BARRIER NET SD40
The BARRIER NET SD40 vapour barrier is made of polyethylene, a material that strongly restricts the passage of vapour from the hot part to the cold part of the structure, limiting condensation problems. Thanks to its composition, it is not affected by mechanical stress or by staples and nails.
Description
BARRIER NET SD40, the vapour barrier with SD 40 m value.
The BARRIER NET SD40 vapour barrier is transparent, for a simple, fast and safe installation. The reinforcing grid offers great resistance to the membrane, even in the event of pressure caused by the insulating material being blown, which could give rise to mechanical stresses that the reinforcing grid can compensate for; in this way, the membrane is always installed safely.

Description
The application surface must be dry, free of dust and grease. Surface elements must be removed so that the membrane is not damaged during application.
Once applied, the product allows for easy visibility of powder tracer markings and underlying mounting holes.
The membrane is made of a reinforcement mesh that provides excellent resistance, even under pressure caused by the blown-in insulation, which may generate mechanical stress.
Recommended use: This product is intended for installation on the interior side of the building envelope and is guaranteed to withstand only indirect UV exposure for a maximum duration of 2 weeks.
Installation: Unroll the membrane and seal using tape such as: FLEXY BAND, SPEEDY BAND or EASY BAND.
Ensure that the overlap between the membranes is at least 15 cm to achieve an optimal seal.
To ensure correct and professional installation, the use of a nail sealing point is required.
Further details regarding installation can be found in the specific instructions provided by the supplier.
