Pro Clima Early-Close-In allows interior work to begin before cladding installation, maintaining speed and safety on site. The system uses SOLITEX EXTASANA® — a single-layer wall underlay providing up to 180 days UV protection.
SOLITEX EXTASANA® Wall Weather Resistive Barrier
A UV-stabilised, tear-resistant wall underlay that protects the building from wind and driving rain, while still allowing the structure to dry through its vapour-permeable, non-porous TEEE* layer.
When installed as part of Pro Clima’s Early-Close-In system, it provides up to 180 days of weather protection.
Early-Close-In System Advantages
✅ Outstanding durability against UV, wind and rain — up to 180 days of exposure.
✅ Seals the building envelope so interior work can begin before cladding installation.
✅ Can be used in NZS 3604 wind zones up to, and including, ‘very high’ without rigid sheathing.
✅ Can be use in NZ 3604 wind zones up to and including ‘extra high’ over rigid sheathing - RAB, SIP.
✅ Tear-resistant synthetic weather resistive barrier designed for long-term durability.
✅ Allows drying - highly vapour permeable (Class 4).
✅ Weathertight - non-porous membrane technology.
✅ Fire retardant.
SOLITEX EXTASANA® can be used as an Early-Close-In wall underlay on timber framed buildings in accordance with Codemark CMZN30032

Installation Guides
Ensure a compliant, weathertight installation. Download the correct guide for your cladding type, along with essential documents for your project records.
Stay Compliant and Informed
Proper documentation is key to a successful sign-off. Use our Certificate of Installation and Minor Variation Statement to formalise your work, and refer to the official brochure for technical data at a glance.
* Early Close In is achieved when wall underlay is installed according to the relevant Early-Close-In Application guide (see above), and all elements and junctions of the building envelope are installed (except cladding) to achieve compliance with NZBC Clause E2.2 ie, installed roofing, windows and doors, window and door seals, flashings, penetration seals. Continuation of internal work is subject to a pre-line inspection. Warranty coverage does not extend to damage or delays caused by weather events deemed force majeure.
