Thank you for purchasing your new Robinsons greenhouse. We recommend you familiarise yourself with the instructions and read all safety
information before you commence assembly. This instruction manual is also available online at www.robinsonsgreenhouses.co.uk
in our technical help section should you need to reprint it. Should you require any additional advice you can always call us on 01782 385409.
These instructions are divided into sections highlighted by a white number/letter on a black background at the bottom corner of most pages (see opposite
page for details); part lists, B-base, P-preparation, 1-side, 2-front gable, 3-rear, 4-joining the three sides together, 5-roof, 6-wall attachment, 7-vent, 8-

touches, Door/s on side of structure rather than or in addition to the gable/s. If you need to contact us for assistance please refer to the relevant section/
s. If your building is longer than 12’, i.e. has an extension then please also refer the separate extension manual.
Safety Warning
 Glass and aluminium can potentially cause injury. Please ensure you wear protective goggles, gloves, headgear and suitable footwear when
assembling and glazing the building.
 Please remember that glass is fragile and should be handled with extreme care. Always clear up and dispose of any breakages immediately.
 Do not assemble the greenhouse in high winds.
 For safety reasons and ease of assembly, we recommend that this greenhouse is assembled by a minimum of two people.
 Please clear all lying snow from the greenhouse roof as it can cause the roof to buckle or collapse.
Site Preparation
 When selecting a site for your greenhouse, it is vital that you choose as flat and level an area as possible.
 A concrete or slabbed base will provide the most solid foundation for your greenhouse.
 IMPORTANT: Do not fix your building down until the building is fully assembled, including glazing.
 Avoid placing your greenhouse under trees or in other vulnerable locations.
 To minimise the risk of wind damage, try to select as sheltered a site as possible, e.g. beside a hedgerow or garden fence.
Additional Considerations
 Please bear in mind that assembling your greenhouse can be time consuming. You may need to spread the construction over two or more
days. We recommend that you avoid leaving the building partially glazed. If you ever have to leave your greenhouse half assembled and not
anchored down, weigh it down with slabs or bags of sand to stop the wind moving it.
 You will find it helpful to prepare a large, clean and clear area in which to work in. A garage floor or flat lawn area is ideal.
 If you have arranged for someone to install your greenhouse for you, please check that all components are included. The components can be
identified by their distinctive profiles, lengths and quantities detailed in the parts list (see next page).
 Anchoring down your greenhouse should be the final stage of construction (including glazing).
 Once installed your greenhouse requires little maintenance, but to maintain the smooth running of
your door(s) WD40 or similar can be applied to the door wheels and lower door guides.
Guarantee
 Your new Robinsons greenhouse is guaranteed for 10 years against faulty manufacture of the frame-
work. This does not include glazing, moving parts, accidental damage or wind damage.

UPDATE: Robinsons plastic / aluminium cover strips -
On a Robinsons building the glazing capping is in two parts. The lower plastic
capping screws into the glazing bars pressing the glass down onto its rubber
beading. The upper plastic / aluminium covers then need to be applied to cover
the heads of the self-tapping screws. If you are struggling to press on the cover
strips then we recommend the use of a rubber mallet or perhaps a wooden block
and hammer, a short sharp tap onto the cover at one end is all that is needed to
stretch the cover around the lower capping protrusions locking it into place. You
can then either continue to use the mallet along the length of the cover or con-
tinue just using the palm of your hand. Once in the building and the edges are
protected Robinsons 4mm thick toughened safety glass is very strong and can
cope with the vibrations caused by hitting the covers though we would not rec-
ommend that you hit the glass directly. Some of the aluminium cover caps have a
hole in them at one end which is sometimes used to hang the parts for powder
coating. You can if you wish use the hole to stop the covers from sliding in the
roof using a glazing screw, note you will have to use a countersunk screw under
the vents to avoid interference with the vent bottom.

