WINDOWS EI30/EI60
Certyfikowana stolarka ognioodporna do budownictwa mieszkaniowego i komercyjnego. Dokumentacja, badania, wsparcie projektowe.
Wooden fire-rated windows EI30 and EI60 have been designed to limit the penetration of fire, smoke and high temperature for a specified period, which increases user safety and protects the building structure. The construction based on glue‑laminated timber provides high stability, durability and resistance to deformation even under demanding operating conditions. Fire-rated joinery is produced in accordance with strict standards and subjected to tests confirming attainment of the fire resistance class EI30 or EI60. Fire-rated windows can be used both in public utility buildings and in residential construction where specific fire protection requirements must be met. As a manufacturer of fire-rated windows in Kraków we provide comprehensive service including technical advice, production and installation of joinery adapted to the specifics of the investment.
78-110mm
profile thickness
Profile thickness (e.g. 70–86 mm) affects structural rigidity and allows using thicker glazing units.
0,9-1,5 W/m²K
thermal transmittance (Uw)
Thermal transmittance (Uw) indicates how much heat escapes through the window. The lower the value, the better the insulation and the lower the heating costs.
900 Pa
water tightness
Water tightness (e.g. class 9A) indicates resistance to water penetration during rain and wind. A higher class means better protection against leakage.
What makes the WINDOWS EI30/EI60 door stand out?
Windows meet the fire-resistance class requirements EI30 and EI60, providing effective protection against fire for 30 or 60 minutes.
Wood provides an elegant appearance to the joinery and allows fire-rated windows to be matched to the character of the building.
The use of glued laminated timber guarantees durability, resistance to deformation and a long service life of fire-rated joinery.
Wooden fire-rated windows also provide effective thermal insulation, supporting the building's energy efficiency.
Fire-rated windows can be custom-made to measure, in accordance with the project's technical and architectural requirements.

Why choose WINDOWS EI30/EI60?
Protection against the spread of fire
The special construction limits the spread of fire to other areas of the building, thereby increasing the level of safety.
Limitation of transmission of high temperature
EI30 and EI60 windows reduce heat transfer, protecting structural elements and interior fittings.
Maintaining fire tightness
Fire-rated joinery maintains its integrity for a specified period, preventing the passage of flames and hot gases.
Enabling safe evacuation
Fire-rated windows help extend the time for the safe evacuation of occupants in the event of a fire.
Compliance with building regulations
Fire-rated joinery enables compliance with the fire protection requirements specified in standards and regulations.

WINDOWS EI30/EI60 – Frequently asked questions
Find answers to the most important questions about our product
The EI30 and EI60 classes define the duration for which a fire-rated window maintains fire integrity and thermal insulation under fire conditions. EI30 means protection for a minimum of 30 minutes, while EI60 means protection for a minimum of 60 minutes. During this time the window limits the penetration of fire and high temperatures.
Fire-rated windows are used in residential, office, public and industrial buildings. They are particularly often used in locations requiring division into fire zones. They can also be used in single-family houses.
Yes, fire-rated windows can be made of wood and meet the requirements of classes EI30 and EI60. Appropriate design and the use of special materials make it possible to achieve the required fire resistance. Wood also provides an aesthetic appearance to the joinery.
Yes, every fire-rated window must have appropriate certificates and be tested in accordance with applicable standards. Certification confirms the attainment of a specified fire resistance class. This is required by building regulations.
Yes, fire-rated windows have a special design and components that increase resistance to fire. They differ in the materials used and the method of manufacture. They provide a higher level of safety.
Yes, fire-rated windows EI30 and EI60 can be manufactured to custom dimensions. This allows them to be tailored to a specific building project. It is standard practice in the production of fire-rated joinery.
Yes, fire-rated wooden windows provide very good thermal insulation. In addition to fire protection, they also contribute to improving the building's energy efficiency. Wood is a natural insulator.
Yes, fire-rated windows can also be used in single-family residential construction. Especially in locations requiring an increased level of safety. They are increasingly chosen in modern designs.
Yes — as a manufacturer of fire-rated windows in Kraków we offer comprehensive services including consultancy, production and installation. This ensures the proper performance of the joinery and compliance with technical requirements. Installation is crucial for maintaining fire performance parameters.
Production time depends on the specifics of the project, the dimensions and the technical requirements. Most often the process takes from a few to around a dozen weeks. Each window is produced individually in accordance with the project's requirements.
