Are there any foams on the market that are considered  environmentally-friendly?

Yes! There are flexible foams on the market that are made using non-oil based chemicals such as soy, and American Excelsior has a wide variety of optional “green” foams marketed as Earth-Cell™.

What is a board foot?

A board foot (b/f) is the industry standard for pricing flexible foam and is basically the same method used in the lumber industry to calulate wood. One board foot is: 12″ x 12″ x 1″. To calulate the number of board feet, simply take the length x width x thickness and divide by 144. Example: A 24″ x 24″ x 4″ piece of foam has 16 board feet.

What does IFD stand for?

Indentation Force Deflection which is a measure of the load bearing capacity of flexible polyurethane foam. IFD is generally measured as the force (in pounds) needed to compress a 50 square inch circular indentor foot into a 4″ thick sample, typically 15″ squarer, to a stated percentage of the sample’s initial height.  Lower number ratings such as 15#-20# is soft and generally used for back or pillow type applications. The higher the number, the firmer the foam will be. Also used to be called “ILD (Indentation Load Deflection)”.

What does the “density” of foam mean?

Density is the measurement of the mass per unit volume and it is measured in pounds per cubic foot. Density is sometimes confused with the firmness of a foam. If you took a 12″ x 12″ x 12″ block (1 cu/ft) of a foam that is supposed to be a 1.8# density, it should weigh 1.8# with a normal tolerance of plus/minus .5#.

What does “reticulated foam” mean?

A Reticulated Foam is characterized by a three-dimensional skeletal structure with few or no membranes between strands. Reticulated foams are generally used as filters, acoustical panels, and for controlled liquid delivery.  Reticulated foams are sometimes referred to as “filter foams”.

What does TDI stand for?

Abbreviation for toluene diioscyanate, a chemical used in the production of polyurethane foams.

Is there an easy way to cut foam at home?

Yes- Using normal safety precautions when cutting, an electric kitchen knife works quite well on most foams.
