Storm Window Glass / Hurricane Window Glass

In modern homes, they are used to improve their thermal insulation and soundproofing. Aside from insulation, storm windows provide strong protection against damage to expensive glass panes during inclement weather such as hail.

The cost of replacing a single-pane window with a double-pane window containing high-performance glass can be higher. Apart from this option, there is also the option of installing low-emissivity (Low-E) storm windows. Installing interior or exterior energy-efficient storm windows has the same benefit. Storm windows help reduce air movement in and out of existing windows, improve comfort, and reduce heating and cooling costs.

Low-E Storm Windows

Older storm windows are usually found only in clear glass, and newer models are available with a low-E coating that is capable of reducing heat transmission. Low-E Storm windows offer the advantage of more insulation. Such windows are useful in reflecting the winter heat and also help keep the house cool during summer to make the house more comfortable.

Modern storm windows are not like old storm windows. It does not need to be cleaned or removed to enter or exit. The new Low-E Storm is purpose-designed to blend in with the existing architecture and is permanently fixed. These windows are available as fixed or operable units.

Internal Storm Windows Vs. External Storm Windows

The interior and external storm windows have similarities in their energy saving. External models provide the benefit of actual storm protection for the window. They are useful for surviving and protecting external factors such as wind, rain, and snow.

The interior window is easier to install, remove, and clean and provides better seals for more energy efficiency.

The exterior storm window is permanent, so it does not go away, while the “permanent” interior storm window is also easy. The inside storm window becomes a cost-effective and versatile option.

Storm Window Installation

The process of Installing Storm / Hurricane Windows is shown below.

The window and the nearest surface should be checked. Before installation, it is necessary to see problems such as glass, rotten wood, broken parts, and water leaks.

Order the custom storm window of the new storm window measurement.

Measure the width between the inside edges of the window casing.

1. At the bottom, above
2. In the middle of the window
3. Measure the height from the top of the window casing to its highest point.

If horizontal sizes differ, order a new custom storm window when ordering the smallest size window.

A list of items requiring items is shown below.

  1. Storm window
  2. Measure tape
  3. Screwdriver
  4. Putty knife
  5. Caulk
  6. Caulking gun

After collecting all the materials, installing the window can be processed by following the steps.


Step 1. Make sure the storm window is appropriate for the opening. The top of the storm window should be determined by checking the direction of the movable panels. Keeping the storm window in the opening and checking if all the screw holes land on the wood is necessary.

Step 2. If there is an old window, remove it.

Step 3. The top and sides of the existing window opening should be coke. Considering that the bottom is not to close.

Holding the Caulking gun at an angle of 45-degree on the edge of the storm window, using a “pulling” motion, holding the gun at a constant angle. The caulk is to slide the tube nozzle with the joint while pressing the trigger of the gun.

Step 4. Start the process of changing the Storm window to the opening.

Ensure the opening is pushed tightly to the top of the storm window.

Step 5. Now, the storm window has to be secured in a window frame.

Using a screwdriver and screw, the upper corners of the window are temporarily secured and not fairly tight.

Step 6. The expansion should be adjusted below the storm window.

A typical Storm Window comes with a window sill expander. It helps to allow the bottom (approximately ½ inch) of the storm to meet the angular seal of the window opening. Tightly lower the adjustable expand against the windowsill with a putty knife. See that the expansion also contacts around the bottom.

Step 7. Install the rest of the installation screw after squaring the window unit.

Be careful whether the distance between the window and the frame is the same. (The ideal gap should be 1/16 inches on each side of the window).

Storm Window Replacement

Many factors should be considered before changing a window.

Generally, if you want to upgrade any kind of home, this is an important question regarding how much the budget is. If there is no money problem, windows other than the Storm window can be selected. If the money is tight, the Storm window becomes a good option.

The replacement storm window is usually installed outside the house on the standard single pen window. This window does not open or close. By creating a solid seal, they help improve insulation in the home and provide protection against outside elements.

The single pen window allows cool air and hot air to go out, which is why many prefer to change these windows.

If the existing window is 30 years or older and does not have to be removed for architectural purposes, the storm window should be installed in the outer part. Doing so will increase the life expectancy of the inside window.

It is advisable to seek the help of a professional experienced if the Storm Window is selected as a replacement option.

Storm Window Replacement Cost
