  7. 8 MM UV coated twin wall polycarbonate over main body
  8. 10 MM twin wall polycarbonate in front & back walls - for extra strength
  9. Inside walking height: 73" near shelves - 83" to 90" in the middle
  10. Assembly time: 2 people 1 full day (3 makes it easier and reduces it to 6-8 hours (excluding any
    shelves) - very few nuts & bolts
Note:
The assembly is not difficult, but just a little tricky - which is why using 3 people makes all the
difference. The RIGA was specially designed with the home owner in mind - its shape allows for
maximum inside head room, yet requires no eaves - requiring less structural material and making it
easier to assemble. The Riga is likely the strongest greenhouse in its price range. No weather has ever
destroyed any Riga greenhouse, other than tornadoes or hurricanes.

Riga IV Greenhouse
Foundation Frame Kit / Mounting system (optional base):

  • The Foundation Frame attaches to the bottom of the RIGA greenhouse profiles
    and usually sits on the ground, but it can also be mounted on top of 6” x 6”
    treated lumber, a concrete or brick wall to provide 5” of additional head space
    inside

This frame is heavy and fastened at the corners with stakes and it will be very secure
in most winds

Why is ventilation so important?
  • Because, in many parts of the U.S. temperatures can change drastically  from
    cold nights to hot afternoons. To compensate for this, the RIGA greenhouse
    comes standard with larger and more windows than similar greenhouses. For
    this reason it comes with an oversized window in the back wall. In addition, you
    can leave the top half of the front door open allowing a breeze to flow through.
What kind of ventilation is provided in a Riga Greenhouse?
  • Automatic Window Openers with each roof window
  • An oversized 30” x 42” or 30” x 49” rear-wall window
  • An oversized Dutch barn style front door - 30”x 72” or 30” x 79” high.
  • Additional windows can be added.
How does the Automatic Window Opener work in a Riga Greenhouse - does it
need electricity?
  • No electricity is needed.
  • It comes with a special cylinder (black) filled with unique paraffin oil, which
    expands, and contracts due to temperature changes. It pushes the window
    open when it gets hot inside and closes the window when it cools down.
  • Temperature range is adjustable.

Automatic Vent Opener for Riga Greenhouse
How are the roof windows attached?
FYI: with most greenhouses they hang form simple hinges, which can break if the
window is left open in heavy winds.
  • The RIGA roof windows are attached with a “tongue and grove” hinge system,
    which spans the full length of the top profile of the roof window
  • The top profile sits “inside” a grove in the roof beam.
  • It is attached by sliding the assembled roof window down the groove in the roof
    beam from either end of the roof beam.
Schematic of Riga Window Hindge
Frame: Aluminum Profiles:
The RIGA profiles are thicker/bigger diameter and with more channels than other
greenhouses in its class - this makes them stronger.

Extra strength in the unit comes from the main uprights being attached to the Base
Profiles by sliding into each other (no bolts & nuts to come loose over time)
