Snap reasonable manner: polyurethane seal on both sides using rockwool roof dark button connection to avoid the risk of production leaky roof seams rock wool composite panels, the amount of saving accessories. Fixed firmly reasonable method: Polyurethane bilateral seal rockwool roof using a special self-tapping screws M6 and purlins fixed, can effectively resist typhoons and other external forces. Self-tapping screws provided between the two plates seam roof peak position retardant rock wool composite panels, using special waterproof construction, waterproof to avoid weak points. Short installation period: Polyurethane bilateral seal rock wool sandwich panel, since the scene without secondary processing, not only to keep the surroundings clean and tidy, does not affect the normal other steps, and can greatly shorten the installation cycle sheet, rock wool sandwich average daily plate mounting area of ??600 ~ 800m2. Drain board should determine the starting point has always been the position of the wind, the same starting row of roof and wall panels) Roof construction, the first in the purlin calibrate the starting point of rock wool composite board model, that is, along the span direction marked on each row plate purlin the starting point, each point of connection should be perpendicular to the longitudinal axis of the building, then continuing to affix a few boards to width restrictions and checks every plate misalignment in the width direction of the accumulation plate. Are not required to put the line will appear jagged and wide phenomenon.
