CHANGING THE CEILING FOREVER
Each Thin Sheet airfoil is a precision part – designed to integrate with a precision machine. These patent-pending airfoils move large amounts of air with minimum resistance for maximum efficiency. The aerodynamic profile results in smooth, silent airflow (in fact, it’s also the quietest ceiling fan in the world—at all speeds).
After multiple quality inspections and a seven-pass, solvent-free finish to highlight the natural grain, five sheets of Teragren Optimum 5.5 PureForm Bamboo Veneer are bonded in a hot forming press, then cut and sanded by hand by premium U.S. furniture craftsmen to create airfoils that meet the strictest quality standards. Only two companies in the world were found that could produce the airfoils with the necessary level of precision. All handcrafted Teragren Bamboo airfoils are tested for structural integrity and must meet high performance standards with regards to airflow rate, TAKING TERAGREN® BAMBOO TO NEW HEIGHTS thrust force and air velocity. Each piece must be able to withstand millions of rotations, starts and stops, numerous other stress tests, and meet rigorous specifications for integrity before being selected for use in the Haiku.
The result of this meticulous attention to detail and precision part manufacturing is a threedimensional airfoil with compound pitch. Technicians confirm the precise balance of every Haiku ceiling fan by individually fitting each airfoil, and Teragren bamboo offers a perfect finish with lasting durability.
A rapidly renewable resource with the tensile strength of steel, Teragren’s Optimum 5.5 bamboo stock is harvested every five and a half years, and new shoots spring from the same roots.
In addition to relieving pressure on degraded hardwood forests, moso bamboo’s leafy canopy releases 35 percent more oxygen than a comparable cluster of hardwood trees. In the renewing process, the bamboo plant grabs carbon from the air and holds it within its stalk and root system where, in nature, it is not released until the soil in which the plant decomposes is turned. Products made from bamboo take that carbon out of circulation. Teragren bamboo products harvested and manufactured correctly can last for many generations, keeping carbon locked up over the life of the products.
The multiple layers strike the perfect balance between support and softness. After multiple quality inspections and a seven-pass, solvent-free finish to highlight the natural grain, five sheets of Teragren Optimum 5.5 PureForm Bamboo Veneer are bonded in a hot forming press, then cut and sanded by hand by premium U.S. furniture craftsmen to create airfoils that meet the strictest quality standards.
For the specific carbon and glass fibre based composite materials often referred to loosely as 'composites', see Fibre-reinforced polymer.
A composite material (also called a composition material or shortened to composite, which is the common name) is a material made from two or more constituent materials with significantly different physical or chemical properties that, when combined, produce a material with characteristics different from the individual components. The individual components remain separate and distinct within the finished structure, differentiating composites from mixtures and solid solutions.
The new material may be preferred for many reasons: common examples include materials which are stronger, lighter, or less expensive when compared to traditional materials.
More recently, researchers have also begun to actively include sensing, actuation, computation and communication into composites, which are known as Robotic Materials.
Typical engineered composite materials include:
- Reinforced concrete and masonry
- Composite wood such as plywood
- Reinforced plastics, such as fibre-reinforced polymer or fiberglass
- Ceramic matrix composites (composite ceramic and metal matrices)
- Metal matrix composites - other Advanced composite materials
Composite materials are generally used for buildings, bridges, and structures such as boat hulls, swimming pool panels, racing car bodies, shower stalls, bathtubs, storage tanks, imitation granite and cultured marble sinks and countertops. The most advanced examples perform routinely on spacecraft and aircraft in demanding environments.
Composites are formed by combining materials together to form an overall structure with properties that differ from that of the individual components.

Hybrids are normally cold blends of polyesters (PE), vinyl esters (VE), and even polyurethanes or epoxies that achieve the optimal set of properties for a product. The ability to custom blend resins and various reinforcements affords the ability to optimize the properties very specifically.
Hybrids are very compatible with glass fibers and, depending on the blends, it’s possible to enhance the bondability with other reinforcements like carbon and even aramids.
Properties are very similar to polyester, vinyl ester, epoxy and polyurethane as described in those sections. Given the range of blending, properties can be highly tailored to your targets.
The strength-weight ratio is very impressive in comparison to metal because of the low starting density of 1.1 grams/cc for the resin alone.
