What is inside a hollow metal door?
The infilling material can affect the impact resistance of the metal door panel, the overall sound insulation capacity of the door, the warmth retention capacity, and the whole service life.
Since the infillings are an invisible part, it is also a factor in the difference in the effect and cost of the door leaf. The main infillings include aviation aluminum foil, polyurethane foam, rock wool board, honeycomb board, etc.
Aviation aluminum foil:
Aviation aluminum foils are better than others in corrosion resistance and sound insulation and can be directly used for outdoor anti-theft doors, such as villa doors.
Polyurethane foam:
It is a foaming agent. This type of substance was previously used on the refrigerator door, which has a heat preservation effect and has a relatively low cost. It is a new type of material that is placed in the metal door, which belongs to the foaming agent after molding and can play a good sound insulation effect.
Rock wool board:
Rock wool is widely used in door fillings and has impact resistance, heat preservation, heat insulation, sound insulation, and moisture resistance. Advantages such as affordable price. The disadvantage is that the outdoor security door cannot be directly connected to it. Under the condition of sun and rain, it is easy to decay in quality.
Honeycomb paper:
The honeycomb paper is made according to the principle of the natural honeycomb structure. It connects the corrugated base paper into countless hollow three-dimensional regular hexagons by glue bonding to form a whole force-bearing part—paper core, and glue the face paper on both sides. It is a new type of sandwich structure environmentally friendly and energy-saving material at low cost.
