Buying a Greenhouse (5)

What kind of glass is used – i.e. is it shatter proof or tempered? What warranty comes with purchase?

Hartley Botanic Glasshouses are single glazed in 4mm tempered safety glass, with all edges cushioned by TPR (Thermo Plastic Rubber) glazing seals, bonded to the glass.  Each pane is held within its own individual framework on all sides, meaning NO glass to glass, glass to metal, nor overlapping glass contact. This method of glazing, unique to Hartley, completely eliminates glass slippage.  Although it is extremely difficult to break the glass, as proven through decades of successful use in many harsh climates throughout the world, it is not possible to guarantee glass.

What is the best orientation for a greenhouse? We have fully exposed southern exposure with east and west affected by the house.

If possible, place your Hartley greenhouse where it will receive at least 4 to 6 hours of direct sunlight during the winter months.  If possible, the best orientation is usually to position the greenhouse with the ridge or peak running east and west, as this will provide more heat gain from the sun during the winter.  And if you require shades for late spring, summer and early fall, you’ll most likely reduce your shade costs for odds are you’ll only need shades on the southern side of the roof.

Greenhouse Maintenance (2)

I purchased a V & N Hartley semi-dodecahedron greenhouse druid hand. To move it I carefully removed every glass from the frame. Unfortunately some were broken. Also the trim and the glass was brittle and I would not want to use it when I replace the glass in the frame once I set the frame in it's new location. Is it possible to purchase new trim? In addition I have misplaced some of the clips that secure the glass panes in the frame. Are those available for purchase? If the trim is not available could a bead of sealant be applied to the frame and then the glass placed on the sealant?

We can supply the Thermal Plastic Rubber but no longer supply the clips, please call to discuss your needs in more detail 01457 873244 (UK) 781 933 1993 (USA)

I am disassembling a Hartley 10 greenhouse to move to another site and have come across a problem at the back section. How to take the glass out. I have taken out the top layer, but can't see a way to take out the rest as there are no screws or bolts, only rivets! Your advice would be greatly appreciated!

We have a video on the UK site:  http://www.hartley-botanic.co.uk/video-gallery/instructional-videos which shows the assembly which may be helpful if your Hartley 10 is a fairly recent model. Alternatively you could email images which would help us determine how to help you to [email protected]

Heating a Greenhouse (1)

Preparing the site for a Hartley Greenhouse (3)

This is the style I am interested in https://hartley-botanic.com/product/victorian-lodge-coldframes-us/, I am going to build the greenhouse on a hillside. You know the framework of the greenhouse is metal, I am wondering how to make sure the greenhouse is lightning safe. Do I need to install a rob? Or simply have it grounded is enough? Or is the greenhouse lightning safe in nature (aka, does it work just as a Faraday cage in this case). It would be deeply appreciated if your company can share some material with me to improve its lightning safety when I am preparing the site. Thanks in advance.

Being of highly conductive Aluminium, Hartley Greenhouses would readily conduct lightning to ground if struck.  Additionally, the larger Victorian structures are anchored with steel or stainless steel rods at the main frame positions and these route either partially or fully down through the wall (as on a Victorian Lodge – 8 positions).  As we have no recorded instance of one of our structures ever being hit, we cannot give any estimate of the likely damage that would occur should this happen.  A lightning rod may reduce the likelihood of severe damage, but as we have no established product in this area, sourcing, installation and maintenance would be entirely the owners responsibility.  We cannot advise that a Hartley Glasshouse be used as a safe haven during an electrical storm, but being inside would be better than no shelter at all as long as contact with the metalwork is avoided.  For more information on safe havens please follow this link http://www.growingformarket.com/articles/lightning-safety

We are considering one of your greenhouses in a lean to configuration against the side of our existing house. The house is currently a wood/painted cedar clapboard siding. What considerations are necessary for the exterior wall of the house where the lean to attaches, for example will the heat and or moisture damage or destroy the siding or does the siding need to be replaced with a stone face of some sort.

You wouldn’t need to replace cedar with stone/brick.  Most have their builder ensure to have some type of vapor barrier on abutting wall behind the cedar siding.  The homeowner’s builder would strip the cedar siding off, and have a vapor barrier in place (and there is probably already one in place), and also install flashing to flashing lines noted on the Hartley drawings.  Then, once Hartley is erecting the glasshouse, the homeowner’s builder/GC would bend the flashing down over the greenhouse’s flashing and then re-install the cedar siding.  Finally, you may wish to power wash the common wall once a year, say in the dead of summer, which would most likely be the time your greenhouse is empty and before you get ready for your upcoming greenhouse season.
