What are impact windows?

Definition and purpose of impact windows

Impact windows, also known as hurricane-resistant or storm windows, are specially designed windows that are built to withstand severe weather conditions, such as hurricanes, strong winds, and flying debris. These windows are made with reinforced glass and durable frames to provide protection against high-velocity impact and to prevent the shattering of glass in the event of a storm or other extreme weather. The purpose of impact windows is to enhance the safety and security of residential and commercial buildings during hazardous weather events.

Types of impact windows

There are several types of impact windows available in the market, each with its own set of features and advantages. The most common types include:

  1. Single-hung impact windows: These windows have one movable sash, typically the bottom one, while the top sash remains fixed. They are a popular choice for both residential and commercial buildings.
  2. Double-hung impact windows: These windows have two movable sashes, allowing for increased ventilation and flexibility in opening and closing. They are often favored for their aesthetic appeal and versatility.
  3. Picture impact windows: These windows are fixed and do not open. They are commonly used in areas where visibility and natural light are the primary considerations.
  4. Casement impact windows: These windows open outward, similar to a door, and are usually operated with a crank. They offer excellent ventilation and are a preferred choice for areas with limited space.
  5. Sliding impact windows: These windows have horizontal tracks that allow the window to open from one side to the other. They are popular for their ease of operation and space-saving design.

Depending on the specific needs and preferences of the building owner, impact windows can be customized in terms of size, shape, color, and frame material.

Factors affecting installation time

The time required to install impact windows can vary depending on several factors. Here are some key considerations:

Window size and quantity

The size and number of windows being replaced or installed directly impact the overall installation time. Larger windows or a higher quantity of windows will naturally take longer to install compared to smaller or fewer windows. Additionally, if the windows need to be custom-made to fit specific dimensions, it may add to the installation time as well.

Type of installation method

There are two primary methods for installing impact windows: retrofit installation and full-frame installation. Retrofit installation involves removing the existing window’s sash and attaching the impact window to the existing frame. This method is generally quicker and less invasive, as it does not require the complete removal of the existing frame. On the other hand, full-frame installation involves removing the entire window unit, including the frame, and replacing it with a new impact window. This method may take longer as it requires more extensive work.

Accessibility and condition of existing window frames

The accessibility and condition of the existing window frames can also affect the installation time. If the frames are in poor condition or require repairs, additional time may be needed to prepare them for the installation. Similarly, if the windows are located in hard-to-reach areas, such as high-rise buildings or tight spaces, it may increase the installation time as well.

Pre-installation preparations

Before the actual installation process begins, several preparations need to be made to ensure a smooth and efficient installation. These preparations include:

Measuring and inspections

Accurate measurements and thorough inspections of the existing windows and frames are essential to ensure proper fitting of the impact windows. This step helps to determine the size and specifications of the new windows and identify any potential issues or repairs needed before installation.

Removing the old windows

If replacing existing windows, the old windows need to be carefully removed to make way for the new impact windows. This process involves removing any screws or fasteners, detaching the sashes, and carefully removing the frame. Proper care should be taken to prevent any damage to the surrounding walls or structures during this step.

Preparing the window openings

After the old windows are removed, the window openings need to be prepared for the installation of the impact windows. This includes cleaning the opening, removing any debris or obstructions, and ensuring that the opening is structurally sound and free from any water or moisture damage.

Installation process

Once the pre-installation preparations are complete, the actual installation process can begin. The installation process for impact windows generally involves the following steps:

Setting up the window frame

If a full-frame installation is chosen, the existing window frame is completely removed and replaced with a new frame that is designed to accommodate the impact window. The frame is securely attached to the surrounding wall or structure to ensure stability and proper alignment.

Sealing and securing the window

Before the impact glass is installed, the window frame is sealed to create a watertight and airtight seal. This helps to prevent any water or air leakage and enhances the energy efficiency of the window. Additionally, the frame may be reinforced with additional materials, such as aluminum or steel, to provide extra strength and durability.

Installing the impact glass

Once the frame is prepared, the impact glass is carefully fitted into the frame and secured in place. The glass may be secured using adhesive or mechanical fasteners, depending on the specific window design and installation requirements. The installation process ensures that the glass is properly aligned and sealed to provide maximum protection against impact and external elements.
