Bituminous SBS modified capsheet reinforced with a non-woven polyester felt. The upper surface is finished with mineral chippings. The underside has a quick-melt thermofusible film. Designed for torch-applied applications and Safe2Torch details using hot-air.

Scope

  • Waterproofing under tiles on pitched roofs, both for its thickness and its mechanical resistance.
  • Capsheet in multi-layer roof waterproofing systems with mineral self-protection.
  • Capsheet in single-layer waterproofing systems.

Advantages & Benefits

  • High resistance to static and dynamic piercing.
  • Self-healing and rot-proof.
  • The mineral finish gives the membrane UV resistance.
  • High tensile strength and high elongation at break.
  • High resistance to tearing.
  • Total impermeability to water and water vapour.
  • Very stable in the long term.
  • Allows for adaptation to any type of geometry.

Support

  • Old bitumen membranes.
  • Compatible thermal insulation products.
  • Concrete subsrates.
  • Mortar subsrates.

Instruction for Use

Preparation of the substrate:
-The surface of the base substrate shall be resistant, uniform, smooth, clean, dry and free of foreign bodies. In the case of thermal insulation, the boards shall be laid in a grid and with no gaps between boards greater than 0.5 cm.
  • Top layer of multi-layer membranes with mineral self-protection. The sheet is laid in the same direction as the bottom sheet, with the overlap line offset by approximately half of the roll. The sheet is fully welded to the bottom sheet with a blowtorch. The overlaps are to be welded and are 8±1 cm in the longitudinal direction and 10±1 cm in the transverse direction. To join the transverse overlap at the ends of the rolls, it is necessary to heat the transverse edge of the lower sheet in a 10 cm strip, eliminating or embedding the protection aggregate in the bituminous mass and then weld the end of the following piece.
  • Self-protected single-layer membrane, adhered system. The adhesion of the membrane to the substrate is done with a blowtorch. In the case of mortar or concrete substrates, a bituminous primer (CuridĂ¡n, ImpridĂ¡n 100, MaxdĂ¡n or MaxdĂ¡n Caucho) must be applied beforehand. If the substrate is a weldable thermal insulation board, i.e. asphalt-finished (RocdĂ¡n A or RocdĂ¡n PIR VA), the primer is not necessary. The overlaps are to be welded and shall be 8±1 cm in the longitudinal direction and 10±1 cm in the transverse direction. To join the transversal overlap at the ends of the rolls, it is necessary to previously heat the transversal edge of the lower sheet in a strip of 10 cm, eliminating or embedding the protection aggregate in the bituminous mass and then weld the end of the following piece.
  • Waterproofing under tiles on pitched roofs. Proceed as described above, but mechanically fasten the overlaps.

Indications and Important Recommendations

  • In case of new construction and renovation, possible chemical incompatibilities with APP plastomer-modified bitumen sheets shall be taken into account.
  • In case of refurbishment, chemical incompatibilities with old waterproofing systems consisting of PVC membranes, modified tar-based mastics or any other, shall be taken into account, and it may be necessary to remove them completely or to use suitable separating layers.
  • If it is necessary to adhere to metallic or slightly porous elements, a bituminous primer (IMPRIDAN 100) shall be applied to the entire surface to be welded beforehand.
  • On exposed self-protected roofs, occasional water retention that could lead to sediment accumulation and damage to the waterproofing membrane shall be avoided.
  • This product may form part of a waterproofing system, so all the documents referred to in the Danosa Solutions Manual must be taken into account, as well as all the regulations and legislation that must be complied with in this respect.
  • Self-protected sheets finished in light colours perform better thermally.
  • Self-protected sheets in coloured mineral or ceramic granules may have different colour shades depending on the different production batches. The mineral granule may darken naturally over time.
  • Not suitable as cap sheet on green roofs; use GARDEN variant.
  • Possible incompatibility between thermal insulation and waterproofing shall be checked.
  • Special attention must be paid to the execution of the singular points, such as parapets (meetings with vertical and emergent elements), drains, expansion joints, etc.
  • Polyurethane foam shall not be sprayed directly on top of the waterproofing without the use of a suitable separating layer (geotextiles, mortar layers, polyethylene film, etc).
  • If expansion that could affect the sheet is expected, a geotextile separating layer (Danofelt PY 200) shall be used between the sheet and the extruded polystyrene insulation panels, so that each product expands independently.
  • NOTE: For more information on the Danosa systems in which this product is used, please see the document "Waterproofing Solutions".
