6 Best Storm Window Companies

Storm windows provide extra protection to homes located in inclement climates. Their extra glass pane adds durability and helps cut down on heating and cooling costs, providing energy savings.

Most storm windows go over existing windows and are easy to install yourself, though there are some permanent options. This guide breaks down all the information homeowners need to know, such as storm window brands and pricing, plus recommendations for the best window replacement companies.

Storm windows are simpler and more affordable than standard replacement windows. Below are the main factors to consider when choosing storm windows for your home.

Types of Storm Windows

Manufacturers create storm windows in three main styles:

• Exterior storm windows: Exterior storm windows help improve existing windows’ performance and energy efficiency. They come in vinyl, aluminum, and wooden frames. A two-track storm window fits in a double-hung window and uses a fixed half-pane of glass and a fixed screen on the same track. Triple-track configurations add greater ease of motion and ventilation. A two-track storm window is used for sliding windows, which open horizontally. Basement storm windows use a single window pane with thumb latches. 
• Interior storm windows: Interior storm windows fit inside your existing window. These storm windows are typically cheap and use a single pane of glass and a lightweight casing, such as vinyl or fiberglass. Interior storm windows are easy to install yourself.
• Temporary storm windows: These are clear acrylic or film panels that fit inside your interior window frames. You can easily install them using heat from a hair dryer to create an airtight seal. Unfortunately, they only last for roughly one season. 

Storm Window Materials

Storm window frames come in vinyl, fiberglass, aluminum, and wood. Storm windows also have many glass options. Glass with a Low-E coating is popular because it reduces heat transfer and is more energy-efficient. Below are other standard glass options for storm windows:

• One-and-one-eighth-inch thick glass pane
• Laminated glass
• Plexiglass
• Three-quarter-inch thick glass pane
• Tinted glass
• Tempered glass

Warranties

Window manufacturers include warranties on their products to protect your investment. Many warranties cover installation and workmanship, but this isn’t standard for storm windows because they’re so easy to install.

Many companies do include a manufacturer’s warranty, though. The length and stipulations of these warranties vary by product. High-end options, such as wooden windows, typically come with comprehensive warranties, while vinyl windows may have warranties as short as one to two years. 

Lifetime warranties are not standard in the windows industry, so finding an installer that offers one on its windows or doors is a secure investment.

Though storm windows are typically designed for DIY installation, using a reputable window installer can provide a more stress-free experience. Many companies offer window replacement and installation, but you’ll need to find a certified installer for the specific window brand you want.
