Maria McGrane2024-05-29OS Holding recently completed a renovation of my kitchen/dining area and I couldn't be happier with their work. The job involved knocking down a load-bearing wall, installing steel supports, taking up the old floor and laying a new one as well as skirting boards. They also did the plumbing and electrical works, connected new radiators and did the painting to finish. The guys are very skilled in all aspects of their work and they are careful to fulfil all requests. They are also very tidy. I'm especially happy with the meticulous way the herringbone floor was laid. Vadim is easy to work with as he listens to what you say a a client and is always prompt to respond to calls and emails. I would have no hesitation in recommending OS Holding and I intend to contract them again when I get round to doing my attic!

Best Insulation for Interior Walls

Internal wall insulation offers a straightforward solution to heat loss, providing homeowners with a warm, comfortable environment while reducing energy bills.
This option is particularly effective for homes with solid walls or for those looking to maintain the exterior appearance of their property.


What Makes Internal Wall Insulation Essential?
Heat loss through walls is one of the primary culprits behind high energy costs and fluctuating indoor temperatures. By adding a layer of insulation to your interior walls, you can significantly improve your home’s thermal performance.
Internal wall insulation helps retain warmth during colder months and keeps interiors cooler in summer, ensuring year-round comfort.

Frequently Asked Questions
What is internal wall insulation?
Internal wall insulation involves adding insulated boards or layers to the interior walls of your home to reduce heat loss. This method is particularly effective for homes with solid walls that lack cavity insulation.
How does internal wall insulation improve energy efficiency?
By creating a thermal barrier, internal wall insulation traps heat within your home, reducing the need for constant heating. This results in lower energy consumption and decreased utility bills.
Is internal wall insulation suitable for all types of properties?
While it works best for older homes with solid walls or heritage buildings where exterior insulation is not feasible, it can also enhance energy efficiency in modern homes with poorly insulated walls.
Will internal wall insulation affect the appearance of my home?
Internal wall insulation preserves the exterior look of your home. Inside, the walls may lose a small amount of space due to the added insulation boards, but this is minimal.
Can internal wall insulation help prevent damp and mould?
Yes, it reduces condensation on interior walls, which helps prevent the growth of damp and mould. This contributes to a healthier indoor environment.
How long does the installation process take?
The timeline depends on the size of your property and the scope of the project, but most installations are completed within a few days. OSBER ensures minimal disruption during the process.
Are there any financial supports available for internal wall insulation?
Yes, homeowners in Ireland may qualify for SEAI grants of up to €2,400 to help cover insulation costs. OSBER can assist you with the application process to maximise your savings.
Will I need to redecorate after installation?
After installation, walls are skimmed and prepared for painting or other decorative finishes. You’ll need to redecorate, but the final results will be a smooth and ready-to-use surface.
How much space will I lose with internal wall insulation?
The space loss is minimal, typically a few centimetres per wall. This is a small compromise for the significant energy savings and improved comfort.
Can internal wall insulation increase my home’s value?
Yes, by improving your home’s energy rating and thermal comfort, internal wall insulation can enhance its overall market appeal and value.
