Buying Guide: Key Purchase Considerations And Comparisons
When selecting window well covers or grates, consider the following factors to optimize safety, daylight, and durability.
- Material: Metal grates using tempered aluminum offer high strength with light weight, while polycarbonate covers provide clear visibility and UV resistance. Choose based on exposure and load expectations.
- Size and fit: Accurately measure window well depth (D) and width (W). Many Adjust-A-Grate models specify exact fit ranges; ensure the chosen grate matches the well’s radius and dimensions for a secure fit.
- Light transmission: If daylight into basements is a priority, select grates or covers that allow up to 90% natural light through perforations or clear polycarbonate.
- Durability and weather resistance: For exterior installation, polycarbonate with UV coating resists yellowing and cracking, while metal grates resist impact and corrosion with proper coating.
- Safety features: Look for designs that prevent accidental dislodging, include proper anchoring hardware, and, where required by code, provide a safe egress alternative (like a ladder when applicable).
- Installation and maintenance: Consider whether hardware is included and whether installation requires professional tools. Maintenance should be simple—cleaning polycarbonate with mild soap and water is commonly sufficient.
- Code compliance: Some jurisdictions require specific egress or safety standards for window wells. Ensure selected products meet local regulations for emergency egress and safety.
- Aesthetic considerations: Clear polycarbonate keeps exterior appearance minimal and unobtrusive, while metal grates can offer a robust industrial look. Choose based on home style and curb appeal.
These options present a spectrum of appearances and performance characteristics, from rugged metal grates designed for larger wells to transparent or UV-stable polycarbonate covers that maximize natural light while protecting the opening.
