[vc_row][vc_column][vc_column_text css=”” woodmart_inline=”no” text_larger=”no”]Ceiling joints are designed to provide protection and sealing for joints, even during major seismic movements. They can absorb extensive multidirectional movements, thereby ensuring the free movement of buildings. This prevents structural collisions and thus ensures the durability of structures and the safety of everyone. Our roof joints are compatible with our fire protection seals.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column width=”1\/4″][vc_single_image image=”37358″ img_size=”full” alignment=”center” css=”” parallax_scroll=”no” woodmart_inline=”no”][\/vc_column][vc_column width=”3\/4″]\t\t
