JOINTEC GAS By PROFILITEC
Collection: Jointec
Product code: GAS
Type: Aluminium Flooring joint
Profilitec completes its joint range, introducing the GAS structural sliding joint. The GAS joint was conceived to be installed underneath flooring (tile, stone, etc.) and over the floor slab, differently than the GA range, which can only be installed under the slab. It is particularly suitable for commercial structures, airports, parking garages and railway stations with pedestrian and lightweight vehicles passage. The joint may be installed in the interstitial space between two sections of a building or between two building bays, according to technical specifications resulting from a structural evaluation of the building. Settlements of the structure, expansion and compression due to thermal excursion, shrinkage and structural bending are elements that create continuous movements and stresses in the flooring that often generate problems of cracking or premature detachment of the covering. It is therefore a good idea to provide an adequate grid of expansion joints during installation, choosing the type of joint and its location in consideration of the loads and stresses to which the cladding will be subjected and the different thermo-hygrometric linear expansion coefficients of the bedding and tiles and the possible interactions between different materials. The splitting of the surface and the screed underneath is in fact decisive in order to guarantee a workmanlike laying in both the adhesive and traditional methods. Always foresee a joint - In correspondence with a change in the substrate material and/or the casting joints. - In correspondence with pre-existing discontinuities in the substrate, such as structural expansion joints and different screed blocks. - At fixed elements such as columns and doors. - At changes in the laying direction. - At points where the tiled surface meets walls or containing elements. The resulting modules should be as regular as possible. As a general rule, the proportion between the two sides should not exceed 2:1.
