Cork boards allow you to showcase your notes, art and reports. It's easy and quick to post items on a natural cork board. Just tack up your paperwork and decorative materials using thumb tacks or staples, and your material can be re-positioned and removed often and without fuss from bulletin boards. Schools and businesses are able to post and cycle announcements, decorations, lists, and reports easily and frequently. In the home, families can post important "to-dos" and messages. A variety of sizes and designs work for you.
A cork bulletin board display provides a natural acoustic insulation material that is resilient to heavy usage. The cellular structure of this naturally harvested and renewable material has made it the most well-known and efficient insulator for acoustics, heat and mechanical vibration. That's important to ensure all students or meeting attendees can hear and understand everything being presented in the room. Designing your classroom, office, or meeting room with several natural corkboards helps absorb room sounds.
Corkboard displays made from pure grain natural cork are durable and resilient. Cork's unique qualities of flexibility, elasticity and compressibility allow it to recover quickly from push-pin holes pressed within it. In fact, a cubic inch of cork has been shown to withstand a pressure as great as 14,000 lbs without breaking down, and it retained 90% of its original form afterwards. Obviously, a cork board can withstand your heavy use and last an extraordinarily long time.
Classroom acoustics is a major concern and cork boards provide a functional solution. According to educational and acoustic experts, pleasing architectural designs that have been incorporated into many modern schools often make it difficult for students to concentrate.
A natural noise and vibration damper. Hard floors, concrete walls, lots of windows, high ceilings, writing boards, other noises present in schools, as well as school equipment that cause reverberation and distortion or are unable to absorb/dissipate this disruption are causing schools and teachers to find ways to make classrooms quieter so learning can be supported. Placing a natural, unpainted cork board (or several boards) within every classroom offers a significant acoustical benefits while also offering plentiful wall space for displays.
Since their original creation in 1891 to insulate temperature in cold storage areas, cork based boards have evolved to become the silent work-horse in schools and industry whether framed by themselves or designed in combination with a whiteboard, chalkboard, placed on an easel, or covered with decorative fabric.
Where does cork come from?
The evergreen Cork Oak (Quercus Suber L) is grown commercially most favorably in areas bordering the Mediterranean Sea. Portugal and Spain supply approximately 75% of the world's cork. In fact, cork is vital to the economy of the Mediterranean where as many as 80% of people in some areas depend on this crop for their income.
The organic properties of cork have been appreciated for centuries. Thousands of years ago it was already being used as able fishing floats, shoe soles, and bottle stoppers. It began to be utilized for its able display, temperature in the 1890's, and cork acoustic insulation features, whether used as bulletin board displays, wall covering or as flooring, became evident later.
Unlike just about ever other commercial furniture and office product used in schools and businesses whose manufacturing processes often utilize artificial ingredients or processing, cork's advantage is based on its natural features and its' renewable harvesting features.
The growing prevalence of alternative synthetic products are endangering the existence of these forests and eco-friendly businesses in the Mediterranean region.
Natural cork is a renewable resource harvested from the live bark of the Cork Oak Tree, Quercus Suber L.
Areas along the Mediterranean coasts, from Western Europe to Northern Africa are climates where Cork Oak thrive.
Environmentally friendly harvesting
The Cork Oak is the only tree that can regenerate itself after every harvest. To ensure good tree health, strict laws and inspections are imposed on the sapling and on cork stripping. The year a tree was last stripped is painted on the bark to monitor its harvesting.
A Cork Oak tree is allowed to grow to a height of 120 centimeters and a circumference of 70 centimeters for approximately 20 years before its first harvest, and, thereafter, the tree is harvested once every 9 years during the standard harvest season of May or June through August. Skilled harvesters use a special tool to make precise incisions and then strip the bark from the tree. This material is then exposed to the elements for several months to purge the sap and stabilize the natural textiles.
At the factory, cork bark is boiled to remove the woody outer layer and also increase the bark's elasticity. The bark's then dried in factories for several weeks. The tree cork is then sorted by thicknesses, then further sorted into various quality ratings which decide the suitable manufacturing use and price.
Every harvest serves a purpose. The first "virgin cork" has a more irregular structure and is ground up for use in cork insulation, composition cork, and decorative items, including some corkboards. The second harvest, nine years later, results in "reproduction cork" that is usually granulated for use in flooring. Third and subsequent harvests generally result in the quality "amadia" cork that is made into wine stoppers, with excess from this "stamping" process being ground up for other uses including cork boards.
No part of the Corn Oak tree bark is ever wasted, oak trees are farmed, and oak does not suffer fatal damage through bark stripping.
