At Cersaie 2023, the company has introduced membranes and systems to complement its existing range of indoor and outdoor solutions, designed to satisfy all aesthetic and functional requirements.
Among the products being launched is the Prodeso Heat Grip 5 System, a patented electric heating system designed for both floors and coverings, which provides heat only where it’s needed in minutes, the company says, resulting in a cost-effective solution that saves time and energy. The system is made up of the Prodeso Heat Grip 5 Membrane and Cable. The membrane, at 5.5mm thick, is designed to fit any floor or existing surface and, with an improved structure, allows the heating cable to be perfectly fixed. The system can be laid with standard cement-based adhesives and, thanks to its uncoupling, waterproofing and vapour control properties, can also be laid on cracked or hygrometrically shrinking substrates. The Prodeso Heat Grip 5 Cable is equipped with many resistances in parallel circuit which, in the event of damage, do not interrupt the heat transfer of the entire system.
In addition, the company’s latest generation Wi-Fi thermostat improves the system’s energy efficiency. The Prodeso Heat Grip Thermostat can be programmed remotely on a daily basis, with all settings and schedules adjustable through an application on Android or Apple devices. The patented system is also available in the self-adhesive version Prodeso Heat Grip 5 Stick and as the Prodeso Heat Grip 8 System, with a membrane thickness of 8.5mm.
The company has also developed what it describes as an ultra-thin membrane, Prodeso Drain 4, at 4mm thick, which exceeds the performance of its predecessors and reportedly offers significant advantages. Installation is said to be easier and more accurate, with laying times reduced. The 4mm membrane is also said to give indoor floors a longer lifespan, eliminating the need for costly maintenance over time. It consists of a cyan-coloured sheet of high-density polyethylene (HDPE) with 4mm high square reliefs. A polypropylene spunbond is bonded to the underside of the sheet. This ensures that the membrane is bonded to the substrate.
With its uncoupling ability and high capacity for correct vapour drainage, Progress Profiles says, Prodeso Drain 4 is a suitable choice even for problematic substrates such as wood, cracked screeds or overlaps. In fact, the membrane is designed to neutralise the differential movements that can occur between the substrate and the floor covering, thus preventing damage to the tiles, and it does not bind to any joints in the substrate. The adhesive used to lay the flooring dries quickly and evenly, the manufacturer says, thanks to the cavities created between the polypropylene drainage fabric and the polyethylene sheet: these promote micro-ventilation, drastically reducing the rise of triacetates present in the adhesives and the appearance of efflorescence in the joints. Finally, in the case of underfloor heating, this “air chamber” allows better heat distribution and a reduction in thermal inertia.
In the Prodeso Drain 8 System version for exterior use, with a minimum thickness of 8mm, the membrane is completed with an elastic polyethylene and polypropylene strip and a two-component waterproof adhesive, which ensures a good waterproofing of exterior coverings and reduces resin migration on the surface. Finally, both the indoor and outdoor versions are practical and quick to install, making it easy for installers to carry out even the most complicated renovations. This exterior system can be combined with the company’s Proterrace Double Drip, it says, to protect the outside corners of balconies and terraces and to finish off the edges of the floor. Thanks to its two drainage holes, this system allows water to drain off properly if the seal between the edge of the tile and the profile becomes detached, preventing water from penetrating the screed.
