What Rmax does
Rmax is a US-based manufacturer of polyisocyanurate (polyiso) rigid foam board insulation, operating as a business unit of Sika Corporation, the US subsidiary of the Swiss specialty chemicals group Sika AG. Founded in 1978 and headquartered in Lewisville, Texas, Rmax produces a portfolio of continuous-foil-faced and specialty-faced insulation boards designed for commercial, residential, and below-grade building envelope applications. Core product families include ECOMAXci FR, Thermasheath, Durasheath, TSX-8510, R-Matte Plus-3, Below Grade, ThermaBase-CI, ECOMAXci FR Ply, and Thermasheath-SI, each engineered for specific performance criteria such as fire rating, structural use, or compatibility with cladding assemblies.
The company sells primarily to commercial and residential builders, contractors, architects, and OEM/offsite construction customers, with distribution executed through a hybrid direct sales model — regional account executives embedded in field offices — combined with retail and distributor channels. Pricing is project-specific via quote, with longer-term multi-year contracts referenced as a purchasing option. Rmax supports specification-stage demand with AIA/CES-approved continuing education courses for architects and offers installation training through the ABAA, indicating a specification-driven, education-led go-to-market approach.
Rmax holds third-party validations including Intertek's Clean Air Gold certification (2023) and a 2020 GreenCE Top 5 Webinar recognition, and is positioned within Sika's broader North American construction chemicals platform. As a non-public business unit, the company does not separately disclose revenue, and its strategic direction is set within the context of its parent company's global roofing and insulation segment.
