Wavin Ventiza m-over sleeve PVC round 125 mm SN4

An M-over sleeve is often used at an expansion joint to accommodate movements caused by expansion and contraction in building materials. The over sleeve provides a flexible and airtight connection between two pieces of duct, while allowing them to move slightly relative to each other.

Main Features

• Flexibility: The sleeve can accommodate longitudinal movements (expansion and contraction).
• Ease of Installation: Typically slid over the pipes and connected with a rubber ring.

The oval ducts and fittings have a built-in height of only 135 mm (duct height 125 mm). This makes the system suitable not only for recessed applications but also for installation in lowered ceilings or other space constraints. The robust impact-resistant PVC makes them durable and resistant to loads during concrete pouring.

Recessed ducts are ventilation ducts integrated into a floor or concrete to enable air distribution or extraction in buildings. These flexible products are designed to be invisible and are commonly used in new construction and renovation projects. Furthermore, a recessed duct can be used in walls, floors, and/or ceilings. Combined with a straight recessed duct and various fittings, a ventilation duct can be installed as desired. There are both round and rectangular recessed ducts. Some advantages of recessed ducts include: efficient airflow, space-saving, noise reduction, and design flexibility.

Ducts and Fittings: Airtightness and Durability

The ducts and fittings meet the highest airtightness class, ATC1, as established in NEN-EN 17192:2019. This means that the system is three times more airtight than systems with ATC2, which corresponds to the LUKA airtightness class D. This high airtightness improves both energy efficiency and air quality.

Benefits of Low Wall Roughness

Thanks to the low wall roughness of PVC, there is less dirt deposition and friction losses are minimal. PVC has the lowest wall roughness of all ventilation ducts, contributing to optimal airflow. Flexible ducts, on the other hand, have the highest wall roughness, although they excel in flexibility.

Strong and Reliable Connections

A unique feature of the system is the presence of additional ribs around the glue sleeve. These ribs enhance grip and provide a stronger connection, which is essential during concrete pouring.

Durable and Easy to Install

The ducts are 100% recyclable, contributing to environmentally friendly construction solutions. The use of adhesive connections makes installation quick and easy, saving both time and costs.
