How to Buy Window Film: 3 Ways

Wondering how to buy window film on Concord Window Film? Well, we’ve got 3 ways you can purchase ComforTech Ceramic Series window film. Are you someone who wants to make installation as easy and pain-free as possible? Or you are a home improvement warrior? No matter what kind of DIYer you are, we’ve got you covered! Here’s how to buy window film on

How to Buy Window Film

We’ve got three ways you can purchase ComforTech Ceramic Series window film: in rolls, in pre-cut kits that fit most standard size windows, or in custom kits that we cut to your window size. Each option has its merits and depends upon two factors: (1) the number and size of windows you have and (2) the time and effort you want to put into the project.

What to Do First

There are a couple of things to do before you decide which option to purchase: choose your shade of film and measure your windows:

Choose Your Shade

ComforTech Ceramic Series comes in five performance shades that are from darkest to lightest: 05, 15, 25, 35, 45.  All of our film provides solar control, glare reduction, fade protection, energy efficiency and UV protection. The amount of each benefit increases with the darkness of the film:

And, if you are interested in daytime privacy, only ComforTech 05, 15, and 25 will provide that. 

Use our guide to select the shade of window film you want to purchase. If you are unsure, consider ordering a window film sample kit to view the film in your home.

Measure Your Windows

Then measure the width and height of the glass portion of your windows only. Do not include the window frame. Add one inch to the width and the height for exact trimming to size at the window (some older windows may not be plumb and final trimming at the window is essential to ensure a perfect installation).

How to Buy Window Film Option #1: Rolls

We sell rolls of film in three widths: 36″, 60″ and 72″ and three lengths: 25′, 50′ and 100′ (except for 72″ rolls that only come in 50′ and 100′). This is the least expensive way to purchase our film – rolls of film run around $2.35/square foot.  If you’ve got a big job to do and are comfortable with cutting film, this option might be for you.

Rolls Sizes Available

We have several roll sizes available:

How to Buy Window Film Option #2: Pre-Cut Kits

We also sell film in pre-cut kits that we keep in inventory for fast shipping. This is a great choice if you have standard shape and size windows. Pre-cut kits run around $3.20/square foot – but there is minimal waste material!

Pre-cut Kit Sizes Available

We have four pre-cut kit types we keep in stock that fit most standard windows and doors of that type. Please note that you can orient the film either way, so in other words, you could use a double-hung kit for a window that is 30″ x 36″ as well.

Double-hung Window Kit

A double-hung window is one where there are two sashes stacked on top of one another, and both sashes move. A single-hung window is the same configuration, except only the bottom sash moves; the top sash is stationary.

Each double-hung window film kit comes with two pieces of 36″ x 30″ film. The double-hung window kit also works for single-hung windows.

Casement Window Kit

According to Andersen Windows, “casement windows are hinged on the side and crank open outward to the left or right allowing for full top to bottom ventilation.” Casement windows are often used over kitchen sinks or other countertops because it’s thought its harder to open a double-hung or different window type if you have to lean across the countertop to reach it.

Each casement window film kit comes with two pieces of 20″ x 60″ film. This kit type can also fit sliding windows which are also two vertical sashes placed side-by-side.

Storm Door Kit

A storm door is a door that is installed on the outside of an exterior door. Storm doors were invented in 1861 to protect more expensive wood entry doors from the elements. This holds true today, but folks often like to have storm doors installed to let light into the home and ventilation (when the storm door glass is replaced with a screen).

Each storm door kit comes with one piece of 36″ x 76″ window film.

Patio Door Kit

A patio door is a glass door that has two sides or panels of glass: one that opens and one that is stationary. Patio doors go by many names: sliding glass doors, sliders, patio sliders, french doors, etc. Really there are two main types: sliding and regular hinged.

The hinged doors are typically referred to as French doors and have one stationary pane of glass and one pane that opens like a door.

Sliding patio doors are similar, except they don’t swing open like French doors, they slide on a track. Sliding patio doors are a great alternative to traditional hinged doors because they don’t require as much space to operate.

Each patio door kit comes with two pieces of 36″ x 76″ window film.

How to Buy Window Film Option #3: Custom Cut Kits 

Custom kits can be ordered for our ComforTech Ceramic Series window film only. Kits are available in six standard widths: 24”, 30”, 36”, 48”, 60”, and 72” and in lengths starting at a minimum of 12″ and increasing in 1′ increments up to a maximum of 180″.  Please note, that ComforTech film is not approved for windows over 40 square feet in area due to the increased risk of thermal stress failure with the glass. Custom kits cost $4.00/square foot.

How to Buy Window Film in Custom Kits:

Once you have your window dimensions and have rounded up to the next nearest inch for trimming, visit our custom kit page to build your window film kits:

You can also access the Custom Kits page at this link:

Once there, you will first choose your shade:

Next you will choose your width. Custom kits have standard width options of: 24”, 30”, 36”, 48”, 60”, and 72”. So for the width, round up to the next largest standard width available. So for example, if your window measures 28″ wide, adding 1″ for trimming to the exact size yields 29″. Round up to the next available width which is 30″ and select that. 

But remember, you can orient the film either way, so if you have a window that is 13″ wide by 29″ high, you can choose a width of 30″ and then choose 13″ for your height.

Finally, you will choose your length. Lengths are available in 1″ increments up to 180″ and can be entered as calculated (measured with the addition of 1″ for exact trimming).

A pro tip on lengths and widths: since the film can be oriented either way, enter the film both ways if you can, to see if one option is less than the other. Film comes to us in standard roll width sizes, so the closer you can get to one of the standard widths for one of your dimensions, the less you will pay for each piece of film.

Benefits of Custom Kits

  • Saves you time because the film is pre-cut for your specific windows
  • Prevents having to handle a bulky and heavy roll of film
  • No film waste

Other Things to Note about Custom Kits

  • There is a $15 custom kit handling fee for all custom orders.  Product returns are not allowed for this item as the film is custom cut to size.
  • The lead time for custom kits may range between 7 to 10 days as all orders are fulfilled from our East Coast Service Center
