Composites

Here is a recent article discussing the use of sandwich panels for the rebuilding of Haiti…

Here is a newly published patent from Airbus describing how to close and seal the edges of a composite sandwich panel.

A reader writes:

“I’m considering building a large walk-in freezer, approx. 2000 sq. ft. The freezer would be held at 0 degrees Fahrenheit or -18 degrees Celsius. From my research, the walls and ceilings would have to hold an R-value of 32 for those temperatures. Would you recommend using sandwich panels for this project? Or for freezers, is it better to go the traditional way and just install a pre-fab box? Are there sandwich panels with R-values that high? I’m only thinking of using sandwich panels for the walls and ceiling. The concrete floor will be refurbished another way to provide insulation.”

If you have any advice, please post a comment, or email info@sandwichpanels.org to pass on your suggestions.

Here is an interesting US Patent for a design used in cutting sandwich panels.
