- Natural weathering period of 3 months: sufficient time for construction phase
- Easy to install and non-slip: for faster work and safe walking during the construction phase
Transparent, full-surface adhesive vapour check and weather protection membrane. Used, for example, to temporarily cover wooden ceilings during the transport, assembly and construction phase or to ensure airtightness on wooden materials and other substrates.

Ampatex Ombrello
Before applying the tape, any pointed or sharp edges and objects such as stones, wood splinters, etc. must be removed. Ensure that the substrate is clean, dry and free of dust, ice and grease. Tip: Install on the construction site with two or three persons. In windy conditions, work with the wind direction. Align Ampatex Ombrello with the markings, imprint or chalkline. Overlap Ampatex Ombrello by at least 10 cm. Note the dashed overlap line for this.
Roll out the membrane so far that it can be aligned. It is best to peel off the narrow cover strip first and thereby fix the membrane in the desired position over the entire length. Then peel off the wide cover strip. While peeling off, rub the membrane well on the surface with a soft broom or similar. Important: Ensure adequate drainage when applying on horizontal or flat components.
Protect the membrane from mechanical damage. Ensure cleanliness on the construction site. Cover exposed areas such as walkways if necessary. Ampatex Ombrello is a temporary weather protection solution and is not intended for flatroof waterproofing. When severe weather with above-average precipitation or hurricane- like wind loads is forecast, it must be additionally secured, e.g. with PVC tarpaulins.
For panel joints and connections, use Ampacoll Flexx pro 150 mm. Penetrations are best sealed with Ampacoll BK 535 (50, 80 or 120 mm). Substrates may have to be pre-treated with Ampacoll Primax or Ampacoll Airmax.
