Insulated plasterboard itself offers a level of moisture resistance, but it is not completely impervious to damp. Persistent damp issues should be addressed at the source to prevent long-term damage and ensure the effectiveness of your insulation. For areas prone to higher moisture levels, such as kitchens or bathrooms, we recommend opting for our moisture resistant plasterboard to provide an additional layer of protection. You can also seek the advice of professionals for more further guidance on this.
