How Bamboo Becomes an Armstrong Ceiling Panel
Bamboo is being used more and more in interior finishes for its natural aesthetic
beauty as well as its contribution to sustainable design.
Unlike hardwood trees, bamboo is a grass that is renewably harvested over and
over from the same plant. Because it is rapidly renewable, bamboo used in
building materials and products can help them qualify toward US Green Building
Council LEED® Credit (MRc6).
Now, architects and designers have an opportunity to specify natural bamboo in
the ceiling plane. Armstrong is incorporating bamboo veneers into the creation of
new WoodWorks® ceiling panels:
1. Bamboo used for Armstrong ceiling panels is Moso bamboo – the main bamboo
species in China -- and is harvested as a renewable resource every 5-6 years.
2. The hollow bamboo stems are sawn - lengthways - into strips.
3. After the bamboo is cut into strips, but before pressing it into a block, some
strips are heat treated to bring out the natural sugars in the plant and create a
4. The natural or caramelized bamboo strips are then pressed against each other
horizontally (plain pressed) and adhered under high pressure. The result is a
panel or plank with the characteristic bamboo knots in a vertical grain pattern.
5. These planks are laminated into blocks, and then conditioned and soaked in
6. Bamboo veneers are then sliced from the blocks. Bamboo veneer is more
difficult to produce than conventional solid wood veneers, due in part to the
number of joints that reduce yield.
7. The bamboo veneers are dried, selected, and cut to create Grade A veneer
8. All selected Grade A veneers are backed with cellulose fleece to give the
product more stability and strength.
9. The natural and caramelized veneers are shipped to our manufacturing plants to
be used as face veneers with a clear semigloss coating. The result is
Armstrong WoodWorks Bamboo Patina (caramelized) and WoodWorks Bamboo
Native (natural) ceiling panels.
