8.10. Securing for uplift
Products must be fixed as soon as they are placed on the roof or façade to
avoid any uplift due to the action of the wind.
Before interrupting the work, it is necessary to check that all the products are
properly fixed and the bundles are also fixed with some straps to avoid risks of
falling materials.
Direction of installation is important for an easier secure.
8.11. Holes
Pipe penetrations must be properly made in concordance with the design taking
in consideration that:
• Pipes can not transmit forces to the façade
• Reduction of the thermal bridges is a must
• Flashings must be water and air tight
8.12. Design of flashings
Flashings must be defined following some recommendations:
• Flat surface shouldn’t be larger than 250 mm to keep the flatness
• Small slope is recommended to avoid water retention.
• Drip is recommended in any flashing to reduce the dirty on the façade.
