IHS Global Insight, Lexington, Mass., Residential construction activity will begin to see improvement in 2010, while nonresidential construction activity will not recover until 2011, according to the Second Quarter U.S. Building Materials Briefing by IHS Global Insight’s Building Materials Forecasting Service. Total building materials spending contracted by 1.02 percent in the first quarter of 2010 and is not expected to see positive growth until the last quarter of 2010. IHS Global Insight expects robust growth in materials predominantly used in residential construction, such as hardware, insulation and paint as growth returns to the residential construction industry. However, residential building materials will remain below 2006 peak and the recovery will be uneven. Nonresidential building materials, which were aided by the stimulus package, will continue to contract through the first quarter of 2011. And within the nonresidential building material sector, materials most intensively used in renovation activities will benefit earlier from the eventual recovery.
