DURABLE AND SECURE RIDGE AND HIP VENTILATION.
- High-quality Aluminium
- High ventilation shaft
- High butyl adhesive application over the entire surface in the bead - for optimum adhesion and seal
- Easy processing
CASA-Alu is a ridge and hip roll made of solid metal and it has excellent ventilation properties.
The air permeability is around 200 cm2/m in accordance with DIN 4108, part 3. The material is 0.15 mm thick. The high application of butyl adhesive – also in the corrugation valleys – provides a durable, tight barrier against moisture. CASA-Alu can be easily centrally fixed on the ridge batten using the attached longitudinal beads.
The ridge and hip role is suitable for a wide range of roofing materials:
Clay tiles, concrete roof slabs, slates, scalloped tiles, fibre cement panels.
