Venetian bass wood blinds have stood the test of time. Classic and contemporary, they can be suited for almost environment. The slats for custom-fitting wooden window blinds are made out of true bass wood, while Faux Wood blinds are made of high grade & lead free PVC (vinyl). 

Both wood and vinyl (PVC) blinds are effective window insulators, although wood is better at resisting temperature conductivity. The tighter the blinds fit in the window frames, the better they block heat/cold transfer through air movement or convection, creating a barrier between outside temperatures and your home's interior.
