More Details About Project This California hotel wanted to use overhead trellis to diffuse direct sunlight in the pool area. The major drawback to this architectural style, especially near coastal areas, is the difficulty in maintaining wood in that environment. DEC produced the overhead trellis beams in a wood textured FRP. This class 1 fire rated material is impervious to moisture and with the cast in woodgrain is unperceivable from wood, but it requires no maintenance over its life other than paint. The Hotel Valencia in San Jose offers a private restaurant and pool area where the guests enjoy the view. The resort management of this property appreciates the FRP for its maintenance free attributes that will last for decades.
