A Weather Resistive Barrier Solution for Rainscreen Claddings

More Info


SOLITEX EXTASANA ADHERO® provides the ultimate weather protection layer for your walls and roofs under all conditions. Fully adhered to rigid substrates, SOLITEX EXTASANA ADHERO® provides ultimate protection to the building from wind, driving rain and other external sources of water, whilst allowing any internal moisture to escape through the vapour permeable, non-porous TEEE layer.


TESCON EXTORA® weathertight sealing tape is an essential component of all weather-resistive barrier (WRB) systems. It is compatible with membranes and underlays as well as rigid sheathings, rigid wall underlays and rigid air barriers (RAB). TESCON EXTORA® is weathertight and vapour permeable. It is flexible, easy to cut, and has a simple to remove release paper, ensuring maximum productivity during installation.


TESCON NAIDECK is a double-sided self-sealing strip, designed to seal penetrations of purlins, battens or studs. It can be fixed directly to, or behind, your weather resistive barrier (WRB). It forms a durable seal around any nail or screw penetrations, and is an essential part of low-slope roof systems. TESCON NAIDECK is compatible with the pro clima SOLITEX MENTO® and SOLITEX EXTASANA® membranes, as well as rigid sheathings, rigid wall underlays and rigid air barriers (RAB)

pro clima SOLITEX EXTASANA ADHERO®  Weather Resistive Barrier (WRB), mineral wool insulation and Terracotta cladding was applied to the CLT in-factory before being transported to site.

The Auckland City Mission project was a great opportunity for Stevens Lawson Architects to implement a range of new technologies on a multi-storey building being built within a tight space.

The project is currently under construction and includes XLAM CLT solid timber structural panels, mineral wool external insulation and a Terracotta rainscreen cladding, with a level of prefabrication to minimise time on site. The building will become a landmark once completed and a real asset for the city by providing safe and comfortable long-term housing for Auckland’s homeless population.

Protecting the CLT from external moisture is key to ensuring its durability and structural integrity into the future. To ensure the whole assembly was kept dry from the start, cladding contractors Symonite chose to pre-apply pro clima SOLITEX EXTASANA ADHERO®  Weather Resistive Barrier (WRB), mineral wool insulation and Terracotta cladding system to the CLT in factory before being transported to site.

pro clima SOLITEX EXTASANA ADHERO® (or just ADHERO for short!) is a BRANZ Appraised self-adhesive Weather Resistive Barrier (known as a wall and roof underlay), which consists of a non-porous thermoplastic membrane (TEEE) protected by a layer of UV stable fleece. The product has 10,000mm water column resistance and is airtight yet highly vapour permeable. When installed to a solid substrate such as CLT, pro clima SOLITEX EXTSANA ADHERO®  offers a high level of resistance against the elements and can be left exposed to UV light for up to 180 days.

On the City Mission project, the joints between the CLT panels were sealed with pro TESCON EXTORA® flashing tape in situ, and all screw penetrations made by the cladding brackets and insulation pins were sealed with pro clima TESCON® NAIDECK  butyl sealing strip to maintain the integrity of the membrane. pro clima TESCON EXTOSEAL®, a stretchable one piece sill tape, was applied to windows openings as per E2/AS1, which makes it an easy solution for any builder to install.

Once protected from long-term UV exposure, pro clima SOLITEX EXTASANA ADHERO® and the system products remain functional for the life of the cladding itself, ensuring the building is an asset to the Auckland region for many years to come.
