Hi I have fixed my policarbonate greenhouse few time and last time has hold the first 3 storms and I was happy about it but Desmond the last storm proved me wrong. The problem is the roof and this time that I had glued the sheets at the frame with clip and blob of silicone to hold the w clip in place not only the sheets blow away but even the metal piece in the middle that hold the piece together is gone (luckily I found it at the back street). So now the problem number one is that the policarbonate sheets are the cheaply one from b&q and not the twin wall. So now I bought some twin wall 4mm policarbonate sheets and I want to repair. What do you suggest? It's only a 6x4 greenhouse.

Fix some timber battens inside the greenhouse & screw the polycarb to it.sigpic“Gorillas are very intelligent, but they don't have to be as delicate as chimps -- they can just smash open the termite nest,”

Get the right silicone there are many different varieties for many different purpose's. For instance if you use sanitary silicone if will have very poor 'grab' adhesion to metal.Potty by name Potty by nature.

If you go with BMs suggestion use strapping on the outside as screw heads are too small to fix securlyit may be a struggle to reach the top, but once your over the hill your problems start.

I have a greenhouse in a windy location where lots of glass has been broken and then replaced with polycarb, to combat the wind issues I have siliconed the panels, but I have also added a tumble drier vent ( like this ) which relieves any build up of pressure in the GH when the wind blows over the top (which usually pops the panels out).
This has worked upto now in winds over 70mph.
