What TimberHP does

TimberHP (legally GO Lab, Inc.) is a U.S.-based manufacturer of high-performance wood fiber insulation, founded in 2016 by Matthew O'Malia and Joshua Henry and headquartered in Madison, Maine. The company operates the first North American facility at scale to produce dry-process wood fiber insulation, using a manufacturing process adapted from European technology. TimberHP converts abundant residual softwood chips—essentially byproducts of regional lumberyard activity—into three product lines: TimberBatt (flexible batt insulation for cavity applications, R-3.7 to R-4+ per inch), TimberFill (loose-fill and dense-pack insulation, R-3.4 to R-3.8 per inch), and TimberBoard (rigid continuous exterior insulation board launched in December 2025, R-3.4 to R-3.7 per inch). All three products carry ICC-ES evaluation reports validating compliance with IBC and IRC building codes and are Declare labeled and Red List Free; TimberBatt also holds a third-party verified EPD demonstrating that it stores more carbon than it emits across its lifecycle. The Madison facility, a revitalized former paper mill, contains three production lines and inherits an experienced workforce from the prior Madison Paper Industries operation.

TimberHP sells exclusively through a regional distributor and dealer network—lumber yards, building supply dealers, specialty insulation distributors, and preferred installers—rather than direct-to-consumer, with current coverage concentrated in the Northeast and Mid-Atlantic U.S. and expanding westward via territory sales managers covering OH/W PA, E PA, NJ, DE, MD, EMA, RI, CT, and NY. Customers are predominantly SMB residential builders, remodelers, and contractors (Clason Remodeling, KD Construction, Basciani and Sons), with select multifamily developers (Avesta Housing), architecture and design firms (JSA Design), and institutional buyers (Maine Audubon). Pricing is quote-based and not publicly disclosed; the company periodically runs rebate programs (up to $2,000) to drive adoption, and supports sales with technical resources, BIM objects, EPDs, and an educational webinar series ("Beyond R-Value").

TimberHP's recent financial history includes a Chapter 11 bankruptcy filing in March 2025 triggered by construction cost overruns exceeding $30 million on the Madison facility, followed by a June 2025 emergence with a $10 million DIP facility and a restructuring in which bondholders received most of the new equity and prior shareholder equity was cancelled. In April 2026, FTAI Infrastructure Inc. (managed by Fortress Investment Group) announced a strategic investment to support production ramp-up and North American expansion, joining existing investors BlackRock, the Finance Authority of Maine, and municipal bond investors. The company operates with 51–100 employees and continues to be led by co-founder Matthew O'Malia as President and CEO.

Core offering

TimberHP manufactures and sells a complete wood fiber insulation product line — TimberBatt (flexible batt insulation), TimberFill (loose-fill and dense-pack insulation), and TimberBoard (rigid continuous exterior insulation board) — produced at its Madison, Maine facility from residual softwood chips. The products are sold through lumber yards, building supply dealers, insulation distributors, and preferred installers to residential builders, multifamily developers, contractors, and architects across the Northeast and Mid-Atlantic U.S. for high-performance, sustainable building envelope applications.

Product overview

TimberHP offers a complete wood fiber insulation system comprising three distinct products: TimberBatt (flexible batt insulation for cavity walls and floors), TimberFill (dense-pack and loose-fill insulation for walls and attics), and TimberBoard (rigid continuous exterior insulation board). These products work together as a system, addressing different insulation needs in residential, multifamily, and commercial construction while delivering thermal performance, acoustic comfort, fire resistance, and vapor-open moisture management. All three products are manufactured in Madison, Maine from abundant residual softwood chips and are the first U.S.-made wood fiber insulation products available at scale.
