Beautiful, Practical, & Functional

We have designed every detail & hand-crafted each piece of our outdoor furniture for over 45 years in Alton, Illinois. That same dedication & craftsmanship goes into the manufacturing of our Greenhouses. Customers consistently respond with their appreciation for the beautiful, yet practical & functional design for easy set-up, minimal maintenance, and lasting durability to withstand the test of time. New Frontiers Greenhouses and Outdoor Furniture add value and beauty to any home & landscape.

Years of research & design went into our cedar greenhouses, and the end result proves just that. The interior features are listed below.

  • We use only the finest grade of clear Canadian Western Red Cedar, This is important because it is straight-grained and holds its shape. No twists or warps like the other woods.
  • Western Red Cedar contains natural oils that prevent decay.
  • Western Red Cedar absorbs & releases moisture with minimal expansion & contraction. Your greenhouse remains solid and tight for years to come.
  • Cedar greenhouses have much higher insulation properties than metal. There is substantially less condensation & temperature fluctuation.

While cedar provides outstanding interior greenhouse performance, if exposed to the elements year-round, maintenance would be required. We have eliminated that time-consuming expense.

  • Each New Frontiers Greenhouse is clad with AZEK material, AZEK delivers a “like new” appearance regardless of the weather.
  • It requires no paint or sealer for protection.
  • It is impervious to moisture, insects, mold, and mildew.
  • AZEK is durable, long-lasting, and has a limited lifetime warranty.
  • AZEK material limits shortfalls associated with other composite decking materials as it contains no wood fillers.

The base walls provide strong structural support and protection for your greenhouse.

  • We use HardiePanelfiber cement board with a beautiful stucco finish..www.jameshardiecommercial.comHardiePanel is designed to last up to 30 years against cracking, rotting, hail damage, termites, and other problems with exterior exposure.
  • It can be stained or painted in any color to match your décor.
  • Since the HardiePanel is located at the base around the greenhouse it provides protection against lawn mowers, etc. & also allows for the area underneath the shelves to be out of view from the exterior of the greenhouse.
  • Foam insulation can easily be added to the interior base if desired for extra insulation in the winter months.

This is the material of choice for both commercial and residential greenhouses. Gallina USA, 8 mm twin-walled polycarbonate sheets are tough and lightweight.

  • Hi-impact resistance & excellent clarity.
  • Plants respond best to diffused light, and the polycarbonate twin-walled panels help diffuse sunlight to prevent burning.
  • Superior insulating qualities and energy savings.
  • UV stabilized exterior layer provides high resistance to yellowing.
  • 10-year limited warranty against discoloration, breakage, and loss of light transmission due to weathering.

Our Greenhouses are available in several sizes. All models have 6’ 7” sidewalls providing comfortable access and a substantial increase in growing space.

    • Each kit includes all parts pre-cut, pre-drilled, and pre-assembled where possible.
    • Our doors are pre-assembled and all metal parts are galvanized.
    • Clear, illustrated step-by-step assembly instructions accompany each kit.
    • We will provide a base plan illustrating the footprint of your greenhouse and suggestions for building the base.
    • Sizes available with 10/12 roof pitch:
      • 8.5’ x 8’ x 10’ 3” (at the peak)
      • 8.5’ x 12’ x 10’ 3” (at the peak)
      • 8.5’ x 16’ x 10’ 3” (at the peak)

(Remember, the larger your greenhouse the less your cost per square foot of growing space.)

  • Optional Shelf Kit– To maximize your growing space, we offer a pre-fitted shelving system that mounts to the sidewalls & back wall. The lower shelf is 2′ deep and the upper adjustable shelf is 14″ deep, both are constructed with a cedar frame, using a plastic 1″ thick dura bench material.

We include many features that are either not available or would be costly add-ons from other manufacturers. See for yourself . . . . . . .

  • 3-speed exhaust fan
  • Motorized intake shutters
  • Thermostat
  • All of the conduit and fittings for the installation of the above components with wiring diagram.
  • Polycarbonate sheets are pre-taped. (These sheets are designed to accept foil tape on the top edge and vent tape on the bottom. This is a time-consuming task- WE DO IT FOR YOU!)
  • 32” wide door with screen panel for the summer ventilation.
  • Quality locking door and hardware with entry overhang.

In all instances, the base of your greenhouse should be installed on a flat, level & square foundation. When you order your greenhouse, we will provide you with a base plan showing the footprint of the greenhouse model you ordered. We will also provide guidance & recommendations as to its construction.


Dear New Frontiers,
The greenhouse which we purchased from you turned out very nice. It is really attractive and quite functional. The man who delivered it here from your factory in Illinois was quite helpful and the directions were easy to follow. Today is November 1st and I am enjoying tomatoes growing in pots in the greenhouse. I am really looking forward to next spring when I can get the plants for the garden started in the greenhouse.
I am very pleased with the greenhouse and everyone at New Frontiers has been really helpful during its construction.

Sincerely, Alan

Dear New Frontiers,
I purchased an 8′ x 16′ greenhouse this past year, I wish to tell you that it was a fantastic purchase!! It went together extremely well. All parts and directions were well thought out and the materials were of high quality. The few questions I had were promptly & satisfactorily answered. Thank you!!

Dear New Frontiers,
I am having the time of my life with my greenhouse!!! I have been growing different seeds over the years and this year I am growing tomatoes thru the winter and have been getting fresh ripe tomatoes in the last few weeks. Next year I plan to start them earlier. My only regret is that we couldn’t afford a larger greenhouse model, we purchased the 8′ x 8′. I really am so happy having the greenhouse & would recommend it to everyone. So glad that we bought it!!

Sincerely, Linda
