Energy-saving doors, fire-resistant doors, noise-protecting doors, protective doors

Doors are divided by target use into:

Energy-saving doors

Energy-saving doors are made with different thickness (up to 100 mm) with heat-insulating inserts (they are often made of mineral woold items) to save heat energy. Energy-saving doors include doors with exterior and sometimes interior coating withleather-substitute with heat-insulation gasket made of felt or other material.

Fire-resistant (fireproof) doors

Fire-resistant (fireproof) doors are not only special, they are also a part of interior. Today fire-resistant doors are made of different materials: wood, glass, steel, steel and aluminum profiles. Their colour scheme is also wide.

Noise-protecting (sound-proof) doors

Noise-protecting (sound-proof) doors are provided to reduce noise which enters the premises and goes out of them. The main difference of sound-proof door from a usual one is that it tightly adjoins not only door frame, but also floor. It is achieved with the help of different sealers and thresholds. Special sound-absorbing filler can be also inside the door.

Protective (shockproof, bulletproof, antirobbery, waterproof and other) doors

Protective (shockproof, bulletproof, antirobbery, waterproof and other) doors are often combined, i.e. they are made of different materials performing different functions (for example, metal-glass, metal-wood).
