Uninsulated Flexible Duct
Uninsulated flexible ducts are lightweight, ribbed aluminum air ducts used in HVAC systems. They consist of a single outer layer without any insulation, making them easy to install in tight spaces. These ducts are best suited for short runs, connections, or areas where thermal insulation and soundproofing are not required.

Floduct PRE-Insulated Ducting System

Floduct Pre-Insulated Ducting System is a lightweight, high-performance air distribution solution designed for HVAC applications. It features a rigid PIR (polyisocyanurate) foam core factory-laminated with aluminum foil on both sides, providing excellent thermal insulation, airtightness, and moisture resistance. This advanced system ensures energy-efficient airflow, reduced heat loss, and quieter operation while being easy to fabricate, install, and maintain. Ideal for commercial, residential, and industrial environments, Floduct combines durability with superior indoor air quality and long-term cost savings.
