R-value (insulation)

The R-value is a measure of thermal resistance used in the building and construction industry. Under uniform conditions it is the ratio of the temperature difference across an insulator and the heat flux (heat transfer per unit area per unit time, ) through it or . Thermal resistance varies with temperature but it is common practice in construction to treat it as a constant value.

An R-value is a unit of thermal resistance for a particular material or assembly of materials (such as an insulation panel). The R-value depends on a solid material's resistance to conductive heat transfer. For loose or porous material, the R-value accounts for convective and radiative heat transfer through the material. However it does not account for the radiative or convective properties of the material's surface, which may be an important factor for some applications.

R is expressed as the thickness of the material normalized to the thermal conductivity. The unit thermal conductance of a material is the reciprocal of the unit thermal resistance. This can also be called the unit surface conductance. The higher the value of R, the better the building insulation's theoretical effectiveness.

There is a small Salesian church in the neighbourhood, called "The Church of St.Anne".

In Rudeš, there is also an elementary school called "Elementary school Rudeš".

A soccer team that is currently in the second Croatian soccer league and is from Rudeš is called NK Rudeš.

Rudeness

Rudeness (also called effrontery) is a display of disrespect by not complying with the social norms or etiquette of a group or culture. These norms have been established as the essential boundaries of normally accepted behaviour. To be unable or unwilling to align one's behavior with these norms known to the general population of what is socially acceptable is to be rude and are enforced as though they were a sort of social law, with social repercussions or rewards for violators or advocates.

Rudeness "constituted by deviation from whatever counts as politic in a given social context, is inherently confrontational and disruptive to social equilibrium" (Kasper, 1990, p. 208). Rudeness, particularly with respect to speech, is necessarily confrontational at its core.

Forms of rudeness include acting inconsiderate, insensitive, deliberately offensive, impolite, a faux pas, obscenity, profanity and violating taboos such as deviancy. In some cases, an act of rudeness can go so far as to be a crime, for example, the crime of hate speech.
