DIY Crittall Windows: How to Create Beautiful Industrial Steel Frames for Your Home

Crittall windows are iconic, combining the timeless charm of industrial design with the practical benefits of steel-framed glass. Known for their sleek metal frame and minimalist aesthetic, these windows can completely transform the ambiance of a room, adding brightness, style, and an air of modernity. While original Crittall windows can be expensive and difficult to source, DIYing your own version is a great way to achieve the look at a more affordable price. This detailed guide walks you through the process of creating your very own Crittall-style windows, from materials to installation.

What Are Crittall Windows?

Crittall windows, originally designed in the UK in the early 1900s, are renowned for their slim, steel frames. They were primarily used in commercial and industrial buildings due to their strength and ability to maximize natural light. Over the years, these windows have become a signature feature in contemporary homes, lofts, and even gardens, offering an industrial yet refined aesthetic. The Crittall design is characterized by its use of thin metal frames that divide the glass into smaller panes, creating an intricate grid effect.

While traditional Crittall windows can be expensive, DIY enthusiasts have found ways to replicate the look using more affordable materials. If you’re looking for a bold way to update your living space, building your own Crittall-style windows is a fantastic way to introduce light and a modern design element to any room.

Why Choose DIY Crittall Windows?

1. Cost Savings:

Opting for DIY construction can be significantly cheaper than purchasing pre-made Crittall-style windows. By sourcing your materials and assembling the windows yourself, you can save money while still achieving a high-end look.

2. Full Customization:

One of the best things about DIY projects is that they give you complete control over the design. You can tailor the size, finish, and overall look of the windows to suit your specific needs and preferences.

3. A Unique, Industrial Look:

Crittall-style windows are perfect for homeowners seeking an industrial or modern aesthetic. The mix of steel and glass not only maximizes natural light but also creates a visually striking focal point in any space.

Materials and Tools You’ll Need:

Before diving into your DIY project, gather the following materials and tools to ensure a smooth process.

Materials:

- Steel or Aluminum Framing: Steel is the traditional material for Crittall windows, but aluminum is a lighter, easier-to-handle alternative.

- Glass Panes: You’ll need tempered glass panes, ensuring they are cut to fit your custom frame dimensions.

- Rubber Sealant: To prevent drafts, moisture, and air leaks, use high-quality rubber seals around the glass.

- Paint or Powder Coating: Steel can rust over time, so it’s crucial to protect it with paint or a powder coating finish.

Tools:

- Measuring Tape: Accuracy is vital in making sure all parts fit together perfectly.

- Saw or Metal Cutter: To cut the steel or aluminum framing to the correct size.

- (for Steel Frames): If using steel, welding may be required to join the frame sections.

- Drill and Screws: For securing the glass panes and frame together.

- Level: Ensures your window frame is perfectly square and aligned.

- Safety Gear: Wear gloves, goggles, and ear protection when working with power tools and metal.

Step-by-Step Guide to Building DIY Crittall Windows

Step 1: Measure Your Window Frame

Careful measurement is key to ensuring that your DIY window fits perfectly into its intended space. Measure both the width and height of the window opening, and add a little extra space around the frame for the seals and clearance.

Step 2: Cut the Steel or Aluminum Frame

Using a saw or metal cutter, cut your steel or aluminum pieces to the desired lengths. It’s essential to cut with precision to avoid uneven frame edges. If using steel, a welder may be necessary to join the pieces together securely.

Step 3: Assemble the Frame

Start assembling the frame by welding (for steel) or connecting the aluminum pieces using joiners or brackets. Be sure to check for squareness at all angles to ensure the window will sit properly in the opening.

Step 4: Install the Glass

Once your frame is assembled, insert the glass panes. Make sure to use rubber seals around the edges to keep the glass securely in place and to prevent air leaks. The sealant will also help to hold the glass firmly inside the frame.

Step 5: Finish and Paint

To protect your steel frame from rust, finish it with a protective paint or powder coating. Choose a matte black or metallic finish for an industrial look, or opt for any color that complements your decor. Let the frame dry thoroughly before proceeding.

Step 6: Install the Window

With the frame and glass completed, it’s time to install the window in your prepared opening. Use a level to ensure it’s perfectly aligned, then secure it in place using screws and anchors. Check for proper fit and make adjustments as needed.

Challenges to Keep in Mind

While DIY Crittall-style windows are a fantastic project, there are a few challenges to be aware of:

- Precision Matters: Since you're working with metal and glass, even small mistakes in cutting or measuring can result in misalignment, leading to a poor fit.

- Heavy Frames: Steel can be heavy, so make sure you have help when lifting and installing the frame.

- Welding Skills Required: If you're using steel, welding is likely necessary, which requires some experience or professional help.
