Preformed 600Pa Expanding Foam Tape

Q: What is expanding foam tape used for?

FL4513 Expanding Foam Tape is designed to create a reliable seal against water, vapour, air, sound and dust. It is suitable for use in expansion and contraction joints, as well as static gasket-type joints such as window sills and mechanically fastened joints.

Q: Where can FL4513 Expanding Foam Tape be used?

FL4513 is ideal for sealing expansion joints, contraction joints, window sills and mechanically fastened joints. It expands after installation to fill gaps and create an effective long-lasting seal.

Q: Is FL4513 waterproof?

FL4513 provides heavy rain resistance of 600 Pa, making it suitable for sealing joints exposed to wet weather conditions. It is designed to help prevent water penetration while also sealing against air, vapour and dust.

Q: Does FL4513 provide sound insulation?

Yes. FL4513 offers noise insulation of up to 42 dB with a single sealing tape and up to 59 dB when two sealing tapes are used without a heat-insulating layer.

Q: What temperature can FL4513 withstand?

FL4513 has a service temperature range of -30°C to +100°C, with short-term resistance up to 130°C. This makes it suitable for a wide range of indoor and outdoor sealing applications.

Q: What is FL4513 made from?

FL4513 is manufactured from resilient open-cell polyurethane expanding foam impregnated with a water-based acrylic-modified asphalt emulsion. As the foam expands, it creates continuous pressure against the joint surfaces to form a secure seal.

Q: Does FL4513 meet any recognised standards?

Yes. FL4513 is approved to DIN 18542:2009 and is classified as B1 under DIN 4102-1 and Class E under EN 13501 for fire behaviour.

Q: Is FL4513 resistant to alkaline materials?

Yes. FL4513 is resistant to alkaline media, making it suitable for a variety of construction and building applications.

Q: How should FL4513 be applied?

Before application, ensure all surfaces are clean, dry and free from grease, dust and loose material. Proper surface preparation helps achieve the best sealing performance.

Q: How should FL4513 be stored?

FL4513 has a storage life of 24 months from the date of production when stored correctly.

Preformed 600Pa Expanding Foam Tape provides a reliable, weather-resistant seal for movement joints around windows, doors and façade systems. The pre-compressed foam expands after installation to create an airtight and watertight seal while accommodating joint movement.

Product Information

Preformed 600Pa Expanding Foam Tape is a pre-compressed polyurethane foam sealing tape designed to create durable, weather-resistant seals around windows, doors and façade systems. After installation, the tape gradually expands to fill the joint, helping to create an airtight and watertight seal while accommodating natural building movement.

Suitable for a wide range of construction applications, the tape helps protect joints against wind-driven rain, draughts, dust and noise. At the same time, its vapour-permeable design allows moisture to escape from the joint, helping to support long-term building performance.

The preformed design makes installation quick and straightforward. Simply apply the tape to the frame or substrate before installation. As the foam expands, it fills irregular gaps and provides a consistent seal without the need for additional sealants in many applications.

Tested to 600Pa for driving rain resistance, this expanding foam tape is ideal for sealing movement joints where reliable weather protection and flexibility are essential.

Whether you’re installing windows, doors or curtain wall systems, Flowstrip Preformed 600Pa Expanding Foam Tape delivers dependable sealing performance for both new build and refurbishment projects.

Instructions & Safety

Before applying the tape, make sure all surfaces are clean, dry and free from grease, dust and loose material.

Next, choose the correct tape size for the joint so the foam can expand fully.

Then apply the tape to one side of the joint and allow it to expand naturally until it fills the gap.

For the best results, store the product in a cool, dry place away from direct sunlight. When stored correctly, FL4513 has a shelf life of up to 24 months.

Before using the product on a new application, carry out a suitability test. Finally, follow normal site safety procedures and refer to the Safety Data Sheet (SDS) for full handling guidance.
