Profildeck Adaptater
Flat face to facilitate laying of timber decking boards.
Concave face to accommodate a paving slab packer for paved terraces.
Rot-proof aluminium joists.
The 2.4 m H55 Profildeck® aluminium joist simplifies and facilitates the process of creating terrace structures. This innovative joist is a two-sided profile: one side for timber or composite decking boards, and the other for paving. Profildeck® joists are ideal for use with large-format or narrow tiles. They also enable the use of multiple materials for the same terrace. Lastly, the Profildeck® solution also makes it possible to install hot tubs on riser pedestals. For installation details, download the instructions from the documentation tab.
The Profildeck® H55 joist can be used with all Essentiel standard riser pedestals (except 8/20 mm) and self-levelling riser pedestals, as well as with all decking joist support and Elevo® riser pedestals.
Profildeck® H55 joists are compatible with the full range of Profildeck® accessories.
Terraces for pedestrian and outdoor use only.
Aluminium joists offer a number of advantages over timber. Aluminium performs very well in terms of longevity (being rot-proof), and our joists are anti-corrosion treated, lightweight and easily transported and installed. If you want a durable solution that’s easy to maintain and extremely stable, Jouplast aluminium joists are an excellent choice.
However, if your preference is for a more economical option and a more natural appearance to accompany timber decking boards, then timber joists may be more appropriate, as long as you are prepared to carry out regular maintenance.
Although we can tell you the approximate number of joists you will need per m2 based on your choice of terrace surface, it is not possible to quantify the precise number of aluminium joists required, except on a project-by-project basis. Nevertheless, we can say with certainty that :
Centreline spacing is the distance between joists. For a precise calculation, you can send us the details of your project, but you will soon be able to make the same calculation using the Jouplast® app.
The durability of a terrace built using aluminium joists depends on a number of criteria :
of existence at your service
to bad weather
and environmentally friendly
