WHY EXTERNAL WALL INSULATION?
Most mid-century homes in Blackrock, Monkstown, Mount Merrion, Stillorgan and Dún Laoghaire lose up to 35 % of their heat straight through solid walls. External wall insulation wraps the shell in 100–150 mm of EPS or mineral-wool, stopping draughts and raising indoor temperatures by up to 5 °C on like-for-like boiler use. Done right, you can expect a BER leap from “E” or “F” to A-rating and energy-bill cuts of 30 – 40 %.

Frequently Asked Question
-
Do I need planning permission?
Generally no, as EWI is considered maintenance, but protected façades may need a Section 57 declaration from DLRCoCo. -
Which insulation board is best — EPS or mineral wool?
EPS excels at affordability and low U-values; mineral wool wins on fire-rating and breathability. Both carry NSAI certification. -
How long does the job take?
A typical 3-bed semi completes in 3–4 weeks, weather-dependent. -
Will it change the look of my red-brick?
We can apply brick-slip cladding to match your original façade.
