Airtightness products
An airtight home is comfortable and safe to live in. It is also energy efficient and sustainable. Ekovilla has always directed the construction industry towards airtight building and has developed products suitable for this purpose. An Ekovilla air barrier product with the marking X helps you build an airtight home. The X is a sign of airtightness.
Ekovilla X5 air barrier
Ekovilla X5 is a fabric-reinforced air barrier paper for breathable structures. It is used as an internal air barrier, especially with hygroscopic insulations such as cellulose.
Ekovilla X5 air barrier makes easy to build completely airtight buildings ensuring good indoor air quality and energy efficiency.

Properties of Ekovilla X5 air barrier sheet
- allows for a breathable structure ⇒ keeping the indoor air conditions closer to optimum level around the year
- does not prevent the movement of moisture ⇒ capable of drying in both directions
- meets the requirements for air barrier products 5:1 ⇒ reliable structure
- flexible structure ⇒ easy to install in corners
- fabric prevents the rivet from sinking ⇒ construction remains airtight
Installation
Ekovilla X5 is quick and easy to install. It withstands handling without tearing and can be installed even to difficult locations owing to its fabric reinforcement.
The air barrier is fixed by stapling at 200 mm intervals. The joints are overlapped 200 mm or according to construction guidelines and joint durability is ensured by Ekovilla X Sealing tape.
