or rolled up (looses stickiness) or in one piece (might be too wide). Whichever way you do this make sure you do not tape up the gulley at the edge of the window frame for the spring clips to go in place and secure the glass.Clean everything – gutters and glass particularly – before you get it to the new position and make sure that all the screw holes and all the drain holes are open.
Assembly
Before you try to assemble your new (well, old) greenhouse you need to make some preparations. Buy new spring clips and throw the old ones away, they become corroded and lose their strength. You need four clips for each pane of glass.
You also need to make a base. If you create a concrete base a couple of inches thick, which has anchor points – spaces so you can hammer the anchoring hoops into the soil, you will have the best base there is. You need to make sure the anchoring hoops are well seated, and are uncorroded. You can buy new ones from builders’ merchants and DIY stores.
Assemble the base first and use a piece of square wood to make sure the corners are 90 degrees. Now anchor the base before constructing the rest of the greenhouse. Every joint should be square before tightening up all the nuts.
Make sure the base is securely anchored in position with long anchoring pins
You will need help in getting the walls together – do not let them fall but rope everyone in to hold it up until you have it all bolted together.
A well prepared base will pay dividends over the years
Once the roof is in place you can fix the gutters – if they are separate, and then glaze. Do the lower parts of the roof first, working from the inside if possible (that way you cannot fall onto the glass!)
The top roof-glasses rest on the lower ones with ‘S’ shaped fixings. Then glaze the sides and doors.
The roof light – or window – simply hinges on the frame and locks in position.
Check the gutters and how the glass panes sit in their spaces
