A Maine manufacturer has inked a deal to expand the distribution of its wood-fiber insulation across North America. TimberHP announced recently that it signed a deal with CertainTeed Inc., a subsidiary of the French multinational firm Saint-Gobain. “It is a huge vote of confidence in our technology and our team at TimberHP to partner with a brand as innovative and impactful as CertainTeed,” said Joshua Henry, chief executive officer of TimberHP, which he founded with Matthew O’Malia. …TimberHP, a subsidiary of Belfast-based GO Labs, is the first U.S. company to manufacture wood-fiber insulation, a construction product long popular in Europe. …TimberHP began producing blown-in insulation last summer and is rolling out board and batten-type insulation this year. The Finance Authority of Maine and Maine Rural Development Authority recently awarded TimberHP $1 million in loans to support an expansion.