SECTION
No TITLE ASSEMBLY SYNOPSIS: IMPORTANT INFORMATION / CONSIDERATIONS
PARTS LIST Identify and separate all like for like components prior to assembly. The ‘parts list’ also separates parts
into the various sections 1 - 12 shown below. Parts can also be identified by their profile pictures and
stated lengths etc..
B
BASE Base dimensions and recommendations. Ensure that your base is level as this will make assembly of
the building, especially the glazing of the roof much more straight forward.
P PREPARATION Tools required. IMPORTANT: Use WD40 or similar in the glazing bar channels and insert the black glaz-
ing rubber prior to frame assembly.
1
SIDE Take the side glazing bars ‘D609’ with the rubber inserted and the diagonal braces ‘D604’, use 10mm
bolts to join them to the gutter and 15mm bolts to the cills (note how the head of the bolt slides into each
glazing bar during construction).
2 FRONT Again ensuring that the gable framework is rubbered-up follow the diagrams to assemble each end of
the building. Make sure that you have inserted the extra bolts utilised in sections 4, 5 and 11. On the
roof and side corner bars not every rubber channel will require rubber unless it is to be utilised in a parti-
tion (see separate manual and section P).
3 REAR
4 JOINING THE
THREE SIDES Take the side (1) and both gables (2 & 3) and join them together on your base. It is a good idea to tie
some ladders to the side to support them if you do not have anyone to hold them for you.
5 ROOF Attach the ridge and then the rubbered-up roof bars ensuring that they are fully butted up to the ridge
and down onto the gutter. In order to make fitting the roof purling (D593-596) easier slide one 10mm bolt
into each roof bar, they are less fiddly than using the twist in crop heads. Some tubular braces are sup-
plied to add extra strength, they can be fitted now or later with crop head bolts.
7a VENT Once the vent is glazed add silicone to the vent sides and top. Stand the vent/s on their hinge (vent top)
and then leave the silicone to set.
7b VENT SLAM The slam bar ‘D079’ can be moved up and down between the roof glazing bars so that it can be butted
down onto the pane of glass beneath, the autovent will be attached to it later on (10).
8 DOOR/S Construct the door using the diagrams and then leave to one side ready for attachment in section (11).
9
GLAZING
Layout the bar cappings and covers around the building like a sundial checking that all is present and
correct. You can also place the roof cappings in the gutters so they are closer to hand. You will notice
that your roof cappings (D924 / D929) are in one long section however you can cut this into two sections
if you wish due to the glass overlap in the roof. This will remove the bulge in the roof capping, however
keep the roof cover strips (D928) full lengths for the neatest finish.
The glass in the ends has to bevel on the black separator strip, this bevelling action allows the glass to
tuck underneath the roof corner canopy. Use the capping and the self tapping screws to then hold the
glass in place. The covers then enclose the screw heads giving a neat finish.
10 VENT
ATTACHMENT Take the assembled vent and slide the vent hinge ‘D866’ into the end of the ridge allowing the vent to
pivot open and closed. Vent stops go either side of the vent to stop any lateral movement (so insert
stop / vent / stop). Attachment of the Bayliss XL autovents.
11 DOOR
ATTACHMENT Use the bolts inserted in section (2) to attach the upper door track. The lower door runner ’D861’ and
ramp threshold ‘D088’ push down and lock together.
12 ANCHORING
DOWN Now that the greenhouse is finished and the door and vent/s are operating without interference then you
need to anchor the building down using 2” rawl plugs and screws. Use a 7mm masonry bit in a hammer
drill to create the holes.
13 OPTIONAL
LOUVRE They attach to the building during the glazing process (9) like a piece of glass with a black separator
above and below them.
14
OPTIONAL
SHELVING
15
OPTIONAL
STAGING
16 FINISHING
TOUCHES Now that the main body of the structure is complete you can add; downpipe fittings, eave bungs.
Robinsons integral cantilever staging and shelving attaches to the inside of the greenhouse frame using
either square head bolts (insert four into each side glazing bar ’D609’ during construction of the sides
(1)) or rectangular ‘crop head’ bolts which can be fitted retrospectively (both sets of bolts accompany the
shelving/staging). This system allows the height of either the staging or the shelf to be set at an operator
specific height. Commonly the staging brackets are set 900mm from the cills though you can alter this to
suit the end user/s. The aluminium shelf / staging slats come in two lengths; (4’):1240mm ‘D2002’ and
(6’):1860mm ’D2003’. These slats can combine to create any length of staging required, i.e. 4’+6’ = 10’
etc...
6 REAR WALL
ATTACHMENT The main body of the frame is complete it can be attached to the wall. Make sure that the wall bars are
vertical and the ridge is horizontal then drill and screw the building to the wall. Do not attach the base to
the ground until section (12) as your building may not be square.

Feed glazing rubber into each glazing bar and
trim to length. Notice that some channels are
only used on a partition. Applying a lubricant to
the aluminium channels will speed up insertion.
The frame is assembled by feeding square
headed bolts, either 10mm or 15mm in length
into the slots on glazing bars and then locating
those bolts through holes in purlings and cills,
etc… Twist in (rectangular) crop headed bolts
are also used towards the end of construction
to attach components to the frame when the
glazing bar slots are no longer exposed at the
ends. 10mm

There are various methods for attaching your greenhouse frame to its wall.
1) Drill through the vertical wall bars with a 7mm drill/hammer drill using a 7mm masonry bit, Use 3”
screws to secure the wall bars.
2) Drill through the vertical wall bars with a 7mm drill bit and enlarge the inner hole to 10mm. Use 2“
screws to secure the wall bars hiding the screw heads inside the bars to give a neat finish.
3) Use L-shaped brackets and 2” screws to secure the frame to the wall similar to anchoring the green-
house down (e.g. section 12).
