Thermoduct wall bushing 250 mm

Thermoduct Wall Duct 250mm

This Thermoduct wall duct is suitable for heat recovery ventilation (HRV) systems and other ventilation applications where air is neatly discharged through the façade. The wall duct is constructed from 1 mm aluminium with a welded tube of the same material. Both welding and powder coating are done in-house, ensuring the finish and fit are carefully controlled.

Benefits and Features

• Wall duct made of 1 mm aluminium for a sturdy and durable exterior finish.
• Welded tube of 1 mm aluminium for a secure and robust connection.
• Thermoduct 9 mm insulation with thermal conductivity 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 in black for a neat and wear-resistant finish.
• Suitable for HRV systems and ventilation ducts with a 250 mm connection.

Lightweight, Dimensionally Stable, and Suitable for Outdoor Use

The aluminium construction remains lightweight and dimensionally stable, even after prolonged outdoor use on the building exterior. Since the tube is welded in-house, the wall duct forms one stable unit, simplifying installation and ensuring a reliable result.

Installation, Maintenance, and Applications

The powder-coated finish requires minimal maintenance and provides a clean appearance on the façade. This wall duct is ideal for residential buildings and small commercial projects where a neat, insulated connection through the façade is necessary. It combines a robust aluminium base with practical Thermoduct insulation and a precisely finished black coating, suitable for a reliable and durable connection of ventilation ducts through the façade.
