Taking care of your plasterboards should be one of your top priorities. This is easier said than done, as there are many things that you need to be wary of. One of the most significant threats to your plasterboards is the weather. To help protect your plasterboards, it’s best to be as informed as possible. To help you out, here’s everything you need to know about plasterboards and weather.

Does Hot Weather Affect Plasterboards?

There is a lot of debate surrounding the effects of hot weather on plasterboards. Some people claim that hot weather can cause plasterboards to warp, while others say that this only happens if the boards are not stored or installed correctly.

There are a few things to keep in mind if you are installing plasterboards in a hot environment. Firstly, make sure that you allow the plasterboard panels to acclimatize to the room temperature for at least 24 hours before installation. Secondly, do not store the boards in direct sunlight or in a heated garage – instead, store them in a shaded, cool area.

If you are experiencing problems with warped plasterboards, it is likely that they were not stored or installed correctly. In most cases, warped boards can be fixed by re-attaching them to the wall using adhesive or screws.

Why Does Weather Affect Plasterboards?

Plasterboard is a common building material used to create walls and ceilings. It is made up of gypsum plaster, which is a soft mineral, and a reinforcing fiberglass mesh. When it is exposed to high humidity, the gypsum plaster can swell and cause the fiberglass mesh to break. This can lead to the plasterboard cracking and falling apart.

Weather can also affect plasterboard in other ways. Extreme temperatures can cause the gypsum plaster to shrink or expand, which can lead to the plasterboard becoming warped or distorted. Rain and snow can also seep into the plasterboard and cause it to become wet and damaged.

For these reasons, it is important to consider the weather when installing plasterboard. It is best to avoid installing it in areas that are exposed to high humidity, such as bathrooms and kitchens, and to make sure that it is properly sealed and protected from the elements.

How Do You Protect Your Plasterboards from Harsh Weather Conditions?

One way to protect your plasterboards is to install weatherstripping around the edges of the boards. This will help to keep out moisture and wind, which can damage the boards. You can also install insulation around the boards. This will help to keep them warm in the winter and cool in the summer. If you live in a particularly windy area, you may want to install a windbreak around your home. This will help to protect the plasterboards from being blown away. Finally, you can seal the plasterboards with a coat of paint or sealant. This will help to protect them from moisture and humidity.


Weather affects plasterboard in a number of ways. Temperature, humidity and air pressure can all cause problems for plasterboard installations. In addition, changes in weather can cause the plasterboard to expand or contract, which can lead to damage or even failure of the plasterboard.
