Title: Matthew T Langdon: Innovator in Acoustical Panel Technology
Introduction
Matthew T Langdon is a notable inventor based in Cloquet, MN (US). He has made significant contributions to the field of acoustical panel technology, holding 2 patents that showcase his innovative approach to sound absorption and material composition.
Latest Patents
One of Langdon's latest patents is for a mineral fiber-based ceiling tile. This acoustical tile features a wet laid mineral fiber basemat, a non-woven porous fiberglass veil adhered to the basemat, and is covered with a light reflecting air permeable coating. The design ensures that at least 90% of the weight of the basemat comprises mineral wool and binder, with the binder's weight being less than 1/11 of the weight of the mineral fiber. The basemat has a density ranging from about 11.4 to about 14.2 lbs/cubic foot, and the mineral fiber has an average diameter between 4.5 and 8.3 microns. This composite exhibits excellent NRC and CAC performance values.
Another significant patent involves a method of making a coating and a coated acoustical panel using degraded fibers. In this process, a thin, acoustically-transparent coating is applied to an acoustical base mat. A pulp is created from various fillers, a fibrous filler, a binder, and water. A thickener solution is prepared and mixed with the pulp under high shear conditions to degrade the fibrous filler, resulting in a smooth coating. This coating is then applied to the base mat, which is cut and dried to form a coated acoustical panel that is free of visible mineral nodules on the surface.
Career Highlights
Langdon has worked with prominent companies in the industry, including USG Interiors, Inc. and United States Gypsum Company. His experience in these organizations has contributed to his expertise in acoustical materials and innovative product development.
