2. Door leaf – special bent metal construction with 100% thermal insulation by 50 mm rock wool. Total width of the leaf is 75 mm. With protective boxes of the locks.
3. Reinforced, adjustable hinges with supporting bearings, covered with chrome-plated finishing caps – 2 pieces.
4. Protective pins for door hinges (16 mm Ø) – 4 pieces.
5. Insulation seals – 2 pieces.
6. Peephole.
7. Outside and inside door leaf finish – painted EDM board or WRB.
8. Outside architraves.
9. Inside architraves (if the door has to be fire-resistant).
10. Locks – optional, but one of the locks has to be no lower than 5th security class, see here.

12. The lock rods of three directions are additionally protected by steel tubes.

Door characteristics

Šarvuotos durys 9 Secure
Specially bent L-shaped 100 mm wide door frame is not only wider than that of ordinary armoured door, but also has 6 bending edges and thus is stronger than rectangular frames, which have only 4 bending edges. Moreover, the frame is fixed in the aperture by 16 plugs, which are protected from cutting by steel liners of 24 mm, thus there is no need to fix the door in concrete. Internal leaf construction is reinforced by rigid edges that do not allow deforming the door easily during burglary. One of the locks installed in this door model must be no lower than 7thsecurity class and protected by a drilling resistant manganese plate. Both locks are installed in protective steel boxes, and a separate protective sleeve secures each pin in the frame.

SKYDAS STANDART 3 RC4 hinges are reinforced and adjustable. On the hinges side there are 4 protective pins (16 mm Ø) that do not allow dislodging the door leaf if the hinges are cut.

The locks can be replaced without disassembling the door, so it is easy and fast.

Šarvuotos durys 01 Saves the heat in your home
As the bent profile leaf structure does not have closed cavities, it can be completely thermally insulated by 50 mm rock wool. The L-shaped bent frame and threshold ensure exclusive tightness as an additional seal is applied to the entire perimeter (two seals in total).

Thermal transmittance of SKYDAS STANDART 3 RC4 is 1.3 W/(m2K), i.e. the same like of 6-chamber plastic windows (the lower the transmittance, the more heat is held in). Therefore, this door is suitable not only for an apartment, but also for a private house (using the materials suitable for outdoor conditions).

Šarvuotos durys 02 Tight, good heat and sound insulation 
Due to the above mentioned full thermal insulation of the door construction, the sound insulation of the door SKYDAS STANDART 3 is 41 dB. This door is especially tight and therefore, perfectly shuts out the odours and smoke from the outside.

Šarvuotos durys 1 Fire resistant
With additional fire resistant components SKYDAS STANDART 3 RC4 can protect from fire for as long as 45 minutes and withstand the temperature of 1000ºC. The certificate was issued by Inspecta Estonia OU, No. 1527-CPD-0017. The boiler room doors of private houses already have to meet fire protection requirements. The fire can also spread from the garage.

Šarvuotos durys 03 Durable and lasting, convenient to use
All SKYDAS doors are manufactured by especially precise programmed machines Amada, which can process metal with the precision of 0.1 mm, therefore, their construction is precisely accurate and straight. As hinges with supporting bearings are used, the doors are easy to open and close, despite of heavier weight characteristic to metal doors. The tests indicated that after 200,000 cycles of opening and closing, the construction of the door remained completely intact.

As the internal construction of the door has no closed cavities, the entire metal construction is covered in powder coating, which ensures long-term surface protection from corrosion.

There are several options for the door finishing. Most commonly we use sustainably sourced EDM board (Extreme Durable MDF). It gives the freedom of design and is also water resistant, dimensionally stable and withstands severe atmospheric changes therefore is ideal for the finishing of entrance doors. For those who prefer wood-looking entrance door we offer – Water Resistant Board (WRB) made of natural hardwood veneers (okoume). This type of plywood is designed to withstand the most severe outside conditions. It‘s wood texture gives the luxury look to your door and does not limit your design ideas.

Under necessity, door finish can be easily replaced.

It is recommended to use galvanized steel RUUKKI for entrance door construction.

Šarvuotos durys 16 Simple to take care of
Painted door finish does not require any specific care and is easy to clean with non-abrasive cleaners.

Šarvuotos durys 16 Design possibilities
Choose a design from nearly 200 our finish carvings or we will manufacture a door according to an individual project prepared by an architect or us.

See GALLERY for door photos.

If you need warmer door designed specially for outdoors conditions, choose SKYDAS 2000.

However, if higher security level is necessary, choose security doors SKYDAS PREMIUM PLIUSwhich burglar resistance was tested and certified in an authoritative notified scientific research laboratory IFT Rosenheim, Germany. These doors were created applying the knowledge of the above mentioned laboratory of all possible ways and methods of burglary.

Technical data

The door is manufactured precisely according to necessary measurements.

Burglar resistance certificate is applicable to door measurements 2100×980 mm, outwards opening door. The height and width of the door can be increased by 10% or reduced by 20%.

Fire resistance EI45 of the fire resistant door is applicable to measurements up to 2100x 980 mm. If the height or width is increased by 15% (but not more than 20% of the total area), fire resistance will be EI30.
