How it Works
Internal wall insulation, also known as drylining, involves applying insulation to the inside surfaces of external walls. It’s a practical and effective way to enhance your home’s energy efficiency, comfort, and thermal performance—particularly in retrofit projects.
By using rigid insulation boards such as PIR (polyisocyanurate), you can significantly reduce heat loss through walls. These high-performance boards work by slowing down heat transfer and lowering the U-value of the wall, resulting in better insulation, reduced heating costs, and a smaller carbon footprint.
Drylining is especially useful when external wall insulation isn’t possible, and it’s often used alongside external insulation to maximise energy savings. It’s a cost-effective solution that delivers long-term benefits in both energy efficiency and indoor comfort.

More Information
Got questions about Attic Insulation, grants, or the retrofit process? We’ve answered some of the most common ones below.
Most homeowners qualify if their property was built and occupied before 2011. Internal wall insulation grants are available under the SEAI Better Energy Homes Scheme, and Solfit can guide you through the full application and paperwork.
Internal drylining can reduce heat loss through walls by up to 30–40%, leading to noticeable savings on heating costs and a warmer, more comfortable home all year round.
- Installation time varies depending on the scale and scope of the work. We will outline a programme of work with you and advise on what is required in terms of clearing space and wall areas prior to installation.
- As the name suggests, internal drylining is carried out fully within the home. This involves attaching insulation and plasterboard to the internal walls of the house. While this is often a more affordable option of insulation, it should be noted that you will lose room space and will have to remove existing features such as shelving, cabinets and appliances to allow for the installation.
