Casement Window Features and Options

A casement window is a single-sash window that cranks out, and both left-opening and right-opening windows are available. The screen is on the inside of the window. Casement windows are produced for new construction and for replacement windows in good, better and best grades.

There are two ways to buy casement windows:

Standard windows are built in a range of common sizes in ½” to 1” increments and sold online and by local and national home improvement stores. Regional brands and all major window brands including Pella, Andersen, Alside, Jeld-Wen, Simonton, Marvin and Milgard produce standard casement windows in one or two materials, and color and feature options are limited. The quality is usually in the good-to-better range.

Custom windows are not built until ordered by the customer in the exact sizes required. Materials available are vinyl, fiberglass, composite, wood and vinyl-clad wood. The range of options is much larger than for standard windows, and the quality of the various custom casement window lines is in the better-to-best range. Custom windows are produced in many series by all top local and national brands. Once the windows are ordered with the help of a sales agent or a website program, the windows take four to ten weeks to build and deliver.

Here is an overview of your casement window features and options for custom-ordered windows. Again, fewer options are available for standard or “off the shelf” windows.

  • Materials – Window frames are built with vinyl ($-$$$), wood composite ($$-$$$), fiberglass ($$-$$$) several species of wood ($$-$$$$) and wood with vinyl-clad or aluminum-clad exteriors ($$$-$$$$).
  • Colors and Finishes – Vinyl and fiberglass windows may be produced in several colors depending on the manufacturer. Composite, wood finishes and clad exteriors offer many more colors. Wood windows can also be ordered unfinished or primed and then stained or painted once installed. Note, though, that if you plan to have the windows stained or painted by a professional, it will cost much more than if the process is completed at the factory. You’ll only save money if you finish the windows yourself, and it will only look good if you have excellent skills.
  • Locks and other hardware – Finishes with variations of each include white, brown, silver, gold, bronze and brass.
  • Glass, Grilles and Screens – The glass package is often called the glazing, and your options include single, double and triple pane, insulated Low-E glass, packages designed for your climate – some Energy Star rated, tinted and textured glass, tempered and shatterproof glass. Grilles come in many styles including grille placement between glass panes for easier maintenance. Screens are produced in various styles and colors.

Then range for most standard and custom casement windows is:

  • Width: 13.5” to 36”
  • Height: 17.5” to 72”

Two windows in a single frame or two moving windows and a fixed center window in a single frame can double or triple the width.

The Advantages Of Casement Replacement Windows

Being as casement windows are one of the most popular types, listing the advantages for this type of window isn’t too hard at all. Casement windows:

  • Are Reasonably Priced
  • Are Energy Efficient
  • Are Available In A Variety Of Designs
  • Provide Good Ventilation

Reasonably Priced

Casement windows are one of the best priced replacement window types you’ll lay your hands on, with casement prices starting at just $150 with installation, you can buy them on the tightest of budgets. Casement windows are usually a similar price to double and single hung windows, obviously this price varies and will be dependant on many factors.

Energy Efficient

Casement windows are one of the most energy efficient windows, next to fully fixed frame windows. The sash of the casement window, when closed, forms a seal around the entire window frame, reducing the amount of air leakage (AL) which can pass between the inside and the outside space.

Available In A Variety Of Designs

The casement window type is available from most window manufactures including the biggest, such as Andersen, Pella and CertainTeed (MID). The casement windows offered by these companies, and others, come with a variety of finishes and a variety of colors, with a range of accessories such as chrome, vinyl or brass crank handles. You can also add a range of optional extras such as a surface grills and lead grills, this makes the casement windows more attractive to the eye and less “plain” looking.

Provide Good Ventilation

Casement windows usually allow two ventilation methods, one which allows you to open the window full and the other which allows you to open the window by a matter of centimetres whilst still retaining home security, preventing anyone from entering through the window. Either option is good for letting air into your home, particularly in the hotter summer months.

The Disadvantages Of Casement Replacement Windows

There are three main disadvantages to casement windows, mostly to do with their size and installation location.

  • Can’t Be Installed With Air Conditions
  • Can’t Be Installed In Conjunction With Storm Screens
  • Can’t Be Installed Above A Certain Size

Can’t Be Installed With Air Conditions

Most casement windows are designed to open outwards, this means that air conditioners cannot be installed within the top of the window, one of the big disadvantages with them.

If this is a big deal for you then you may want to consider alternative air conditioner installation methods (such as brick mounted) or look for a different type of window, such as the single hung sash which can accept most air conditioning units.

Can’t Be Installed In Conjunction With Storm Screens

Again, because casement windows open outwards, you can’t have storm screens installed on the outside of them since the screen would prevent the window from opening. As with the air conditioners mentioned above, if you need storm screens due to the area you live, double or single hung sash windows are probably a more viable option for you.

Can’t Be Installed Above A Certain Size

Casement windows hinge on one side and crank outwards to the left or to the right, for this reason they must be small enough to be able to support their own weight when left in the open position. Having a window which is too large would lead to structural failure in the window, for that reason casement windows can only be manufactured up to a certain size. This size is dependant on the manufacture, the window and the building it’s going into. Speak to a local window contractor for more advice.

Casement windows are very attractive, and they offer full-window ventilation. Because the windows crank shut, the seal is tight, energy-efficient and weatherproof. If the screen is removed, a minor hassle, the windows can be washed from inside. Some series of casement windows have semi-removable sashes that allow cleaning the outside from inside the house too. Otherwise, the windows can be opened and easily washed from outside.

For disadvantages, casement windows are more expensive than single-hung and double-hung windows of the same quality because the mechanics of a casement window must be excellent quality. In time, the cranks might need to be replaced. These windows are easier to break into too. Casement window size is limited because the entire weight of the sash must to be supported without bulking bracing.

Factors that Affect Casement Window Costs

The factors covered above – frame material, size, quality and whether the window is standard or custom – are the major determinants of cost. Replacement windows cost more to install than windows in new construction. Beyond these factors, there are two factors you can control.

Window manufacturers and installers have the best pricing in early spring and late fall where winters are very cold. In milder climates, windows can be installed in winter, and that’s a good time to find deals. On the other hand, when installers are busiest, window installation prices are highest.

Who you hire to install windows will affect cost. A handyman service is the cheapest route, but if the job is done poorly, it will end up costing money to repair or replace the windows or through higher energy costs if the windows don’t fit properly. On the other hand, if a general contractor arranges installation, you will be charged a premium for the GC’s services. The best method for saving on quality windows and installation is to request estimates from several licensed window companies that know they are competing for the work.
