Understanding Double Pane Windows

Before we delve into the details of hurricane-proof windows, it’s essential to understand the concept of double pane windows. Double pane windows, also known as double glazed windows, are made up of two panes of glass separated by a layer of air or gas, typically argon or krypton. These windows are designed to provide insulation and improve energy efficiency in our homes.


Double pane windows consist of two layers of glass with a spacer in between, creating a sealed unit. The spacer is usually made of aluminum or other materials that provide structural support and help maintain proper spacing between the glass panes. The sealed unit is then installed within the window frame, creating an airtight space between the glass layers.

Insulating Properties

The main advantage of double pane windows is their insulating properties. The layer of air or gas between the glass panes acts as a barrier, reducing the transfer of heat between the interior and exterior of our homes. This helps to keep our homes cooler in the summer and warmer in the winter, resulting in energy savings and increased comfort.


In addition to their energy-saving benefits, double pane windows offer other advantages. They can help to reduce outside noise, creating a more peaceful and quiet indoor environment. Furthermore, these windows can also provide UV protection, blocking harmful UV rays that can fade furniture, carpets, and other interior furnishings over time.

Benefits of Double Pane Windows

Now that we have a better understanding of double pane windows, let’s explore some of their specific benefits.

Energy Efficiency

One of the most significant benefits of double pane windows is their energy efficiency.

This means that our heating and cooling systems don’t have to work as hard to maintain a comfortable indoor temperature, resulting in lower energy bills.

Noise Reduction

Another advantage of double pane windows is their ability to reduce outside noise. The layer of air or gas between the glass panes acts as a buffer, absorbing and dampening sound waves. This can be especially beneficial if we live in a noisy neighborhood or near a busy road, as it can help create a quieter and more peaceful indoor environment.

UV Protection

Double pane windows also offer UV protection. The two layers of glass in these windows help to block harmful UV rays from entering our homes. UV rays can fade and damage our furniture, carpets, artwork, and other interior furnishings over time. By installing double pane windows, we can help preserve the longevity and condition of our belongings, while also protecting our skin from the damaging effects of UV radiation.

Misconceptions about Double Pane Windows

Although double pane windows offer numerous benefits, there are some misconceptions that need to be addressed.

Confusion with Hurricane-proof

One common misconception is that all double pane windows are hurricane-proof. While it’s true that hurricane-proof windows may incorporate double pane technology, not all double pane windows are designed to withstand the extreme conditions of a hurricane. Hurricane-proof windows are specifically engineered to meet stringent impact resistance and design pressure ratings, as previously discussed.

Importance of Proper Installation

Another misconception is that once double pane windows are installed, we don’t need to worry about their maintenance or proper installation. However, proper installation of double pane windows is crucial for their performance and longevity. Improperly installed windows can result in air leaks, moisture infiltration, and reduced energy efficiency. Therefore, it’s essential to choose a reputable and experienced window installer who understands the specific requirements of double pane windows and follows proper installation techniques.

Types of Hurricane-proof Windows

Now that we understand the differences between hurricane-proof windows and double pane windows, let’s explore the various types of hurricane-proof windows available.

High-Impact Glass

High-impact glass windows are constructed using multiple layers of glass with a clear or tinted interlayer between them. These windows are incredibly durable and can withstand the impact of flying debris during a hurricane. If the glass does break, the interlayer helps to hold the shattered glass in place, reducing the risk of injury and preventing further damage to the property.

Hurricane Shutters

Hurricane shutters are another type of hurricane-proof window option. These shutters are installed on the exterior of the windows and can be closed to provide an additional layer of protection during a hurricane. They can be made from various materials, including metal, impact-resistant glass, or polycarbonate. While hurricane shutters do not offer the same visibility and aesthetics as other window options, they provide excellent protection against flying debris.

Laminated Glass

Laminated glass windows consist of multiple layers of glass bonded together with a layer of polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA) interlayer. This interlayer helps to hold the glass together when it breaks, similar to high-impact glass. Laminated glass windows are highly resistant to impact and can withstand the forces of a hurricane.

Impact-resistant Film

Another option for hurricane protection is impact-resistant film. This film is applied directly to the existing windows, creating a strong barrier against the impact of flying debris. While impact-resistant film may not provide the same level of protection as other window options, it is a cost-effective and temporary solution that can be applied in preparation for a hurricane.
