2. Twinwall plastic - Wikipedia

   en.wikipedia.org/wiki/Twinwall_plastic

   Although single layer polycarbonate sheeting is more flexible than polycarbonate in twinwall configuration, it still retains significant advantages over alternative materials, including glass. A typical 6mm sheet has a density of 0.72 g/cm^2 [ 6 ] and a thermal insulation R value of 0.3 m^2°C/W, while allowing 80% of visible light pass through ...

3. Quadruple glazing - Wikipedia

   en.wikipedia.org/wiki/Quadruple_glazing

   They represent a vast improvement over single-pane windows but the potential for even greater energy savings with more highly insulating windows has been elusive. Recent price reductions in the thin glass used in both smartphones and flat-screen TVs, as well as in the krypton gas used in halogen lights, however, have made it possible to build ...

4. Insulated glazing - Wikipedia

   en.wikipedia.org/wiki/Insulated_glazing

   A typical installation of insulated glass windows with uPVC frames. Possibly the earliest use of double glazing was in Siberia, where it was observed by Henry Seebohm in 1877 as an established necessity in the Yeniseysk area where the bitterly cold winter temperatures regularly fall below -50 °C, indicating how the concept may have started: [2]

5. Polycarbonate - Wikipedia

   en.wikipedia.org/wiki/Polycarbonate

   Polycarbonate has a glass transition temperature of about 147 °C (297 °F), [8] so it softens gradually above this point and flows above about 155 °C (311 °F). [9] Tools must be held at high temperatures, generally above 80 °C (176 °F) to make strain-free and stress-free products.

6. Vacuum insulated panel - Wikipedia

   en.wikipedia.org/wiki/Vacuum_insulated_panel

   A vacuum insulated panel (VIP) is a form of thermal insulation consisting of a gas-tight enclosure surrounding a rigid core, from which the air has been evacuated. It is used in building construction , refrigeration units, and insulated shipping containers to provide better insulation performance than conventional insulation materials.

7. Structural insulated panel - Wikipedia

   en.wikipedia.org/wiki/Structural_insulated_panel

   Typical U.S. height for panels is 8 or 9 feet (2.4 or 2.7 m). Panels come in widths ranging from 4 to 12 inches (100–300 mm) thick and a rough cost is $4–$6/ft 2 in the U.S. [5] In 4Q 2010, new methods of forming radius, sine curve, arches and tubular SIPs were commercialized. Due to the custom nature and technical difficulty of forming and ...
