Questions about security entry doors

How can I secure my apartment?

Depending on the location of apartments, up to 90% of break-ins are carried out through the entry door, a smaller number via windows and balconies (on lower floors and below the roof). Therefore, a high-quality, certified security entry door is essential for every apartment’s security. If you live on a lower floor, where windows present a real risk, it is necessary to use window grills or security film on your windows. For complete peace of mind, it is optimal to have an electronic alarm that appropriately supplements your home’s mechanical security.

 

Do you provide sheet-metal lock armouring and installation of latches?

We do not perform any partial renovation of doors, because only a security entry door eliminates all weak points in a home’s entrance. A chain is only as strong as its weakest link and finding the weakness in various mended doors will take burglars only a few minutes.

 

What does a door’s security class mean?

The security categories defined by the new European standard contain six classes. Products in the lowest classes (1 and 2) are less expensive, but their functional durability is negligible, as they can usually be opened with an ordinary screwdriver within a few minutes. True security doors are those in security class 3 and above. For private and corporate buildings, security class 4 is usually the maximum class required. Products in security classes 5 and 6 are used for special applications of strategic importance (power plants, banks, military installations, etc.).

 

How can I discern the quality of a security entry door?

Find references and ask for recommendations. High-quality security doors always feature rigid metal construction with a full-area sheet metal cover, a steel skeleton and locking-bar system. Such doors are usually secured at ten to twenty points and are equipped with a high-quality lock cylinder that is resistant to drilling, blade impact, blade vibration and the SG method. Some doors are also equipped with special cylinder and lock protection.

Modern security doors must fulfil not only the strictest technical criteria, but also aesthetic criteria. Of course, they must have the appropriate certifications.

 

Why do you make all doors to order?

We always make security doors to order. Unlike some competing manufacturers, we do not cut up doors at the customer’s location or bending railing out of shape in order to make our products “fit”. In the fight against burglars, precision on the order of millimetres is the deciding factor in which tools a thief will be able to use. We all know how level and square our apartments and houses are, but an evenly embedded doorframe is a real rarity and deviations can sometimes amount to several centimetres. We considerate it irresponsible to install such an essential product as a security door without prior measuring and custom manufacturing.

How long are the delivery times?

The standard delivery time is from 14 days. We also provide express deliveries; the exact delivery time depends on the type of order and the particular agreement.

 

Can I have additional keys made by any locksmith?

Because we provide and install especially EVVA lock cylinders, which are among the highest-quality in Europe, it is possible to have additional keys made only by specialised firms. In order to have keys made, it is necessary to have your original key with a stamped number, the cylinder’s security card and your identification card. Without these documents, it is not possible to have a key made. This measure serves for your protection.

 

Are your doors certified?

NEXT security doors undergo a complex certification process. Security doors are certified not only by means of security and fire-resistance testing, but also through trials in a structural testing facility and the National Security Authority.

 

Do your doors also have soundproofing and thermal insulation?

The certificate from the structural testing facility reflects a set of numerous tests and trials including sound damping. NEXT SD 102F security doors are certified for sound damping up to the level of 40 dB.

 

Are you able to adapt the colour of a door’s interior side to the interior of a building?

NEXT doors have modular construction and therefore we are able to adjust the design according to the customer’s aesthetic requirements. You can view door surfaces and colour samples at our branches or arrange a non-binding consultation in the comfort of your home.

 

Is a fire-resistance certificate necessary?

Yes! Fire resistance is a necessary feature of modern security doors. In practice, doors with fire-resistance grade EI 30, 45 or 60 minutes are the most commonly used. In residential buildings, fire resistance of entry doors is stipulated by the law and therefore it is not possible to replace an existing door with a security door that is not fire-resistant.

 

What are the advantages of security doorframes or doorframes with reinforced hinges as opposed to ordinary doorframes?

Ordinary doorframes are designed for doors with maximum weight of 40 kg. Security doors are heavier. Therefore, we provide free technical consulting to our clients so that our specialist can assess the condition of their existing doorframes. The advantages of security doorframes are essential, as they are manufactured specifically for security doors. For example, the two-piece NEXT SF2A security doorframe has modular construction that not only guarantees more precise installation, but also the possibility of hanging a temporary door in the provisional part of the doorframe during construction so that the final installation of the security door goes smoothly and without structural intervention.

 

What if I lose the key to my apartment?

You can call any of our service numbers, where an operator will arrange a solution, which usually involves the immediate dispatch of a service technician who will replace the security cylinder with a new one.

 

Can I buy a lock cylinder for a NEXT security door somewhere else?

Of course you can, but first inform our technician of the exact parameters of the cylinder, especially its length and security class.

 

Can you also manufacture doors with non-standard dimensions?

We are able to manufacture doors with almost any dimensions; it is only necessary to comply with the valid standards and certificates.

 

Can your security doors be equipped with electronic accessories (automatic door opener, chip, reader, magnetic contact, etc.)?

We always prefer comprehensive security and our security doors are designed in such a manner that it is possible to connect them to any electronic system. We will gladly advise you regarding the selection of an electronic system that is suitable for your house or apartment.

 

Do you provide nonstop service?

Yes, we provide continuous service. Due to the fact that we have more than 100,000 customers, we place strong emphasis on the quality and speed of our maintenance services.
