Thermal resistance of materials with the same thickness
R = Thermal Resistance of a material
Higher R = greater insulation
Thickness = 150 mm

Type of insulation material
Difference in thickness between different materials with the same thermal resistance
D = thickness
Thermal Resistance = (7.5m² x K/W)

Type of insulation material
Comfort all year round, in any condition
Wingamm campers are designed to offer uncompromising thermal and acoustic comfort, thanks to our exclusive fiberglass monocoque with polyurethane insulation. A technology that guarantees a quieter, more efficient and pleasant travel experience, in summer and winter.
Efficient campers even in winter
Thanks to polyurethane, which offers maximum thermal resistance (R value) with minimum thickness, the heat stays inside during the winter and outside during the summer. The internal temperature of the camper remains constant and uniform, improving comfort and energy autonomy.
Higher R = better insulation
Reduced thickness = lower weight = lower consumption
These advantages also impact handling and efficiency on the road: less weight, lower fuel consumption.
Campers with superior thermal insulation: the secret is polyurethane
Our construction system is based on a monocoque sandwich composed of:
-
two layers in fiberglass (internal and external)
-
a central layer in high density rigid polyurethane foam
This technical solution guarantees:
-
Superior thermal insulation of 70% compared to extruded polystyrene, the material used by most traditional campers
-
Elimination of thermal bridges, thanks to the absence of metal and wood in the body
-
Energy saving up to 30% in gas consumption for heating
A silent camper: integrated sound insulation
In addition to the heat, the noise also stays outside.
The Wingamm monoblock structure, without mechanical joints and completely glued, eliminates vibrations and creaks. The furniture is also fixed directly to the body, avoiding unwanted noises while driving.
The result? A feeling of calm and welcome that transforms every trip into a relaxing experience.
