Pella Corporation was founded in 1925 as the Rolscreen Company. Initially, their company was most widely known for its “disappearing” Rolscreen window screen. Updated in its design and still popular today, the patented Rolscreen rolls out of sight when you don't need it. Pella patio doors and storm doors also offer their Rolscreen technology. In 1992, their company changed its name to Pella Corporation, to better reflect their entire product offering. Today, the Pella family of brands offers a full range of quality residential and commercial products for new construction, remodeling and replacement projects. They are particularly proud that they can offer their customers windows and doors to meet virtually any style or budget.
