Portable Outdoor Classrooms

Shelter Systems' Portable Outdoor Classroom Yurt Dome Tents have been helping teachers around the world by providing dry bright classrooms that could be put up in minutes. Shelter Systems' Portable Outdoor Classrooms offer the best value because they are strong, durable, watertight, wind-resistant, pleasant to be in, easily set up, and affordable.

The 18' Portable Classroom Shelter Systems' Portable Classrooms are dome-shaped Geotensic™ shelter structures. A dome is stronger than any other shape of the same volume. Because of its curved shape with no corners, there are no weak points. Our patented structure is drum tight, waterproof and wind-resistant.Known for their lightweight construction as well as for the large amount of light they let in, they are made with a strong, tear-resistant fabric and non-puncturing tarp fasteners. They are truly portable and guaranteed to be leakproof.

30' Portable Outdoor Classroom Shelter Systems' portable classroom structures have the poles on the outside with the covering suspended under the frame via Shelter Systems' own Grip Clip tarp fasteners. The frame and the covering are not in direct contact. The important benefits from this design are that the covering is under constant, even tension so that the tent will not flap in the wind, which would otherwise shred it. The poles cannot rub against the covering, thereby wearing holes in it. Also, since the poles and covering are not touching, there is no temperature buildup to degrade the fabric at contact points.The shingled panels of our Portable Classroom tents overlap each other by 6", making the structure stronger and completely leakproof. The shingling also allows the structure to breathe. The buildup of moisture is driven out through the overlapped panels by vapor pressure and does not condense inside the tent.Shelter Systems' patented Grip Clips tarp fasteners join the dome's cover to the frame. Grip Clips also fasten the shingled panels together, providing greater strength than sewn seams or any type of grommet because they do not puncture the cover, which would allow rain to enter. In addition, the Grip Clip grips a large surface area of the material which prevents the wind from tearing the tent.

18' Portable Outdoor Classroom Durable Materials
Shelter Systems' Portable Classroom Yurt Dome Tents are made wholly of a super strong, tear-proof, woven rip stop film which will not rot or mildew. The covering effectively excludes rain, dampness, wind, cold, and sun. The completely waterproof covering and the shingling's breathability make a rain fly unnecessary. The covering is manufactured in three layers which are heat bonded together. It is UV-stabilized to withstand up to 3 years of full sun exposure. The white color of the covering reflects the heat of the sun and provides 40% shade.

The frames are constructed of strong, long lasting, resilient, UV-stabilized, Class 200, 1 1/4"-diameter (3.5 cm.) PVC tubing.Affordable
Our waterproof design doesn't require a rain fly and the particular dome shapes we use utilizes material efficiently, so Shelter Systems' tents use less material. The high performance covering is affordable. Because of the design and our tarp fasteners, our

tents are labor efficient to build. These factors make for reliable and affordable Portable Classrooms.Comfortable Living Space
Shelter Systems' Portable Classroom Tents are light filled and well ventilated. The white covering creates a pleasingly bright interior. Shelter Systems' 18' Portable Classroom Tent has four flap doors evenly spaced around the dome for good cross ventilation and light. The door coverings close automatically so you can go in or out quickly. There are no zippers to fumble with or break. Over each door is a translucent skylight window which allows 90% of the sunlight (more than glass) to pass through it while preserving the privacy of the people within.Shelter Systems' Portable Classroom Shelters are winter ready tents. They do not require a fly or liner for winter use. They are completely water tight and will not leak. Yet because our their shingled construction moist air is driven out through the shingling by vapor pressure. Shelter Systems' Portable Classroom Shelters being dome shaped have a minimal surface area for their volume and are thus easy to keep warm with a stove (installation instructions are included with each tent).

Since the panels of our domes are shingled, overhead ventilation is easily attained by inserting a lightweight object (eg, an empty soda can) between several panels (two "vent tubes" are included with each dome). When the can is removed, the panels snap shut and are watertight. For maximum ventilation the walls themselves can be rolled up, transforming the dome into an Opened-Arch Form.The dome shape has other comfort features: The interior can be divided into "rooms." The tent has more volume than a flat-sided one and therefore feels, and is, more spacious. The shape is more heat efficient because less fuel is needed to heat it plus the heat circulates more evenly. The cover of the dome is easily cleaned with a damp cloth.Comparing Different Domes warming hut

The 18' is our most popular dome. It's 254 square feet and is the size of a small room. We also have 14', 20', and 30' Portable Outdoor Classrooms. As the tents get larger, there is a greater increase in volume in relation to the increase in diameter. So the 18' Portable Outdoor Classroom feels twice as big as the 14'er! This is because the size in diameter extends out in all directions, creating a large increase in volume. Our drawings effectively illustrate this. Since the surface area of the covering does not increase as rapidly as the volume, the larger domes are less expensive for the usable space inside.

The different domes have different numbers of doors. The 14', 18', and 20' Portable Outdoor Classrooms each have four flap doors evenly spaced around the dome for good cross ventilation. The 30' Portable Outdoor Classroom has eight doors.Shelter Systems' Portable Classroom Yurt Dome Tents perform excellently in strong wind due in part to their many, evenly space anchor points. The 14', 18', and 20' Portable Outdoor Classrooms each 12 anchor points. The 30'er has 20 anchor points.Complete and Adaptable Setting up a dome

Shelter Systems' Portable Outdoor Classroom Yurt Dome Tentscome complete with poles, 12" long quality Durapeg stakes, guy lines for extreme wind settings, ventilation tubes, spare parts (Grips Clips and pole connectors) and a Shelter Systems' Instruction Manual that details floors, site selection, anchoring, cooling, winterizing, and stove installation. Our tents are ideally suited for most climates; however, they can be further adapted for use in extreme climates. For the extreme cold, where fuel is in short supply, we offer a full liner. For extreme heat, we offer net doors and a sunshade which blocks one hundred per cent of the sunlight. Other accessories available are rain porches, floors, etc.Easy Set Up
The 18' Portable Classroom Yurt Dome Tent can be set up by one person in 30 minutes without tools. Insert the interchangeable poles into factory-attached connectors spaced evenly over the cover. The poles bend slightly when inserted, tightening the cover into a wind- and waterproof shelter. The tent is freestanding requiring no guy lines and can be moved into the desired position or location without taking it down. The Shelter Portable Classroom can be taken down in 5 minutes: just remove the poles and roll up the covering.Storage

You get a lot more volume for your money as you go up in diameter. When you step inside the 18' yurt after being in the 14' yurt, the 18 ' er feels twice as big. The 20' yurt feels twice the size of the 18' yurt. This is because the extra feet in diameter extends out in all directions (including up) creating a large increase in volume. Since the surface area of the covering does not increase as rapidly as the volume, the larger domes are less expensive for the space you get.
