Made with reclaimed polyisocyanurate (polyiso) insulation—which has the highest R-value per inch of any common insulation material—Green InsulWall from Randall Manufacturing is offered for use in commercial buildings as an energy-conserving, modular wall system.
The rigid, insulating modular curtain wall is easy to install and can be moved, rehung, and reused as a facility’s needs change.
The system improves insulation capacities and is constructed of salvaged commercial roofing insulation, preventing landfill waste.
