<p>A sealing assembly is disclosed which is adapted to maintain a sealed joint between relatively vertical and horizontal surfaces, being either straight linear or corner joints, whereby the vertical and horizontal boundaries defining such joints are subject to differential movement, creating joint expansion. The sealing assembly comprises a wall trim (10) adapted to be fixed and/or sealed to relatively vertical and adjacent horizontal surfaces (A and B), side trim (30) and side trim mitre pieces (40) adapted to sealingly engage the wall trims (10), and sealingly engageably connect across two wall trims (10) meeting together respectively, and while remaining sealingly engaged to the wall trims, are sealingly elongatable together. All three seal members (10, 30, 40) sealing co-operate to compensate for vertical movement by acting in a 'curtain', 'rail' and 'pelmet' like manner. The upper boundaries of the wall trims (10) act sealingly as a 'pelmet'. The complementary engagement points act as a 'rail', and the side trim and side trim (30) mitre pieces (40) combine to act telescopically as a wrap around overlapping 'curtain' to sealingly telescopically elongate as differential vertical surface movement dictates. An elastic horizontal sealing material is located between the wall trim (10) and the horizontal surface (A) to sealingly elongate to compensate for differential horizontal surface movement.</p> |
