Thermoduct wall bushing 125 mm

Thermoduct wall duct 125mm

This Thermoduct wall duct is suitable for HRV (Heat Recovery Ventilation) systems and other ventilation applications where air is neatly discharged through the wall. The wall duct is made from 1 mm aluminium with a welded pipe of the same material. Both welding and powder coating are done in-house, ensuring excellent control over the finish and fit.

Advantages and features

• Wall duct constructed from 1 mm aluminium for a robust and durable external finish.
• Welded pipe of 1 mm aluminium for a solid and sturdy connection.
• Thermoduct 9 mm insulation with thermal conductivity values of 0.039 W/mK at 0°C, 0.045 W/mK at 40°C, and 0.051 W/mK at 90°C.
• Powder-coated black for a neat and wear-resistant finish.
• Suitable for HRV systems and ventilation ducts with a 125 mm connection diameter.

Lightweight, shape-retaining, and suitable for external use

The aluminium construction remains lightweight and dimensionally stable, even with long-term use on the exterior of the building. Because the pipe is welded in-house, the wall duct forms one stable unit, making installation straightforward and the result reliable.

Installation, maintenance and applications

The powder-coated finish requires minimal maintenance and provides a tidy appearance on the façade. This wall duct is used in residential buildings and small commercial projects where a neat, insulated duct penetration through the façade is required. It combines a sturdy aluminium base with practical Thermoduct insulation and a carefully finished black coating, ideal for a dependable and durable connection of ventilation ducts through the wall.
