The Frame Expandable is a modular type tent that has proven popular at East Wind. They are expandable in 16 foot sections and can be fitted with a liner although only in complete 16 foot sections. Frame Expandables can be found in either Duck Canvas or Polyvinyl material.

Interior volumes are large when no liner is fitted but reduces dramatically when a liner is added.

Frame Expandables have a many large windows which offer excellent ventilation and allow a good bit of natural light in.

There are no vestibules available for the Frame Expandable.

You can find a manual that covers the Frame Expandable here:

Selecting a Frame Expandable

  • The Frame Expandable is generally a more expensive option but is a good bit easier to maintain since each individual piece of canvas or vinyl are small enough to be easily handled and as such are far less prone to being ripped.
  • The canvas tents are generally fairly old. They will quite typically be found with a great number of patches and repairs which are fine so long as they are solid.
  • You will want to carefully examine the patches to be certain that they are secure and that the glue holding the patch has not dried up and started to crumble. If the patches are loose, plan to repair or replace them prior to the event.
  • Carefully examine the condition of the duck canvas. Once the canvas starts to rot, it tears quite easily. If you are unsure, use a butter knife seeing if you can push it through the material. If you suspect dry rot do not bother taking it to East Wind, it will come apart in very short order.
  • Check your canvas for water repellency. If water runs off like a ducks back then it is in good order. If not, then invest several gallons of canvas treatment such as Nikwax or Canvak.
  • The polyvinyl tents are all a good bit newer but have a few issues of their own.
  • The polyvinyl tents have cotton canvas webbing reinforcements running along the seams. If the vinyl tent was stored wet, the cotton webbing will fail leaving the vinyl unsupported and prone to catastrophic failure in high winds.
  • Early polyvinyl tents were not well sealed along the seams. If the seams are not properly hand sealed, these tents will leak severely.

Lessons learned regarding heating the Frame Expandable

In 16x16 configuration with a liner installed, it takes very little to heat a Frame Expandable. Good results have been had using the Hunter Space Heater Small. With the liner out, the interior volume increases greatly and a larger heater would be required to achieve good results.

In 16x32 configuration with liners in use the "divider" effect of the liners tends to sequester all the heat in the section that has the stove which results in half of the tent being excessively warm while the other half is quite cold. Measures should be taken to rig the liners in such a manner as to allow the maximum transfer of heat from section to section or a pair of smaller heaters could be used instead.
