Best Storm Windows and Interior Storm Inserts for Maximum Energy-Efficiency

• Type: When choosing a storm window, consider your window type, the weather in your area and your budget, suggests Sibley.
• Material: Choose a durable material such as aluminum or vinyl, says Sibley. Also, look for options with multiple panes of glass, he adds.
• Energy efficiency: Consider energy-star certified windows and look for low-emissivity (Low-E) coatings to reduce heating and cooling costs, advises Sibley.
• Appearance: “Pick a window that complements your home’s appearance and suits its overall style,” says Laniado. “Remember, curb appeal is always a significant factor for potential home buyers in the future.”
• Installation: “Some manufacturers may require professional installation to validate a warranty,” warns Sibley. “Hiring a professional may also provide insurance coverage in case of accidental damage during installation.”
• Fit: Ensure the storm windows are the correct size and shape to fit your existing windows snugly. This is necessary to provide effective protection against the elements.

Types of Storm Windows

• Exterior storm windows: According to Sibley, these windows, installed on the outside of existing windows, offer the “best option for maximum protection against the elements and improved energy efficiency.” They extend your window’s lifespan and boost curb appeal. However, they are pricier and may need professional installation, he notes.
• Interior storm windows: This version is installed inside existing windows. “These are best for cost-effective insulation without altering the exterior appearance,” says Sibley. Easy installation is a plus, but they are less effective against drafts and may require more maintenance, warns Sibley.
• Temporary storm windows: Sibley says you can install these windows seasonally or as needed. “They’re best for temporary insulation, renters or short-term needs,” he explains. They are very affordable, reusable and easy to install and remove,” he adds. But remember, they offer less insulation and are not as durable.
• Disposable storm windows: This is the way to go for short-term insulation at an affordable cost. “They are made of a plastic film and attached with adhesive tape,” explains Sibley. He adds that while easy to install, this option is less durable, may require frequent replacement and obstructs visibility.
