Larson Exterior Storm Windows

October 29, 2020

Storm windows are a budget-friendly way to not only increase energy savings, but also offer an economical option for adding living space to your home.

1. Increased Energy Efficiency

Adding a LARSON Storm Window will help keep your home warm in the winter and cool in the summer. Storm windows reduce infiltration of outside air, helping your HVAC system use less energy to maintain your desired air temperature. Not only will you feel more comfortable in your home, you'll lower your energy usage, keeping the environment healthier.

  • Save $26 in energy savings for every window, every year.*
  • Save up to 10% in heating and cooling costs by covering your opening with storm products.*

*NOTE: Low-E glass is now available on all LARSON storm windows.

2. Improved Curb Appeal

Add a storm window in a complementary color to add definition to your window opening or use one of our four common colors to match your existing window trim.

3. Add a Protective Layer of Insulation

Storm windows add air space between your primary window and the storm windows, which helps keep out dust, wind, and other harmful elements. The additional layer also helps quiet sounds from busy streets, loud neighbours, and barking dogs.

4. Increased Living Space

Storm windows provide a budget-friendly way to add three-season rooms and enclosed porches. LARSON Premium windows are an excellent choice for 3-season rooms and porch enclosures because of their overlap mount.

5. Easy Installation

Using only caulk and a screwdriver, storm windows can be mounted to existing window openings in just a few minutes.
