EPP ducting is an alternative to insulated steel ducts or insulating ventilation ducts
with one's own hands using mineral wool or rubber foam. Ducts and fittings made of EPP
(expanded polypropylene) are a ready solution for heat recovery installation.
Dedicated for installation in the outdoor and exhaust ductwork section.
Although expanded polypropylene "looks like" ordinary polystyrene, it is a stronger
material, meaning that EPP is both lightweight and durable, and has excellent
thermal insulation properties, which means EPP pipes do not need to be insulated.
EPP ducts come in two thicknesses: 15mm and 43mm.
