How Thick Is Insulated Plasterboard

There are various types of plasterboard that can be used for insulation. Before you start working on it, it’s important to know its thickness. You will most likely have insulation between the drywall and the wall you’re planning on decorating. Although it’s common to add insulation between the plaster and brick layers of a house, the difference between a regular wallboard and an insulated one is significant.

Although a piece of insulated drywall can help speed up the installation process and give you more space, it’s also possible that the use of drywall and insulation can work better together. If you have limited space, you can opt for an insulated plasterboard instead of installing a thick layer of insulation. One significant disadvantage of using insulated drywall is that it can’t be completely controlled. This means that it won’t provide you with the same energy savings as using separate layers of insulation and plaster.

Types Of Insulated Plasterboard

A wide range of insulation options is available for use in combination with drywall. This product includes various types of core, such as phenolic foam, polystyrene, or PIR. You can select from a variety of setups depending on your project’s design. Also, these boards can be made to either standard or moisture-resistant specifications. The best and most popular thicknesses of these are 22mm, 25mm, and 62.5mm. The range of insulated drywall includes products from various brands such as Celotex, Kingspan, British Gypsum, Knauf, and Xtratherm.

Plasterboard Thicknesses

Although standard drywall comes in various thicknesses, insulated construction allows you to choose between various options. For instance, you can buy 12.5mm, 9.5mm, or 15mm thick standard drywall. You’re more likely to utilize the latter when it comes to drywalling. For ceilings only, 9.5mm is commonly used, though it can be used for walls if there’s a tight space.

In addition to being able to come in various thickness levels, insulated construction also has a wider range of uses. For instance, you can find this product in various ranges from 25 to 65mm. However, most of the thickness is actually the insulation, not the plaster itself. For instance, if you’re looking for a 12.5mm or 9.5mm thick product, the rest of the insulation will come down to the insulation.

Unlike regular drywall, insulated plaster can’t be controlled over your walls. The only choice for a base is the 12.5mm or 9.5mm thickness. The manufacturer then adds insulation to the plasterboard. Although insulated drywall may seem like an easier choice, it is actually more expensive to buy compared to buying separate insulation and a layer of plasterboard.
