Polycarbonate is commonly used in eye protection, as well as in other projectile-resistant viewing and lighting applications that would normally indicate the use of glass, but require much higher impact-resistance. Polycarbonate lenses also protect the eye from UV light.
LosslessCut is a free, platform independent video editing software, which supports numerous audio, video and container formats. [4] [5] It is a graphical user interface, with MacOS, [6] Windows [7] and Linux [8] support, using the FFmpeg multimedia framework. The software focuses on the lossless editing of the video files.

A fixed skylight consists of a structural perimeter frame supporting glazing infill (the light-transmitting portion, which is made primarily of glass or plastic). A fixed skylight is non-operable, meaning there is no ventilation. Operable skylight. An operable (venting) unit skylight uses a hinged sash attached to and supported by the frame.
Laser cut acrylic panels have been used to redirect sunlight into a light pipe or tubular skylight and, from there, to spread it into a room. [33] Their developers Veronica Garcia Hansen, Ken Yeang, and Ian Edmonds were awarded the Far East Economic Review Innovation Award in bronze for this technology in 2003. [34] [35]
Skylights on east-facing roofs provide maximum direct light and solar heat gain in the summer morning. West-facing skylights provide afternoon sunlight and heat gain during the hottest part of the day. Some skylights have expensive glazing that partially reduces summer solar heat gain, while still allowing some visible light transmission.
In earlier days, birch bark was occasionally used as a flashing material. [7] Most flashing materials today are metal, plastic, rubber, or impregnated paper. [8]Metal flashing materials include lead, aluminium, copper, [1] stainless steel, zinc alloy, other architectural metals or a metal with a coating such as galvanized steel, lead-coated copper, anodized aluminium, terne-coated copper ...
Diagram of a laser cutter Laser cutting process on a sheet of steel CAD (top) and stainless steel laser-cut part (bottom) Laser cutting is a technology that uses a laser to vaporize materials, resulting in a cut edge. While typically used for industrial manufacturing applications, it is now used by schools, small businesses, architecture, and ...
Many plastic sheds are modular to allow for easy extensions, peg-boards, shelving, attic-storage, windows, skylights, and other accessories to be added later if these additions are purchased from the manufacturer. Plastic sheds are not susceptible to termite or wood-boring insect damage, and they require little maintenance. Being rot-proof they ...
