DANOSA SELF-DAN AL PRO - 30m x 1m

• SBS polymer modification for improved elasticity and ageing resistance
• Aluminium foil reinforcement for puncture and foot traffic resistance
• Self-adhesive, easy peel, flame-free application
• Adaptable to complex substrate geometries
• Quick and straightforward installation
• Effective for AVCL and radon gas barrier applications

• AVCL for Roofs & Cold Stores: Functions as an air and vapour control layer to limit moisture ingress and maintain environmental stability.
• Radon Gas Barrier: Can be used as a barrier against radon gas infiltration in construction projects.

Important Recommendations:

• Storage: Keep in a dry, protected location away from rain, sun, heat, and low temperatures.
• Cold Weather Installation: Heat the substrate if uncombustible; avoid membrane temperatures above 50ºC.
• Post-Installation Protection: Protect membrane from UV exposure and physical damage after installation.
• Not Suitable as Waterproofing Layer: This membrane is not intended as a permanent waterproofing solution for flat roofs.
• Priming: Apply a bituminous primer on porous or uneven substrates, and when adhering to metallic or slightly porous elements (IMPRIDAN 100).
• Handling: For ease of installation, cut rolls into manageable sizes; use a roller to improve adhesion.
• Compatibility with Insulation & PU Foam: Do not spray polyurethane foam directly onto the membrane; use suitable separating layers such as geotextiles, mortar layers, or polyethylene film.
• Refurbishment Considerations: Check chemical compatibility with existing waterproofing systems (PVC membranes, modified tar-based mastics, etc.) before installation; use separating layers or remove old membranes if needed.
• Do Not Install Over Thermal Insulation on Roofs: Avoid direct installation over insulation in roofing applications.

Can this membrane be used as a waterproofing layer on flat roofs?

No, this membrane is designed for AVCL and radon barrier applications, not as a permanent waterproofing layer for flat roofs.

How should the membrane be stored before installation?

Store in a dry, protected area away from sun, rain, extreme heat, or low temperatures.

Can it be installed over insulation or with polyurethane foam?

No, a suitable separating layer (geotextiles, mortar layers, or polyethylene film) must be used to avoid chemical incompatibility and allow proper adhesion.
