Welcome to Chicopee Welding & Tool, the leading expert in the field of business and consumer services. In this article, we will explore the reasons behind why double hung windows become drafty and provide comprehensive solutions to address this common issue. If you are experiencing draftiness in your windows, you've come to the right place!

The Mechanics of Double Hung Windows

In order to understand why double hung windows become drafty, it's important to grasp the mechanics behind their operation. Double hung windows consist of two sashes, namely the top sash and the bottom sash, which can be slid up and down independently. These windows provide ventilation and easy cleaning options, making them a popular choice for homeowners. However, over time, certain factors can contribute to their draftiness.

Causes of Draftiness

Poor Insulation

One of the primary reasons double hung windows become drafty is poor insulation. Over the years, the seals around the sashes may deteriorate, allowing cold air to enter and warm air to escape. Additionally, the insulation materials within the sashes can deteriorate, further compromising the effectiveness of the windows. At Chicopee Welding & Tool, we specialize in window insulation solutions that not only improve energy efficiency but also reduce drafts and increase comfort levels in your home or business.

Worn Weatherstripping

Another common cause of drafty double hung windows is worn weatherstripping. Weatherstripping is designed to create an airtight seal between the sashes and the window frame, preventing drafts. However, with time and exposure to the elements, weatherstripping can become worn, cracked, or loose. Our team at Chicopee Welding & Tool offers top-quality weatherstripping replacement services, ensuring your windows are properly sealed and protected against drafts.

Improper Window Installation

Improper window installation is another factor that can lead to draftiness in double hung windows. If the windows were not installed correctly or if gaps were left between the window frame and the wall during installation, drafts are more likely to occur. Our experienced professionals at Chicopee Welding & Tool have the expertise to identify and rectify any installation errors, ensuring a snug fit and optimal performance of your double hung windows.

Aging Window Frames

As double hung windows age, the window frames can deteriorate, leading to draftiness. Wooden frames may rot or warp, while metal frames can corrode or develop gaps. Our team at Chicopee Welding & Tool specializes in window frame repair and replacement, providing durable and long-lasting solutions to address the draftiness caused by aging frames.
