• Heavy-duty frame construction that can withstand high wind and snow loads
• Uses 70 lbs more aluminum than the average imported greenhouse, which makes it sturdier
• Frame material: Extruded aluminum (US grade, stronger, thicker)
• High-impact, UV-stable Polycarbonate glazing
• Glazing material: 8 mm twin-wall Polycarbonate on roof and walls
• Faster and easier assembly: Patent-pending Twist & Lock construction, as well as rigid “ribbed” design for interlocking the pieces
• 3x roof vents (2ft x 2 ft) with automatic openers for great air circulation without the need of electricity
• Expandable: Yes, in 4-foot sections
• Two large double doors (4 ft x 6 ft) for easy access with garden equipment from both gable sides
• Door is hinged and lockable
• Foundation frame: Integrated flush base design for direct anchoring to the ground or deck
• Integrated dual gutter system for easy rainwater collection
• Stem wall: Not supported by manufacturer

Is the frame anodized?

Yes & No. The aluminum frame is anodized. However, the black frame is electrostatically painted.

Is the black paint powdercoated?

No, the black paint is electrostatically applied which is stronger than powder coating. It is very difficult to scratch and should not fade dramatically. Riverstone Industries guarantees it for 10 years.

Is the aluminum frame cooler than the black frame?

Yes, the aluminum frame is on average about 7 degrees cooler than the black.

Can the MONT be attached to a concrete pad? If so what are the dimensions needed for the concrete pad?

Yes, you can use a concrete pad. Riverstone Industries recommends that you add 3 – 4 inchs to the pad on all sides. For Example: The 8ft x 8ft (exact size of 8.1ft x 8.1ft) would need a concrete pad of 8.4ft x 8.4ft. Note: Riverstone Industries does not provide concrete screws, you will need to buy these from your local hardware store.

What tools do I need for the assembly or is everything included?

Not everything is included. Here is a list of tools you will need and items included:

• Work gloves
• Safety goggles
• Spirit level
• Tape measure
• Step ladder
• Clear silicone caulk tube
• 23 1/8 inch spacer (included)
• 7/16 wrench (included)
• Philips screwdriver (included)
• Flat screwdriver (included)
• 5-foot bungee cord (included)

Can I extend the MONT Greenhouse later?

Yes, it is expandable in 4ft increments.

We live in a seismically active area south of San Francisco. I’d like to install the greenhouse on a hill. Is this the best greenhouse for my conditions?

MONTs are very sturdy greenhouses. However, the greenhouses are not tested for earthquakes. What we can suggest for you to do is to check the bolts and make sure everything is tightened after an earthquake or from time to time. The panels won’t pop out unless the frame is loose. The channels are made to fit the Polycarbonate snugly.

What does the ventilation fan do versus the auto openers in the roof?

Automatic vent openers are self-contained units which require no electricity. It is a temperature-sensitive device that automatically opens and closes a roof vent. So, they release heat and they basically require wind to make the air flow through the greenhouse. The powered ventilation fan gives you more control. It removes excess heat by creating air movement throughout the greenhouse. However, it’s just a fan, not an AC unit. So, on very hot days, you’ll still experience higher temperatures inside your greenhouse.

Do the doors swing out or slide to the side? What is the door width?

It’s a hinged door so it swings. The door opening is 4ft x 6ft.

Where does it ship from?

Georgia, USA
