Internal Dry Lining

Internal Dry Lining

Internal dry lining insulation is an effective way to improve the energy efficiency of your home by insulating the inner surfaces of external walls. Ideal for older homes without cavity walls, this method involves fixing insulated plasterboard directly to the inside of external walls, reducing heat loss and improving comfort.

At CosyFill, we offer expert internal dry lining services using high-performance insulation boards that enhance thermal performance while maintaining a neat interior finish. If you're upgrading your home’s insulation, you may qualify for an SEAI grant of up to €4,500 under the Better Energy Homes Scheme.

Our team takes care of the entire grant application process—from assessment to paperwork and approval—so you don’t have to worry.

Benefits of internal dry lining:

• Reduce heat loss by up to 40%

• Save €400–€700 per year on energy bills

• Improve home comfort and air quality
