AEROLL ALU is a technological breakthrough in our range of seals. AEROLL ALU provides optimum ventilation results and an excellent level of protection against rain and snow. AEROLL ALU is suitable for all types of roof tile and all roof gradients. This flexible, ventilated universal seal is easy to lay and handle (it is light in weight and does not take up much space) and comes in rolls of 5 metres (other lengths are available on request) for hips or ridges. Two (wide and thick) Butyl adhesive strips on the underside guarantee perfect airtightness when applied dry, and the seal is suitable for all coverage profiles. Our range was designed to meet series 40.1 and 40.2 UTD requirements, as well as safety standards (preventing the entry of water and/or powder snow, insects, etc.), and offers excellent aeration and ventilation properties for coverings.Traditional product.
