Exoperm Mono Duro 200 is a fire-rated monolithic breather membrane by Partel, designed to provide exceptional protection against moisture, UV and more. This innovative breathable membrane ensures superior air and moisture control while offering long-lasting UV protection and increased fire resistance. Suitable for both open and closed joint systems, Exoperm Mono Duro 200 enhances building performance and sustainability, making it an ideal choice for modern construction projects. Engineered with advanced PES non-woven fabric and TPU technology, it guarantees durability and compliance with high building standards. Key Features: Monolithic Technology: Exoperm Mono Duro is diffusion permeable polyurethane membrane composed of a 2-Ply sarking, roof underlay and wind barrier using the Next Generation Monolithic TPU functional layer. It extends excellent aging resistance due to Monolithic Technology. This Monolithic TPU layer results in a stronger, more flexible membrane with greater resistance to corrosion and abrasion compared to the micro-porous membranes that are prevalent on the market. More importantly the Monolithic TPU layer creates a complete wind tight, waterproof membrane that actively expels out any water/ humidity unlike most micro-porous membranes that rely on small pores (which have the tendency to block). Fire-Rated: This fire rated breathable mebrane acheives high standard of fire-performance, with a reaction to fire classification of B?s1,d0. It offers superior fire resistance and therfore is deemed suitable for high rise constructions as per current Building Regulations. Highly Breathable: Thanks to its Monolithic design, this breather membtane allows excellent vapour permeability and long term resistance to driving rain Long-Lasting UV Protection: This external breather membrane ensures durability and protection from UV exposure. Energy-Efficient: Designed to improve energy efficiency in buildings. Superior Airtightness: Creates an airtight barrier to enhance insulation performance. Applications: Exoperm Mono Duro 200 fire rated breather membrane is an external breather membrane designed for use on the cold side of insulation on faandccedil;ade wall and roof applications. Membranes are suitable as roofing/decking underlays Some other applications include: Rear ventilated facades, with open or closed joints Timber and steel framed constructions Warm, cold and hybrid roof applications Pitched or flat roofs Sarking boards Installation Guidelines: Breather membranes should be laid should be laid with the printed side facing the installer. Apply onto the existing support structure, parallel to eaves with overlaps of 100mm (4andrdquo;) in a taught manner. It should be nailed or screwed under the overlapped section Tape all joints using suitable breather membrane tapes. Use Nail Seal underneath all battens.
