Pella Impervia Double Hung Window

Pella Impervia double hung windows are designed and engineered so that the bottom window slides up, partially covering the top sash when opened, allowing for outstanding ventilation. A double hung window has two stacked windows that are each able to move up and down independent of one another. Pella’s double hung windows are a wonderful option for any home – classic or modern – and can be customized to meet any design needs. Pella Impervia windows are made with a low-maintenance fiberglass material that is able to withstand the harshest of elements – from coast to coast.
