Cavity Wall Insulation


Is insulating my cavity walls cost effective?


Cavity Wall Insulation is one of the most effective and cost efficient ways to insulate new or existing buildings. At present, the majority of homes in Ireland do not have sufficient insulation and heat is allowed to escape far too easily. This means less comfort in the home and expensive heating bills.

Why chose West Coast Insulation to insulate my cavity walls?


West Coast Insulation can significantly improve existing homes and provide the highest standards of insulation in new buildings.


What do you use to insulate my cavity walls?


We use EcoBead Platinum bonded cavity wall insulation, our experienced team fill the cavity wall which prevents heat from escaping through the wall. A specially designed glue is sprayed on the bead as they are injected and this allows the bead to set in a mass in the wall.

Why should we use EcoBead to insulate our cavity walls?


EcoBead Platinum is a premium insulating bead and gives the highest performance and u-value available in Ireland. Manufactured by Aerobord Ltd Limerick, all contractors for EcoBead are regulated and audited by Aerobord and the National Standards Authority of Ireland.

Are there Grants Available for Cavity Wall Insulation?


Yes there is a €400 SEAI Energy Upgrade grant for Cavity Wall Insulation. See our Grants Page

Day 5 of the black out after a storm and thanks to our insulation we are warm in the house. We don't even have a stove or fire only candles lit and we are warm. This is the best upgrade investment we've made to our house.

Kudos to these guys. They came out, lifted the roof tiles to 3 roofs with no access and for the first time I saw how bad the insulation was in there (some had no insulation....) They topped up my attic insulation, re-floored and pumped the cavity wall in both my house and garage. Highly recommended this team, great team spirit on site.

We were looking to get our cavity walls insulated and heard about West Coast Insulation from a friend who had their house done in Galway. They had got their attic insulated with Rockwool and walls with ecobead bonded bead insulation and were very pleased. So we gave West Coast Insulation a call and they did a great job and the house is a lot warmer now; saved a fortune on oil, this winter. We would recommend West Coast Insulation to anyone looking to get their attic insulation or cavity wall insulation in the Galway Mayo area. John was very helpful and sorted out the grant paperwork also.
