If you have already started thinking about a window replacement project, you’ll probably realize that the same window style won’t work across the whole house. Different windows are best suited for different rooms depending on what the room is used for, where it is located in the house, and even which side relative to the Sun the window will be on. Don’t worry we’ll explain. But this means you will have to make a choice: to replace the existing window with the same style or get something completely different installed in that opening. Most homeowners, in fact, are happy to get windows that function and look the same as their existing ones but in a more energy-efficient build and design. But getting different windows with different rooms in mind, can help balance the comfort across your entire home, and even save money in areas where maximum efficiency is not required.

Today we’ll focus on master bedrooms. Like the crown jewel of the house, the master bedroom is a room that requires the best energy efficiency, most comfort, and often additional privacy. If there is one place you should consider getting the highest quality windows, it is in the master bedroom where you sleep. The window openings in master bedrooms can range in size, which makes several window styles ideal for use in this room.

Why vinyl windows are better

Before you start thinking about which window style to get, you’ll have to decide to on which material the window is manufactured from. Thankfully there aren’t too many choices when it comes to materials, and each window material has its distinct pros and cons.

Traditionally windows used to be manufactured from aluminum, wood, or a combination of the two materials. Later developments resulted in combination windows manufactured from wood and vinyl. Today, most windows for the replacement market are manufactured almost entirely from vinyl. Vinyl is the material of choice because it offers great energy efficiency at a relatively low manufacturing cost. It also isn’t as prone to deterioration as wood or aluminum windows.

Wood windows still exist today, but they are more difficult to manufacture and make efficient, driving the cost up when compared to vinyl. Another emerging technology are fiberglass windows. Fiberglass windows are the most efficient option on the market today but are much more expensive to manufacture, and therefore cost a lot more than vinyl. That’s why fiberglass windows are mostly reserved for high-end replacements.

Vinyl is the best material of choice for replacement windows because it offers great performance and durability for a lower compared price than windows manufactured out of wood or fiberglass.

Best window styles for master bedrooms

As we mentioned above, you should have the most efficient windows in your home in your master bedroom and other bedrooms. When it comes to energy-efficiency and comfort, crank windows are the best option for keeping the heat inside on a cold day. Casement and awning windows utilize compression seal technology around the frame of the window. When the sash is cranked into a closed position, the compression seal evenly fills the space between frame and sash, making the window airtight. For this reason, casement or awning windows are ideal for use in any room.

Because they are designed to be longer in height than in width, casement windows can’t always be manufactured to match big openings. Windows in the master bedroom are usually bigger than a single casement window. For this purpose, it is possible to manufacture casement windows in combination with other casement or fixed windows.


Casement-Fix Combination

As you can see in the video above, one of the most popular combinations for casement windows is the “casement-fix” combination (also pictured below). This combination puts together a casement window and a fixed inoperable one. The inoperable window adds extra efficiency and the operable casement part allows for ventilation whenever you want some fresh air in your bedroom.

A fix-casement combination features an operable and a static window.

One thing to consider when picking the window combination and arrangement is what kind of window covers you envision on your new windows. Drapes and blinds are the two most popular choices. But as you can see below, the casement-fix combination doesn’t ideally suit windows with drapes, as the joint now runs right down the middle and obstructs some of the view and natural light entering your room.


If you are considering getting drapes or curtains for your new windows, combinations where the casement takes one or the other side of the window are better. The window can still be accessed with ease, while the middle is unobstructed.

Fix-Casement-Fix Casement and Casement-Fix-Casement combinations

Another great option for bigger openings is a combination of three windows including one or two casements. In these combinations, the casement window goes in the middle or on the sides respectively. The pictures below demonstrate the two different combinations.

A fix-casement-fix combination has two fixed windows with an operable casement window in the middle.

The combination with the casement window in the middle (shown above) is ideal for windows with drapes or curtains. You can still open the curtains to the sides and have the window open without the wind blowing fabric all over the place.

The combination below is called a casement-fix-casement and features casement windows on each side of the fixed unit. This type of combination is ideal if you are considering getting horizontal blinds for your windows. The blinds can be lifted to operate the window, and the unit still provides great views without the covers getting in the way.

A casement-fix-casement combination offers a smaller operable casement on each side of the fixed unit.

Best upgrades for your bedroom windows

Although you should consider getting the most efficient windows for your master bedroom, it is still good to get some additional upgrades. Some of these upgrades further improve the energy efficiency of your home, but they are all designed to make your room more comfortable.

Low-E Coatings

Depending on where you buy your windows from, there is a good chance they already come with one or two Low Emissivity coatings. Low Emissivity coatings are a great add-on to windows because they serve several purposes. Low-E keeps your home warmer in the winter by retaining more heat inside and preventing it from escaping. In the summer, the coating keeps the cool air in and reflects bad UV radiation from damaging your home and furniture.

Depending on which side of the house your windows are located and how much direct sunlight they receive, you may benefit from getting additional Low-E coatings. Windows on South and West facing walls generally receive more direct Sun exposure and UV. It is good to consider extra coatings in these rooms.

SSP Glass

SSP Glass, known as soundproof and security glass, is another great upgrade you may consider in your master bedrooms. While security is not always a priority for master bedrooms because these windows are often on the second floor, having soundproof windows in a room where you sleep can improve your comfort and well-being even more.

The inner pane of SSP glass is actually made of two panes of special glass put together for improved security.

SSP Glass essentially has three panes, but two of the interior panes are bound together with a PVB interlayer in between. This fused pane is nearly impossible to break and stays intact even after it is smashed. It also significantly reduces sound transmission and improves the window’s STC (Sound Transmission Class) performance.



Because master bedroom windows are often located on the second floor or in a hard to reach the place at the side of the house, cleaning and maintaining them can be a hassle. If that’s the case with your property you may want to consider getting windows with a SimplyClean coating.

SImplyClean is a coating that is applied on the exterior side of the glass. As dust and debris gather on the surface of the coating, it is depleted and dissolved under the direct sunlight. When it rains, the broken down particles are washed away. Having a SimplyClean coating on the windows also means they will not have streaks after they are washed or rained on.

SimplyClean (right window) leaves your glass streak-free after it rains.
