Firestop pillows are passive fire protection items used for firestopping holes to achieve fireproofing. The various kinds of firestop pillows are intended to slow the spread of fire. They are often used to meet fire-resistance ratings in conduits that need frequent access.

Description and use
Firestop pillows are used for firestopping holes in wall or floor assemblies, particularly in openings that require frequent access (e.g., cable changes), requiring the removal of the firestopping and resealing after the changes are completed. The products are required to have fire-resistance ratings and to be used in accordance with a certification listing.

There are three types of firestop pillows:[citation needed]

rockwool batts with intumescent resin inside plastic bags
vermiculite with intumescent graphite inside of fibreglass bags
intumescent foam rubber
The intumescent resins in batt-based firestop pillows contains hydrates, or chemically bound water. On the fire side, the plastic bag burns off exposing the intumescent to the fire, which releases the water in the form of vapour or steam. The steam rises and hits the plastic bag interior on the unexposed side, where it condenses back to water, and runs back down to cool the installation below. Batt-based pillows are held in place by compressing them, allowing friction to restrain them.

The vermiculite fabric bag and the graphite are noncombustible. There is also no significant release of chemically bound water.

The foam-based pillows intumesce, swelling as a result of heat exposure.</think>

French Open

The trophies have been awarded to the winners since 1953 and are manufactured by Mellerio dits Meller, a famous Parisian jewelry house. They are all made of pure silver with finely etched decorations on their side. Each new singles winner gets his or her name written on the base of the trophy. Winners receive custom-made pure silver replicas of the trophies they have won. They are usually presented by the President of the French Tennis Federation (FFT).

The trophy awarded to the winner of the men's singles is called the Coupe des Mousquetaires (The Musketeers' Cup). It is named in honor of the "Four Musketeers". The trophy weighs 14 kg, is 40 cm high and 19 cm wide. The current design was created in 1981 by the Mellerio dit Meller. Each winner gets a smaller-size replica and the original remains property of the FFT at all times.

The trophy awarded to the winner of the women's singles is called the Coupe Suzanne Lenglen (Suzanne Lenglen Cup) since 1979. The current cup was awarded for the first time in 1986. It is, with a few details, a replica of a cup offered at the time by the city of Nice to Suzanne Lenglen. This trophy, donated by Suzanne Lenglen's family to the Musée National du Sport, was awarded between 1979 and 1985 to every winner until the FFT made a copy. Each winner receives a smaller-size replica and the original remains property of the FFT at all times.</think>
