Installation Video
Protecta FR Graphite is an advanced intumescent sealant engineered to stop the spread of fire, smoke, and toxic gases through service openings in fire-rated walls and floors. It is particularly effective in applications where traditional firestop sealants are insufficient—such as sealing around large plastic pipes and other combustible penetrations.
When exposed to temperatures above 150 °C, the graphite-based formula rapidly expands, closing gaps and maintaining the integrity of the fire barrier. Depending on the specified solution in the installation instructions, FR Graphite can achieve up to 4 hours of documented fire resistance.
Typical Applications
- Sealing around plastic pipes and other combustible services
- Walls and floors with high fire-resistance demands
- Installations requiring significant expansion to ensure a secure seal
FR Graphite is used alongside a suitable backing material to achieve correct joint dimensions and minimise shrinkage during curing. Full installation guidance and verified fire classification documents are provided in the installation instructions.
What types of pipes and cables are approved with FR Graphite?
FR Graphite is tested and approved for:
- Electrical cables and conduits
- Insulated steel pipes
- Insulated copper pipes
- Insulated alupex pipes
- PVC, PE and PP plastic pipes
See installation instructions for details and dimensions.
In which types of constructions has FR Graphite been tested?
Protecta FR Graphite has been fire tested in the following types of constructions:
- Concrete and masonry walls
- Drywall partitions
- Solid timber (CLT) walls
- Floor constructions made of concrete, masonry, and CLT
What fire resistance does Protecta FR Graphite achieve?
From EI 30 to EI 240, depending on the type of service penetration, dimensions, insulation, joint size, and type of construction. For detailed approvals, please refer to the installation guidelines.
Can FR Graphite be used around multiple pipes in one opening?
Generally, only one pipe per opening is allowed. There are exceptions for cable bundles. In timber constructions, there are no minimum spacing requirements between openings, so pipes may be placed side-by-side horizontally in the wall. Always refer to the approved details in the manual.
What is the minimum joint width?
FR Graphite is intended for gaps between 10 and 30 mm. In some cases, openings below 10 mm may be acceptable if depth and backing are sufficient. Note: For plastic pipes, 10 mm is a strict minimum. This is detailed in the approved drawings.
Can FR Graphite be used in damp areas?
No, FR Graphite is intended for dry indoor environments. In areas with high humidity, use Protecta FR IPT Sealant, which is designed for such conditions. Alternatively, paint over the cured joint to protect against moisture.
Protecta FR Graphite has an European Technical Assessment ETA 22/0749 – issued under EU Regulation 305/2011, based on EAD 350454- 00-1104.
FR Graphite is tested according to EN 1366-3, with reference to EN 1363-1.
