The filling of the security door is an important factor that determines its thermal insulation, sound insulation, fire prevention and anti-theft functions. However, some of the security doors currently on the market use paper shells for filling, and even toilet paper or horse manure paper.

In order to avoid the weight of the door is not enough, the manufacturer fills the mezzanine with cement or bricks, which makes the door look very heavy, but claims that it is because the steel plate is good.
At present, China has not banned the use of paper materials for the interlayer filling of the security door, but it must be honeycomb cardboard. Generally, the filler used in the regular brand of anti-theft door is mostly foaming agent, which can keep warm and sound insulation, and the disadvantage is that the fire resistance is poor. The high-end ones use slag wool, which has no problems with heat preservation, sound insulation, fire prevention and anti-theft.
Security doors made of these two materials have excellent thermal and acoustic insulation functions. The anti-theft door filled with paper shell and honeycomb paper is a low-grade product and does not have the performance of sound insulation and heat preservation. EMO Renovation Platform.
In order to distinguish the filling of the anti-theft door, consumers can take a look at it when installing the anti-theft door, generally unscrew the cat's eye from the door to see what is inside, if there is a cat's eye has been installed, and it cannot be screwed down, you can also see it when the door is locked. In addition, it is best for consumers to ask the manufacturer to indicate what kind of filling is used when signing the contract, so that if the filling is found to be wrong during installation, they can ask the manufacturer for explanation.
You can use this practice.
After the installation of the anti-theft door, the gun and the wall are not necessarily very, very suitable, so there are some gaps, but this gap may be able to make the outside wind through the gap to the home, so you use styrofoam to fill the gap, and later outside, it is okay to use cement wind speed. >>>More
After fixing it with an expansion screw. It is also advisable to pour fine stone concrete on the door frame.
Look what you have, it is generally foaming, because it is easy to do, I have been working in construction for several years, I personally think that if the cement is too small first, the new and original walls are not easy to fasten, since it is a door back and forth switch sometimes force in the big point, it is easy to make the new cement fall off.
The soft bag is well punched and lasts for a long time. The time used with glue is relatively short, because the glue has a time limit, and the glue will not work after the deadline.
Generally, if the gap is about 1 3cm, it is good to use styrofoam, and if the gap is relatively large, you have to pour cement.
