Frequently Asked Questions

Listed on this page are answers to common questions. If you do not see the answer you are looking for contact us.

Are there any environmental influences that have an impact on the sealing?

To get an optimal sealing result the humidity should be below 40%. If the humidity is higher, the intake air should be heated.

What needs to be observed when sealing inside a building or room?

When sealing in a building or room all smoke and fire alarms as well as sprinkler systems should be switched off in advance cause the sealing process can activate those.

How big can one individual hole be?

When sealing with AEROSEAL an individual leakage can have a maximum diameter of 1,5 centimetres. For larger leakages it's not guaranteed that the leakage will be sealed completely. Bigger surfaces can be sealed manually.

Which components should be removed prior to the sealing process?

Before sealing with AEROSEAL components like sensors or differential pressure sensors as well as other components which are used for measurement should be removed cause the functionality could be influenced by the sealing process.

Components like volume and fire dampers can remain in the duct system. Just make sure that they are completely open so the sealant can get through.
The cured sealant is completely odourless and will withstand temperatures from -29C to +249C.
