摘要： What is disclosed is a conversion muntin for use on a glazing muntin to adapt the latter to support light-transmitting plastic panels, including a muntin cover element and a clamping strip. The cover element has a T-shaped configuration including a recessed stem portion and a pair of oppositely extending bearing arms. The stem is recessed to receive a portion of the glazing muntin and has a plurality of longitudinally-extending grooves formed therein. The clamping strip comprises a pair of elongated parallely-extending rails and a hood integrally formed therewith and adapted to receive the stem of the conversion muntin. The rails have oppositely-facing slightly-spaced lips which receive the conversion muntin stem therebetween and which engage said grooves to hold light-transmitting panels against the bearing arms of the conversion muntin.

摘要： A shaped acrylic glass body is provided which has a reshaped inner zone outside the plane of the border or edge region and which is characterized by excellent resistance to weather and to chemical corrosion. The shaped body is manufactured from an extruded plate of a polymer or copolymer containing at least 80% by weight of polymethylmethacrylate or a copolymer of methyl methacrylate. The extruded plate is subjected to biaxial stretching, by at least about 25% in each direction and, while the edges or border regions are gripped to maintain their dimensions, a force is applied to the interior portion of the plate while it is in a thermoelastic state to move the interior portion out of the plane of the surrounding edges.
