J11v

The most frequently sold Jacobi-Walther roof tile is now even better. With the aid of the 32 mm adjustment range in the cover length and the newly developed, high sliding ability in the cover width of up to 8 mm, it provides strong values for new and renovated buildings. Our smooth, fine surface quality from Bilshausen, combined with the impressive choice of sample colours delights developers.
Select your flat roof tile in your desired colour from a total of 17 different, bright colours from standard natural red to high-quality avant-garde glazing. Optimal side folds paired with the high security of the four-tile corner produced with the new J11v will delight you.
