Not all greenhouses are built the same and the MONT 8 ft. x 12 ft. Black Greenhouse proves this to be true. Applying good old American ingenuity to make the best product for our customers and help to elevate the industry standards of all greenhouses. Constructed from the highest quality extruded aluminum (US grade, not the thinner and more brittle foreign aluminum) and electrostatically painted black (guaranteed to contain 0.0% lead), our garden greenhouse uses on average more than 55 lb. more aluminum than the average imported greenhouse. Constructed from the highest quality extruded aluminum (US grade - not the thinner & more brittle foreign aluminum) and electrostatically painted Black (guaranteed to contain 0.0% lead), our greenhouse uses on average more than 55 lbs. more aluminum than the average imported greenhouse. Why is this important? The weaker the framework the less snow the greenhouse can hold in the winter time before collapsing on itself also the easier it will be get damages in wind. While most hobby greenhouses on the market us less expensive thinner walls and roofing materials (the crystal clear walls are as thin as .2mm), the MONT uses professional grade 8mm twin wall polycarbonate. This is the same thickness as used in the commercial greenhouses. The twin wall polycarbonate acts as a double pain window keeping cooler air in during warm months and insulating the greenhouse from cold air in the wintertime. This not only makes the MONT more efficient to grow in for a longer period of time than other greenhouses but it also adds to the efficiency of growing, cutting down electric bills for those who choose to grow year round. At 7ft 6in tall at the peak the MONT's above average interior height design also helps with displacing heat within the greenhouse while also allowing for the tallest gardeners not to have to bend down when inside the greenhouse. From the integrated base to the built in rain water gutter system, to the automatic roof vent opener and the newly redesigned hinged double doors with an opening of almost 6ft high x 4 & 1/2ft wide ensures you are sure to enjoy the MONT greenhouse for years to come. The MONT also offers the ability to grow as your needs grow with the 4ft extension kit that can be purchased anytime in the future. You get what you pay for and with the MONT this rings true. We back the MONT with the strongest warranty in the industry (10 yrs.) on the frame and Polycarbonate. For the gardener that is looking for a mid-priced greenhouse system that will supply years of hassle free indoor gardening this is the greenhouse for you. We hope you enjoy growing in the MONT as much as we enjoyed designing it.10 year limited warranty on the frame and polycarbonate

Q: What is the type / thickness is the covering material
5 years ago- A: Cover Material: Polycarbonate The average thickness of the extrusion walls are 1/32” thick. The strength of the greenhouse is only partially determined but this thickness. The greater part of the strength of the greenhouse is in how many 9-0 degree bends each part has. Every time you create a new bend you strengthen and stiffen the part, making the overall structure more ridged. On average, our pieces have 12 90 degree bends in them. The other thing to consider is that we use 8 mm ( ¼”) twin wall polycarbonate that is designed to be structural and weight bearing. With how we lock the panels into channels built into the aluminum, the panels become weight bearing and more ridged.5 years agoHelpful?
