Schluter 25 Uncoupling System
SCHLUTER 25 UNCOUPLING MAT
Schluter 25 uncoupling mat is a polyethylene membrane with a grid structure of square cavities, each cut back in a dovetail configuration, and an anchoring fleece laminated to its underside.
Schluter 25 uncoupling mat is adhered to the substrate using a PSA Adhesive. The anchoring fleece on the underside of the Schluter 25 uncoupling mat is semi bonded, allowing the mat to be lifted at any stage.
Designed specifically for ceramic tile and dimension stone installations, Schluter 25 uncoupling mat serves as an uncoupling layer, slip layer and vapour management layer that accommodates moisture from beneath the tile covering. Schluter 25 uncoupling mat performs all these functions while still providing adequate support/load distribution for the tile covering.
The New Zealand building standard E2 external moisture determines that tiles can no longer be adhered directly to waterproofing on exterior timber decks.
Schluter 25 uncoupling mat complies with the NZBC E2/AS1 as an alternative solution in Section E2/AS1 18.104.22.168 removable surfaces.
Schluter 25 is included in the duroTUF TPO and Gripset liquid membrane systems BRANZ Appraisal as an accessory.
ADVANTAGES OF SCHLUTER 25
- only 3mm thick, specially designed for tiling over.
- allows the building owner to have a tile and grouted surface finish.
- cracked tiles can very simply be replaced without removing the Schluter 25 uncoupling mat.
- isolates the tiles from vibration or seismic movement.
- can be applied directly over green concrete where no membrane system is required and tiled over immediately.
- can be used where several different substrates merge to form a bond breaker system.
- is inert, cannot affect any other products or systems.
- is water resistant.
- has vapour management and release channels in its design.
SCHLUTER DITRA SOUND
Schluter Ditra Sound tiles are made of a heavy polyethylene mat which has an anchoring fleece laminated onto both sides.
Schluter Ditra Sound does not rot, is waterproof and crack bridging. It is resistant to the effects of watery solutions, salts, acids, alkalis, organic solvents, alcohols and oils.
The Schluter Ditra Sound can be directly adhered to the Schluter 25 uncoupling mat with a specified tile adhesive.
We recommend duroTUF TPO Fleece back membrane to be used with the Schluter Ditra Sound system to ensure every element of the system with contribute FIIC test results.
The Schluter 25 uncoupling systems must be installed over smooth finished waterproofing membrane systems. Waterproofing Systems NZ Ltd uses duroTUF TPO 1.5mm thick smooth or fleece back and Gripset 2P SBR liquid membrane systems.
If the application is to be installed over alternative systems, check with the supplier with regards to membrane compatibility and warrant conditions.
Waterproofing Systems NZ Ltd has a complete set of detailed drawings for the Schluter 25 uncoupling system installed over duroTUF TPO and Gripset 2P systems.
When installed in accordance with the specifications Schluter 25 uncoupling mat has a 15 Year warranty if installed by an approved Waterproofing Systems NZ Ltd licenced LBP registered applicator.
Waterproofing Systems NZ Ltd can supply a combination warranty which includes the membrane system and Schluter 25 in a single warranty document.
