Understanding Asbestos in Old Apartments: A 1915 Example

When you live in an old apartment, especially one built before World War II, questions about materials and their composition can arise. One such query is whether asbestos drywall could have been present in a 1915 apartment. This article will explore the history of drywall and asbestos, and how they relate to old buildings in detail.

The Origins of Drywall: Post-WWII Innovation

Let's start by dispelling a common myth. Drywall, also known as plasterboard or blueboard, is a modern invention developed after World War II. This material was a significant improvement over the traditional method of constructing walls using lath and plaster, which was the norm in the early 20th century.

Initially, drywall was not widely used due to its high cost and the labor-intensive process required to install it. However, as manufacturing processes improved and the cost decreased, drywall became more popular. Today, it is the standard for interior wall construction in homes and commercial buildings.

No Asbestos in Drywall Before 1960

There is a popular misconception that drywall contains asbestos. The truth is, drywall is specifically designed to be asbestos-free. Asbestos was a material used in various building products before the 1980s due to its fire-resistant and insulating properties. However, the widespread use of asbestos in drywall only began in the post-WWII era, around 1945.

The transition from lath and plaster to drywall did not coincide with the introduction of asbestos. In fact, before WWII, there was no drywall, and therefore, no asbestos in drywall. As you do the math, if your 1915 apartment hasn’t been renovated since around 1960, it is highly unlikely to contain asbestos drywall.

What About Lath and Plaster?

Going back to what materials were used in 1915, lath and plaster were the norm. Lath is a wooden framework used to hold plaster, often made of wooden strips or wires. This method has been in use for centuries and was a common practice in the early 1900s.

Lath and plaster have a higher risk of containing asbestos because they were used in various construction projects well into the 1970s. While the majority of homes and buildings in the late 19th and early 20th centuries did not use asbestos in their construction, if your building has undergone remodeling since that time, asbestos could have been incorporated into the renovation.

Consequences of Asbestos Exposure

Understanding the history of asbestos and its presence in old buildings is crucial for your health and safety. Asbestos can cause serious health issues, including lung cancer, mesothelioma, and asbestosis, among others. While exposure to asbestos has been a concern for many years, the risks are directly related to the time when asbestos was used in construction.

Removing or repairing materials suspected of containing asbestos requires professional expertise and strict safety measures. DIY projects can expose you to dangerous levels of asbestos fibers, leading to potential health risks. If you suspect the presence of asbestos, contact a professional for sampling and testing.

Conclusion

In summary, drywall in a 1915 apartment does not contain asbestos unless the building was renovated after 1960. For older buildings, lath and plaster were the norm, and while these materials also had a risk of containing asbestos, it was not common until the 1970s.

To ensure your safety and the safety of your family, it is crucial to understand the materials used in your building and take necessary precautions if asbestos is discovered. Professional asbestos testing and removal should be handled by qualified experts to minimize health risks.
