FENSTELA DOOR & WINDOW WARRANTY
This express limited warranty is effective for product manufactured by Fenstela Doors & Windows . (“Fenstela”) after November 15st, 2024, extends to all original end users.
Subject to the conditions, exclusions and limitations of this limited warranty, FENSTELA is committed to delivering aluminium doors and windows systems that are built to perform consistently over time. Every product we manufacture and install reflects a careful balance between engineering precision, material quality, and attention to detail. Our warranty is designed as a direct extension of that commitment, providing long-term assurance for every completed project.
Each warranty is issued to the original customer and confirms that the installation of FENSTELA aluminium doors and windows has been successfully completed in accordance with our professional standards. This certification also serves as a formal acknowledgment of the coverage provided for both finishing and system performance.
FENSTELA warranty covers the essential aspects of product durability and functionality, including the quality and consistency of the powder coating finish, the structural integrity of aluminium profiles, as well as the performance of all system components such as sliding, folding, swing, and casement mechanisms. It also extends to the reliability of mechanical hardware, ensuring that every element works together as a complete system designed for long-term use.
FENSTELA provides a 20-year limited warranty for the powder coating finish applied to our aluminium doors and windows. This warranty ensures that the surface finish maintains its visual integrity and protective function under normal environmental conditions.
Over time, the coating is designed to retain its consistency in color and adhesion, preserving the original appearance of the product while providing protection against environmental exposure such as sunlight, humidity, and weather changes. This ensures that the aesthetic quality of FENSTELA doors and windows remains aligned with the intended architectural design, even after years of use.
FENSTELA provides a 10-year limited warranty covering the overall performance of aluminium doors and windows systems. This includes the structural integrity of aluminium profiles as well as the operational reliability of all integrated mechanical components.
Each system is engineered to function smoothly and consistently when used under normal conditions. From sliding and folding systems to swing and casement applications, every component is designed to maintain stability, ease of operation, and long-term durability. This warranty reflects our confidence that every installed system will continue to perform as intended throughout its lifecycle.
To ensure long-term performance and preserve the appearance of FENSTELA aluminium doors and windows, regular care and proper maintenance are essential. While our systems are engineered for durability, consistent upkeep will help maintain both functionality and visual quality over time.
Aluminium surfaces should be cleaned periodically using a soft cloth and mild, non-abrasive cleaning solution to remove dust and environmental residue. In areas with higher exposure to pollutants, coastal conditions, or heavy weather, more frequent cleaning is recommended to maintain the integrity of the finish.
The powder coating surface is designed to be durable, but it should not be exposed to harsh chemicals or abrasive materials that may affect its protective layer. Gentle cleaning methods will help preserve its consistency and refined appearance.
For optimal performance, all moving components such as hinges, rollers, and locking mechanisms should be kept clean and free from debris. Periodic inspection and light lubrication, when necessary, will help ensure smooth and reliable operation over time.
Glass panels can be maintained using standard cleaning solutions to preserve clarity, while careful usage of all systems according to their intended function will support both safety and long-term durability.
With proper maintenance and responsible use, FENSTELA aluminium doors and windows will continue to deliver performance, comfort, and lasting visual appeal for years to come.
