See full version: Top 4 Installation Techniques; Recommendations for Styrofoam™ Brand XPS Insulation
This is the single-most popular question. Here’s the answer: Adhesives from DuPont offer dependable, long-term service for a wide variety of applications and are compatible with most construction materials. The most commonly used adhesive with Styrofoam™ Brand XPS Insulation is Great Stuff Pro™ Construction Adhesive .
There may be other adhesive manufacturers compatible with XPS insulation. Check the adhesive container or with the manufacturer to determine if a particular adhesive is compatible with polystyrene-based insulations.
Have you ever seen a home or building built the same way twice? Given the specific needs of each project, installation and compatibility questions are among our top of our building science experts.
Dupont Styrofoam™ Insulation (Blue Board) is a nonstructural, rigid board insulation manufactured of Extruded Polystyrene Foam (XPS). Blue Board can be used both on exterior and interior walls to give you a continuous insulation barrier that can increase effective R-value of the wall by up to 20%. First manufactured by Dow in 1941, Dow/Dupont's blue colored extruded polystyrene has been an industry leader ever since. Extruded Polystyrene Foam offers high, long-term R-value and excellent compressive strength. Blue Board's closed cell structure and lack of voids resists moisture penetration thus increasing its thermal efficiency and protecting underlying materials from water damage. When used with Weathermate construction tape to cover seams and Great Stuff sealants to seal gaps, Dupont Styrofoam™ insulation board provides a barrier against air leakage and infiltration.

The Rutan ships and their derivatives have their wings, canards, winglets, and control surfaces carved out of the stuff. Fuselages of same ships have other cores. more
In the '70s Ken Rand created his KR-1 using a set of Taylor Monoplane plans. Instead of cutting all those hundreds of little pieces for the ribs he just cut a few from plywood and used them as patterns to sand styrofoam to shape between them. He used foam instead of plywood on the fuselage, IIRC, and in the tail too. Covered it all with polyester fabric and epoxy resin. Polyester fabric is lighter than glass but stretches a lot more, too. Same fabric as used on fabric-covered airplanes. more
