Abstract
The present invention relates to a method of producing an improved hull at new building of and renovating ships and boats having metal hulls for accomplishing high finish, good heat insulation and good acoustic attenuation, according to which sheets or mats of cellular plastic are glued on to the outside of the hull with the use of a glue giving an elastic or viscoelastic glue joint.
Claims9
A method of producing an improved hull for a marine vessel, comprising:
- providing a marine vessel having an outer surface defined by a metal hull;
- applying sheets or mats of cellular plastic material to the outer surface of the metal hull, wherein glue is provided between the hull and the sheets or mats to form an elastic or viscoelastic joint, the sheets or mats imparting insulating and acoustic attenuation properties such that a temperature on an inside surface of the metal hull at 70% relative humidity is above the dew point when a temperature on an outer side of the mats or sheets is between -10.degree. C. and 40.degree. C.
