Case Study
SYMBI duplex one

Tysvaer and Kulp chose prefinished white fiber-cement siding from Allura, which gives the home a modern farmhouse look but eliminates the need for painting. They also wanted to add an organic feel to the exterior, so they used Lignia, a fast-growing softwood that is modified to have the properties of a hardwood. “The durability, stability, and environmental credentials of Lignia wood make it a perfect choice for the SYMBI Duplex One project,” says Lisa Ayala, Lignia sales manager for North America. Lignia wood is used on the bay window, front porch and stairs, and rear deck. | Photos: J. Loren Photography
