Closed cell foam

[davidpm]

Is their any closed foam available at regular retail places.
Some times you just want a few square inches of something squishy and don't want do a whole mailorder thing.

For example a little backing for a stiffener rib to the hull.
A little insulation in the back of a locker.

Anything at the lumberyards? Maybe some foam used below grade for foundations?
What about those mats sold at camping stores to sleep on outdoors?

It would be nice to know what would work in a pinch.

I recently bought kneeling pads in the garden section at Home Depot.

You can always cut them to fit wherever you need them. They are about an inch or so thick and I have no concerns about getting them wet.

A good fabric store may have foam as well. Anything from there would probably not be good for an area that sees a lot of water.

Many of the old-style mats at the camping store were closed-cell foam 'd point out if you're just making stiffening ribs for the hull, cutting up garden hose can also work quite well to make the ribs. The strength is created by the glass, not what the glass is over.

Any good plastics retailer should sell Ethafoam as well as other types. Usually there are offcuts in a bin for not much money.
