Ultra-Thin XPS Insulation Board
Custom thin-profile closed-cell XPS foam board for walls, floors, underfloor heating and space-limited insulation assemblies
Product Overview
Ultra-Thin XPS Insulation Board is a rigid closed-cell extruded polystyrene foam board designed for construction assemblies where installation depth is limited. The uniform cellular structure provides dependable thermal insulation, low water absorption and dimensional stability while keeping the board easy to cut and install. Thin thicknesses, board dimensions, density, surface treatment and edge profiles can be customized for project and wholesale requirements.
Key Features
- Thin-profile construction for space-limited insulation assemblies.
- Closed-cell structure with stable thermal performance.
- Low water absorption for moisture-prone applications.
- Compressive grades available for different load requirements.
- B1 and B2 fire-performance options available.
- Custom thickness, dimensions, surface and edge profiles.
