SECURING GREENHOUSE TO BASE
BRICK BASE, TIMBER OR CONCRETE
Having built your base level and square and to the outside measurements, sit the greenhouse onto the brick base. The 4
cills will lip over the edge of the base and will protrude approx. 7mm all the way round.
Drill through the cill and into the timber/brickwork; screw through the hole using a treated screw and washer. Create an
anchor point every 610mm i.e. at ach glazing bar.

PATIO FLOOR
You must make sure that the structure is level and square. Put one pane of Polycarb in each corner of the roof, each
pane must be level with the small Polycarb retaining lip just above the gutter and be running parallel with the roof glazing
bars. Each corner must be the same. If one corner is out the corner diagonally opposite will also be out. By carefully
pushing and pulling each corner diagonally you will be able to see the frame move in and out of square with the Polycarb.
Having established the square of the greenhouse, drill the patio or concrete in the required positions, fit plastic plugs and
screw the brackets firmly to the ground using 35mm x 8mm round head screws.
SOIL FLOOR
Determine the square of the greenhouse as described above, make a mix of concrete and put a couple of shovelfuls
around the base of each stake. When the concrete has gone off back fill with the soil excavated earlier on.
BRICK BASE
When anchoring the frame to a brick base you need to drill through the cill and into the brick. Insert a timber or plastic
plug into the hole in the brick and screw the cill down using a treated screw. Position the hole in the cill as near to the
angle corner as possible so that when you glaze, the screw is on the inside of the Polycarb.

FITTING THE DOOR TO THE STRUCTURE
The door slides onto the frame from the left hand side.
Put the door bottom rail into the bottom door track and slide to the right, feed the first wheel into the upper door track
and move further to the right until the black draught excluder butts up to the end glazing bars. Carefully ease the door
past the glazing bar and feed in the second wheel. Push further to the right until both draught excluders are butting up to
both end-glazing bars. Carefully ease the door past the two glazing bars. The door will now run quite freely. To square
up the door with the spacing, undo the upper bolts holding the door track. There is a little play to facilitate “fine tuning”
of the door. N.B. Sometimes the door can be a little stiff prior to glazing but once the Polycarb has been inserted (the
last job of the construction) the extra weight will make for smooth running. (Key point).
Angle Brackets
The aluminium angle brackets are bolted to the cill and then with the use of screws are secured to the base.
Timber screws are available on request.
