No expansion joint material is required during installation.

FLEX is a safe choice for your health approved by National Institute of Public Health.

Non-recycled material

Nest Flex heat and noise insulation

Insulated ducts

We offer you the option to use Nest Flex in uninsulated roof frame.

Standardly we recommend a 500mm variant (⌀504mm out) but based on different requirements of your construction, a 250mm (⌀254mm out) variant is available too.

We use a cotton of a great quality and density.

Using an insulation allows you to use our ducts in:

✔️  air conditioning

✔️  air heating

✔️  commercial use with fluctuating temperature

✔️  places with fluctuating temperature (roof frame, etc)

For saving time and effort order a completely pre-insulated duct for a supplementary charge as a part of our premium service.
