All Duct Insulation

Shop duct insulation products designed to reduce heat transfer and help protect ventilation ductwork against condensation.

Insulating suitable duct runs can be particularly important where ducts travel through cold or unheated spaces, helping maintain air temperature and improve the overall installation.

Frequently Asked Questions

  • What’s the difference between duct insulation and pre-insulated thermal ducting?

    Duct insulation is applied around standard ductwork, whereas thermal ducting has insulation incorporated into the duct system. Both can help reduce unwanted heat transfer and condensation.

  • Can I insulate ventilation ductwork myself?

    It may be possible for a competent DIY installer, but insulation should be continuous and properly sealed. Poor installation can leave cold spots where condensation may still occur.

  • Does duct insulation help reduce ventilation noise?

    Some insulation can provide an acoustic benefit as well as reducing heat transfer, although dedicated duct silencers are usually more effective when reducing fan or airflow noise is the main objective.
