Foam board (DAS)

Other Names:

XPS board, $TreeBoard (as found in $Tree stores in USA), DAS2030W5 (Bunnings)

Description:

XPS with paper covering. The NZ version by DAS has a much more permanent glue than the USA $Tree Board. Comes in 760 mm x 500 mm x 5 mm size (30" x 20"). Paper can be removed by sanding the shine off the paper and spraying with LRM200D Label Remover. An alternative paper remover is isopropyl alcohol or Rubbing Alcohol. Note Rubbing Alcohol might be ethanol (ethyl alcohol). Possibly cheaper than spray label remover. Always remember to wait, even up to 1/2 hour before trying to peel the paper off. Warning - Helmar REMOVE cleaner eats foam.

Art shops may have other thicknesses and sizes.

Advantages:

Easy and quick to use. Glues easily with PVA or hotglue.

Disadvantages:

Paper needs to be removed if a curved wing surface is required.

Handling:

Cuts easily with a knife. Heating with a hotair gun will allow forming over a former or even just a wing spar to get a curved wing surface.
