Riverstone MONT Greenhouse

The MONT Greenhouse is a robust, practical solution designed with the dedicated gardener in mind. Made in the USA, this premium greenhouse is designed to elevate your gardening experience to new heights, combining strength, functionality, and versatility in one package.

Whether you’re an experienced green thumb or an enthusiastic beginner, the Riverstone MONT Greenhouse is engineered to enhance your growing season, offering a versatile space where plants can flourish.

Just a heads-up: MONT used to go by the name Monticello. That’s right – the name got spruced up, but the greenhouses are still the same (or improved) garden havens you know and cherish. If Monticello Greenhouse rings a bell, you’re in the right place; welcome to the new era of MONT!

Key Features & Benefits of the Riverstone MONT Greenhouse

Versatile Sizing: Available in sizes ranging from 8′ x 8′ to 8′ x 24′, the MONT Greenhouse can accommodate gardens of various scales. Plus, it’s designed to expand in 4-foot sections, providing flexibility as your greenhouse gardening needs grow.

US-Grade Construction: Opting for a MONT Greenhouse means choosing a product that’s built right here in the USA with the highest quality extruded aluminum – using 40 lbs more than what’s found in the average imported greenhouse.

This superior construction ensures you receive a greenhouse far more robust than those made with the brittle and thinner aluminum commonly used abroad. Such strength is crucial, as a sturdier framework is better equipped to handle heavier snow loads and withstand stronger winds.

Each MONT Greenhouse is finished with an electrostatic paint for exceptional weather resistance, offering a level of durability and reliability that secures your gardening projects against the elements.

When you select a MONT Greenhouse, you’re not just buying a structure; you’re investing in a resilient haven for your plants, crafted to offer enduring support through every season.

Easy Setup: The greenhouse features an integrated base, allowing for straightforward setup on any level surface without the need for pouring concrete, simplifying the installation process (and reducing the installation cost).

Advanced Polycarbonate Glazing: The MONT Greenhouse distinguishes itself with its 8mm twin-wall polycarbonate glazing, a feature inspired by commercial greenhouse standards for unmatched durability and climate control. While others may opt for thinner, less costly materials, Riverstone Industries commits to this robust thickness to ensure your plants enjoy the best possible environment.

This choice mirrors the logic behind double-pane windows: it’s all about optimizing insulation. The result? A greenhouse that stays cooler in the sweltering summer heat and retains warmth during the chilly winter months.

This high-impact, UV-stable glazing not only shields your plants from damaging UV rays but also maintains a consistent temperature year-round for optimal growth.
