HFL windows are PVC windows that mimic the appearance of wood. 

In terms of performance, HFL windows are more durable and weather resistant than wooden windows. HFL windows are usually chosen by customers who want both a wooden window appearance and high-performance PVC. 

In terms of  the appearance, the welding of HFL windows is also different from ordinary PVC windows. HFL windows are usually modeled after wooden windows, connected at 90 degrees instead of 45 degrees. This determines that ordinary welding machines cannot complete such work. Therefore, Fenstek has launched a special HFL cutting saw, as well as an HFL welding machine.
