| We got this twin-wall polycarbonate shipped up from Karachi. Bizarrely, it was only available in sheets 19' x 6'11", so all of the panel sizings were designed around this. We had them slice them into 5 equal parts for easier shipping. And on the right panel at least, easier mounting too, as we've had one or two minor alignment issues since we first put the frames up. |
 |
| This is the satisfying bit, like peeling off a 7-foot plaster. The lighter blocks are to keep the glazing off the pipes, should it bend/sag once it's warmed up. Yes, we probably should have painted them black too, but that would have wasted another half-day while we waited for it to dry. |
 |
| Whether by learning from experience or from fluke, we did a better job of keeping things perfectly straight when we constructed the left panel's frames, so all the glazing just dropped neatly into place. Aah. |
 |
| All glazing in place, secured down by wooden slats and liberally silicone'd. And now ready for its first wash by the looks of it. This is a generally dusty place anyway, but possibly being near the incinerator doesn't help. |
 |
| Specially procured polyurethane insulation for the backs of the panels. The Pakistanis' favourite cheap styrofoam is no good as it has a tendency to melt at the temperatures we'll be asking of it. |
 |
| 3 down, 7 to go. We've also insulated all the hot pipe runs with fibreglass wool. |
 |
| Trying to screw stuff into place while holding it upwards onto a slope of 50° is not easy. |
