Application

Elastomeric membranes have been developed for use in high-performance built-up systems on flat, pitched or curved roofs; when incorporated in a suitably designed multilayer system they will greatly improve the long-term performance of that system.

Tecnatorch® is intended for use as the capsheet within a bituminous built-up roofing system. The membrane utilizes a special grooved adhesion technology. The self-finished mineral surface provides a decorative and solar reflective finish for the built-up waterproofing system.

Hydrocarbon solvent-based products, such as Naphtha, paraffin and creosote will have a harmful effect and should not be allowed to come in to contact with these membranes.

Description

Tecnatorch® is a torch applied, polyester reinforced, SBS modified bitumen membrane. The polyester carrier is impregnated and then coated in SBS modified bitumen. The upper surface is coated with silica sand and given a 75 mm wide sand-free selvedge for enhanced lap security and is finished with a thermofusible PP film. The underside is given a special grooved profile for torch-on application and is finished with a thermofusible film to prevent adhesion in the roll.

Features and benefits:

  • Durability: Correctly installed and maintained systems incorporating Tecnatorch® cap sheets may be expected to last 20 years.
  • Compatibility: The membrane is compatible with most building materials with which it is likely to come in to contact with during roofing works.
  • Thermal: The material is unaffected by freeze/ thaw cycling. It will support temperatures from -15 to +90 °C without damage.
  • The material is impervious to water.
  • The material is not susceptible to insect attack or pest damage and is unaffected by fungi, moss, lichen, moulds or bacteria.
  • CE marked (BS EN 13707, 13, 0086-CPD-505779).
