2. Twinwall plastic - Wikipedia

   en.wikipedia.org/wiki/Twinwall_plastic

   Twin-wall plastic, specifically twin-wall polycarbonate, is an extruded multi-wall polymer product created for applications where its strength, thermally insulative properties, and moderate cost are ideal. [1] Polycarbonate, which is most commonly formed through the reaction of Bisphenol A and Carbonyl Chloride, is an extremely versatile ...

3. Polycarbonate - Wikipedia

   en.wikipedia.org/wiki/Polycarbonate

   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.

4. Trombe wall - Wikipedia

   en.wikipedia.org/wiki/Trombe_wall

   Today, the Trombe wall continues to serve as an effective strategy of passive solar design. The first well-known example of a Trombe wall system was used in the Trombe house of Odeillo, France in 1967. [13] [3] The black painted wall is constructed of approximately 2 foot thick concrete with an air space and a double glazing on its exterior ...

5. Sandwich panel - Wikipedia

   en.wikipedia.org/wiki/Sandwich_panel

   Sandwich panels are an example of a sandwich-structured composite: the strength and lightness of this technology makes it popular and widespread. Its versatility means that the panels have many applications and come in many forms: the core and skin materials can vary widely and the core may be a honeycomb or a solid filling.

6. Structural insulated panel - Wikipedia

   en.wikipedia.org/wiki/Structural_insulated_panel

   The panels can be used as floor, wall, and roof, with the use of the panels as floors being of particular benefit when used above an uninsulated space below. As a result, the total life-cycle cost of a SIP-constructed building will, in general, be lower than for a conventional framed one—by as much as 40%.

7. Girder and Panel building sets - Wikipedia

   en.wikipedia.org/wiki/Girder_and_Panel_building_sets

   The Girder and Panel Building Set construction kits enabled a child to build plastic models of mid-twentieth century style buildings. Vertical plastic columns were placed in the holes of a Masonite base board and horizontal girders were then locked into the vertical columns to create the skeletal structure of a model building.
