The term waterproof simply refers to high resistance to humidity and water in general. For a wall in a wet room, for example, waterproof plaster is an interesting solution: unlike BA13 board, water-repellent plasterboard is resistant to water vapour for years.
Of course, the price is also higher, due to its high efficiency against humidity.

Waterproofing plasterboard is a formidable weapon against humidity, a household menace

This is because humidity tends to seep into different rooms in the house, despite your efforts to air and ventilate. The consequences can range from discomfort to illness, allergies, deterioration of the property, and fungi growth. Waterproofing materials are designed to prevent interior humidity.

Waterproof plasterboard, ideal for damp rooms

In bathrooms, kitchens, toilets, or any other water room where humidity can quickly reach an excessive level, that is the best place for waterproof plaster. Waterproof plasterboard is most often used in rooms with the highest levels of humidity, such as the bathroom or shower room. And for a good reason!

It is not always easy to limit the presence of water vapor in the air in the bathroom so you might as well protect the partitions, walls, ceiling, and framed lining effectively with a material such as waterproof plasterboard.

Unheated and therefore cold areas such as garages, storerooms, cellars, and attics can also be affected by humidity. Protecting these rooms can therefore also be achieved with waterproof plasterboard and its resistance to humidity.
Carrying out work to install waterproof plasterboard can be complicated. Fortunately, most of the major brands have variations that fit into every corner of the bathroom or kitchen.

One thing is certain, neglecting the risks of moisture on partitions, walls or ceilings can be very harmful in the long run. It is better to invest and finance works to avoid any complication, even if it means paying the price…

What is the price of waterproof plasterboard?

Waterproof plasterboards are therefore of great interest for many rooms in the house, effectively combating damp. If the work is recommended, then what about the cost of the plates? Is the price worth it? That's the question… even if you suspect the answer!

Firstly, the price of the plasterboard itself

The price of waterproof plasterboard is usually between 3 and 8 pounds per square metre. The type of plasterboard required will affect this price, for example, plasterboard for a ceiling will cost more than a vertical partition.

Secondly, the price of the installation of the plate

Although you can install your waterproof plasterboard, it is advisable to refer to a professional. If you want to install your plates, you will still need to buy the installation equipment.
To hire a plasterer (yes, that's the name of the professional plasterboard installers, among others), expect to pay around 30 to 40 pounds per square metre of plasterboard. At least you don't take any risks with the installation of your plates!

Much more than a simple insulation material, waterproof plasterboard is a genuine barrier against humidity. The price of the installation is therefore much more important than the price of the plasterboard itself. Do not hesitate to get an estimate from different professionals before committing yourself. The price of waterproof plasterboard varies little, but the price of installation can make a difference.
