Revenue at building materials company Kingspan was 4% higher in the first six months of the year, according to the company, at €889.3m.
Earnings before interest, tax, deductions and amortisation were also up, rising 17% to €88.9m.
The company said it continued to have a strong order book due to demand for low energy buildings, despite the generally weak economic picture.
The recovery in Britain – a market that represents 38% of Kingspan’s sales – helped the company in that market, while sales in mainland Europe also grew despite weaknesses in a number of other markets.
In Ireland, Kingspan said volumes had been improving gradually from a low base, however prices remain under “significant pressure”.
The company also saw encouraging activity in the North American and Australasian markets during the six month period.
