Brush

Home \ Brush

The contoured rectangular brush head is reinforced with carbon fibre. This provides lightness strength and the necessary rigidity without equal. It is filled with solid  foam to provide further strength and rigidity in addition to thermal and acoustic insulation.

It allows a handle angulation up to 25 degrees.

The rigid sole of the brush and the connector (joint and stud) are made from elastomeric polymer.

A cylindrical broomstick in carbon fibre has been developed specifically to improve overall balance.

Frequently Asked Questions

At my curling center, studying the quality of the water used to irrigate the surface of the ice and the deposit of the droplets, I noticed that the water had excellent quality. However, the dirt accumulating little by little into the top surface of the ice was coming from fabric fibres, plastic residues, hair, rubber, dust etc… From these observations came the idea to make and try a brush with a flat and rigid sole. A sole made of a synthetic material, resistant to degradation, non absorbent, much more efficient, easy to clean, more ecological and requiring much less energy in its use.

It is difficult to understand, especially after 30 years utilizing a fabric made not specifically for this particular use, requiring a large amount of energy in its use and requiring frequent replacement! Manufacturers worked at adapting different types of support to the fabric sole without significantly improving the most important part of the brush to properly level the droplet heads.

The rigid sole is made of a polymer elastomer, a material extremely resistant to wear, a water lubricant, having a controllable elasticity and hardness, also being able to recover its shape if deformed. When attached to the head of the brush, the sole is very flat and rigid. The flat surface has a grooved pattern to adjust the friction surface and to trap frost and dirt.

As the great majority of materials, including wood and plastics, were too heavy, we have used a more ideal solution; the use of modern composite materials of high technology, such as the highly rigid carbon fibre which is very light in weight.
This makes it the first lightweight and ultra-rigid curling head brush in carbon fibre.

The cushioned sole that is covered with fabric sinks on the droplets. It lowers all the droplets of different heights equally and keeps an uneven surface of ice.
The flat and rigid sole cannot sink on the droplets; it levels the highest heads to bring them down to the same level. It therefore allows the stone to slide more freely and accurately on its path.

The sole fabric of nylon yarn (itself hydrophilic) absorbs the melted water in its mesh and reduces little by little the droplets. On the contrary, a rigid sole allows melted water to refreeze after its passage, is not absorbent and allows the droplets to maintain the proper height during a game.

As this sole touches only the top of the highest droplets, the friction resistance is much lower because it concentrates on small surfaces. This is in fact a very effective brushing technique considering the reduced effort required.

It is very different! The first test gave the impression that the rigid sole is too easy a glide. However in a short time the « feeling » is much better than with other types of brushes.

The material used for the manufacturing of the sole is almost indestructible. High resistance to abrasion, wear and tear are important physical properties of the sole material. The sole never needs to be replaced during a game.

The sole does not absorb water and it cleans easily between each use, thus maintaining the same efficiency throughout the whole game. Players who use the rigid sole brush claim it will bring the stone a few feet farther when necessary. Saved energy ensures a better efficacy of brushing until the end of the game. Older players can expect to enjoy their sport longer while also providing effective brushing. It establishes a better balance in the efficacy of brushing for players with different capabilities.

An ultra-light carbon fibre broomstick. For this purpose, a broomstick specifically adapted to the ultra-light brush head is designed to be attached without screws (avoiding the cracking of the end of the handle) with shock-absorbing rubber on the stud of the universal connector.
This one size (27 mm) broomstick accommodates all hand sizes very well.

Slightly more expensive than the fabric brush, but taking into account the sustainability of the sole, it becomes more cost effective over time.
