Carlisle Companies Incorporated announced that it has entered into a definitive agreement to acquire Henry Company, a provider of building envelope systems, from affiliates of American Securities LLC, a leading U.S. private equity firm.

Icynene-Lapolla, a global supplier and manufacturer of high performance, energy efficient building envelope solutions, launched a new low-pressure, low density, two-component spray polyurethane foam. 

The ways in which liquid and vapor move through our building envelopes are complex, and even today not completely understood; but the fact that lots of water can (and does) move through porous building materials is a phenomenon that rules over so much of the way we build.
