Cork is the bark of the cork oak, a noble tree with very special characteristics, grown in the Mediterranean region, mainly Portugal. It is a suitable product that has minimal impact on the environment.
Cork has a range of beneficial characteristics, including excellent resistance to oil and anti-vibration properties. Cork is also relatively cheap, but highly effective in sealing a wide range of applications, including electrical transformers and switchgear, fuel and oil pumps. Cork is also commonly used as expansion jointing for flooring. As well as providing Cork sheeting and roll material, using our in-house manufacturing facilities, we can produce Cork strips, gaskets and washers for a wide range of applications.
At CB Frost, we can provide Cork material as sheeting or as roll material, depending on your requirements. Rolls are manufactured 1mtr wide x 10/16mtrs long in thicknesses from 1mm to 6mm and available in a range of grades, Cork sheeting can provide a cost effective solution if you are looking to save funds.
Our cork products come in a wide range of grades, please do not hesitate to contact our Sales team on 0121 773 8494 if you need advice on the most suitable grade for your application.
CBF-2020 (Nitrile/ Neoprene bonded cork)

The History Of Cork
An Early Beginning
Cork has been used for thousands of years in a wide range of applications and civilisations. It has been found in the tombs dating back to ancient Egypt. Ancient Greeks and Romans also made good use of it, with it being used as floats for fishing nets, sandals, wine bottle stoppers and personal flotation devices for fishermen.
Villagers used it to build their homes, as its insulative properties kept them warm in winter and cool in summer. It is also softer than other wood, which made it ideal for flooring as it was comfortable to walk on and was resistant to attack from insects and other pests.
Progression Of Cork
The Romans liked their comforts and they were the kings of innovation from road building, creating coins to buy things with, aqueducts to transport stuff, and public heated baths to wash in. They were also the first civilisation to use pipe insulation for those that carried hot water by wrapping them in cork.
Some time later, a German company developed a method in 1890 for using waste cork. They discovered that combining it with a binding agent allowed it to be rolled into sheets to be cut into whatever shape was desired. This is called agglomerated or compound cork. By using heat and pressure, John Smith discovered that in order to release the naturally occurring resins, he could create a conglomerate of cork particles that didn’t need any binder.
Cork In Automobiles
In the 1960s, all car gaskets were made out of very thin layers of cork. The idea behind any gasket is to provide a seal between two parts of any motor, engine, or other unit. Cork has interesting properties that makes their gaskets provide this seal in a very unique way. Engines have oil inside of them, and as the oil comes up against the cork gasket, it helps to provide the seal. When you first change a cork gasket, the oil will come through the seal a bit until it finalizes the sealing. The oil finishes up the seal when it is absorbed by the cork as it will cause the cork to stretch and create a perfect seal.
