You’re going to learn everything you need to know and probably more than you need to know.

There will be no reason you cannot make an educated decision on your windows after reading this article

We will provide you with all the information you need to know about a window and its parts. This way, when it comes time for replacement windows, you will be an informed customer and know exactly what to look for.

What are the Parts of a Window

A window is generally made up of three parts: the frame, the sashes, and the glass.

The frame is the outermost part of the window and is usually made of wood, metal, or vinyl.

The sashes are the inner parts of the window that hold the glass in place.

They are also usually made of wood, metal, or vinyl.

The glass is the clear part of the window that allows light to enter your home.

The type of frame, sash, and glass you choose will affect the look of your window, as well as the amount of light and air that can enter your home.

For example, windows with metal frames and glass panes tend to be more energy-efficient than those with wood frames and glass panes. However, metal frames can also conduct heat and cold, so they may not be the best choice for homes in climates with extreme temperatures.

When shopping for replacement windows, it is important to keep in mind the parts of a window and how they contribute to the overall look and function of the window. By understanding the parts of a window, you can make sure you choose a window that will complement the style of your home and provide the right amount of light and air circulation.

What are the Different Parts in a Window Frame?

Window frames are made up of several different parts, all of which work together to hold the window in place and keep it functioning properly.

Here’s a quick overview of the most important parts of a window frame:

  1. Head

The head is the horizontal piece at the top of the frame. It also helps support the weight of the window.

  1. Sill

The sill is the horizontal piece at the bottom of the window frame. It supports the weight of the window and helps to keep it level.

  1. Jamb

The jambs are the vertical pieces on either side of the window. They provide support and stability for the entire frame.

  1. Apron

Think of the apron on a window as the decorative piece that’s located below the sill. It’s like adding baseboards to the bottom of your walls. It’s there as a decorative piece that makes windows look more aesthetically pleasing.

  1. Wheep Holes

Wheep holes are tiny openings at the bottom of the exterior frame of your replacement windows. Although they are not in all windows, they are typically found on vinyl or metal window frames.

Window frames are essential parts of any window, so it’s important to know what each one does. With this knowledge, you can better understand how your windows work and keep them functioning properly for years to come.

Parts of a Window Sash

In short, a window sash is the moving part of a window that holds the glass in place. The term “sash” can also refer to the entire frame of the window. A window sash typically consists of two parts: the upper sash and the lower sash. The upper sash is usually fixed in place, while the lower sash is operable, meaning it can be opened and closed.

Window sashes are an important part of any window because they not only hold the glass in place, but they also help to seal in warmth or keep out drafts. In older homes, you may find windows with wood-framed sashes. Today, most windows have metal or vinyl-clad sashes.

  1. Window Pane

The window pane is the actual glass in your window. Most people refer to a window pane as the glass. Typically, if you are around on the job of a window replacement, the professionals at Window City Pros will be talking about window panes. So now you know a little “trade-talk”!

  1. Window Rail

A window rail is the top and bottom parts of the sashes. If you have a typical double-hung window, your window will have four window rails: two on the bottom sash and two on the top sash.

  1. Spacers

The spacers in windows are between the panes of a double or triple-pane window. Window City Pros uses a Super Spacer technology that allows for premium window insulation that will help the longevity of your window. This is one of the reasons why we have a lifetime warranty on our windows.

  1. Sash Lock (AKA: Cam Lock)

This is the safety mechanism on the inside of your windows that allows you to lock and unlock your windows. Once unlocked, you can open your window. If your sash is locked, it also acts as a stabilization and makes it so your windows are not rattling.

  1. Lift

The lift is just as it sounds. It’s the handle on your window that makes it easier to move your window up once your sash is unlocked.

  1. Weatherstripping

Weatherstripping is used to provide more barrier to outdoor elements. The better your weatherstripping the more efficient your windows are. When you open and close a solid window, you will sometimes hear a suctioning noise. That is the weatherstripping. Window City Pros uses the premium weatherstripping seal on the market. It is the same style as what your refrigerator uses. We all know that refrigerators need to have a great seal or your energy bills will be high. It’s no different for windows. This is why customers trust the pros at Window City Pros.

Storm Sash

A storm sash is a separate sash outside of your normal sash that is typically used on single hung windows. Some storm sashes can be used to open the window, but most are not. These are typically sashes that can be removed depending on the season. Although some people leave them in year round. Storm sashes are not very common due to the modern window replacement technology.

Other Window Components

Casing

The molding that goes around the window frames on the exterior of the window is referred to as the casing. This casing is put around the exterior of a window in order to prevent external elements from coming inside the home.

Fixed Panel

Fixed panels is an inoperable piece that is most commonly seen in single hung windows. It is the set-in-place window pane.

Grilles

The decorative piece of acrylic or plastic that gives a window the appearance of multiple windows is the window grille.

