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.
