New Zealand: Fletcher Building, New Zealand's largest building company, has spent US$4m and taken almost two months to replace the roof of its Christchurch wallboard factory that contained asbestos.

The Winstone Wallboards factory in Christchurch was reopened on 21 October 2013 following its closure on 27 August 2013 after traces of asbestos were found during preparations for the roof replacement. The new roof is expected to be completed by 8 December 2013.

Staff were transferred to the distribution centre or to Auckland during the closure and remained on full pay. Dispatch operations at Christchurch were down for three days, with wallboard supplied from Fletcher's Auckland plant during that time.

US/Canada: Georgia-Pacific plans to 'idle' one wallboard plant in Caledonia, Ontario and one wallboard plant in West Memphis, Tennessee in early 2014. Eric Abercrombie, a spokesperson for Georgia-Pacific, attributed the decision to production optimisation and a slow recovery in the building materials market.

"We are doing this because of market conditions and the fact we've just acquired new capacity through a merger," stated Abercrombie to local media. 60 employees will be affected at the Caledonia plant and 39 employees at the West Memphis plant.

In early 2013, Georgia-Pacific acquired four new gypsum wallboard plants when it took over Memphis-based Temple-Inland Building Products from International Paper. That deal, worth US$750m, added 1800 employees to Georgia-Pacific and 16 production facilities.

UK: A range of British Gypsum plaster and plasterboard solutions have been used in a contemporary housing complex developed by Taylor Wimpey's North Thames regional business in Welwyn Garden City, Hertfordshire, to help the house-builder meet thermal and acoustic requirements. The large-scale new-build development includes 159 apartments and 50 three-storey terraced houses.

"Due to the size of the project and the strict timescales we were working to, we needed a solution that required as little labour as possible. Drylyner TL was easy to use and really simplified the installation process from start to finish," said Tony Butcher, senior project manager at Taylor Wimpey North Thames.

For ease of application and speed, British Gypsum DriLyner Thermal Laminate (TL), a wallboard masonry lining system, was used on partitions and separating walls. The system offers a quick and easy solution to drylining brick, block and concrete walls by utilising adhesive dabs to bond the wallboard onto the walls. This meets the acoustic performance requirements in accordance with Part E of the UK Building Regulations, to provide superior sound insulation.

For further acoustic performance, Gyproc Soundcoat Plus was used on the partition walls in both the apartments and terrace houses. This coat is a gypsum based compound that is designed to seal masonry walls prior to drylining, was used to minimise air leakage through cracks and unfilled joints, improving energy efficiency and limiting noise pollution.

In keeping with the sustainability focus of the project, Taylor Wimpey took advantage of the British Gypsum Plasterboard Recycling Service in order to minimise the environmental impact of the project.

"The Plasterboard Recycling Service was a great help. It was a cost-effective recycling option that not only saved us a lot of time and effort, but also helped us meet our sustainability objectives. British Gypsum supplied the skips we needed for the waste products and took them away to be recycled at its onsite recycling facility," said Butcher.

New Zealand: The New Zealand government is considering cutting import duties on home building materials to help reduce rising house prices in the country.

"Building material costs are too high and can be as much as 30% more in New Zealand than in Australia according to the Productivity Commission. The industry needs a shake-up through increased competition and greater transparency to ensure kiwi families can get access to more fairly priced building materials and homes," said Housing Minister Nick Smith in a statement.

Smith and Commerce Minister Craig Foss released an options paper outlining possible measures to curb the cost of house construction. The paper said that 19% of the output of the home construction industry was made up of imported content. Tariffs notionally still applied to most items used in housing construction, such as wallboard, insulation, timber products, steel and aluminum joinery, particle board and roofing materials, but adjusted tariffs - the duty as a percentage of the value - were small and diminishing due to free trade agreements. Submissions to the options paper close on 18 December 2013.

New Zealand has imposed anti-dumping duties on imports of plasterboard from Thailand since 2011, wire nails from China since 2011 and reinforcing steel bar and coil from Thailand since 2004.
