Installation of HardiePlank


When installing cement board siding, whether it's lap board, shake or batten board, it is important the proper systems are in place. As a preferred sliding contractor, Reaction Exteriors goes above and beyond to make sure your siding is installed correctly and that water will never find its way into your home. We install 2 vapor barriers, DuPont Tyvek, followed by Benjamin Obdyke Hydro-Gap drainable house wrap. The entire field is detailed with 5/4" Azek. Head flashings are installed above foundation lines and horizontal Azek trim. All head flashings are sealed with DuPont flashing tape and properly integrated into the vapor barriers. The cement board product is installed to manufacturers specifications with aluminum flashing present at all butt joints and touch up paint applied to all cut ends. The siding is finished with caulk detail and every board is wiped down with a mild cleaner to leave it looking brand new!
