“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 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 much will I 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
Can I use it on a roof?
- Ampatop RF 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 3 months though so make sure that the roof is covered by this time.
How is it used?
- Ampatop RF 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 RF 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 50 mm. The individual façade elements must be at least twice as wide.
- The percentage of openings must not exceed 40 %.
