Saint-Gobain acquired SIG Roofspace Solutions, which designs, manufactures, and installs panelized roofing systems in the United Kingdom. Financial terms were not disclosed. This acquisition complements the portfolio of Saint-Gobain products in the country, accelerating the involvement in the off-site manufacturing construction market which already includes Pasquill roof-trusses, Scotframe timber-frame houses and Saint-Gobain steel-frame systems. RoofSpace is based in the Midlands, and achieved sales of around €20m in 2017.
