摘要：<p>The joint has a height to match the thickness of the roof facing, is 2cm wide, and has a hollow rectangular section. It is made of a hard extruded plastic material that allows for the expansion and contraction of the roofing material while maintaining a solid waterproof seal. The bottom and top side of the joint (2, 3) are concave and the laterial walls (4) have projections either male dove tail, solid spur or thin projecting wings, which bed into the roof facing. The facing is made from cement mortar, concrete flags or ceramic tiles.</p>
