2. Polycarbonate - Wikipedia

   en.wikipedia.org/wiki/Polycarbonate

   extrusion with cylinders into sheets (0.5–20 mm (0.020–0.787 in)) and films (below 1 mm (0.039 in)), which can be used directly or manufactured into other shapes using thermoforming or secondary fabrication techniques, such as bending, drilling, or routing. Due to its chemical properties it is not conducive to laser-cutting.

3. Twinwall plastic - Wikipedia

   en.wikipedia.org/wiki/Twinwall_plastic

   Twin-wall polycarbonate is able to flex in the demanding conditions of four-season greenhouses and allows for consistent temperature management because of the insulative properties. [ 12 ] Twinwall Polycarbonate sheeting is primarily installed with glazing bars, which secure the sheets down to the frame, whether timber, metal or other framing ...

4. Wall panel - Wikipedia

   en.wikipedia.org/wiki/Wall_panel

   While there is no set size limit for a piece of material fulfilling these functions, the maximum practical size for wall panels has been suggested to be about 0.6 to 2.4 m (2 to 8 ft), to allow for transportation. [1] Decorative wall panels are also known as charcoal wall panels, PVC wall panels, WPC wall panels, charcoal louver panels, PVC ...

5. Thermoplastic-sheathed cable - Wikipedia

   en.wikipedia.org/wiki/Thermoplastic-sheathed_cable

   4/1.5 mm 2 and 6/2.5 mm 2 have stranded conductors and a solid CPC (fixed high power equipment or sub-mains) 10/4 mm 2 and 16/6 mm 2 have stranded conductors and CPC (fixed high power equipment or sub-mains) In older properties (pre-1970) cable with imperial sizes are found, sometimes without CPC.

6. List of thermal conductivities - Wikipedia

   en.wikipedia.org/wiki/List_of_thermal_conductivities

   Also the copy is blurred up enough to give you the impression that maybe what it really means is 1.36 W −1 cm −1 K −1 and 78.6 Btu hr −1 ft −1 F −1 and a type-head that got overdue for its cleaning since the secretary had a tall heap of papers on her desk and if that is the case then the multilingual expression is perfectly ...

7. Architectural glass - Wikipedia

   en.wikipedia.org/wiki/Architectural_glass

   The evacuated space between the two sheets can be very shallow and yet be a good insulator, yielding insulative window glass with nominal thicknesses as low as 6 mm overall. The reasons for this low thickness are deceptively complex, but the potential insulation is good essentially because there can be no convection or gaseous conduction in a ...
