These are 55 mm thick external doors filled with expanded polystyrene boards, which are characterized by very good insulating and acoustic properties. The leaf covering is made of anti-corrosion protected steel sheet, covered with high-quality foil resistant to UV radiation and weather conditions. Entrance structures meet EU energy standards for external doors and perfectly meet the requirements of our climate zone. As standard, they are equipped with two independent locks with three pins, three anti-burglary pins and three three-part hinges. The security standard and the thickness of the sheet metal used to produce the door leaf and frame ensure high resistance to burglary.

Convenient installation and 3-year warranty
The door leaf and frame are delivered to customers as the assembled set. Thanks to this, the door can be installed quickly and easily after unpacking. We offer the longest 3-year warranty period on the market for entrance doors.
Doors tailored to your needs
To meet our customers' requirements, we offer the possibility of making Polstar external doors to dimensions (width and height) tailored to individual needs.
The shortest production time on the market
The order processing time while ensuring high quality is one of our main advantages. We respect our customers' time and that is why we constantly improve our production and logistics processes. 3-4 weeks for single-leaf and double-leaf doors. 6 weeks doors with transom or aluminum sidelight.
Thickness of structural sheets
The door leaf is made of 0.8 mm sheet metal and the Polstar-Thermo steel door frame made of 1.7 mm sheet metal allows to achieve excellent stiffness and stability parameters of the structure.

Superior 55 Eco
Superior 55
This is a warmer version of the Superior model. The entrance door is filled with injected PUR polyurethane foam, providing much higher thermal insulation parameters than expanded polystyrene. The door leaf structure is based on a frame made of high-quality, waterproof hardwood plywood - it ensures mechanical stability of the door leaf in changing weather conditions. The outer leaf is equipped with two locks with three pins and three anti-burglary pins. The energy-saving door frame prevents the formation of thermal bridges thanks to a special, two-part structure divided by a plastic insert - it is equipped with a thermal threshold of the same construction. Outdoor models are equipped with three 3D hinges with a diameter of 15 mm, making adjustment much easier. As in the case of the Superior package, you can order entrance models of a specific height - the factory-made shortcut allows the production of doors to size, without cutting the leaf and frame.

Comfort 73 ECO
An entrance door model dedicated to energy-saving construction. The 73 mm thick door leaf was filled with polystyrene. The warm door frame, combined with the Roto aluminum threshold, thermal break and four-sided rebate, ensures the highest level of energy efficiency. It is possible to order an XPS foundation up to the threshold allowing for an additional increase in thermal insulation. External doors are equipped with three 3D hinges with a diameter of 20 mm, which are characterized by the ability to carry heavy loads, which significantly increases functionality and comfort of use. An entrance structure equipped with such a hinge does not tend to fall. Additionally, the hinges enable adjustment in three planes, which ensures symmetry of the position of the leaf in relation to the frame (up/down and left/right adjustment), as well as appropriate pressure of the leaf against the frame (third plane of adjustment). Two independent locks with three pins and three anti-burglary pins ensure a high degree of resistance to burglary.

Aluthermo 55
Energy-saving doors with a leaf thickness of 55 mm are an excellent choice for people who want to reduce their energy bills and increase the internal comfort of their home. The door leaf is filled with PUR polyurethane foam, which ensures excellent insulating properties, reducing heat loss and protecting against cold. The doors are equipped with an aluminum frame with XPS filling, which ensures high stability and durability of the structure. A multi-point strip lock is another element that affects the safety and comfort of using the door. This lock is very durable and effectively protects against burglary. The four-sided rebate improves the tightness of the door and also helps reduce noise from outside. The ROTO warm threshold is a solution that prevents the penetration of cold air and condensation of water vapor on the threshold. 3D hinges fi 20 are an element that allows easy adjustment of the door. The Aluthermo version is available without a top lock and rosette, while the Aluthermo Lock version has a multi-point lock with two independent inserts.
