Dry walls, also known as plasterboard or gypsum board, are essential components of any modern building. They not only provide structural support but also play a vital role in regulating the temperature and humidity levels inside a house. In this article, we will explore the science behind how drywalls balance these two critical factors and contribute to creating a comfortable and healthy living environment for homeowners.
What are Dry Walls?
Dry walls are panels made of gypsum plaster sandwiched between thick sheets of paper. They are commonly used as interior walls and ceilings in residential and commercial buildings due to their smooth finish, ease of installation, and cost-effectiveness. Dry walls are also known for their fire-resistant properties, making them a popular choice for constructing wall partitions.
How Drywall is Made?
The manufacturing process of dry walls involves heating gypsum rock to high temperatures, crushing it into a fine powder, and then mixing it with water to form a paste. This paste is then poured between two thick sheets of paper, pressed together, and left to dry. The end result is a sturdy and lightweight panel that can be easily transported and installed in buildings.
Types of Drywall
There are several types of dry walls available in the market, each with its unique properties. The most common ones include regular, moisture-resistant, fire-resistant, and sound-proof dry walls.
Regular Drywall
Regular dry walls are used for interior walls and ceilings in areas where there is no risk of water or humidity exposure. They are affordable and provide a smooth surface for painting or wallpapering.
Moisture-Resistant Drywall
Moisture-resistant dry walls are treated with special additives to make them more resistant to water and humidity. They are commonly used in kitchens, bathrooms, laundry rooms, basements, and other high-moisture areas.
Fire-Resistant Drywall
Fire-resistant dry walls are made with fire-retardant materials and are designed to slow down the spread of fire. They can provide up to an hour of protection, giving residents enough time to evacuate in case of a fire.
Sound-Proof Drywall
Sound-proof dry walls contain extra layers of gypsum and other sound-absorbing materials, making them ideal for reducing noise transmission between different rooms or apartments.
How are Drywalls Installed?
Drywalls are installed by attaching them to a metal or wooden frame, commonly known as studs, using screws. This creates a hollow space between the dry wall and the existing wall, which acts as insulation and helps regulate temperature and humidity levels.

Cutting
Dry walls can be easily cut using a utility knife or a drywall saw. However, it is essential to wear protective gear such as gloves and goggles while cutting, as the fine dust from gypsum can irritate the skin and eyes.
Hanging
Hanging dry walls involves attaching them to the studs using screws and then covering the seams and screw holes with joint compound. Once the compound dries, it is sanded down to create a smooth surface for painting or wallpapering.
Finishing
The final step in installing dry walls is finishing, which involves adding a coat of primer and then painting or wallpapering the surface. This not only gives the walls a polished look but also protects them from damage and wear.
How do Drywalls Balance House Temperature?
One of the primary benefits of dry walls is their ability to regulate indoor temperature. The gypsum material used in dry walls has high thermal conductivity, meaning it can transfer heat efficiently. When warm air from the environment comes into contact with dry walls, the gypsum absorbs the heat and slowly releases it back into the room, helping to maintain a stable temperature. Similarly, during colder months, dry walls prevent heat from escaping through walls, making the house warm and cozy.
Energy Efficiency
Due to their insulating properties, homes with dry walls have lower energy consumption, resulting in lower utility bills. The hollow space created by the dry wall acts as an air barrier, preventing heat transfer between the interior and exterior of the house. This helps maintain a comfortable temperature inside the house without relying heavily on heating or cooling systems.
How do Drywalls Control Humidity Levels?
Dry walls also play a crucial role in maintaining optimal humidity levels inside a house. Gypsum has a high capacity for absorbing moisture from the air, which helps to reduce humidity levels in humid conditions. In contrast, when the air is dry, gypsum releases some of that moisture back into the environment, thus increasing humidity levels. This process of absorption and release helps to keep the indoor humidity at an ideal level for human comfort.
Other Factors Affecting Temperature and Humidity Balance
While dry walls play a significant role in balancing house temperature and humidity, other factors also contribute to creating a comfortable living environment. Factors such as insulation, ventilation, and air conditioning systems all work together with dry walls to maintain the right balance of temperature and humidity.
Drywall Alternatives
In some cases, dry walls may not be the best option for certain areas of a house. For example, in high-moisture areas such as basements or bathrooms, alternatives such as cement board or moisture-resistant paint may be more suitable.
Dry walls are more than just simple wall panels; they are vital components that help regulate temperature and humidity levels inside a house. Their unique properties make them well-suited for creating a comfortable and healthy living space for homeowners. Understanding how dry walls work can help homeowners make informed decisions when it comes to building or renovating their homes. So next time you see those plain-looking walls, remember the essential role they play in keeping your home comfortable and well-balanced.
