The purpose of basement windows is to add appeal to your space by bringing in natural sunlight. When your windows are rusted, covered in debris, or doing little more than affording a view of an old, rusty window well, then they're not doing their job. So that's why we installed 4 of our EverLast Basement Windows. Our EverLast Windows are energy-efficient, vinyl-framed replacement windows. Having a covered window well keeps cold winter winds from blowing against the panes, while the Low-E double thermopane glass of EverLast Windows saves you on your energy bills. It's a small upgrade that really made a big difference in this homeowner home!
