Thermalite Synthetic Shutters™

Thermalite™ Shutters are the best synthetic shutters available – they look and feel exactly like wood, but have some qualities that far surpass those of wood.

Synthetic Shutters in the Living Room

Made from polymer material, Thermalite™ is a solid, non-toxic, synthetic material. Because Thermalite™ is 100% synthetic, no natural resources are destroyed in the manufacturing process. Additionally, Thermalite™ is water resistant, fire retardant, and insulates more than three times greater than wood.

Thermalite's manufacturing process includes the patented Duraglide Louver Tension System, guaranteed never to need tightening or adjusting. The fastening system used to secure the tilt rod to the louvers is guaranteed never to loosen or to pull out.
