Latest Patents
Deirdre holds a patent for a "Transparent acoustical and mechanical barrier." This invention features an optically transparent glazing that measures about 3 to 5 mm in total thickness. The glazing includes an interlayer film composed of at least two polymeric film layers. The core film layer has a modulus of at least 25,000 psi (173 MPa), while the surface film layer has a maximum modulus of 15,000 psi (104 MPa) at frequencies ranging from 50 to 10,000 Hz and at a temperature of 20°C. The glazing is characterized by an acoustical barrier insulating capacity that is at least equivalent to that of a 3.85 mm thick monolithic pane of glass. Additionally, it has an Articulation Index value of less than 64.2% and a sharpness value of less than 150 at the same frequency range. The interlayer film has a bending stiffness of at least 0.01 Pa*m, and the surface film layer has a maximum tan delta of 0.6 at the specified conditions.
