Corrugated pipes are usually used to connect ventilation outlets to the corresponding channels. The length of the outlet is 86 cm, and after installation, the length of the outer part, i.e. the height of the outlet above the roof, is 48 cm.
Installation of ventilation outlets and aerators is performed as follows:
The place where the element to be mounted will be chinese thailand data is covered with ondulin sheets according to the usual scheme, with the exception of the side that faces the ridge.
Next, a special base sheet is placed at the exit site, which has an opening, a mount and a sealing casing for the ventilation outlet or aerator.
An element is installed that must be secured along each wave.
The pass-through element is installed on the laid ondulin sheet with an overlap of 17 cm and is secured with special nails in each wave.
Next, a regular sheet of ondulin is laid on the ridge side so that its lower edge lies on the base sheet with an overlap of 10 cm.
There are situations when it is not possible to use a base sheet with a ready-made opening and a sealing element. Then the opening in the covering is cut out independently, and the gap between its edges and the brought out pipe is sealed using the Enkryl waterproofing system, which is designed to seal problematic joints. It is used as follows:
The area around the opening is treated with a degreasing compound.
Next, the first layer of Enkryl sealant is applied to it and to the pipe brought out into the opening using a brush.
The pipe or aerator is wrapped with reinforcing fabric, for example, viscose Polyflexvlies Roll. Here it is necessary to take a pause - the sealant must soak the fabric well.
The fabric wrap is covered with a second layer of Enkryl, which is also applied with a brush.
This method of sealing the roof passage is designed for 10 years. After this period, the waterproofing will need to be updated.
To seal joints and cracks, instead of fabric and paste sealant, you can use Onduflesh-Super adhesive tape.
