EISEDICHT HOTSchott Tyvek® Heat-Resistant Pipe Grommets – 100–165 mm, up to 250 °C

EISEDICHT HOTSchott Tyvek® heat-resistant pipe sealing grommets are designed for airtight sealing of penetrations where high-temperature pipes pass through airtight or windtight building layers. The HOTSchott system uses a specially heat-resistant flexible sleeve and is suitable for pipe temperatures up to 250 °C.

The grommets are particularly intended for penetrations such as flue and exhaust pipes, where sealing materials require increased temperature resistance. The HOTSchott system has been tested by TÜV Süd and is designed to allow durable sealing directly around heat-conducting pipes.

Each variant uses a flexible 60 mm high heat-resistant sleeve with integrated strain relief. The permanently elastic sleeve accommodates construction-related movement while maintaining the seal around the pipe.

The self-adhesive and tear-resistant Tyvek® adhesive collar provides a reliable connection to the airtight layer. The collar uses an extremely strong polyacrylate adhesive and has a specified temperature resistance from -30 °C to +100 °C.

The grommets are suitable for indoor and outdoor applications, are UV-resistant and halogen-free, and can be installed from +5 °C.

The supplied product information states compliance with DIN 4108-7 and DIN 18015-5. The HOTSchott system is also specified as tested for flue gas systems according to DIN 14241-1 and DIN 13216-1, and as meeting GEG 2020 airtightness requirements.

Applications & Usage

The EISEDICHT HOTSchott heat-resistant pipe grommets are intended for sealing high-temperature pipe penetrations through airtight and windtight layers such as vapour barriers and vapour control layers.

Typical applications include:

• Flue pipe penetrations

• Exhaust pipe penetrations

• High-temperature technical pipework

• Airtight and windtight roof or wall penetrations

• Pipe penetrations in vapour barriers and vapour control layers

An opening corresponding to the pipe diameter should be created in the membrane. The correctly sized HOTSchott grommet is then bonded according to the manufacturer's installation instructions.

The flexible heat-resistant sleeve seals directly around the pipe and accommodates movement, while the adhesive collar provides the connection to the surrounding airtight layer.
