Why Do Large Windows Need Special Window Treatments?
Large windows are designed to let as much light in and highlight views, but without the right window coverings, they often create glare, privacy issues, operational challenges, and fading of interiors. Because of their scale, they require heavier, more durable mechanisms than standard windows to ensure smooth daily operation. The wrong product will feel heavy, operate unevenly, or block more of the view than expected.
