<p>The system of profiles and the connection between them allows free block expansion and the transverse joint section has a tenon (C) centred on this section. The top and bottom wings of the tenon (I) are parallel to assure no play between adjacent edges of blocks placed side by side whatever the horizontal play between the edges due to expansion or contraction. The profiles have at their top part a hem or border (K) that allows the fitting of positioning jamb (L) while at the bottom it has a rigidity heel (M) placed on the side opposite the tenon.</p> |
