Patent number: 9200450Abstract: A ridge cap includes a lower surface adapted to be placed in contact with a roof of a building, a weather protective upper surface, and first and second side sections connected to each other. The first side section is disposed at one side of a longitudinal axis and the second side section is disposed at the other side of the longitudinal axis. The ridge cap further includes an elastomeric strip and a metal strip. The elastomeric strip extends along the longitudinal axis and connects the first side section and the second side section to be of unitary construction with the first and second side sections. The metal strip backing extends along the longitudinal axis and supports the elastomeric strip.Type: GrantFiled: October 7, 2013Date of Patent: December 1, 2015Assignee: DEVPAT, LLCInventors: George F. Thagard, III, Casey G. Tzeng

Publication number: 20140318034Abstract: A method of making a rounded ridge cap includes providing an intermediate product comprising a plurality of sections arranged side by side and integrated as a single body of an asphaltic foam material, each of the plurality of sections comprising a rounded top surface, the plurality of sections comprising first and second sections immediately neighboring each other. The first section comprises a first side and the second section comprises a second side integrated with the first side to form a bridge portion between the first and second sections. The method further includes bending the first section with respect to the second section about the bridge portion, thereby forming a rounded ridge cap comprising a rounded exterior surface. The rounded top surfaces of the first and second sections form together the rounded exterior surface of the rounded ridge cap.Type: ApplicationFiled: October 25, 2013Publication date: October 30, 2014Applicant: DEVPAT, LLCInventors: George F. Thagard, III, Casey G. Tzeng

Patent number: 5965626Abstract: An asphaltic isocyanurate foam useful in roofing applications. The foam is made from asphalt having a penetration range of between approximately 5-25, a softening point of between approximately 120.degree. F. and 200.degree. F., and an asphaltene content of no more than about 30%. This asphalt is liquified and mixed with a mixture of polyols such as Voranol 270, Multranol 9138, and castor oil. Other chemicals, such as a surfactant, a viscosity reducer, and a flame retardant can also be included in this mixture. The mixture is then brought to a temperature of between approximately 140.degree. F. and 220.degree. F., mixed with water and a polyisocyanate in a molar ratio of polyisocyanate:polyol of between about 2.0:1 and about 2.5:1 and reacted to form an asphaltic isocyanurate foam.Type: GrantFiled: March 10, 1997Date of Patent: October 12, 1999Assignee: Fontana Paper Mills, Inc.Inventors: Casey G. Tzeng, George F. Thagard, III

Patent number: 5813176Abstract: A ridge cap has an upper surface and a lower surface which is adapted to be placed in contact with a roof of a building. The ridge cap also includes a longitudinal axis having a front end and a back end, as well as two sides located axially distal of the longitudinal axis. A central channel along the longitudinal axis is located in the lower surface. A protuding member extends from a surface of the central channel. Another surface of the central channel includes a notch adapted to receive the protuding member. The protuding member and the notch are adapted to cooperate so as to at least substantially block the central channel when the ridge cap is bent and a distal end of the protruding member is made to enter into the notch.Type: GrantFiled: June 7, 1995Date of Patent: September 29, 1998Assignee: Fontana Paper Mills, Inc.Inventors: Casey G.
