Solid Wood

LT 100 Internally open and internally inverted window

We independently develop solid wood composite system materials. The outer 1/3 to 1/4 of the solid wood profile is organically composite with high molecular weight wood fiber composite material (NFPC) and solid wood profile. The surface of the exposed high molecular weight wood fiber composite material (NFPC) profile is weather resistant, maintaining non fading, non deformation, and non aging for up to 15 years; Maintain the natural decorative properties of the wood on one side indoors.
