A sleek Linarte façade finish with vertical lines is timeless. To avoid interrupting the cadence of such a façade in places where a wall louvre or other opening would otherwise provide the necessary ventilation, Renson developed the ventilating BLOCK 25 Flow Linarte profile. It retains the clean appearance of the classic BLOCK 25 but features a ventilation opening in the side of the recessed volume. This recess ensures sufficient air passage to allow natural ventilation without being visible from outside, while the sleek Linarte façade remains intact. The blade combines seamlessly with all other Linarte profiles and finishing options and, in the best Linarte tradition, can be clicked out and replaced individually.
