HDPE Fresh Air Corrugated Pipe with Aluminum Foil Insulation — Acoustic Insulated Ducting for Residential MVHR

This pre-insulated HDPE fresh air corrugated pipe combines a white HDPE double-wall corrugated core with a sound-absorbing cotton layer and an outer aluminium foil insulation jacket. The construction does two jobs at once: it keeps supply air temperature stable through unheated voids, and it suppresses fan and airflow noise along the run. It is the usual branch piping choice for wall-mounted and ceiling-concealed heat recovery ventilation (MVHR) systems in apartments and villas.

Key Features

Three-layer construction — HDPE corrugated core + acoustic cotton + aluminium foil composite skin
Anti-condensation — the foil jacket limits surface sweating on cold supply runs in humid climates
Noise reduction — the sound-absorbing interlayer dampens fan hum and turbulence noise
Flexible routing — bends by hand around beams and corners, sharply reducing the number of joints
Push-fit compatible — the same quick-connect interface as our uninsulated HDPE pipe family

Typical Applications

Insulated branch runs from the MVHR unit to the air distribution box
Ceiling-void routing above kitchens, bathrooms and corridors in apartments
Villas and hotels where supply ducting passes through unconditioned spaces
Retrofit projects where condensation and noise are the two main complaints

System Matching

Pair this insulated pipe with our pre-insulated HDPE semi-rigid radial ducting, ABS air distribution boxes, quick-connect tees and round ceiling diffusers to build a complete concealed fresh air system.

FAQ

Q: Can it be embedded in screed or concrete?
A: This pipe is intended for open routing in ceilings and service voids. For screed-embedded underfloor runs use our insulated flat duct series instead.

Q: Is the aluminium foil jacket suitable for humid climates?
A: Yes. The foil layer acts as a vapour barrier, which is exactly what prevents surface condensation in humid regions.

Q: What is the MOQ and lead time?
A: We hold regular stock across common diameters. Contact our sales team for current stock levels, wholesale pricing and lead time for your market.
