Insulated aluminium profile is a composite building material made of an aluminium profile filled with plastic insulation that provides heat and sound insulation. It has 40-70% lower thermal conductivity than normal aluminium profiles. In addition to insulation, it has good airtightness, waterproofing, fire resistance, security and easy maintenance due to its aluminum and plastic construction. Its insulation and soundproofing properties make it suitable for construction near highways to block traffic noise transmission.
