Frequently Asked Questions
Does internal insulation make rooms smaller?
Slightly, typically by 60–120mm on each outside wall. It suits period homes where the outside can't be changed.
How much does internal wall insulation cost in Dublin?
Typically €6,000–€18,000. The exact price depends on access, the extent of the work and the materials needed.
When should I book internal wall insulation?
Plan it, ideally alongside other renovation work.
Are there SEAI grants for insulation?
Yes. SEAI offers grants for attic, cavity wall, internal and external wall insulation for qualifying older homes. Check seai.ie for current amounts and conditions.
Will insulation cause damp?
Not when it is installed properly with adequate ventilation. A ventilation check should be part of any insulation job.
Which insulation saves the most?
For most homes, attic and cavity wall insulation give the quickest payback. Solid-wall homes gain most from internal or external wall insulation.
