Abstract
A system of temperature determination and control for molten bituminous material during construction of built-up roofs is provided wherein a heating temperature is preselected based upon a number of factors and is adjusted insofar as may be called for upon checking the temperature upon application to the roof deck. Factors considered in the predetermination include type of bituminous material, type of roofing material, and deck type and temperature; ambient temperature, cloud cover, and wind speed; and also opportunities for cooling of the bituminous material between temperature-controlled and deck locations, during application to the deck, and thereafter until application of an overlying layer of roofing material.
Claims9
In formation of built-up roofs using molten bituminous material to adhere layers of roofing material, the improvement comprising heating bituminous material to melt it, sensing the temperature of the bituminous material being heated, sensing the temperature of molten bituminous material on the roof deck, and adjusting the heating temperature so that the temperature of the molten bituminous material applied to the deck will be within a predetermined satisfactory adhesion temperature range.
In formation of built-up roofs, requiring determination of heating temperature in melting of bituminous material for adhering adjacent layers of roofing material, the improvement comprising selecting the composition of roofing material to be used, sensing ambient conditions including roof deck temperature conducive to temperature change of the molten bituminous material, and basing the heating temperature in predetermined manner upon such material composition and upon such ambient conditions conducive to such temperature change .
In formation of built-up roofs, for which bituminous material is heated to a controlled temperature preparatory to application thereof to a roof deck, the improvement comprising sensing the temperature of the roof deck and taking the sensed temperature into account in controlling the heating temperature of the bituminous material to optimize on-deck adhesion.
In formation of built-up roofs, for which bituminous material is heated to a controlled temperature preparatory to application thereof to a roof deck, the improvement comprising sensing the temperature of the roof deck and the ambient air temperature and taking the sensed temperatures into account in controlling the heating temperatures of bituminous material to optimize on-deck adhesion.
