Taking "Green" construction to an entirely new level, the Leopold family of Fauquier County, VA built their house using straw bales... and, of course, Henselstone windows and doors. Check out the Piedmont Virginian autumn 2009 edition for details on this unique constrcution method...

Henselstone has finished development of a highly energy efficient hardwood window. The 3 1/4" profile allows integration of triple insulated glass panels while appearing slightly sleeker than the traditional 2 3/4" frames. With this system Henselstone can now passive house certified...

The German government continues to put its money where it counts. Tax credits for glass manufacturers produce a steep discount for all triple insulted glass, even the one you buy from us here in the US. 

Treated lumber corrodes fasteners and many surrounding metals. Without nailing flanges, Henselstone's tilt and turn window system installs directly into masonry walls and does not require furring of the openings. 

Henselstone Window and Door Systems actively sponsors the USGBC (United States Green Building Council) to promote design and use of products that reduce Green House gas emissions.
