FAQ

FREQUENTLY ASKED QUESTIONS

What is the difference between plastic front doors and plastic windows?

The entry doors feature a reinforced construction, more durable reinforcements, and are designed to withstand daily wear and tear. They allow for the installation of security hardware, multi-point locks, and various types of door panels.

The Uw value represents the heat transfer coefficient of the entire door—that is, the frame, door leaf, and panel. The lower the Uw value, the better the thermal insulation properties of the entire structure.

Doors can be equipped with multi-point locking systems, security cylinder locks, protective hardware, door handles, or electronic opening systems. We will recommend specific features based on the required level of security.

Yes. We offer a wide selection of door panels, wood finishes, colored films, glazing, handles and pull bars. This allows you to coordinate the doors with the windows and the overall appearance of the facade.

Yes, but only minimal. We recommend regularly cleaning the profiles, checking the seals, and lubricating the hardware and lock at least once a year. Proper maintenance contributes to a long service life and trouble-free operation.
