Haitian workers were trained on site to install the steel SIPs, which are made of an EPS core sandwiched between 26-gauge galvanized steel skins. Here, a crew member cuts the gable profile with a Kett panel saw.
The panels have a T&G friction-fit edge profile and attach to each other and to the galvanized metal base track with screws. The cottage was erected on the existing concrete foundation of a home destroyed by the 2010 earthquake.
A pair of 8-foot ladders was the only lifting equipment on site. Fortunately, even the 24-foot-long 6-inch roof panels were light enough to be hoisted into place by hand.
Once the shell was assembled, workers cut out openings and installed the windows and door. The panels’ factory-painted coating serves as the interior and exterior finish.
