About

A little more about us

B. Donaghey and Sons Ltd are external wall Insulation contractors. We are backed by over 50 years experience in the construction industry.
We realise that many Irish houses, particularly those built before 1980, are very wasteful of energy. Various cost-effective energy saving opportunities exist which, through reducing fuel and electricity bills, can pay for themselves in a relatively short time.
