Fire-rated UV resistant facade membrane – Ampatop RF Black

Product overview

Where is it used?

• Ampatop RF Black can be used on all vertical facades where no more than 40% 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 is it used?

• Ampatop RF black should be laid onto the existing support structure, taut and without any folds, with the black side outwards.
• 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 Flexx 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 RF black should be made windproof with Ampacoll UV Flexx 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 50 mm. The individual façade elements must be at least twice as wide.
• The percentage of openings must not exceed 40 %.

How much will you need?

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