The Dutch door is a heavy duty hinged door which is seamlessly welded using two marine grade aluminum sheets and insulated with foam. These can be built as an engine room door using sound down barrier insulation. This provides a weather tight door that is strong and durable to resist all the abuse and elements thrown at it. These are custom built to fit into any door opening. There are many options which will allow you to order a variety of finishes and a selection of window tints. They are produced with radius 4″ or mitered corners. Upgrades can include European TrioVing locks and additional dogs.
