The Importance of Weatherproofing Replacement Windows

Weatherproofing is a key part of the window installation process, and it is an important step that helps ensure long-term reliability and overall performance. As a leading window replacement contractor, Renewal by Andersen® of Atlanta would like to give you a closer look at this essential step in installation.

The Importance of Weatherproofing Replacement Windows

The Importance of Weatherproofing

The ideal windows should be airtight, and only allow air through when you open them. Airtight windows prevent rainwater, ice and other elements from seeping through your windows, and keep your interior living spaces warm and dry. This also helps ensure your windows are energy-efficient. You can’t enjoy the promised energy savings if you have windows that allow heat loss during winter or heat gain during summer. Both increase your indoor heating or cooling costs.

Proper Installation

At Renewal by Andersen of Atlanta, we know that proper installation is an important factor in the window replacement process. After all, no matter how well-built the replacement windows are, they can’t deliver on their promise if improperly installed. As our replacement windows are built to size, our installation team focuses on preserving the original window opening and performing necessary repairs.

Once the window opening is ready, the new windows are fitted, then carefully positioned, plumbed and shimmed even before we start drilling and putting the screws in place. In most cases, there is a slight gap between the frames and the window opening, and this is where it is most critical. The wrong procedure or choice of insulation may do more harm than good.

Filling the Gaps

Some window replacement companies fill these gaps by pushing pieces of sheet insulation into the gaps. The problem with this procedure is that it doesn’t fill the gaps effectively. Given that most of these insulation materials tend to clump when they come in contact with moisture, the material in your window gaps can easily deteriorate once rainwater leaks into those gaps.

At Renewal by Andersen of Atlanta, we use a special insulating foam that expands as it is injected into the gap. It penetrates even the tightest corners, creating an impenetrable, weatherproof seal that transitions from the wall to the window frame without any gaps. This space will then be covered by caps and trim that match the frame and sashes for a clean look. What you get are weatherproof windows that protect your home from any outside condition.
