If you’re looking to add a touch of elegance to your home, an external plasterboard ceiling is a great way to do it. Plasterboard ceilings are popular for many homeowners because they are relatively easy to install and maintain. Plus, they offer a wide variety of design options to choose from.

What Are External Plasterboard Ceilings?

Plasterboard ceilings are an external plastering system that creates a level, even surface on ceilings. They are made from a plasterboard layer applied to the top of the ceiling joists. The plasterboard is then sealed with a layer of joint compound and left to dry.

What Are the Benefits of Using External Plasterboard Ceilings?

If you’re thinking about renovating your home or office, you may be wondering if an external plasterboard ceiling is the right choice for you. Here are some of the benefits of using an external plasterboard ceiling that you may not have considered:

1. Increased Insulation

Plasterboard is an excellent insulator, so using it on your ceiling will help to keep your home or office cooler in summer and warmer in winter. This can lead to significant savings on your energy bills.

2. Soundproofing

If you live in a busy area or have noisy neighbours, an external plasterboard ceiling can help to reduce the amount of noise that enters your home or office. This can be a great way to improve your quality of life and increase your concentration levels.

3. Fire Resistance

Plasterboard is a fire-resistant material that can offer protection against accidental fires. This can be particularly useful in commercial and industrial settings.

4. Easy to Install

External plasterboard ceilings are relatively easy to install. You can either have your plasterboard ceiling installed by a professional or do it yourself. However, it is always advisable to seek professional help if you are unsure how to install the plasterboard ceiling.

5. Affordable

Plasterboard ceilings are a highly affordable option when compared to other ceiling types. This makes them an ideal choice for commercial and industrial settings.

What Are the Most Common Issues of External Plasterboard Ceilings?

External plasterboard ceilings are a common sight in many homes and businesses. While they offer a clean, modern look, they can also be susceptible to several issues. Here are some of the most common problems with external plasterboard ceilings:

1. Cracks

One of the most common problems with plasterboard ceilings is the formation of cracks. These can be caused by some factors, including the settlement of the building, movement of the structure, or even just the weight of the plasterboard itself. In some cases, cracks may not be a major issue, but in others, they can cause the plasterboard to become detached or even collapse completely.

2. Water Damage

Another common problem with plasterboard ceilings is water damage. This can be caused by leaks from pipes or appliances or even rainfall if the ceiling is not properly sealed. Water damage can cause the plasterboard to swell, leading to cracks and even complete collapse. In addition, it can also lead to the growth of mould and mildew, which can be a health hazard.

3. Sagging

Sagging is another common issue with plasterboard ceilings. The weight of the plasterboard usually causes this, but it can also be caused by water damage or the settling of the building.

4. Collapse

Collapse is the most serious problem with plasterboard ceilings. This can be caused by several factors, including settlement of the building, movement of the structure, water damage, or even just the weight of the plasterboard itself. Collapse can cause serious injury or even death, so it is important to have any suspicious plasterboard ceilings inspected by a professional.


External plasterboard ceilings are a great way to improve the look of your home. They are also a great way to improve the value of your home.  However, it is important to maintain them properly as they are at risk for some issues if not taken care of properly. Make sure to consult with an expert before making any decisions.