Mullion

Whenever there is a need for two or more windows to come together, a piece called a mullion is used.

Window Screens

A window screen is the woven mesh material on the exterior of your window. Screens are an important asset as they keep out leaves, insects (we wish they would keep them all out!), and other airborne debris.

Energy-Efficient Windows Definitions

Most new or replacement windows have an entire window system that is not noticeable to the untrained eye.

One of these parts that are nearly impossible to know without someone teaching you is the energy efficiency aspects of windows.

Most of the following windows contain energy-efficient components that we will list below:

  • Double hung windows
  • casement windows
  • single hung window
  • picture window
  • and more

Argon Gas

Argon gas is a common choice for windows because it is an inexpensive, non-toxic, and inert gas. Argon is used in double-glazed windows to help prevent heat loss. The argon gas between the two panes of glass creates a barrier that slows down the movement of heat.

Argon gas is also used in triple-glazed windows. In this type of window, three panes of glass are used with two layers of argon gas in between the panes. Triple-glazed windows are more energy efficient than double-glazed windows because they provide an additional layer of protection against heat loss.

Argon gas is odorless, colorless, and non-flammable. It is also non-reactive, which means it will not corrode metal or react with other chemicals. Argon gas is safe to use in windows and poses no health risks.

The benefits of argon gas in windows include:

1. Increased energy efficiency – Argon gas helps to prevent heat loss, making windows more energy efficient.

2. Cost-effective – Argon gas is an inexpensive option for increasing the energy efficiency of windows.

3. Non-toxic and safe – Argon gas is a safe and nontoxic option for use in windows.

4. Inert and non-reactive – Argon gas is inert and will not react with other chemicals or corrode metal.

Argon gas is a safe and effective way to increase the energy efficiency of windows. It is also an inexpensive option that can help to save on energy costs. argon gas is non-toxic, making it a safe choice for use in homes and businesses.

Low-E Glass

Low-E in windows is a type of window glass that has been treated with a low-emissivity coating.

This coating helps to reflect heat back into the room, making it more energy efficient.

Low-E glass is an important factor in choosing energy-efficient windows!

If you are looking for top of the line window that will regulate the temperature in your home all year round, find the best Low-E glass windows.

Whether you choose our Pro-Tech windows or competitors, always compare the Low-E rating!

What is a Triple Pane Window

A triple pane window is an energy-efficient window option that can help to reduce your energy bills.

Triple pane windows are made with three layers of glass, which helps to create a barrier against heat loss and gain.

This type of window is also typically more airtight than other window options, further reducing the amount of energy that is lost through your windows.

If you are looking for an energy-efficient window option, triple-pane windows are a great choice. Not only will they help you save money on your energy bills, but they will also help to keep your home more comfortable throughout the year.

Types of Window Materials

There are a few different types of materials that windows can be made out of. These include wood, vinyl, and fiberglass. Each type of material has its own benefits and drawbacks that should be considered before making a purchase.

Wooden windows are classic and elegant but require more maintenance than other types of windows. They must be regularly sealed and painted to protect them from the elements.

Vinyl windows are low-maintenance and energy-efficient, but may not have the same aesthetic appeal as wood or fiberglass.

Fiberglass windows are durable and can resist high winds and heavy rains, but they may be more expensive than other types of windows.

When choosing new windows for your home, it is important to weigh the pros and cons of each type of material to find the best option for your needs.

What is the Best Window Frame Material?

There are a few different types of window frame materials on the market today. The most popular ones are wood, vinyl, and aluminum. Each one has its own set of pros and cons that you should consider before making your final decision.

Wood frames are the most traditional option. They’re also generally the most expensive. Wood is strong and durable, but it can be susceptible to rot and insect damage if it’s not properly maintained.

Vinyl frames are a more affordable option that still offers good durability. They’re also easy to care for since they don’t require painting or staining. However, vinyl can warp or crack in extreme temperatures.

Aluminum frames are lightweight and low-maintenance, but they’re not as durable as wood or vinyl. They also conduct heat and cold, which can make your home uncomfortable.

So, what’s the best window frame material?

It really depends on your needs and budget.

Wood frames are the most traditional option, but they’re also the most expensive. Vinyl frames are more affordable and easy to care for, but they can warp or crack in extreme temperatures.

Aluminum frames are lightweight and low-maintenance, but they don’t offer the same level of durability as wood or vinyl. Ultimately, the best window frame material for you will be the one that fits your needs and budget the best.

Window Balances

Window balances are an extremely component on windows.

Window balances are used to counter-balance sashes, which makes the sashes easier to operate (opening and shutting). This is the component that prevents your windows from slamming shut.

Modern replacement and new construction windows use block and tackle balances and the tension is supplied by springs instead of weights.

You may see in older and more outdated windows a weighted pully system that was used to be the window balance.
