Sirio P

Plastomeric polymer-bitumen waterproofing membrane, reinforced with rot-proof non-woven polyester fabric stabilised with fibre glass mat.

Sirio/P is manufactured from distilled bitumen with special elastomeric and plastomeric polymers added to obtain a phase inversion compound. This continuous phase is formed by polymers in which the bitumen is dispersed. The performance of the membrane is therefore increased along with durability and resistance to high and low temperatures by these polymers. Sirio/P is produced with a reinforced rot-proof “non woven” polyester fabric composite stabilised with fibreglass mat, offering dimensional stability in hot conditions and reduces the problem of banana effect and retraction of lap joints. Sirio/P has the upper face self-protected with hot bonded and pressed slate granules, except for an over-lapping side strip. The underside is coated with Flamina. This plastic film melts when torched and is embossed to obtain the pretension required and allow optimal retraction of the film. This allows the installer to torch a greater surface area for faster and more reliable installation.

USES

Sirio/P has been specifically designed for the waterproofing of flat or sloped roofs, usually as the cap layer in a multilayer system. Sirio/P is only available in Mineral finish and is designed for maintenance traffic only.

ADVANTAGES

  • Uniform thickness – eliminating likelihood of uneven application possible with liquid applied membranes
  • Polyester fabric composite reinforcement ensures dimensional stability and high strength while maintaining flexibility during application and service
  • Over laps are heat fused providing a homogenous joint, eliminating water ingress beneath the membrane
  • Long lasting strength, elasticity and stability make Sirio/P ideal for use as a waterproofing membrane system in new buildings or refurbishment
