For light-weight and easy to move, consider honeycomb core cardboard (usually 1 - 1 1/2" thick) that is treated with fire retardant / intumescent paint. It's not long-term durable, but it is quick to make-up and doesn't break apart like styrofoam or other foam-core products that can produce toxic fumes if they burn.
If you want to make the honeycomb panels more durable (the edges are easily ding'd), then wrap them with a continuous layer of fire-retardant (FR) muslin that is attached with spray-glue or brush-on glue.
Standard white pine framed fabric-covered flats are really pretty cheap to build and light weight, and it's always good practice to have the class build them. Of course, you have to treat the wood and muslin with fire retardant for these, too.
Too frequently I see Unit Sets pieces that are not treated with fire retardant. C'mon folks! It's been law to build scenery and props from non-combustible materials for over 100 years now. No more excuses! Just do it. Fire-proofing treatments are readily available and affordable. Set a good example for the students and let it be part of their understanding about how stuff is built and works in the theatre. Ignoring / omitting this from the teaching process just promulgates bad practices. The schools pay hundreds, ney, THOUSANDS of dollars every year for school bus safety, fire safety, and football helmets - they must understand that this is a Fire Code requirement. It is NOT OPTIONAL.

Subject: Light Weight Touring Flats
I really need advice for my one-act competition set (The Savage Dilemma by John Patrick). It's an interior and it has to be free standing and fit in a 10 x 10 space. I need very lightweight and very durable 4 x 8 wall (flats?) to be hinged like a fan. Does anyone know what I should buy? Thank you in advance!
