Renovation - Dry roof - Waterproof roof

The SKYDÔME Drain is a system which evacuates humidity found in the roof insulation. It is used in a waterproof membrane where any problem with humidity in the insulation has been identified.


  • The SKYDÔME Drain has been designed to evacuate this humidity and prevent stagnation between the waterproofing and the roof, which also stops the insulation deteriorating and, in the long term, the waterproof membrane being damaged.
  • The solution to water ingress into roof insulation. When the waterproof membrane is pierced (by accident or when it has fallen into disrepair), it reacts like a sponge and soaks up water. It then becomes a thermal conductor and loses all its insulating properties. A simple repair is not enough.
