Understanding Fire-Rated System Categories
Fire-rated windows and doors are tested to determine their fire resistance duration under standardised conditions. This rating, based on Integrity (E), Radiation (W), and Insulation (I) values, helps professionals select compliant systems for building safety. Understanding this classification system is crucial for specifying appropriate fire-rated systems during design, with the values 30, 60, and 90 indicating resistance levels (30, 60, or 90 minutes).
E-Integrity
Integrity signifies the duration for which the door and its components effectively impede the passage of flames and hot gases from the heated side to the non-heated side.
EW-Integrity and Radiation
Radiation mirrors the performance of Integrity by effectively resisting flames and smoke when exposed to fire on one side. However, it goes a step further by additionally mitigating the transfer of heat from the heated side to the non-heated side, ensuring enhanced protection and minimizing the impact of thermal radiation.
EI-Integrity and Insulation
Insulation stands as the pinnacle of fire protection, offering the utmost level of safety. Alongside upholding the same performance standards as Integrity, Insulation goes above and beyond by effectively preventing any heat transfer from the heated side to the non-heated side, ensuring unparalleled fire resistance and safeguarding the surrounding environment.

We have used SBW on several occasions over the years and always found their services very good, hence I’m a repeat customer. I’ve had bifold and sliding patio doors, front door, other exterior doors and replacement double glazing windows. Quality products, great customer service and aftercare.

Was very impressed both by the service and the product. After a bad experience with a previous window company, which you could feel the draft coming through after one month of instalation, I was skeptical to try different company. I am thrilled I found SBW GROUP. I had my windows done in April 2024 and the quality is above my expectations. The installation team was very organised, professional and considerate and we are very pleased with the results. Highly recommend them.
