Different Parts of Replacement Windows

Windows may not seem like much at first glance, but some windows styles can be fairly complex with a lot of components. They are so much more than just pieces of glass stuck inside a frame. And while most windows have similar parts, the location and functionally of those parts will vary from style to style. If you are shopping for replacement windows in Carlsbad, CA, it is a good idea to know and understand at least some of the basic window parts to help mitigate confusion. These are a few of the components to know:


The frame surrounds the window and secures it to the opening in the wall. The top portion of the window frame is called the head. The sides of the framework are called the jambs. And the bottom of the window frame is called the sill. The framework gives replacement windows the support and structure to remain in place even after years of use and exposure to the elements. Window frames come in a variety of materials including vinyl, fiberglass, wood, and aluminum. The type of material you choose will largely depend on the performance and longevity you expect to get from your windows. Vinyl is the most affordable material and fiberglass is usually the most expensive.


One of the main reasons why homeowners get replacement windows is to boost energy savings. This is even more important now that people are spending so much time at home. And insulation technology has come a long way. Modern window frames are often made up of interlocking chambers. This helps make replacement windows stronger and durable, while also remaining lightweight for transport and installation. But it doesn’t always remain empty space. Installers fill the frame with spray insulation made with polyurethane foam. This helps cut down on heat coming directly through the frame.


The sash is the part of the window that holds the glass, and it usually sees the most action. A sash can be fixed or operable, depending on the type of window. Picture windows have one fixed sash, which means it does not open and close. Sliding windows have one stationary sash and one operable. The moving one slides back and forth on a track to open. Casement, awning, and hopper windows all have one sash on hinges. These sashes usually open out, but some hopper windows pull in to open. Single-hung windows have one fixed sash and one operable sash. This moving sash slides up and down with a spring-loaded balance system. And double-hung windows have two sashes that move up and down.

Glazing systems have come a long way over the last few years. They are so much more than just pieces of glass. Insulated glazing units (IGUs) installed in a window sash feature multiple panes of glass. They are set apart with spacers and then sealed together as one unit. Homeowners can get windows with two panes, three panes, or even four panes of glass for added security and insulation. Between the panes is a special inert gas that helps cut down on heat transfer. Manufacturers can also apply special coatings to the glass to reflect light and heat to make the home even more efficient.

Yes, there are a lot more to replacement windows in Carlsbad, CA than you might think. And knowing some of these basic components will make finding the right products a lot less confusing.
