Thermomass

What Thermomass does

Thermomass manufactures insulation systems for concrete sandwich wall construction using patented fiber-reinforced polymer (FRP) composite connectors produced via a proprietary pultrusion process, paired with rigid insulation products. The company offers five distinct systems targeting different construction methods: System NC for site-cast tilt-up, System SC for plant precast, System CIP for cast-in-place, System MP for modular precast, and System DW for European double-wall applications. Connector product lines include CC, MT, TL, MS-T, and AG Series, complemented by rigid insulation products including Styrofoam Gridboard XPS, Foamular Gridboard XPS, ISOMASS polyisocyanurate, and ISOGLASS polyisocyanurate insulation. The technology eliminates thermal bridging between concrete wythes while maintaining structural integrity, achieving the first ASTM E-119 4-hour fire rating on an integrally insulated sandwich wall using FRP connectors and holding ICC-ES and DIBT code approvals.

Thermomass serves precasters, contractors, and project owners across healthcare, education, corrections, government, industrial, agriculture/winery, recreation, and residential construction segments. The company employs a sales-led go-to-market model with regional sales managers covering U.S. regions plus Canada, Mexico, Europe, Latin America, China, Australia, and the Middle East, supported by a Technical Services team providing thermal analysis, specification assistance, and engineering support throughout the project lifecycle. Revenue is generated through hardware sales of connectors and insulation products bundled with professional services and complemented by AEC-accredited continuing education programs. Pricing is quote-based and not publicly disclosed.

Founded in 1980 by Robert T. Long in Cedar Rapids, Iowa, Thermomass was acquired by Meadow Burke (a CRH plc subsidiary) in September 2014 and joined with nine other construction accessories firms to form Leviat under CRH in November 2020. The Thermomass product brand continues to operate within Leviat's global construction accessories portfolio, maintaining dedicated sales, engineering, and technical services functions alongside sister brands Meadow Burke and Halfen.

Core offering

Thermomass manufactures patented fiber-reinforced polymer (FRP) composite connectors and rigid insulation systems (System NC, SC, CIP, MP, DW) used to build energy-efficient concrete sandwich walls for plant precast, site-cast tilt-up, cast-in-place, modular precast, and European double-wall construction. Products are sold to precasters, contractors, and project owners, with bundled technical services for thermal analysis, design assistance, specifications, and engineering support.

Product overview

Thermomass manufactures a comprehensive portfolio of concrete insulation systems for sandwich wall construction. The product line includes five distinct insulation systems (System NC for tilt-up, System SC for plant precast, System CIP for cast-in-place, System MP for modular precast, and System DW for double-wall applications), five types of rigid insulation products (Styrofoam Gridboard XPS, Foamular Gridboard XPS, ISOMASS polyisocyanurate, ISOGLASS polyisocyanurate), and five connector product lines (CC Series, MT Series, TL Series, MS-T Series, Series AG). These patented fiber-composite connectors and rigid insulation products work together to create energy-efficient concrete sandwich walls that eliminate thermal bridges. The systems are used across residential, commercial, industrial, and institutional construction projects worldwide.

Broad incumbents

• Oldcastle Infrastructure: A CRH plc subsidiary operating alongside Leviat, producing a broad portfolio of infrastructure and building products including precast concrete structures. Comparable as a much larger diversified CRH platform with adjacent product overlap in concrete building envelope systems.
• Meadow Burke: Sister company within Leviat (CRH plc) that acquired Thermomass in 2014. Manufactures and distributes a broad range of concrete construction accessories (lifts, anchors, forming hardware) used alongside insulated wall systems; comparable in parent-affiliation and distribution overlap, though broader in product portfolio.
• Halfen: Sister Leviat brand specializing in concrete anchoring and connecting technology, including insulated connector systems for precast facades. Directly comparable technology adjacency (anchoring and connecting concrete elements) under shared CRH plc ownership.

Direct peers

• Easi-Set Industries: Specialty precast concrete producer offering building envelope products including insulated precast wall panels. Comparable as a niche precast manufacturer competing for similar specification-driven non-residential construction projects.
• High Concrete Group: A leading North American architectural precast/prestressed concrete producer using insulated sandwich panel technology in healthcare, parking, and correctional construction. Operates as both a customer (specifier/integrator of Thermomass connectors) and a comparable peer with similar end-market project portfolios.
• Clark Pacific: California-based design-build manufacturer of architectural and structural precast concrete, including insulated wall panels for healthcare, education, data centers and parking. Comparable as a precaster that delivers integrally insulated sandwich wall envelopes with similar end-customer profile.
• AltusGroup (CarbonCast): AltusGroup is a North American alliance of precast concrete manufacturers that markets CarbonCast — insulated precast sandwich wall panels using carbon-fiber grid connectors that are structurally analogous to Thermomass's FRP wythe connectors. Direct head-to-head competitor for the same architect, precaster and code-official specification process.
• Nitterhouse Concrete Products: Mid-Atlantic producer of architectural and structural precast concrete including insulated wall panels. Comparable as a regional precaster with overlapping project types (commercial, institutional, multi-family) and comparable insulated wall envelope offerings.
• Spancrete: Producer of architectural precast, prestressed concrete and hollow-core plank with insulated wall panel offerings. Comparable as a precaster competing in the same specification-driven, energy-efficient building envelope market.

Emerging players

• Fox Blocks (a brand of Airlite Plastics): Manufacturer of insulated concrete forms (ICF) — an alternative insulated wall technology competing for the same energy-efficient building envelope specification. Not a direct FRP-connector competitor but addresses the same end-customer pain point (continuous insulation + structural wall) via a different assembly approach.
