Combined, those four companies represent approximately $53 million in annual revenue. They are on the heels of TopBuild’s much bigger $1 billion purchase of insulation distributor SPI that completed in October $810 million purchase of Progressive Roofing that completed in July.

Commenting on the additions, TopBuild President and CEO Robert Buck said in a news release: “For our Specialty Distribution segment, Insulation Fabrics and Performance Insulation Fabricators expand our insulation accessory and mechanical insulation product offerings, while Diamond Door Products better enables us to meet our commercial and industrial customers’ metal building needs and bundle value-added solutions for them. For our Installation Services segment, L&L Insulation expands our geographic reach in the mountain states.”
