Why Walls in Old Houses Are Thicker Than You Think

Walls in old houses tend to be thicker than their modern counterparts due to differences in constructing methods. Homebuilders of past centuries employed a variety of techniques to ensure a home’s stability and longevity, and thicker walls were just one method employed. Here’s why walls were so thick in old houses:

Brick walls: The most luxurious homes of the past tended to be constructed of brick, which is a very durable material that provided excellent insulation. The thickness of the walls allowed for better temperature control and protection against the elements.

Plaster walls: Plaster walls were commonly used in homes before the advent of drywall. Plaster is a heavy, durable material and required thicker walls to support its weight.

No insulation: Older homes did not have insulation as we know it today. Thick walls served as the means of providing insulation and were necessary for keeping the home warm in the winter and cool in the summer.

No air conditioning: Before the widespread use of air conditioning, thicker walls provided insulation against heat and humidity, keeping the interior of the home more comfortable.

Noisy environment: Older neighborhoods were often filled with sounds of horse-drawn carriages, factories, and trains. Thicker walls provided a sound barrier and insulation against outside noise.

The thickness of the walls in older homes was a practical necessity of the time, and while not as common in modern constructions, they still provide a unique charm and appeal that many homeowners enjoy.

Why are walls so thick in old houses?

Old houses built during the 20th and 1930s are well known for their thick walls, which are noticeably thicker than those found in modern homes. While the reasons for their thickness are many, the main factor is the difference in construction methods. In this article, we’ll explore why walls in old houses are so thick, and the benefits of this thickness.

Construction methods of 20th century homes

During the 20th century, homes were constructed using methods that differ significantly from those used today. These old houses were typically built using load-bearing walls and structural systems made of brick or stone, which formed the foundation of the house. In contrast, modern homes make use of lightweight framing techniques that use less material and are more affordable. Another factor that contributed to the thickness of walls in old houses is the fact that many builders at the time used plaster and lath construction in which wood strips, called lath, were nailed to the wall studs and covered with multiple layers of plaster. This created a thick and sturdy wall that could withstand the test of time.

Exterior siding vs. brick construction

While both exterior siding and brick were used in the construction of old homes, brick was the material of choice for the more elegant and luxurious homes of the time. Brick construction offered numerous benefits, including increased durability and longevity. It also served as a natural insulator, keeping the house cool in the summer and warm in the winter.

On the other hand, homes made of wood or other exterior siding often required additional insulation and weatherproofing, adding to their thickness. As a result, many older homes made of wood may have walls up to 12 inches thick.

The durability of brick walls

Aside from the aesthetic benefits of brick, another reason why builders used this material in construction was its durability. Brick walls are known to last much longer than other types of walls, with some still standing after hundreds of years. This was especially important during the early 20th century when materials were not as readily available. Builders were forced to use the available materials in a manner that resulted in strong and sturdy structures that would last for generations.

Thermal insulation of thick walls

Thick walls in old houses provided excellent insulation from temperature fluctuations. This made them more energy-efficient, as they required less heating in the winter and cooling in the summer. Brick was especially effective in this regard, as it offered natural thermal insulation. Key point: Thick walls in old houses provide natural insulation to make them more energy-efficient.

Soundproofing benefits of thick walls

Another benefit of thick walls is their ability to block out sound. With the construction methods of the past, walls were built to be solid and sturdy. This made them an effective sound barrier that could help reduce the transmission of noise between rooms. Key point: Thick walls in old houses are an effective sound barrier that can help reduce noise transmission between rooms.

Aesthetics and practicality of thick walls in older homes

Thick walls in old houses were not just practical, but also aesthetically pleasing. They provided a feeling of solidity and permanence, which was highly valued by homeowners of the time. In many cases, thick walls were used decoratively to create visual interest and add depth to a room. Another practical benefit of thick walls is that they provide more room for electrical wiring and plumbing, making them easier to renovate. Key point: Thick walls provide both aesthetic and practical benefits, making them a valuable feature in older homes. In conclusion, the thick walls found in older homes were a result of the different construction methods used at the time. While modern homes may be more affordable and lightweight, the thick walls of old houses offer many benefits, including natural thermal insulation, soundproofing, and durability. The aesthetic and practical benefits of thick walls make them a valuable feature of homes built during the 20th and 1930s and for many, a desirable feature that they would love to have in their own home.
