Is it better to fill the security door with thin aluminum or polyester foam?

Aviation aluminum foil. In fact, aluminum foil is a material that fills the door with a honeycomb mesh structure, and the advantage is that it can withstand high temperatures of more than 2,000 degrees Celsius.

The disadvantage is obvious, the metal filler conducts sound and temperature quickly, which means that warmth and sound insulation are its shortcomings.

Polyester foam filling has better thermal insulation and sound insulation performance, and will melt at high temperatures, because many manufacturers will control the cost of filling in the door, and the environmental protection of foaming is very poor, and black smoke will melt at high temperatures, but there are also a few high-end manufacturers with imported green water-based foaming, which also ensures environmental protection problems. Of course, the relative cost is high, and the price is also high.

The security door filler includes: honeycomb paper, rock wool, polyurethane foam, aluminum foil.

Equipped with an anti-theft lock, it can resist abnormal opening under certain conditions within a certain period of time, and has a certain safety protection performance and meets the corresponding anti-theft security level.

The full name of the security door"Anti-theft security door"。It combines anti-theft and security performance. According to the provisions of the "General Technical Conditions for Anti-theft Security Doors", qualified anti-theft doors cannot be pried open within 15 minutes by using ordinary hand tools such as chisels, screwdrivers, crowbars and portable power tools such as hand drills, or open an opening of 615 square millimeters on the door leaf, or open an opening of 38 square millimeters in a semicircle of 150 square millimeters of locking points.

And the locks used on the anti-theft door must be a special lock for the anti-theft door with anti-drilling function that has been tested and qualified by the testing center of the Ministry of Public Security. The anti-theft door can be made of different materials, but only the door that meets the standard test and receives the safety product production certificate can be called an anti-theft door.

According to the anti-theft security level, it is divided into 4 levels, which are A, B, C, D four levels from high to low, decreasing in order.

It is mainly reflected in the intelligence of its key components (locks), including various electronic anti-theft locks that have begun to be widely used, such as fingerprints, passwords, IC card locks, etc. With the advancement of technology, in addition to replacing traditional mechanical locks with smart locks, the Internet of Things security door will also be combined with smart home systems with functions such as security, home appliance control, elderly and child care, etc., and can realize functions such as network alarm, video surveillance, data transmission and remote control, which are the embodiment of intelligence.
