Protect wet areas with GIB Aqualine®. New Zealand's No 1 wet area lining.
Steam and moisture damage in wet area rooms can be disastrous, expensive and time consuming to repair. That’s why more specifiers and builders use GIB Aqualine® in bathrooms, laundries and kitchens that any other linings.* They know that its water resistant core containing special polymers to help prevent moisture penetration is the best insurance against future liability and expensive call-backs. What’s more, the performance of GIB Aqualine® is independently verified by BRANZ Appraisal.
Over 70% of the New Zealand building industry uses GIB Aqualine® as a tiling substrate in bathrooms*. Its fibreglass core gives added strength that easily supports the weight of tiles to provide a solid, stable backing. Plus its outstanding dimensional stability means it will not move with changes in moisture.
WATER ABSORPTION TEST: These photographs show what happens when GIB Aqualine® (green surface paper) and GIB® Standard plasterboard (white surface paper) are soaked in coloured water for two hours. The core of the standard plasterboard has absorbed the water, while the core of GIB Aqualine® is relatively unaffected.
