CE ETA Label for PFP Acrylic

Designed to prevent the spread of fire and smoke through joints and openings in fire rated walls and floors (including openings formed around building service penetrations); the Astro PFP FR Acrylic will also maintain the acoustic design performance.

When subjected to atmospheric conditions, the sealant cures however, it will retain a degree of elasticity for joint movement. Under fire exposure, The Astro PFP FR Acrylic creates a robust fire seal by the formation of a durable intumescent char.

The Astro PFP FR Acrylic can be used with a suitable filling material i.e. stone wool or Astro PFP FR backing material in order to secure correct width to depth ratio, and to reduce the shrinking of the sealant during curing. Minimum depth and maximum width of the joints are included in the installation instructions.

When testing pipes, one can choose not to cap (or close) the pipe, or cap the pipe inside the furnace, or outside the furnace, or on both sides. The configuration chosen depends on the intended application of the pipe and/or the installation environment.

The code defining if a pipe is capped is stated after the fire classification. For instance, EI 60 C/U which means the pipe was capped inside the furnace, and uncapped outside the furnace. The test configuration defines the approvals possible.

Our engineering judgment based on EN 1366-3:2009 are:

Intended use of pipe Pipe end condition 4)
Rainwater pipe, plastic At drainage U/U 1)
Not at drainage C/C 2)
Drainage or sewage pipe, plastic Ventilated drain U/U 1)
Unventilated drain U/C 1)
Drain w/water trap U/C 1)
Not at drainage C/C 2)
Pipe in closed circuit (water, gas, air, electricity etc.) C/C 2)3)
Flue gas recovery system pipe, plastic U/C 1)
Pipe with open ends and ≥ 50cm length on both sides, plastic U/U 2)
Pipe supported by suspension system, metal Fire rated support C/U 1)
Non-fire rated U/C 1)
Waste disposal shaft pipe, metal U/C 1)

1) Suggested in EN 1366-3:2009. 2) Astroflames's judgment based on tests.
3) Metal pipes should have fire rated support. 4) U/U classified fire seals cover C/U, U/C and C/C. C/U classified fire seals cover U/C and C/C. U/C classified fire seals cover C/C.

We have technical representatives who provide assistance in the selection and specification of the products on this site and should be consulted for exact installation and product suitability. Ensure an early engagement with ourselves, designers, main contractor and specialist installers before any installation. Other trades and/or manufacturers may need to be consulted. For in-depth information, specification and technical advice please call our Head Office on:

All interested parties, designer, specifier, main contractor and specialist installers should provide access to allow the fire stopping seals to be regularly inspected and maintained, as well as records kept of such maintenance at minimum periods of 12 months, as required by the Regulatory Reform Order, and repaired if necessary. Reference should be made to ASFP TGD 17 – Code of Practice for the Installation and Inspection of Fire Stopping.


It is vital that those entrusted to design or install a fire stopping product have the necessary levels of competence to undertake the task professionally and thoroughly. The level of competency required will be commensurate with the expected complexity of the building. All designers must eliminate, reduce or control foreseeable risks that may arise during installation, construction or maintenance when preparing or modifying designs. Clients should ensure that the principal designer and principal contractor carry out their duties under CDM regulations. The ASFP foundation course in passive fire protection provides essential knowledge as part of demonstrating competency and understanding in this key fire protection specialism.
