Internal aluminium or metal doors may look very impressive. Unlike wooden and PVC doors, aluminium doors are usually filled with solid spray foam, making them a good thermal insulator. Some doors are a combination of wood and aluminium, so they look very modern from the outside, yet warm and traditional on the inside. Aluminium on the exterior of a house is an excellent protection against the elements, it’s easy-to-maintain, and has a long lifespan. Wood looks beautiful inside a house and gives the sense of warmth and comfort. There are also combinations of materials that give a door low-energy and passive properties. When it comes to safety, aluminium doors hold the number one spot. Check out other advice we’ve prepared for you, and use our calculator to check aluminium door prices and the cost of installing one.
