Knauf HydroProof®: the solution for the most demanding wet areas, now fully available

It is notably used for the construction of exterior ceilings in all types of buildings, or indoors for partitions and ceilings in particularly demanding wet areas ; for example in communal showers and changing rooms, aquatic centers and spas, or swimming pools and areas with direct communication with the pool.

Knauf HydroProof®: a new DTA (Technical Approval Document) for interior partitions and linings

Complementing the CSTB Technical Approval Documents (DTA) already available for interior and exterior ceiling applications, a brand new DTA now addresses installation in partitions and linings, with single or double facing. This new DTA reinforces Knauf HydroProof®'s position as the benchmark technical solution for high-humidity environments , further reinforcing the system's suitability for specifiers, designers, and major plastering companies, guaranteeing them durable and insurable structures.

Available in two thicknesses (12,5 mm and 18 mm), Knauf HydroProof® BA13 and HydroProof® BA18 plasterboards have expanded and certified applications. They are suitable for ceilings, partition walls, and linings in a wide range of buildings, including residential properties, public access buildings (ERP), and buildings subject to the French Labor Code. 

Their implementation is now officially validated, both in private EB+ classified premises , and in collective EB+ or EC premises (excluding areas subject to high pressure cleaning and grease production).

This classification, defined by the CSTB guidelines (notebook 3567_V2 of November 2021) therefore attests to the ability of the Knauf HydroProof® board to withstand the most intense humidity conditions in the most demanding applications : collective showers and changing rooms, aquatic centers and balneotherapy facilities, commercial laundries and launderettes, or swimming pools and rooms with direct communication with the pool.

Knauf HydroProof®: a plasterboard with multiple advantages

Easy to cut and install (10,8 kg/m² for BA13), the Knauf HydroProof® plasterboard (3000 or 2600 x 1200 mm) is characterized by its high surface hardness, guaranteeing the mechanical resistance required in the intended premises. It also ensures easier finishing work thanks to its tapered longitudinal edges . Holding both "A+" certification for indoor air emissions and "Excell Green Zone" certification for sensitive environments (food industry), it also boasts a fire rating of A2-s1,d0.

Knauf HydroProof®: more than just a plasterboard, a complete, proven system allowing for cost-effective sizing.

To guarantee the performance and durability of the Knauf HydroProof® system and contribute to the overall integrity of the structure, Knauf complements this certified offering with a complete range of specific "waterproof" accessories . This range of accessories includes numerous references for pivot hangers, adjustable hangers, studs, rails, furring strips, splices, threaded rods, screws, water-repellent coatings, joint tapes, etc.

Another advantage of the 100% Knauf system, according to Nicolas Mergenthaler, Knauf Interior Design Product Manager: "it also allows for advantageous sizing of single-layer partition walls made of Knauf HydroProof® BA13 or BA 18 boards. Indeed, the maximum height of a 98/62 partition wall, for example, with single cladding in single studs spaced at 0,90 m centers, will be 3,50 m with Knauf HydroProof® BA 18 and will only be 3,30 m with other boards on the French market."

Finally, always keen to provide the best possible support to professionals, Knauf is making available to them a brand new "Guide to choosing interior fittings in humid environments" to help them choose the system adapted to their project.
