extremegreen Wallboard

HIS INNOVATIVE WALLBOARD defies easy
categorization. It’s made with magnesium oxide with no
organic fillers or resins, and comes in quarter-inch, half-
inch and 5/8-inch thicknesses. The company also sells tile
T backer and other products of the same material.
We talked with extremegreen CEO Sam Catling at Greenbuild. He
says the product is currently imported from China. GB: “Do you have
plans to open a U.S. manufacturing plant?” Catling: “No comment.”
We’re hoping that means we’ll one day see U.S.-made versions of
this product, which has a Class A1 fire rating, with zero flame spread
and zero smoke developed rating.
After a flooding event, Catling says the product can just be washed
off with a mild bleach solution and will continue to perform. Perhaps
the best feature, however, is that the wallboard can be used in place
of interior drywall. Seams would still need to be taped, of course,
and this might require some clever product choices to keep up with
the wall’s strong performance in the face of mold, water and fire.
Another perk is that fixtures, art and other heavy objects can be
hung directly from this material, without blocking. The product is CREDIT: EXTREMEGREEN
more suited to nailing than screws when attaching to studs.

3M Impact-Resistant

Window Film

S THE LAST HURRICANE SEASON
demonstrated, it’s not only homes in high-risk
zones that can be damaged by hurricanes. One
of the most-common causes of major damage
A to homes old and new is penetration, followed
by “blowout.” This can happen through a soffit, a vulnerable
door or window. Like more expensive impact glass, impact
film will not necessarily prevent all damage to a home
in a major blow. But as an affordable—and surprisingly
effective—method to strengthen glass, it could certainly be
used as a retrofit glazing reinforcement for homes a little
further from the coast, yet still at risk. The risks of airborne
debris in older neighborhoods are very high. Impact film
could mean the difference between a total loss, and a little
water damage.
