Build Better RVs with Smarter Composite Materials
From caravans and campervans to motorhomes and more, Liner’s sandwich panel components for recreational vehicles (RVs) deliver strength, insulation, and durability in lightweight form. Our GRP and CRFTP facings, high-performance core materials, and advanced adhesives are engineered for structural integrity while keeping weight and petrol consumption low.
These materials help improve thermal performance, reduce water absorption, and withstand road stress, vibration, and weather extremes. This makes them ideal for RV walls, roofs, floors, and cabinetry. Each component is selected to meet the practical demands of travel and long-term outdoor use.
Why Composite Panels are Ideal for Recreational Vehicles
These offer:
Lightweight Structure Enables more efficient travel and easier handling | Thermal Insulation Keeps interiors cooler in summer and warmer in winter | Customisable Design Allows for tailored panel build ups, thicknesses, and finishes, and layouts |
Water and Moisture Resistance Prevents damage from rain, humidity, or coastal environments | Sleek Aesthetic Finishes Allows for smooth, modern interiors |
