Our region is "a tile region". Although there are many alternatives, reliability is the most important factor for us and of course we do a price-performance analysis like any other company. We used ISOLINE many times and we can say with contentment that it is a perfectly performing and reliable product. We were looking for a perfect waterproof material and once that it's applied we don't need to look behind. Its ease in application and the good relations of Onduline dealers salesmen have been also very influential. Briefly ISOLINE is a non problematic, durable, long lasting product with high brand awareness.
