• Today, we all know that security doors are essential for any home, especially with the rising crime rate in many areas. So despite the fact that the owners of such doors are becoming more and more, we observe a very unpleasant phenomenon: Very few place the right locks, thus greatly reducing the security of their door.

     

    A durable lock is really very important for all armored doors and for any home in general. In this article, we will show you the features that locks that ensure maximum security in security doors must have.

     

    An introduction to security door locks

    The lock is the heart of a security door. She is the one who controls all the security mechanisms she has. If the thief can't break the lock, then the only alternative is to knock on the door. If, on the other hand, he unlocks it, then he will simply enter as a master. There are many types of locks on the market, but we can generally say that their categories are: magnetic locks, keyless locks, electric locks, combination locks and locks that lock and unlock based on biometric data (fingerprint, eye iris etc.).

     

    Features of good locks for armored doors

    The most important feature of any lock is the so-called security plate. It is the only part of it that is directly connected to the "armament" of the door. This safety plate can be the weakest point of a lock, if it is not made of very strong and durable material or if it is not placed correctly on the door. So you should always make sure that your lock is at least done correctly, so it's a good idea to trust a professional and not take it. If you are buying a new door, ask them to install it for you directly.

     

    Of course, another very important feature is the key. The more complex or rare it is, the more difficult it will be for the thief to use a spade or create a key. So there are locks that open with special access cards as well as others that open with a password that goes into a special keypad. The latest technology is those that open with biometric data. If you are a more traditional type, there are also locks with conventional keys that are difficult to copy, if not impossible. My personal advice is to prefer a "searched" brand, as the known thieves may have "specialized".

     

    Many burglars use a drill to destroy and break a lock. To combat this problem, security lock manufacturers have created special "cases" with steel shavings inside the lock. When the drill reaches these cases it will be damaged or severely damaged by hard steel fragments, putting a glorious end to the burglar's attempts to break into your home.

     

    You can also invest in a high quality latch lock that has special pins for protection against saws inside its screw. Burglars not only use drills to remove locks from armored doors, they also often use saws. The special pins inside the locks that are designed to be resistant to saws can be rotated. So when a thief uses his saw, the pins turn along with it and make a hole in the water.

     

    Closing

    Remember that the lock on your door is the one that gives it its strength, since it will always be locked, but it can also be the Achilles' heel if its choice is not made correctly. Now that you know what the features of a good lock for armored doors are, you will be able to choose the safest one for your budget! πορτες ασφαλειας τιμες

  • In this article we will try to analyze the advantages and disadvantages of aluminum frames and PVC frames. Many ask us what are the best frames, aluminum frames or Pvc frames. How ecological are these materials and what constructions can we make for the balcony doors and windows of our house. Are plastic windows yellowing? Can we make recessed balcony doors, shutters or shutters? Truths and myths about the two materials for making frames and comparison in aluminum or PVC frames.

     

    Pvc Frames - Plastic Frames

    aluminum or PVC frames

     

    Pvc - plastic frames consist of polyvinyl chloride material, which is a composition of ( κουφωματα αλουμινιου αθηνα )ethylene (found in 43% oil), chlorine and some other substances, which with the addition of oxygen and their polymerization, becomes PVC. This material has been banned for the manufacture of several everyday items, such as children's toys, bottles, furniture, in most countries, while a relevant directive has been issued by Greenpeace Greece in relation to the construction of frames but also recently Greenpeace USA 

     

    PVC doors and windows are therefore made of synthetic materials, to which steel is added, in the center of the frame and the sheet of the window, in order to gain stability and eliminate distortions. The absence of steel or the use of other lower quality materials, which is a common tactic for cost reasons, can cause major problems in the most static of the window and it is advisable to ask for certification in case of problems. Note that steel does not appear, it is not visible, when the frames are delivered and the companies in Greece usually buy, from abroad, only the profile from Pvc, without the internal reinforcement, which they add later in our country. So let's look at the advantages and disadvantages of PVC frames in relation to aluminum frames for the construction of frames (doors and windows).

     

    Advantages

    They are economical because they are made of plastic materials.

    They have better thermal insulation properties.

    They have no joints because they are joined by heat-bonding.

    Disadvantages

    They cannot be made with plastic frames - pvc, sliding recessed frames and simple superimposed frames with screens. All PVC frames are imported (from Bulgaria, Austria, Germany) and in these countries no recessed frames are manufactured. In most cases, where you will find recessed frames from Pvc, they are Greek patents of poor quality and it is interesting to ask for their certificates.

    There are several cases of lesions, yellowing and bloating, due to their exposure to increased sunshine. This problem occurs with low quality PVC. The countries importing the raw material are usually countries with little sunshine in contrast to Greece.

    There is difficulty in making covers, ie shutters and PVC shutters. This is because in the countries where they are manufactured (Germany, Austria, Bulgaria) it is not customary to place covers. PVC shutters can be made in very small dimensions, with dubious quality and above all safety. The same is true of PVC shutters, which lack insulation inside their boxes, as is the case with heat-shrinkable aluminum boxes. Before you decide to buy shutters or shutters from Pvc (plastic) it is good to see some real works. In many cases of shutters, companies now suggest installing aluminum shutters.
