More about greenhouse bases

Paul, you don`t fix the base down until the `house has been glazed. You need to be able to adjust the building if it`s out of square.:gnthb:

 

Why cant you square it up before you glaze it.

 

With aluminium greenhouses, they only need to be a quarter of an inch out and you will have a problem when you get to the last few panes. So you glaze first, fix down second.:thumb:

 

Are we talking squareness or level/plumb.

Squareness can easily be checked by getting the two diagonals equal.

If the framework is also level and not winding, I cant see there can be a problem, unless the glass is cut out of square.

 

Umm.. this seems like common sense, but the instructions with my pile of bits tell me to complete the frame, then screw it to the ground, then glaze....

 

Just my thoughts but how do you move a very rickkety fully glazed greenhouse if its not sitting square.

Also there could be the chance of breaking some of the glass during the fixing process, depending on how you go about it.
