Take a closer look at this product with these additional images.

“A really heavy duty, robust membrane for ensuring breathability whilst limiting flame spread, without the concern of UV damage to the fabric beneath” – Chris Brookman

 

Product overview.

Where is it used?

  • Ampatop B Black can be used on all vertical facades where no more than 30% of the surface between cladding strips or modules is open.
  • It can be used on closed facades or on roof structures, over wood fibre insulation or directly on to timber studs/rafters.

How much will I need?

  • Each roll of Ampatop B Black is 50 x 1.5m, or 75m² per roll.
  • Overlaps of 100mm are recommended which reduces the coverage of a roll to 70m²

Can I use it on a roof?

  • Ampatop B Black is suitable for fully tiled/slated roofs but not suitable for use on roofs with gaps between roof covering materials.
  • For roofs down to a pitch of 5° use Ampatop Seal. This product is not designed to be exposed for more than 6 months though so make sure that the roof is covered by this time.

How is it used?

  • Ampatop B black should be laid onto the existing support structure, taut and without any folds, with the black side out- wards.
  • It should be fastened with staples that must be invisible in the overlap area. It is advantageous to cover them with battens.
  • Both the vertical and the horizontal overlaps should be 10cm wide and taped down with Ampacoll UV tape, so that it is windproof.
  • Next the counter battens are laid, thus finally fixing the wind proofing to the support structure.
  • Visible staples that are exposed to the weather could lead to leaks, and as such should be avoided.
  • We recommend fixings that are galvanised as a minimum, with stainless steel being preferable.
  • The counter battens are required to secure further work and prevent any possible weather effects (e. g. wind suction or pressure).
  • Penetrations and connections should be bonded to make them windproof with Ampacoll UV tape.
  • The connection width should, where possible, be at least 10 cm. If this is not possible, a mechanical fixing is advisable.
  • In the case of windows and external doors, Ampatop B black should be made windproof with Ampacoll UV tape on the frame and if necessary secured mechanically.
  • We recommend that the façade cladding is installed as soon as possible. In any event, the cladding must be mounted within 6 months.
  • The joint width may be up to 30 mm. The individual façade elements must be at least twice as wide.
  • The percentage of openings must not exceed 30 %.
