Why a monocoque motorhome? a unique shield, without equal

The bodywork of the monocoque GRP motorhome is made with a sandwich system: fiberglass sheet + polyurethane foam insulation panel + fiberglass sheet. Inside the self-supporting structure, there are no wooden parts (which can decompose) or metal parts (which would act as a thermal bridge).

Why in fiberglass?

Fibreglass is an extremely strong, elastic and lightweight material. This great elasticity eliminates the risk of hail damage and gives rigidity, protection during travel and durability to the entire living cell of the monocoque motorhome.

Unlike metal, GRP is also not a heat conductor. A body made of metal, or one that contains metal parts, cannot retain heat on the inside, it is naturally conducted towards the cooler exterior - consequently it cannot guarantee good thermal comfort on the inside. The monocoque GRP motorhome, on the other hand, consists of a sandwich structure made exclusively of GRP and polyurethane foam. Once the inside of the fiberglass monocoque is heated there is no dispersion / exchange of heat from the inside to the outside - the heat remains inside.

The thermal comfort is unmatched and the savings in terms of consumption are evident

DOOR, lockers AND DOORS IN FIBERGLASS sandwich and pu

In order to improve thermal comfort, exclude infiltration problems and improve the aesthetics of our monocoque motorhomes (avoid external frames, visible hinges and silicones), since 2009 we have introduced doors and doors made of solid, lightweight, 'flat-shape' fibreglass with no external frames, no visible hinges and no need for external silicon.

We have also replaced all the external door handles, adopted a solid Fiat lock handle for the entrance door and designed an innovative and unique central locking system in the sector.

Patented concealed hinges

With the dual objective of avoiding thermal bridges and obtaining a cleaner and more streamlined external line in addition to the “flat-shape fiberglass door and hatches, Wingamm adopts special concealed THIRD patented hinges.

A zipper solid, resistant, in Zamak alloy, which works completely hidden inside the door on one side and the body on the other.

Zamak is a non-ferrous alloy characterized by high hardness and resistance. The Third hinge is composed of a central body, levers, pins and fixing screws all made of Zamak. The slots, which allow the hinge to be fixed, are housed in the special “rotating bushings”, whose 360 ° rotation allows ample registration margins. Each hinge is housed inside a protective shell made of cast aluminum. The shells are positioned, by means of a mold, in the foreseen points of the bodywork and subsequently resinated to form a single body with the bodywork.
