caulking to create a good seal between the your windows (or doors) and your home’s exterior.
2. If you have wood windows or patio doors, make sure the exterior wood is free of rot and is protected with paint or stain meant for exterior usage. Paint that’s chipping or peeling should be cleaned off and the surface repainted to prevent moisture penetration.
3. Ensure your windows and doors are free of mold and mildew, which can be caused by prolonged exposure to damp conditions. Use cleaning products that won’t stain, scar or damage the materials used in the construction of your existing windows and doors.
4. Clean the sills of windows and patio doors to remove built-up dirt and debris. This is particularly important for sliding patio doors to ensure problem-free operation.
5. Check that window screens fit properly and are free of holes or tears. If you have a damaged screen, your local hardware store can help with replacing the existing screen with new screen material.
6. Check that existing weather-stripping is plush and undamaged to minimize air infiltration. Replacement weather-stripping can be purchased at most hardware stores and is easy to install.
7. If you have double-hung windows, make sure you can easily lift the sash and that it remains in place once opened. If the sash starts to drift back down or requires significant force to lift, a problem with the existing balance system may need to be addressed.
8. Check that window/door hardware—like handles, cranks and locks—are operating properly and are not loose. If necessary, the manufacturer of your windows/doors should be able to provide replacement parts or instruct you on where to get them.
