CSR’s profits have jumped in the last year, up 143 per cent from a lively construction sector.

A rebound in residential construction activity has knocked up profits for one of the biggest names in building products.

CSR has reported a net profit of $72 million this financial year, up from $29.6 million the previous year.

But the company has not been without its worries, hit by tough trading conditions and a significant corporate restructure in recent years.

CSR managing director Rob Sindel announced the results last week, saying increased residential activity has trickled down through the corollary businesses in the CSR empire, including loss-making glass business, Viridian.

“Building products earnings increased by 20 per cent, with growth across most businesses, while the turnaround of Viridian is on track leading to a significant improvement in earnings,” he said.

The company say the building materials sector is looking strong, and that is it optimistic that residential housing will continue to grow.

Investors have seen a doubling in dividends to 10 cents per share.
