Sizes and fit 64 sizes available so you can find the right fit for most windows. For easier installation and a precise finish, a slightly larger size and trim the excess to fit. Material and performance Made from fibreglass mesh for improved visibility compared with standard polyester screen mesh. Fine mesh allows fresh air and daylight through while blocking insects and outdoor debris. Upgraded adhesive and stronger magnets hold the screen securely in place for longerlasting use. Compatibility Designed for a wide range of window types: singlehung, doublehung, casement, bay or bow, awning, sliding sash, storm windows, and more. Can be used to add a screen where none exists. Easy installation and maintenance Magnetic attachment makes installation fast and tool; trim excess material for a custom fit. Stable magnetic hold reduces sagging and accidental detachment; remove and reinstall as needed for cleaning. Practical use scenarios Kitchen window: open for ventilation while keeping flies and cooking odors under control. Nursery or bedroom: let fresh air in without exposing sleeping children to insects. Older or rental windows: add a removable screen to windows that lack factoryinstalled screens. Why choose this screen Broad size range and trimtofit option for a custom installation. Durable fibreglass mesh with improved visibility and a fine weave to keep out pests. Stronger adhesive and magnets for a more stable, longerlasting attachment.
