1. What is welding?
Beautiful PU moulding is a great way to separate and define each room. With each design modeled after traditional plaster type mouldings, our light weight Polyurethane Mouldings give the same rich detail, yet at a fraction of the cost. Most moulding profiles can be partnered with our do-it-yourself Internal and External Corners(outside corners) that means no miter cutting for you and most rooms can be completed in ours instead of days. Another benefit of polyurethane is it will not rot or crack and is impervious to insect manifestations. our Polyurethane Cornice Corners,Internal Corners,External Corners,Outside Corners may be painted and drawn.
