Paraflex System

Paraflex ARD/S and ARD/HS are SBS modified bitumen polymer waterproofing membranes intended for all waterproofing applications including; Flat Roofs, Terraces, Podiums, Car Parks and Bridge Decks, Tunnels, Foundations and Underground Structures.

The Paraflex range of waterproofing membranes is FM approved, may be used in new build and refurbishment applications and are suitable for applications in low temperature conditions. Paraflex remains flexible at low temperatures and exhibits high resistance to thermal stress.

Reinforced Bituminous Membrane (RBM) which is commonly referred to as felt, still remains one of the most widely specified and installed forms of flat roof waterproofing for both new build and refurbishment projects across many market sectors within flat roofing.

There is a broad range of polymer modified felts to choose from to suit different applications.

RBM can accommodate extreme stresses from thermal movement and wind loading, whilst withstanding a higher degree of construction and maintenance traffic, making it an ideal choice for many projects.

Combining bitumen with additives Styrene Butadiene Styrene (SBS) alters the characteristics and performance of the membrane.

The addition of different carriers such as glass fibres, polyester or a blend of both produces a waterproof material on a roll that is easy to install, very strong, and low in cost.

Many developments and improvements have been made over the years, including development of both the bitumen compound, modification of polymers and the reinforcement materials used, originating with materials such as tar paper or asbestos, progressing to safer, higher-quality materials such as glass fibre or more recently polyester.

Polyester is probably one of the biggest improvements for RBM, making membranes extremely resilient, durable and long lasting. Improving the resistance to tearing and impact along with its resistance to withstand foot traffic.

The Paraflex SBS bitumen compound’s special formulation ensures high mechanical performance, cold flexibility at temperatures down to -25°C and excellent fatigue strength. The membrane is manufactured with a mineral slate or mineral stone granule coating to the upper surface of the membrane, in various colours, offering UV protection and slip resistance. The lower face is coated with Termotene® fusible film which aids unrolling and facilitates torch bonding to various substrates.
