Types 
 |
Casement Windows - Contemporary style with more light and a larger view. Casement windows are more common in newer homes and are typical in the western part of the United States. Pella® casement windows are a great choice where windows can be difficult to reach, such as over the kitchen sink. Our patented Unison Lock system secures both upper and lower locks with a single easy-to-reach handle. |
 |
Awning Windows - Similar in design to casement windows, but wider than they are tall. Awning windows are commonly used for ventilation when placed above or below a window or door; they provide more light and are often used in homes with traditional, double-hung windows. |
 |
Double-Hung - A more traditional appearance than casement windows. Double-hung windows are common in older homes in the eastern part of the United States. They're a great choice if you want to maximize the amount of wood on the interior of a home. Double-hung windows come in larger widths (up to 45") and may help save money-put one larger window in place of two smaller, narrower casement windows. |
 |
Bay/Bow Windows - Window combinations that reach out into the world and capture the view in a limited amount of space. Bay windows are typically three windows joined together. The center window is often fixed with operating double-hung or casement windows on the sides. Bow windows consist of four or more casement windows joined together to form a graceful curve. You can choose fixed windows (that cannot be opened), vented windows (that can be opened) or a combination of the two. |
 |
Fixed Windows - Windows that cannot be opened. Available in a wide range of sizes, in rectangular and custom shapes, and in a variety of standard, feature and custom exterior cladding colors. They can be used by themselves, in a variety of applications or with other products, providing endless possibilities. Fixed frame windows are available in sizes up to 48 square feet. |
 |
Circlehead Windows - A little touch that makes a big difference. Circlehead windows are designed to fit perfectly over other windows and doors. They can also be beautiful accents on their own. |
Types 
 |
French Hinged Patio Doors - A classic look. Often used as an entryway from a patio or deck. Out-swing hinged doors are a good option if interior wall space is limited-and they also perform better in high-wind environments because the wind simply presses the operable panel(s) tightly against the jamb. The harder the wind blows, the tighter the seal. |
 |
Sliding Patio Doors - Require much less space than a hinged door. Sliding doors are available in French style with wide wood door panels for a traditional look, or in a contemporary style with narrow door panels and more visible glass area for a clean, contemporary look. |
 |
Pella Rolscreen® Collection - Retractable screen provides ventilation when you need it and a clear view when you don't. Exclusive operating system lets you adjust the screen to any position allowing you to raise and lower the screen with one hand. |
 |
Fiberglass or Premium Steel Entry Systems. |
 |
Interchangeable Storm Doors - Feature a full glass panel that can be switched out for a full screen-excellent for seasonal ventilation changes. Also called a "fullview" style, these doors provide maximum light and showcase your entry door. |
 |
Self-Storing Storm Doors - Screen and glass both stay in the door year round. Glass panel is raised for airflow for instant ventilation changes. Pella® self-storing storm doors are available in fullview styles for maximum views, midview styles with more frame area for added durability and highview styles that offer the most privacy and are great for high-traffic entryways. |
Skylights 
VELUX® skylights are designed for overhead, out-of-reach applications or for in-reach applications that do not require egress emergency escape capabilities. They come in a wide range of sizes and features with a full assortment of blinds available.
 |
Electric venting skylights Skylights that open at the touch of a button. |
 |
Manual venting skylights |
 |
Fixed skylights with flap Skylights that provide an outside view with limited ventilation. |
