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 to be used in conjunction with the main instruction manual (read them before this 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 framework. This does not include glazing, mov-
ing 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.
