The IRP structure
IRP… Challenger’s most important manufacturing secret lies behind these initials.
Whether the version is VIP or Premium, our unit structures are all made following the same high standard of quality. IRP guarantees excellence in manufacturing for optimal isolation, even greater resistance and reinforced protection.
foolproof
For better resistance, a reinforced structure
Protective polyester skin
Provides greater resistance to scratches, minor impacts, gravel, hydrocarbons, ultraviolet radiation and bad weather in general.
Extra-thick floor and roof,
among the best on the market, offering greater resistance to loads and limiting deformation over time.
Sturdy wood/composite combination,
reinforces the structure of our walls and floors by combining composite longevity with the exceptional sturdiness of solid wood.
A water-tight shield,
all materials in contact with the exterior are rot-resistant and insensitive to humidity. On the inside, we prefer high-quality wood.
N.B.: Because of its particular shape, the roof of our overcabs uses a specific technology.
